Ubuntu finally embraces solid state drives as it preps for mobile push
Ubuntu is finally getting around to adding TRIM support, a pretty basic feature of most modern OSes. It's an essential command for maintaining the performance and health of solid state drives, since they operate in a fundamentally different way than your standard spinning-platter. This function allows an operating system to tell the drive which chunks of data are no longer necessary and are ready to be erased or over-written. That may sound a little obtuse, but essentially it means the disk needs to perform less writes, resulting in faster performance, longer life and less performance degradation over time. Windows added support way back in 2009, while OS X followed in 2011. Even Android jumped on the bandwagon back in July of this year, but Linux has lagged behind. Experimental support was added to the Linux kernel in 2008, but the feature is turned off by default due to performance concerns. And the option to enable it requires at least a moderate level of command line ninjutsu. Canonical has put a lot of work into getting TRIM support up to snuff, and finally feels it's ready for prime time. With the next version of Ubuntu, 14.04, it will be enabled by default, finally allowing its dedicated user base to fully realize the benefits of speedy, silent, power-sipping solid state storage. While the move is certainly later than many would have hoped, it comes at an opportune time as the company plans to make a serious mobile push. And, as we all know, solid state reigns supreme in the tablet and smartphone world.

Android 4.3 supports TRIM, improves performance on Nexus devices
It's no secret that many Android phones and tablets show a decrease in performance over time. Nexus devices are not immune -- it's particularly noticeable with the original Nexus 7. Our friend Brian Klug over at AnandTech discovered an interesting tidbit while testing the new and improved Nexus 7: Android 4.3 supports TRIM. What this means is that Google's mobile OS can now instruct the flash storage controller when to collect / recycle unused data pages / blocks. The net result is that devices running Android 4.3 will no longer become sluggish with time -- in fact, existing Nexus handsets and tablets will see performance improve after the update. It also looks like Jelly Bean invokes TRIM maintenance once within a 24-hour window (after one hour of inactivity), and only if the battery is 80% full (30% when charging). Follow the source link below for all the details.

TRIM or RAID 0? SSD owners will no longer have to choose
Owners of multiple SSDs will be familiar with this dilemma: do you opt for RAID 0 to put all those precious GBs to use, or do you go for AHCI mode in order to gain TRIM support and maintain performance over time? Well, the next release of Intel's RST should support TRIM for RAID 0, so switching to solid state storage will become an even smarter decision than it is right now. [Thanks, Brian]

Corsair unveils Performance Pro Series SSDs, loads 'em with 6Gb/s Marvell controllers
SandForce-equipped SSDs are seemingly all the rage nowadays, but lest we forget that others, like Marvell, have some peppy controllers of their own. Step up Corsair, who's just announced its new Marvell-equipped line of SATA 3 Performance Pro Series 6Gb/s SSDs. These 2.5-inch storage slabs can achieve 515 MB/s read and 440 MB/s sequential write speeds, and sports a TRIM-like "built-in advanced background garbage collection," which company deems helpful for RAID setups. Notably, desktop users will be pleased to know that the drives will mount into 3.5-inch slots via an included adapter. If you're interested, $280 will snag you a 128GB version, while $530 doubles the capacity to 256GB. You'll find more details in the press release past the break.

Keeping SSDs in TRIM: doing the math
Love Apple gear? Like math? TUAW's Doing the Math series examines the numbers and the science that lie behind the hardware. One of the new features we first saw in the developer beta of Mac OS X Lion back in February is long-overdue in this correspondent's humble opinion: it finally supports TRIM on solid-state drives. TRIM (which, despite the capital letters, isn't an acronym) is a way to speed up SSD access by performing important housekeeping tasks in the background or on file deletes, rather than leaving it until the user is writing data to the drive. Since then, TRIM has also appeared in 10.6.6 for new Macs with Apple-supplied SSDs only, and with third-party tools, it's now possible to get TRIM running on any SSD under 10.6.7. This raises the question: what exactly is TRIM, and why does it matter? If you've been wondering what this seemingly arbitrary abbreviation is, and why it matters, then I'm here with my best Science Hat on to remove all that wonder (as we scientists so often do) and replace it with cold hard fact.

Mac OS X Lion has TRIM support for SSDs, HiDPI resolutions for improved pixel density?
As you'd expect, developers have wasted no time in tearing apart the Mac OS X Lion preview, and in so doing they've allegedly discovered some intriguing things -- namely, support for the SSD-wiping TRIM command, and a series of high-DPI display modes which would allow for icons and UI elements with twice the graphical detail -- which could mean a PC-sized Retina Display. The former doesn't sound like the most exciting upgrade, but it's truly a boon for Mac users with solid state storage, as TRIM can greatly improve write speeds in compatible drives. As far as the improved pixel density rumors are concerned, it's not clear whether Apple's actually looking at doubling display resolutions in new computers (9to5Mac imagines a 15-inch MacBook Pro with a 2880 x 1800 screen) or whether Apple's simply moving to maintain icons that are precisely the same physical size across all its displays -- which would make fantastic sense for a touchscreen UI, by the way.

Kingston debuts 96GB SSDNow V+100 solid state drive, complete with 25 percent performance boost
Another week, another SSDNow drive. This go 'round, Kingston's trotting out a midrange 96GB version of the SSDNow V+100, which promises to offer a 25 percent increase in performance over existing V+ units. Furthermore, this guy has an enhanced 'always-on' garbage collection feature, which purports to clean redundant data from the drive to prevent performance degradation and maintains the drive over its life cycle. Thankfully for you dual-boot users, the garbage collection scheme operates independently from the OS -- in other words, it works with both modern, TRIM-supporting systems such as Windows 7, as well as older legacy OS' such as Windows Vista and XP that do not support TRIM. The 96 gigger carries an MSRP of $290, while a 64GB unit can be had for as little as $220 and a 512GB version for a staggering $1,900.

Viking Modular's SATADIMM jacks an SSD into your memory slot
Explaining the differences between DRAM and non-volatile storage is about to get that little bit harder, thanks to Viking Modular. The company's decided to "borrow" the DIMM form factor for its latest enterprise SSD offering, equipping it with a 240-pin array to draw power from your spare memory slots. Of course, you'll still need to hook up a SATA cable to get data flowing to this SSD -- at a very respectable 260MBps for both read and write -- but we must admit we're in love with the very idea of it. This new design offers another option for consolidating storage right onto the motherboard and should help case modders yearning for ever-slimmer enclosures. Alas, the SATADIMM is only available to enterprise and OEM clients for now, but we can't think of any reason why it won't test the consumer waters as well -- if not by Viking, maybe someone else? [Thanks, David]

Corsair's 100GB Force SSD scorches the test bench with its blazing speed
The name's Force, SandForce. Corsair's making it kinda easy on us to spot its first SandForce-controlled SSD, and there's no reason it should be bashful about it, given that the SF-1500 is currently the fastest SSD processor around. The F100 in question has the SF-1200 onboard, offering a lesser 285MBps read and 275MBps writes (oh, such measly specs!), but that also means you might, might, actually find a way to afford one. The TweakTown crew took one for a spin recently and were happily surprised to find little in the way of performance difference between SandForce's supposedly enterprise-class SF-1500 and consumer-class SF-1200 -- both sped ahead of the Intel X25-M G2 and Indilinx Barefoot-controlled drives. The speed conclusion was clear cut, and with pricing for the 100GB F100 projected to be as low as $400, the value proposition doesn't look too bad either. The 200GB variant is expected to land somewhere around $700 when Corsair's Force SSDs make it out to retail in a few days' time.

NVIDIA's Optimus uncovered in Sony VAIO Z, along with TRIM support?
Sony's illustrious VAIO Z may have a so-called "Dynamic Hybrid Graphics System," but NVIDIA's Optimus it is not. Or is it. Notebook Review's own igorstef started digging deeper within the laptop's switchable GPU setup, and lo and behold, it sure looks as if Optimus is underneath. He went through the painstaking process of installing a slew of new drivers and tweaking some code within select .inf files, and in the end he seemingly found a way to get Optimus drivers working on the new rig. Of course, the debate has been raging on for five pages now, and it still seems inconclusive as to what's really going on behind the scenes. In related news, ZoinksS2k seems to have discovered a way to get Windows 7's TRIM feature working on his SSD-equipped VAIO Z, and if you're interested in doing some tinkering of your own in either case, you know where to dive in. [Thanks, Bill]

Intel's X25-V and Kingston's SSDNow V Series face off in battle for best value SSD
Got $125 and a burning desire to get in on the SSD fun? Intel and Kingston both have models priced to seduce that cash away from your pocket, and here comes AnandTech with a comparative review to help you make an informed decision. To start off with, Intel's X25-V sports 40GB of storage and is described as a smaller version of the X25-M G2, whereas Kingston's V Series boot drive offers a smaller 30GB capacity but also comes with a fuller upgrade kit. Since this is 2010 and not some prehistoric age, both drives naturally come equipped with Trim support. In benchmark results, Intel's drive took the advantage in the performance of random read/write tasks, but was second best when it came to sequential write jobs. Ultimately, that extra 10GB of storage and the fact you're more likely to capitalize on random, rather than sequential, drive access swung it in favor of the X25-V. Hit up the full review for the more nuanced impressions.

Corsair Force gives us another SandForce-controlled SSD speed demon
Seriously, if you're shopping for an SSD and don't know the name SandForce yet, you're not doing it right. The producer of what looks to be the consensus fastest controller on the market is spreading its wings today with a new drive announced by Corsair that offers its SF-1200 chip and capacities of either 100GB or 200GB. The Force follows swiftly in the wake of the Nova and Reactor series and represents Corsair's new flagship device in this space. It'll offer the generous consumer a sweet 280MBps read and 260MBps write speeds (yes, those are megabytes we're talking about), "class-leading random read/write performance," and the requisite Trim support to ensure it maintains that performance in the long run. A specific price is not yet known, but these are expected out within the next couple of weeks.

SanDisk ships 60GB / 120GB G3 SSD to North America and Europe
Lookin' to get your flash on, are you? Fret not, as SanDisk has just announced that its 60GB and 120GB G3 solid state drives are headed out to retailers as we speak. Both North America and Europe are getting served simultaneously, with the drives promising sequential performance of up to 220MB/sec on the read side and up to 120MB/sec on the write side. You'll also be thrilled to know that the G3 range supports the newest Windows 7 TRIM feature, which enables the drive to "continuously manage its resources and retain optimized performance throughout its lifespan." Those anxious to supplant their existing 2.5-inch HDD can snag one now from the web for $229.99 (60GB) / $399.99 (120GB), while those who prefer ye old B&M sales will have to wait a few weeks still.

Kingston's latest SSDNow V+ reviewed in 128GB flavor
Kingston's SSDNow V+ series is hitting the streets, and bit-tech.net has put it, and its new Toshiba controller, through the wringer. That new silicon offers TRIM support in Windows 7, intended to remove any lingering fears of performance degradation, and this drive has been graced with 128MB of internal cache to conquer random read and write performance. In general the review finds that the controller does its job and TRIM'd deletes don't have a major affect on performance, but there still was some degradation after 1TB worth of writes and deletes. Beyond that the included cache didn't seem to help random I/O performance, and in general the drive doesn't exactly dominate the benchmarks. So, if you've recently upgraded to something else and were feeling a bit of buyers' remorse, you're safe -- for now.

Windows 7 gets a thorough SSD optimization guide
We all know we want an SSD, but do we truly know what to do with one when we get it? Sure, you could plug it into the familiar SATA and power cables and consider your job done, but that's not really the way of the geek. To educate us wistful, hopeful, soon-to-be SSD owners, TweakTown have put together a comprehensive guide on optimizing your solid state storage -- starting from the very first step of picking out the right drive. What lies ahead is a full breakdown of the controllers available on the market today, along with helpful reminders of the importance of Trim command and garbage collection support. After you pick out your perfect life partner, you'll be wanting to ensure it plays along nicely with Windows 7 as well, and they've got you covered on that front too. Just hit the source link and get informed. We did, even though we still can't afford to buy one of these mythical drives.

Kingston's SSDNow V+ series hits 512GB capacity, adds Trim support
Kingston's upping the ante on its solid state drive series in pretty much all the ways that count. The SSDNow V+ line boasts a 512GB upper limit, twice the previous generation, with iterative options for 256GB, 128GB, and 64GB. Read / write speeds have more than doubled to 230MB/sec and 180MB/sec, respectively. Best of all, these suckers now support TRIM. Prices range from as low as $268 for standalone 64GB an can go as high as $1968 for 512GB, with an extra $15 or so tacked on if you want the bundle instead -- still alluring, still not for the feint of funding, but the good news is, if you don't need Trim or the extra speed, the original SSDNow V series is available for much smaller dents on your wallet.

Intel SSD firmware 02HD brings back Trim support, sans bugs
Intel's 34nm X25-M G2 drives might not've had the most peaceful of existences so far, but you can't fault the company's efforts to fix whatever maladies have popped up. The latest firmware update from Santa Clara brings back the lauded Trim support, but this time leaves the drive-killing antics behind. User experiences so far have been positive, though unsurprisingly a couple of people have questioned whether Trim is in fact enabled on their drives -- clearly, the difference between fast and really, really fast is not as distinguishable as we like to think. The source link will provide you with the latest firmware update tool and the precious new code -- if you dare risk it. [Thanks, Alex]

OCZ's Colossus desktop SSD gets reviewed: oh yeah, it's fast
It's been a long time coming, hasn't it? OCZ Technology's Colossus is the outfit's first in the desktop SSD space, and with capacities scaling as high at 1TB, it's certainly tempting for performance junkies who just can't pry themselves away from their tower. The benchmark-minded kids over at PC Perspective were able to get a drive in with final firmware a few weeks back, and they've pushed out a full review just prior to these things hitting retail en masse. Needless to say, all the numbers in the world won't make this any cheaper, but for those willing to spend at least $3.24 per gigabyte on internal storage, there's hardly a better option out right now. Reviewers found that read and write speeds seriously pushed the SATA 3Gb/sec limit, and the latter were "faster than on any SATA device tested to date." Sadly, the lack of TRIM support and the inability for end-users to upgrade the firmware put somewhat of a damper on things, but if neither one of those tidbits bother you, pulling the trigger just might be the right thing to do.
