Crucial Adrenaline review: SSD cache drive speeds up your PC

May 11th, 2012

Computerworld – If you want to speed up your PC but don’t want to deal with a new hybrid hard drive, one way is to simply add an SSD cache drive to your PC. These drives aren’t meant to be mass storage devices; instead, they cache your most frequent application operations and thereby improve performance.

Crucial Adrenaline

One of the newest SSD cache drives out there is the 50GB Crucial Adrenaline, which sells for $100. (The drive actually has a capacity of 64GB, but 14GB is used for internal housekeeping.) For no more work than it takes to pop open your computer, install the SSD and load some management software, Crucial says you can get up to an eight-fold increase in the performance of your existing hard drive on a Windows 7 PC.
In the box

Like almost all SSDs, the Adrenaline is a 2.5-in. drive, which can be problematic for most desktop computer cases because they’re engineered for 5.25- and 3.5-in. drives. (The 2.5-inch form factor is typically associated with laptops and other smaller devices.) Crucial supplies you with a bay adapter and the data cable you’ll need to install the drive.

There’s no documentation or software included in the package, but you’ll need both. A video and a PDF version of the installation guide can be found on Crucial’s website. I would encourage you to download that PDF and look through the list of requirements and exclusions. They are more detailed than I could go into here.

The PDF includes a link allowing you to download Dataplex software. Dataplex is the caching algorithm that the Adrenaline drive uses to determine what you are doing on your computer and what should be cached as a result. You’ll need the software key supplied on the small placard in the Adrenaline box to initiate the download and, later, to install the software. Don’t try to install Dataplex until the hardware is in place.
Installation

I installed the Adrenaline drive into a Max Force Revolution 2600K PC equipped with an Intel Core i7 2600K processor (overclocked to 5GHz), 8GB DDR3 RAM, a dual 1TB hard drive, dual EVGA GTX-570 SLI graphics cards and 64-bit Windows 7 Home Premium.

The Adrenaline installation offered no surprises. If you’ve ever installed a hard disk, you won’t have any problem — once the SSD is attached to the drive bay adapter it follows the same general procedures. Based on my experience, however, I’d recommend connecting the data and power cables to the Adrenaline before you install the assembly into your drive bay. That may not be necessary, but the space between the back of a hard drive and the back of your computer’s power supply is often only a few inches and it’s usually crowded and dark.

The Dataplex software installation is also routine. Once it is installed you’ll need to reboot your PC for it to “grab on,” start analyzing how you’re using data, and begin to speed things up.
Performance

You may not notice any difference whatsoever during that first reboot. Dataplex relies on a statistical preponderance of activity to “learn” what needs to be cached; that first time just provides a baseline. By the second — or possibly third — reboot, you should notice a reduction in the time it takes.
At a Glance
Crucial Adrenaline
Crucial
Price: $92-$114
Pros: Low price, easy installation, almost guaranteed results
Cons: Requires a software key

In my own real-world comparisons, the PC’s boot time decreased by about 10 seconds the second time I rebooted it. Loading the game Company of Heroes, with all its background information, was even less of a wait — it took about a fifth of the time it normally takes. (This despite the fact that progress in a game can alter the information that will be cached, reducing the effectiveness of the Adrenaline.) Microsoft Word, which is a much less graphics-intensive application, popped up on screen like a genie from a lamp, especially when loaded with a previous document.

As scenarios change (a different Word document, a different battle level in Company of Heroes, or even a different application), you will notice variations in speed as the Adrenaline relearns what it needs to preload into cache. And while you may never see data rates improve “by up to 8 times” as Crucial suggests, I did see boot times decrease by as much as 40%, while application and game loading improved anywhere from 20% to 40% (or even as much as 60% in a few cases) over their noncached rates.
Bottom line

The Adrenaline drive doesn’t work in a vacuum. Any gains you might see will depend upon the overall speed of your computer, the speed of your disk interface and the type of applications you run. However, even a 10% to 20% improvement, given the Adrenaline’s low cost, is worth the price of admission. As a result, I give the Adrenaline an unabridged two thumbs up.

Helium 1TB portable hard drive offers hardware encryption

April 24th, 2012

The Iomega Helium is a sleek, pocket-sized portable hard drive with a durable aluminum case. The Helium’s compact design and matte silver appearance is the perfect aesthetic complement to the Mac, but it boasts only a USB 2.0 interface.

The Helium comes formatted with HFS+ and works with Time Machine right out of the box. Also included with the drive is a Y-shaped USB cable to support connectivity with older Macs, whose USB ports may not draw enough power to spin the drive.

The drive also offers hardware encryption, but it is not active by default. To enable this extra security, you’ll have to download the Iomega Encryption Utility software and install it. The one drawback to this is that, in order to access your drive across multiple machines, you must install the utility on each individual computer that you plan on sharing the drive with.

When put through our standard hard drive tests, the Helium’s performance was mediocre, averaging a write time of 26.5 MBps, and a read time of 31.6 MBps in the AJA System Test. When writing a sizeable 10GB file, the drive averaged 27.1 MBps while its mean read speed was 33.9 MBps. Additionally, the Helium averaged 26.7 MBps when writing a 10GB folder, and 29.1 MBps to read that same folder. While these aren’t the slowest read/write times we’ve seen, they aren’t really impressive either.

The Helium comes in both 500GB and 1TB capacities, priced at $150 and $200, respectively. (We tested the 1TB version.) At these prices, you can find other hard drives that are more affordable and offer more connectors.

Macworld’s buying advice

All in all, the most exciting part about the Iomega Helium is it’s appearance. However, if aesthetics aren’t your main concern when purchasing a new drive, keep in mind that there are more versatile drives on the market for roughly the same price. The Western Digital My Passport Studio 1TB ( Macworld rated 3 out of 5 mice ), for example, sells for about $170, has both USB 2.0 and FireWire 800 connectivity, has security software, and produced similar test times.

Commodore Amiga Mini PC revealed: Core i7, 16GB of RAM and a Blu-ray drive

March 22nd, 2012

Yeah, an optical drive. You know, for folks who still appreciate the passing fads of life. Bitterness aside, Commodore is following up its retro-fabulous C64x with a new small-form-factor PC, the Amiga Mini. While not much of a looker, this box houses a potent 3.5GHz Core i7-2700k CPU, 16GB of DDR3 memory, NVIDIA’s GeForce GT 430 (1GB), a WiFi radio and a 1TB HDD that can be swapped out for a 300GB or 600GB solid state drive. There’s a slot-loading Blu-ray drive by default, internal space for a pair of 2.5-inch drives and a predictable Amiga logo burned right onto the front panel. Unfortunately, the well-specced base model tips the pricing scales at $2,495, but that does include a copy of its Commodore OS Vision. The company’s also revealing the C64x Supreme, the new VIC mini and a more powerful VIC-Slim keyboard computer (which now includes an HDMI output), all detailed in the presser past the break.

Hard drive pricing still high in SA

March 6th, 2012

Hard drive pricing is still high internationally, following flooding in Thailand that was described as the world’s fourth costliest natural disaster by the Work Bank.

Local pricing has followed the international trend and remains far higher than pre-flood levels in September 2011.
Causes of high pricing

The main reason for higher than normal hard drive pricing is the flooding Thailand experienced in September 2011. Thailand is responsible for half of the worlds hard drive production, both in the form of component production and product assembly.

Manufacturer Western Digital were hard hit by the flooding, with one of their plants submerged in water until mid-November. Component production in this particular factory only resumed in late November.

Toshiba also suspended production at various Thailand-based factories, while Seagate, who source components from Thai based companies, faced component shortages.

Rand devaluation against the Dollar also played a part in higher hard drive pricing since September 2011. The exchange rate for the beginning of September sat at R7.03 to the dollar. This skyrocketed to a peak of R8.52 in late November, before dropping slightly to current levels of around R7.55 per dollar.

Craig Brunsden, Executive Director at AxizWorkgroup notes that the flooding created knock-on effects that have also influenced pricing.

Brunsden said that the effects were worsened by “traders/speculators and big players buying up available supply and making the shortage worse by artificially holding supply off the market, in the expectation that money will be made in the short term. Thus, the actual effect of the supply is made worse by the aftermarket issues.”
Continued effect on pricing

Issues that led to the spike in hard drive pricing continue to have an effect on the local market according to Mahomed Cassim, CEO of local hardware distributor Esquire.

Cassim noted that the price of hard disk prices had at times escalated by almost 200 percent since late last year. This is having a “marked affect” on the sales of desktop PCs and notebooks as resellers and end-users remain unwilling to pay the current price.

Brunsden from AxizWorkgroup also commented on the consumer side of things, saying that consumer demand wasn’t really affected. “Most of the demand issues happened in the supply side rather than the [consumer] demand side, where distributors and traders were buying up any available stock,” said Brunsden.

He continued by noting that while consumer choice may have been affected, PC availability hasn’t. “Local South African brands and certainly component distributors have been affected, and thus a consumer’s choice of brand may have been affected, but PC’s have been available throughout the shortages.”
How long can we expect hard drive pricing to remain high?

Brunsden noted that hard drive pricing is already reducing as supply continues to improve even though the situation is not quite back to normal yet.

“Forecasts are that the situation will be back to normal by mid-year,” Brunsden concluded.

Cassim echoed Brunsdens comments about continual price reduction, though he noted prices are still high. “Although the marketplace is starting to see price reductions across the board, disk drives are still about 60-90% more expensive than they were before the flooding,” concluded Cassim.

Big data helps drive math Ph.D.s to IBM

February 20th, 2012

Big data, and the need to analyze the information that’s collected from every interface and sensor imaginable, is increasing employer demand for people with backgrounds in statistics and mathematics.

The range of companies hiring people with math skills is on the rise, and that trend prompted a top IBM official this week to boast about that company’s record of hiring mathematicians.

“We are the largest employer of Ph.D. mathematicians of any company in the world,” said Steve Mills, a senior vice president at IBM and the company’s group executive for software and hardware.

Mills made that claim on Wednesday while delivering a presentation at the Goldman Sachs Technology and Internet Conference, which focused on big data and other IT trends. His talk was primarily about the need to harness the torrent of big data and turn it into valuable information.

Whether IBM is truly the largest private employer of Ph.D.s is not something that Richard Cleary, a professor of mathematics at Bentley University in Waltham, Mass., can easily verify. He’s an author of the “Annual Survey of Mathematical Sciences in the U.S.” (download PDF), which looks at the employment status of mathematics graduates. It’s a project undertaken by four mathematics groups, including the American Mathematical Society.

But Cleary said “the demand for [people with big data analytics skills] has certainly made a huge difference,” in the employment market for people with mathematical skills, particularly those who have backgrounds in statistics.

At the Goldman Sachs conference, Mills explained IBM’s approach to real-time data analytics. It begins with a proof of concept — an example might be a study that reveals patterns in maintenance work at a power utility and shows how changes in preventative maintenance could deliver a return on investment in months.

But a proof of concept can take months, and Mills said one proof of concept that IBM put together for an oil company took two years. “Two years of persistence,” he said, “and we are now doing 44 oil platforms in the North Sea as a result of proving that we could do it on one.”

Mills said if IBM can do analytics for a power grid, it could do analytics for a water supply company or a transportation system. They all intersect, he said, adding, “we build a knowledge base one on top another.”

IBM is investing in areas such as astrophysics, weather forecasting and genomics “because of the intersections and overlaps with our core business,” Mills said.

“In many cases, it is the same math; it’s not like someone has invented new fields of mathematics,” he said.

At one time, the major employers of mathematicians were insurance and pharmaceutical companies, Cleary said. But there is a growing range of companies that are hiring people with mathematical training, including marketing firms and companies that use CRM tools.

“I’ve seen people being hired by grocery chains,” Cleary said. “That didn’t used to happen.”

Mathematicians who are in especially high demand are those who have expertise in business, computer science or other disciplines in addition to their quantitative skills, Cleary said.

Acer Aspire S3 Review

January 20th, 2012

The Acer Aspire S3 looks very nice in the product photos, and it is often associated with Ultrabooks because this type of design, which is inspired from the Macbook Air, has been used by many PC manufacturers in their recent designs. I like the new look very much, and I have been pretty bullish about Ultrabooks, at least much more than I ever was about Netbooks. Although Ultrabooks often share a similar hardware platform from Intel, they differ more than one may think, and depending on how they were designed, the end-user experience can be very different from one model to the next, so don’t let the superficial resemblance fool you. In this review, I will tell you how it felt to use the Acer Aspire S3 and we will look at what I felt was its strengths and weaknesses.

Industrial design

The Acer Aspire S3 Ultrabook has an agreeable design. It is thin, compact, and light. The loaner unit that we have even has a custom paint job that was done for Intel. The case seems to be built with a Magnesium alloy, which is a classic material for laptops and notebooks. Overall, it feels rigid enough, but there is a little bit of “flex”, especially with the display – it’s not as flexible as the Toshiba Ultrabook Z830 whose screen is *very* flexible, but we’re definitely not in the rigidity territory that the Macbook Air or Asus Zenbook are in.

In the back of the computer, you will find one HDMI port, two USB 2.0 ports, and the power connector. This is a good placement if you mainly use the computer on a desk as there won’t be any cables popping out from the sides, but if you need to plug and unplug things regularly, this may be a bit annoying. For example, we often use a 3G USB modem, and with the USB port in the back, it is possible (or probable) that backwards tilting would apply pressure to any USB device. You’ll have to think about this a little, and decide what works for you.

Because most of the ports are in the back, the sides are left clean with just a 3.5mm audio jack (left) and a full-size SD slot on the right (see photo gallery at the bottom).

Overall, I found the build quality to feel a bit “plastic”, and I think that Acer should improve upon this, because with its XPS 13 Ultrabook ($999 with 128GB SSD), Dell has a much nicer (partial) carbon-fiber construction and a better “soft touch” finish wherever carbon-fiber is not used. The HP Envy 14 Spectre (see Envy Spectre 14 demo) is also extremely nice, and the build quality is even higher than the XPS 13. However, it is much more expensive, and at 4+lbs, it is heavier.

Keyboard (average, no back light): for the most part, the keyboard is decent and there are no major complaints. The only thing that should really be different are the arrow keys. They feel tiny, because they *are* tiny. I don’t know for you, but if you type a lot of text, chances are that “Shift/CTRL + arrow” is a pretty big deal because that allows one to quickly navigate within a sentence. Also, I wish that there was a backlit keyboard, but this is not the case. Again, some people care, while others don’t. Find out in which category you stand.

Trackpad (above-average): The trackpad is “OK”. It’s not super-smooth, but it’s better than most trackpads, so I would say that it is above-average, but, not quite high-end or anything like that. It gets the job done and is definitely good enough and big enough.

Display (average): the display is OK, especially If you look at it straight-on. The view angle is not great and colors start changing rapidly as you move around, but this is a widespread behavior for computers in this category. What I like the most about the display is the ability to recline very far back. This can be great in airplanes or in other situations where you need that extra tilt that most laptops don’t have. This is definitely a plus.

In terms of processing performance, the Acer Aspire S3 processor does fairly well. For instance, when compared to my first generation Macbook Air, it is about 2X as fast in raw performance, which is as fast as the Samsung Series 9, according to Geekbench.

That said, I have to stress that synthetic benchmarks don’t tell the full story. Perceived performance is much more important to the end-user, and things like pre-loaded software (bloatware) or a slow disk can affect performance drastically. Here, the 5400rpm drive clobbers the end-user experience when compared to SSD-equipped competitors. The boot time and shut down speed is 5X or 6X slower, and the overall system responsiveness is lower as well.

Boot/wake-up/shut down speed

Shut down: 48 sec
Boot to browser: 60 sec
Wake-up from sleep: <2 sec
Battery life (fair)

For these tests, I have adjusted the power settings to make sure that the user experience is good enough. For example, the computer can play the test .mp4 1080p movie in Power Savings mode, but YouTube required switching to the more demanding Balanced Mode in order to get a smooth frame rate.

60mn of 1080p MP4 video playback used up 29% of the battery (download it here: gt5rpe3trailer_fixedv11_1080.mp4)

60mn of 1080p Youtube playback (WiFi) used up 40% of the battery (actual video: http://www.youtube.com/watch?v=_dJCLaoBZvM)

60mn of doing nothing (Display at 50%, no apps running) used up 18% of the battery. This is very important because this means that in the best-case scenario, the computer can stay on for about 5hrs, which is fairly good, but there are better options.

Charge time: recharging is as important as the battery life itself, because a quick charge can make a world of difference. It is clear that battery capacities won’t increase dramatically for any given size, but rapid-charging is already a working solution for industrial purposes, so consumer electronics will be next. to reach a full (100%) charge, the Acer Aspire S3 takes about 2 hours and 45 minutes, but if you are on a clock, stop at 90% (1hr 50mn) because that’s when things start to slow down dramatically. This is not uncommon for batteries, but depending on laptops there are different behaviors, so it’s definitely worth checking out.

In the end, the battery life is fair, and it’s surprising what one can get out of a 3-Cell battery these days. You can watch 3 hours of 1080p video, and that’s a fair amount for a laptop. Tablets can go as long as 10 hours, but it’s clear that they don’t have the chops to run more demanding Windows applications. Also, most (older) laptops in circulation now would probably die shortly after the first hour of 1080p video.

Misc

Webcam: the webcam quality of the Acer Aspire 3 is relatively low, which is unfortunately quite common in laptops. Even in good lighting conditions, the response time/frame rate is low, so I am guessing that the camera is slowing the shutter speed to compensate for the lack of light sensing capabilities. It’s never a good sign.

Audio: the speaker quality is pretty good, especially for a laptop this size. In a quiet environment, watching a movie, or listening to music is enjoyable. In a noisy environment (trade show, noisy cafe…) this could be more challenging.

Conclusion (needs to kick it up a notch)

The Acer Aspire S3 is an interesting laptop, which delivers good raw compute performance that is comparable to other laptops using the same Intel Core i5 24xx platform. However, the choice of using an mechanical hard drive (HDD) will put it at a significant disadvantage when compared to competitors who have opted for a Solid State Drive (SSD) because the SSD seek-time is nearly infinitely faster. SSD is a critical component of perceived performance in a computer. If you can afford one, get one.

If Acer could justify it with a much lower price point, there would be some grounds for debate. However, Dell has an offering that is just $100 higher and features a smaller form factor, a better display, a 128GB SSD, better build quality and… USB 3.0.

Interestingly, some competitors don’t offer the HDD option at all, so if you need a lot of storage (300GB+), and/or want to save a buck, the Acer Aspire S3 can be a slightly cheaper option. My personal take on this is that if you *really* need more than 128GB, you way want to consider a laptop with an SSD drive and use USB 3.0 for the additional storage.

In the end, the Acer Aspire S3 does look good, but in the current competitive landscape, this computer should be priced at $749, and not at $899. If you are willing to spend close $1000, there are simply much (much!) better options out there. I hope that this Acer Aspire S3 review has helped you form an opinion about this computer. If you still have questions, please leave a comment, and I will try to address it asap.
