MojoKid writes Samsung just took the wraps off a new family of mainstream solid state drives, targeting the market segment previously occupied by its popular SSD 840 EVO series. The new Samsung SSD 850 EVO series is the follow-up to the company's current flagship SSD 850 PRO, but the new EVO is Samsung's first to pack 32layer 3D VNAND 3-bit MLC flash memory. The move to 32layer 3D VNAND 3-bit MLC flash brings pricing down to the .50 to .60 per GiB range, but doesn't adversely affect endurance because the cell structure doesn't suffer from the same inherent limitations of planar NAND, since the cells are stacked vertically with the 3D VNAND. The new 850 EVO drive performs well with large sequential transfers and also offered very low access times. The compressibility of the data being transferred across the Samsung SSD 850 EVO had no impact on performance and small file transfers at high queue depth were fast. Small file transfers with low queues depths, which is what you'd expect to see with most client workloads, were also very good. The Samsung SSD 850 EVO drives also put up excellent numbers in trace-based tests like PCMark 7.

crookedvulture writes The SSD Endurance Experiment previously covered on Slashdot has reached another big milestone: two freaking petabytes of writes. That's an astounding total for consumer-grade drives rated to survive no more than a few hundred terabytes. Only two of the initial six subjects made it to 2PB. The Kingston HyperX 3K, Intel 335 Series, and Samsung 840 Series expired on the road to 1PB, while the Corsair Neutron GTX faltered at 1.2PB. The Samsung 840 Pro continues despite logging thousands of reallocated sectors. It has remained completely error-free throughout the experiment, unlike a second HyperX, which has suffered a couple of uncorrectable errors. The second HyperX is mostly intact otherwise, though its built-in compression tech has reduced the 2PB of host writes to just 1.4PB of flash writes. Even accounting for compression, the flash in the second HyperX has proven to be far more robust than in the first. That difference highlights the impact normal manufacturing variances can have on flash wear. It also illustrates why the experiment's sample size is too small to draw definitive conclusions about the durability of specific models. However, the fact that all the drives far exceeded their endurance specifications bodes well for the endurance of consumer-grade SSDs in general.

itwbennett writes: For too long, it looked like SSD capacity would always lag well behind hard disk drives, which were pushing into the 6TB and 8TB territory while SSDs were primarily 256GB to 512GB. That seems to be ending. In September, Samsung announced a 3.2TB SSD drive. And during an investor webcast last week, Intel announced it will begin offering 3D NAND drives in the second half of next year as part of its joint flash venture with Micron. Meanwhile, hard drive technology has hit the wall in many ways. They can't really spin the drives faster than 7,200 RPM without increasing heat and the rate of failure. All hard drives have now is the capacity argument; speed is all gone. Oh, and price. We'll have to wait and see on that.

MojoKid (1002251) writes One of the disadvantages to buying an Apple system is that it generally means less upgrade flexibility than a system from a traditional PC OEM. Over the last few years, Apple has introduced features and adopted standards that made using third-party hardware progressively more difficult. Now, with OS X 10.10 Yosemite, the company has taken another step down the path towards total vendor lock-in and effectively disabled support for third-party SSDs. We say "effectively" because while third-party SSDs will still work, they'll no longer perform the TRIM garbage collection command. Being able to perform TRIM and clean the SSD when it's sitting idle is vital to keeping the drive at maximum performance. Without it, an SSD's real world performance will steadily degrade over time. What Apple did with OS X 10.10 is introduce KEXT (Kernel EXTension) driver signing. KEXT signing means that at boot, the OS checks to ensure that all drivers are approved and enabled by Apple. It's conceptually similar to the device driver checks that Windows performs at boot. However, with OS X, if a third-party SSD is detected, the OS will detect that a non-approved SSD is in use, and Yosemite will refuse to load the appropriate TRIM-enabled driver.

Lucas123 writes: Samsung has issued a firmware fix for a bug on its popular 840 EVO triple-level cell SSD. The bug apparently slows read performance tremendously for any data more than a month old that has not been moved around on the NAND. Samsung said in a statement that the read problems occurred on its 2.5-in 840 EVO SSDs and 840 EVO mSATA drives because of an error in the flash management software algorithm. Some users on technical blog sites, such as Overclock.net, say the problem extends beyond the EVO line. They also questioned whether the firmware upgrade was a true fix or if it just covers up the bug by moving data around the SSD.

Lucas123 writes: Micron's newest client flash drive line, the M600, uses its first 16nm process technology and dynamic write acceleration firmware that allows the flash to be programmed as SLC or MLC instead of using overprovisioning or reserving a permanent pool of flash cache to accelerate writes. The ability to dynamically program the flash reduces power use and improves write performance as much as 2.8 times over models without the feature, according to Jon Tanguy, Micron's senior technical marketing engineer. The new lithography process technology also allowed Micron to reduce the price of the flash drive to 45 cents a gigabyte.

MojoKid (1002251) writes AMD is launching a new family of products today, but unless you follow the rumor mill closely, it's probably not something you'd expect. It's not a new CPU, APU, or GPU. Today, AMD is launching its first line of solid state drives (SSDs), targeted squarely at AMD enthusiasts. AMD is calling the new family of drives, the Radeon R7 Series SSD, similar to its popular mid-range line of graphics cards. The new Radeon R7 Series SSDs feature OCZ and Toshiba technology, but with a proprietary firmware geared towards write performance and high endurance. Open up one of AMD's new SSDs and you'll see OCZ's Indilinx Barefoot 3 M00 controller on board—the same controller used in the OCZ Vector 150, though it is clocked higher in these drives. That controller is paired to A19nm Toshiba MLC (Multi-Level Cell) NAND flash memory and a DDR3-1333MHz DRAM cache. The 120GB and 240GB drives sport 512MB of cache memory, while the 480GB model will be outfitted with 1GB. Interestingly enough, AMD Radeon R7 Series SSDs are some of the all-around, highest-performing SATA SSDs tested to date. IOPS performance is among the best seen in a consumer-class SSD, write throughput and access times are highly-competitive across the board, and the drive offered consistent performance regardless of the data type being transferred. Read performance is also strong, though not quite as stand-out as write performance.

MojoKid (1002251) writes Though solid state drives have a long way to go before they break price parity with hard drives (and may never make it, at least with the current technology), the gap continues to close. More recently, SSD manufacturers have been approaching 50 cents per GiB of storage. OCZ Storage Solutions, with the help of their parent company Toshiba's 19nm MLC NAND, just launched their ARC 100 family of drives that are priced at exactly .5 per GiB at launch and it's possible street prices will drift lower down the road. The ARC 100 features the very same OCZ Barefoot 3 M10 controller as the higher-end OCZ Vertex 460, but these new drives feature more affordable Toshiba A19nm (Advanced 19 nanometer) NAND flash memory. The ARC 100 also ships without any sort of accessory bundle, to keep costs down. Performance-wise, OCZ's new ARC 100 240GB solid state drive didn't lead the pack in any particular category, but the drive did offer consistently competitive performance throughout testing. Large sequential transfers, small file transfers at high queue depths, and low access times were the ARC 100's strong suits, as well as its low cost. These new drives are rated at 20GB/day write endurance and carry a 3-year warranty.

Lucas123 writes An AMD website in China has leaked information about the upcoming release of a line of SSDs aimed at gamers and professionals that will offer top sequential read/write speeds of 550MB/s and 530MB/s, respectively. AMD confirmed the upcoming news, but no pricing was available yet. The SSDs will come in 120GB, 240GB and 480GB capacities and will use Toshiba's 19-nanometer flash lithography technology. According to IHS, AMD is likely entering the gaming SSD market because desktop SSD shipments are expected to experience a 39% CAGR between now and 2018.

MojoKid writes: Intel just launched their new SSD 2500 Pro series solid state drive, the follow-up to last year's SSD 1500 Pro series, which targets corporate and small-business clients. The drive shares much of its DNA with some of Intel's consumer-class drives, but the Pro series cranks things up a few notches with support for advanced security and management features, low power states, and an extended management toolset. In terms of performance, the Intel SSD 2500 Pro isn't class-leading in light of many enthusiast-class drives but it's no slouch either. Intel differentiates the 2500 Pro series by adding support for vPro remote-management and hardware-based self-encryption. The 2500 Pro series supports TCG (Trusted Computing Group) Opal 2.0 features and is Microsoft eDrive capable as well. Intel also offers an administration tool for easy management of the drive. With the Intel administration tool, users can reset the PSID (physical presence security ID), though the contents of the drive will be wiped. Sequential reads are rated at up to 540MB/s, sequential writes at up to 480MB/s, with 45K – 80K random read / write IOps.

KDE Community (3396057) writes "KDE proudly announces the immediate availability of Plasma 5.0, providing a visually updated core desktop experience that is easy to use and familiar to the user. Plasma 5.0 introduces a new major version of KDE's workspace offering. The new Breeze artwork concept introduces cleaner visuals and improved readability. Central work-flows have been streamlined, while well-known overarching interaction patterns are left intact. Plasma 5.0 improves support for high-DPI displays and ships a converged shell, able to switch between user experiences for different target devices. Changes under the hood include the migration to a new, fully hardware-accelerated graphics stack centered around an OpenGL(ES) scenegraph. Plasma is built using Qt 5 and Frameworks 5." sfcrazy reviewed the new desktop experience. It would appear the semantic desktop search features finally work even if you don't have an 8-core machine with an SSD.

Vigile (99919) writes "As SSD controllers continue to evolve, so does the world of flash memory. With the release of the Samsung 850 Pro SSD announced today, Samsung is the first company to introduce 3D NAND technology to the consumer. By using 30nm process technology that might seem dated in some applications, Samsung has been reliably able to stack lithography and essentially "tunnel holes" in the silicon while coating the inside with the material necessary to hold a charge. The VNAND being used with the Samsung 850 Pro is now 32 layers deep, and though it lowers the total capacity per die, it allows Samsung to lower manufacturer costs with more usable die per wafer. This results in more sustainable and reliable performance as well as a longer life span, allowing Samsung to offer a 10 year warranty on the new drives. PC Perspective has a full review with performance results and usage over time that shows Samsung's innovation is leading the pack."

An anonymous reader writes Over the past few months, we've seen a disturbing trend from first Kingston, and now PNY. Manufacturers are launching SSDs with one hardware specification, and then quietly changing the hardware configuration after reviews have gone out. The impacts have been somewhat different, but in both cases, unhappy customers are loudly complaining that they've been cheated, tricked into paying for a drive they otherwise wouldn't have purchased.

crookedvulture (1866146) writes "Last year, we kicked off an SSD endurance experiment to see how much data could be written to six consumer drives. One petabyte later, half of them are still going. Their performance hasn't really suffered, either. The casualties slowed down a little toward the very end, and they died in different ways. The Intel 335 Series and Kingston HyperX 3K provided plenty of warning of their imminent demise, though both still ended up completely unresponsive at the very end. The Samsung 840 Series, which uses more fragile TLC NAND, perished unexpectedly. It also suffered a rash of cell failures and multiple bouts of uncorrectable errors during its life. While the sample size is far too small to draw any definitive conclusions, all six SSDs exceeded their rated lifespans by hundreds of terabytes. The fact that all of them wrote over 700TB is a testament to the endurance of modern SSDs."

MojoKid (1002251) writes "Crucial has been on a tear as of late. In the last few weeks alone, the company has released a couple of new series of solid state drives, one targeting the enthusiast segment (the M550) and the other targeting data centers (the M500DC). Today, Crucial is at it again with the launch of the brand new MX100 series. The Crucial MX100 series of solid state drives is somewhat similar to the M550 in that they both use the same Marvell controller. The MX100, however, is outfitted with more affordable 16nm NAND flash, and as such, the drives are priced aggressively at about .43 per GiB. However, these MX100 series of drives are still rated for 550MB/s sequential reads with 500MB/s (512GB), 330MB/s (256GB), or 150MB/s (128GB) and random read and write IOPS of 90K – 80K and 85K – 40K, respectively. The drives carry a 3-year warranty and are rated for 72TB total bytes written (TBW), which equates to 40GB written per day for 5 years. Performance-wise, these new lower cost SSDs, are on par with some of the fastest SSDs currently on the market but starting at $79.99 for the 128GB drive, they're relatively rather cheap."

mrspoonsi (2955715) writes "A breakthrough has been made in SSD technology that could mean drastic performance increases due to the overcoming of one of the major issues in the memory type. Currently, data cannot be directly overwritten onto the NAND chips used in the devices. Files must be written to a clean area of the drive whilst the old area is formatted. This eventually causes fragmented data and lowers the drive's life and performance over time. However, a Japanese team at Chuo University have finally overcome the issue that is as old as the technology itself. Officially unveiled at the 2014 IEEE International Memory Workshop in Taipei, the researchers have written a brand new middleware for the drives that controls how the data is written to and stored on the device. Their new version utilizes what they call a 'logical block address scrambler' which effectively prevents data being written to a new 'page' on the device unless it is absolutely required. Instead, it is placed in a block to be erased and consolidated in the next sweep. This means significantly less behind-the-scenes file copying that results in increased performance from idle."

MojoKid (1002251) writes "The PC market is changing rapidly as tablets supplant some laptops, new players such as the Chromebook disrupt the old WIntel model, and innovations in processors and graphics allow for ever-smaller PCs such as Intel's NUC (Next Unit of Computing) PC. Gigabyte recently introduced a rather unique product that combines the tiny 4.5-inch square form factor of Intel's NUC PC platform together with a mini DLP projector. The Gigabyte Brix Projector measures 4.24 x 4.5 x 1.93 inches (WxLxD) but manages to fit in an Intel Core i3-4010U (1.7GHz) processor with built-in Intel HD 4400 graphics and support for up to 16GB of 1600MHz RAM. Finally, an mSATA slot inside the chassis also supports up to a 256GB SSD. The system's DLP (LED backlight) projector itself offers a resolution of 864x480 with an aspect ratio of 16:9 and a purported image size of 7 to 85 inches. It promises 75 ANSI lumen brightness, a contrast ratio of around 900:1, and 3LED (RGB) technology. It's not an HD setup but the potential use cases are interesting. A follow-on version capable of 1080p output would be even more useful for gaming and HD video."

MojoKid (1002251) writes "OCZ was recently acquired by Toshiba and has been going through its product stack, revamping its SSD portfolio with fresh re-designs based on Toshiba NAND Flash memory for not only increased performance but better cost structure as well. OCZ has now replaced their RevoDrive family of PCIe SSD cards with an almost complete re-designed of the product. The RevoDrive 350 is based on the same OCZ VCA 2.0 (Virtualized Controller Architecture) technology as the previous generation but is now enabled with a PCI Express X8 card interface and up to 4 LSI SandForce SD-2282 SSD processors, along with 19nm Toshiba NAND Flash. The good news is, not only is the new RevoDrive 350 faster at 1.8GB/sec claimed bandwidth for sequential reads and 1.7GB/sec for sequential writes, but it's also significantly more affordable, at literally half the price of the previous gen RevoDrive 3 when it first launched. In the benchmarks, the new PCIe card excels at read throughput, regularly hitting its 1.8GB/sec claimed bandwidth, especially with sequential workloads. Write performance is solid as well and the drive competes with the likes of some higher-end and more expensive SLC NAND-based PCIe cards like LSI's WarpDrive and Intel's SSD 910."

As SSD density increases, reliability and performance decrease, creating a dilemma for manufacturers who must balance density, cost, reliability and performance. '[F]lash technology and SSDs cannot yet replace HDDs as primary storage for enterprise and HPC applications due to continued high prices for capacity, bandwidth and power, as well as issues with reliability that can only be addressed by increasing overall costs. At least for the foreseeable future, the cost of flash compared to hard drive storage is not going to change.'"
