LSI Corp. has launched a new blog that covers (among other things) flash storage. It’s only natural – the company’s SandForce subsidiary is riding high on the SSD wave and LSI’s HBAs are finding widespread use, both internally and externally, in the production of two-hop PCIe SSDs.
Intel has gotten into the fast-growing and lucrative market for PCIe SSDs. The company has announced a PCIe SSD, the 910, that provides the high performance you would expect of a PCIe drive with the quality guarantees that customers expect of Intel.
Who could blame them? Fusion-io has become a Wall Street darling for creating the PCIe SSD market, and still rides it to continually growing revenues. LSI is fascinated by the growth of its Warp Drive. Micron attained a significant design win at EMC, Texas Memory Systems (TMS) has had success in its own narrow markets, and Virident, OCZ, and STEC have also participated in the PCIe SSD’s market growth.
Intel’s 910 consists of four Hitachi SAS SSD Continue reading
On April 3 & 4 Avnet Embedded will host an on-line conference called the SSD Virtual Summit. This free on-demand seminar will feature a keynote by Yours Truly, The SSD Guy, and presentations by leading SSD makers and related firms including Adaptech, Crucial, Dell, HGST, Intel, Kingston, LSI, Micron, OCZ, Rorke Data, Seagate, SMART Storage, STEC, and Toshiba.
Come join in to learn the latest information on SSDs.
Today Hitachi announced the company’s second generation Ultrastar SSD400S.B family, which Hitachi claims to be the industry’s first 25nm SLC enterprise-class SSD family.
The new Hitachi SSDs support a SAS 6Gb/s dual port interface. SLC NAND flash was chosen for its high write performance and endurance.
Maximum sequential read speeds of 536MB/s and a sequential write speed of up to 520MB/s with 57K random read IOPS and 25K random write IOPS help to give ultra-fast access to data.
Intel has announced a new SSD for the Enthusiast/Gamer market. Intel’s fastest drive to date, this SSD, formerly known as “Cherryville” but now called the 520, is the first Intel SSD to use a SandForce/LSI controller and is made using Intel’s own 25nm flash.
Intel worked with SandForce for a year and a half to produce an SSD that met Intel’s rigorous standards, and made hundreds of changes to SandForce’s firmware. Users of SandForce controllers can differentiate their SSDs through the addition of features in the SSD controller’s firmware. Intel did this by tapping into its expertise in end-to-end data protection (something the company learned when working with Hitachi to introduce that company’s Intel-based enterprise SSDs) while harnessing Intel’s deep understanding of its own NAND flash and of the I/O needs of the PC.
End-to-end data protection is not a trivial feature: Continue reading
One of the SSD Guy’s favorite subjects is caching and SSDs. This is because I wrote a book on processor caches in the early 1990s, and the advent of SSD caches in storage systems hearkens back to the technology detailed in that book.
Caching works well whenever there are two layers in the memory hierarchy since the fast expensive layer can replicate data in the slow inexpensive layer to accelerate the processor’s performance. Continue reading
On October 26 LSI announced its acquisition of leading SSD controller maker SandForce. The privately-held firm has made significant strides in the development of high-performance controllers that have gained great popularity through a string of impressive benchmark results in the online reviewer community.
