Samsung recently announced volume production of a new lineup of SSDs using the fast SATA 3 (6Gb/s) interface and will be available in 128GB, 256GB, and 512GB capacities.  The new SSDs are called the PM830 series, and Samsung expects the drives to replace their SATA 2 (3Gb/s) drives by year-end.

Wanhoon Hong, executive vice president, memory sales & marketing, Device Solutions, Samsung Electronics stated that Samsung's new SSDs "will raise the performance bar to the next level for ultra-slim notebooks and tablets."  In addition, he believes that the new high capacity drives will spur competition in that segment and increase market interest in SSDs with greater-than 256GB capacities.

The new PM830 drives use Samsung's 20nm class (their term for a process node somewhere between 20 and 29), 32 Gigabit MLC NAND flash with a toggle DDR interface in addition to a proprietary controller.  Samsung claims that the controller and flash are able to take advantage of the SATA 6Gb/s interface by delivering 500MB/s sequential read speeds and 350MB/s sequential write speeds.  Further, the drive uses AES 256-bit encryption to secure private and corporate data.

The new SATA 6Gb/s solid state drives are targeted at OEMs for use in notebooks and tablets.  They are currently only available to OEMs; however, a consumer variant of the drive is forthcoming and will be announced at a later date.

Hitachi recently released a new enterprise class SSD based on Intel's 25nm MLC flash.  Dubbed the Hitachi SSD400M, the new solid state drive is aimed at Enterprise users and Cloud data centers.  It comes in the standard 2.5" form factor, features a SAS 6Gb/s interface, and will be available in 200GB and 400GB capacities.

As an enterprise drive, the Hitachi SSD400M supports end to end data protection, error correction, error handling and self encryption on certain models compliant with the Trusted Computing Group’s Enterprise A Security Subsystem Class encryption specification.  Further showing it's intended usage as an Enterprise drive, the 25nm MLC based drive is rated for 7.3 Petabyte lifetime write, which Hitachi says amounts to 10 full drive writes per day for five years.  Coincidentally, the warranty of the drive is a five year limited warranty or until the drive exceeds the maximum rated number of petabyte writes per capacity.  Hitachi states that they expect a .44 annual failure rate and have projected a 2 million hour MTBF.

Performance of the drive is much better than that of the previously reported Intel drive, as it delivers 495MB/s sequential reads and 385MB/s sequential writes.  The SSD is further rated at 56,000 read IOPS and 24,000 write IOPS.

The SSD400M has already shipped to various OEMs and will be available soon.  More information on the new SSD can be found here.

Intel 710 SSD Prices Leaked

According to VR-Zone, Intel's newest enterprise series 710 Lyndonville solid state drives (SSD) will be launching soon in a mid-august time frame, and will be carrying a price-per-gigabyte metric that only a corporate expense account could love.

The Intel 311.  The 710 series will have the same 2.5" form factor.

The new drives will come in 100GB, 200GB, and 300GB capacities and will be priced at approximately $650, $1250, and $1900 USD respectively.  Featuring 25mm eMLC HET, the drives feature 64MB of cache, user-controllable over-provisioning up to 20% (which helps drive longevity by reserving more of the drive for replacement of worn out cells), and a SATA II 3.0Gbps connection.  The SATA 3Gbps connection is not likely to bottleneck the drive as it will only feature 270MB/s read and 210MB/s write speeds.

The eMLC HET flash chips are higher quality MLC chips that Intel hopes will provide enterprise level SLC enduring without the higher cost of the SLC chips.  Interestingly, the drives only carry a 3 year warranty that is then further impacted by the state of the E9 wear level indicator so that the warranty expires once the three years are up or the E9 indicator reaches 1, whichever comes first.  The consumer grade Intel 320 drives on the other hand carry a longer 5 year warranty.

My aging X-25 drive remembers the days when Intel pushed for driving down the cost of SSDs; however, does Intel still remember that goal?

For a few dollars more; synchronized SSD shooters draw first

Subject: Storage | August 8, 2011 - 02:10 PM |
Tagged: ssd, sata 6Gps, asynchronous flash, synchronous flash, SF-2281 controller

With the latest SSD controller from SandForce, the SF-2281 SATA III, we have been seeing two different types of flash memory used as the storage medium depending on which vendor or product line you look at.  Asynchronous flash and synchronous flash differ in their timing when sending read and write commands, [H]ard|OCP's analogy of synchronous flash working like DDR is perfect as the new variety can send a command on both the rise and the fall of a clock cycle.

The reason this now matters is SATA III, which allows enough bandwidth for synchronous flash to show off its higher speeds; with the previous SATA standard it simply had no impact.  That speed impact on the new standard becomes obvious in [H]'s testing, especially when they fill both drives half way and conduct some real world tests.  Now that some of both types of drives are on the market, they also look at the price difference between the two types of flash,; a comparison in which the old asynchronous flash does not look good coming out of.

Patriot tries out the SandForce 2281 controller in the newest Wildfire SSD

Subject: Storage | August 1, 2011 - 03:51 PM |
Tagged: ssd, patriot, wildfire 120GB, sandforce, SF-2281 controller

120GB is a nice spot for SSDs, enough space for an OS and limited programs but without forcing you to spend $500+.  The Patriot Wildfire 120GB SSD SATA 6GB/s drive is $300, not the least expensive but certainly competitive with other similar drives, in price.  As for performance, with the new SATA standard and a SandForce controller it seemed best matched against the OCZ Vertex III Max IOPS.  Hi Tech Legion's testing showed the two to be running neck and neck in both performance and price.  Competition that close will hopefully bring sales and discounts making both drives even more attractive.

"The Patriot Wildfire 120GB SSD claims to deliver enterprise-class performance on a home PC. The Patriot Wildfire 120GB SSD is equipped with the SandForce SF-2281 controller paired with 16 8GB Toshiba 32nm toggle mode NAND chips. Much like other next generation SandForce based SSDs, the Patriot Wildfire 120GB has DuraWrite technology, Windows 7 TRIM support and is 256-bit AES encryption capable. With a sequential read speed of 555MB/s and write speed of 520MB/s, as well as a max random write IOPS of 85,000, the Patriot Wildfire 120GB SSD is aimed squarely at enthusiasts who want raw speed and uncompromised performance."

SanDisk joins the hard drive haters with the release of their Ultra SSDs

Subject: General Tech | July 28, 2011 - 12:40 PM |
Tagged: ssd, sandisk, sandisk ultra

SanDisk is releasing a line of SSDs, called the Ultra series.  They are not aimed at the high end market, they use the older SATA 2 interface and claim sequential transfer speeds of 280MB/s read and 270MB/s write.  The prices should range from $130 for the 60GB product to $450 for the 240GB model, which puts them about middle of the road for pricing.  They also list expected lifetime in terms of the amount of data written to them; 40TB of data written for the 60GB up to 120TB of total data written to the 240GB.  The Register covered the release here.

Elreg_sandisk_ultra_ssd.jpg

"SanDisk has a new Ultra line, a cruise flash missile aimed at taking out PC and notebook hard drives and replacing them with much faster SanDisk SSDs.

These are 2.5-inch format, 2-bit multi-level cell flash drives, coming in 60, 120 and 240GB capacity points. The Ultra brand is used by SanDisk for consumer flash products such as SDHC cards, and now a trio of SSDs will be sold under the Ultra name."

OCZ wraps both its ARMs around a new SSD controller and gives it a little TLC

Subject: General Tech | July 26, 2011 - 12:03 PM |
Tagged: ssd, ocz, arm, tlc, sata 6Gps, Indilinx Everest

OCZ is never satisfied with the performance of their SSDs in general and their controllers specifically.  After purchasing Indilinx to ensure that their controllers would be of high quality and designed to OCZ's specific needs, they've now been pushing Indilinx to improve on their controllers.  That has lead to Everest, which has a dual core ARM processor and 400MHz DDR3 cache that can support up to 512MB.  The controller is optimized for 8K writes which is perfect for the current flash utilized in SSDs.  OCZ has also optimized the flash memory, developing Triple Level Cell (TLC) which has three layers as opposed to MLC which sports two.  The controller will be backwards compatible, which is a good idea if OCZ wants to license the controller to other manufacturers, which makes sense as Everest should hit 200MT/s as compared to SandForce's current 166MT/s.  There is more that this controller can do, click on over to The Register to read about it.

"OCZ is sampling a new flash controller that gives a picture of future solid state drives.

The company bought Indilinx for its solid state drive (SSD) controller technology in March this year and has now unveiled the Indilinx Everest controller platform.

It has a 6Gbit/s SATA III interface, a dual-core ARM processor and a number of enticing features, such as 3-bit multi-level cell (MLC) support. This is going to be called TLC, for triple-level cell, to distinguish it from today's MLC, which is 2-bit MLC."

Corsair Forces synchronicity into their latest SSD

Subject: Storage | July 25, 2011 - 05:15 PM |
Tagged: ssd, corsair, corsair force gt 120GB, sata 6Gps

The new Corsair Force GT 120GB SSD goes a different way from the crowd with their use of synchronous MLC flash memory, the SF-2000 controller is very familiar though.  Synchronous flash is more expensive than asynchronous and in theory should provide better speeds with large uncompressed files, though not a huge boost. That theory bore out Neoseeker's testing with better results across the board when compared to the Patriot Wildfire SSD.  If you are willing to invest the money to get that little bit more out of your machine, the Corsair Force is worth considering.

NS_Force GT 4.jpg

"In an SSD market where 500MB/s data read/write speeds are becoming the norm across manufacturers, Corsair's Force GT differentiates itself from the pack by using 25nm ONFI synchronous NAND flash memory, versus standard 25nm asynchronous NAND. This allows the drive to excel at reading and writing compressed data, which is supposed to translate into faster real-world performance with files like video, music and graphics. Hit our latest SSD review to see just how real this real-world performance ends up looking."

Intel reproduces '8MB bug', fix coming soon.

Subject: Storage | July 24, 2011 - 09:22 PM |
Tagged: ssd, Intel, firmware, 320

We've seen some recent mumblings about a corner case where inadvertent or improper power loss to an Intel 320 Series SSD would result in the drive getting stuch in an inaccessible mode where it appears as an 8MB drive. From what I've gathered, the issue seems rare and may be tied to some specific hardware configurations.

The SSD 320 we tested back in March (we couldn't get it to 'stick' in 8MB mode).
