Centon Electronics today announced an expansion of their solid state drive lineup with new SATA III offerings. The 2.5” SATA III drives utilize 20nm class MLC (multi level cell) flash memory and a SandForce 2281 SSD controller. They claim that the drives will take full advantage of the extra bandwidth provided by SATA III with read and write speeds of 400 MB per second and 300 MB per second respectively.
According to a chart on Centon’s website, the new SATA III SSDs are part of a new VVS1 series and they come in 60 GB (though this is listed as VS1 series), 120 GB, and 240 GB capacities. The drives support RAID and are rated for a mean time before failure (MTBF) of 2 million+ hours. They further carry a two year warranty. The 240 GB and 120 GB SATA III SSDs are rated at the 400 MB/s and 300 MB/s read and write speeds, but the 60 GB SATA III SSD is only rated at a max of 300 MB/s read and 200 MB/s write. More information can be found on the company's website.Currently, there is no word on pricing or availability. Also, don't forget about our SSD Decoder for all your SSD research!
Samsung today announced a new lineup of consumer solid state drives (SSD) with the SATA 3 (6Gb/s) interface called the SSD 830 Series. We reported last week on this series of SSD's OEM variant, the PM830 Series, and this week is the unveiling of the consumer versions.
The new 830 SSD series builds on its Samsung 470 predecessors while upgrading the controller interface to SATA 3 (6Gb/s), providing twice the amount of available bandwidth. Further, the consumer drives differentiate themselves from the PM830 OEM versions in three distinct manners, including capacity sizes, exterior design, and bundled components.
On the aesthetic front, the 830 drives have a dark brushed aluminum body with a silver colored Samsung logo and orange corner accent, while the OEM PM830 drives are more simple in design with a dark casing and information sticker.
Further proving that the drives are meant for consumer usage, Samsung provides a full upgrade bundle that (in addition to the SSD itself) includes a copy of Norton Ghost to image an old drive onto the new SSD, a 2.5" to 3.5" adapter bracket, all the necessary cables, and detailed instructions on how to use the drive. A notebook oriented upgrade bundle will also be available that includes the SSD itself, manuals, Norton Ghost software, and a USB to SATA adapter to image the old drive onto the new SSD before switching the new drive into the laptop.
The full upgrade kit for desktops.
The new 830 SSD lineup will come in consumer friendly capacities of 64GB, 128GB, 256GB, and 512GB (for comparison, the OEM PM830 versions only come in capacities greater than 128GB).
Unfortunately, Samsung has not yet announced pricing or detailed specifications on the new drives, instead opting to withhold that information until the official product launch in October 2011. If the OEM versions are any indication on the speed front; however, the consumer versions are looking at MLC NAND capable of respectable 500MB/s read and 350MB/s write speeds.
Update 8/25/2011: We recently came across a few more tidbits of information on the Samsung 830 consumer SSDs. Specifically, the drives will be powered by a triple ARM9 based controller that is similar to their previous generations. The NAND flash that the drives will use is 20nm class rated, which is marketing speak for any NAND manufacturing node that is between 20nm and 29nm. In Samsungs case, they are likely utilizing 25nm MLC NAND for their 830 series drives. Finally, the company will be releasing their own "software toolbox" to keep the SSDs healthy by performing secure erase, monitoring, and user adjustible over-provisioning. Over-provisioning is a process that reserves a specificied amount of NAND cells so that the SSD controller can replace bad and/or worn out cells and keep performance and capacity at stable levels.
End of Update.
Stay tuned to PC Perspective for more information on the new drives as we get closer to the official launch 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.
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?
Samsung recently began production on new 20nm MLC NAND flash memory chips with densities of 64Gb (Gigabit) and a toggle DDR 2.0 interface. The chips are not only twice as dense as their previous NAND chips, but Samsung also claims that they are capable of 400Mbps of bandwidth.
This 400Mbps bandwidth is thanks to a new toggle DDR 2.0 interface, which purports to bring a three times performance increase over the 133Mbps of bandwidth provided by the older toggle DDR1 interface with 32Gb NAND chips. Samsung further states that the new 64Gb MLC NAND chip offers close to a 50% increase in productivity versus 20nm 32Gb MLC NAND with a toggle DDR 1.o interface that Samsung began producing in April 2010.
The press release also states that:
"According to IHS iSuppli, the worldwide NAND flash memory market will continue to steadily grow from approximately 11 billion 1 Gigabyte (GB) equivalent unitsin 2010 to 94 billion 1GB equivalent units in 2015 with a CAGR of 54 percent. In addition, shipments of NAND flash memory with 64Gb or higher density are expected to account for approximately 70 percent of total NAND flash memory shipments in 2012, a huge increase from the three percent level in 2010."
The NAND flash market is certainly seeing rapid growth and technological progression, with the proliferation of SSDs from Intel, OCZ, Crucial, and others. As densities of flash memory get higher and manufacturing nodes get smaller, cheaper and more spacious storage will make it's way to both future mobile devices and solid state drives, which is good news for both consumers and Samsung.

A while back, Intel and Micron jointly announced the beginnings of 20nm flash memory production, promising a 50% increase in die count per wafer (or a 50% reduction in per die production cost, depending on how you slice it). This shrink only did just that - shrink the die. Capacity remained at 64Gbit (8GB).
A few days ago IMFT also announced another way to shrink that die, but this time keeping with the now 'old' 25nm process. It turns out they have refined 25nm to the point where consumer-grade TLC flash can be produced. TLC is Triple-Level-Cell. While SLC (Single) holds 1 bit per cell, and MLC (Multi) holds two, TLC holds 3 bits per cell. Compared to the MLC 25nm dies, this gives a capacity increase without changing much else. IMFT, however, is happy with the 8GB 'sweet spot', so instead of jumping to a 12GB die of the same physical size, they are opting to instead shrink the current 25nm die to 131mm^2.
25nm TLC die, same 8GB capacity, but less area than the 25nm MLC die.
This gives Intel and Micron two options for ultimately reducing the price of flash - either by shrinking the process and getting more 8GB MLC dies out of a 20nm wafer, or by squeezing more bits into each cell of existing 25nm flash.
This is good stuff. Let's hope it gets even more SSD's into even more machines this holiday season.
