A colleague pointed The SSD Guy to an ExtremeTech article about researchers at Japan’s Chuo University who have designed an SSD that uses a resistive RAM (ReRAM) as a buffer and is built using TSV technology. The design was presented at the IEEE’s 2012 Symposium on VLSI Circuits this month in Hawaii. A Nikkei article gives additional information.
The basic architecture reminds me of an FRAM + NAND SSD design that a Korean university presented at the Flash Memory Summit a few years ago. Either approach gets past the problem of using a failure-prone battery, a temperature-sensitive supercap, or a big bulky bank of Continue reading
SanDisk today announced the acquisition of Schooner Information Technology, a developer of SSD-optimized software. Terms were not announced.
This is a good move for SanDisk and a good move for Schooner. SanDisk’s enterprise strategy is suddenly coming into focus.
Schooner has had an interesting and difficult history. The company started out as a manufacturer of appliances based on standard computer hardware, one that ran MySQL, and the other Continue reading
SMART Storage Systems has introduced a new enterprise-class SSD that the company says: “increases the endurance of cMLC Flash to a level that makes SLC drives obsolete.” That’s a pretty hefty claim!
The new Optimus Ultra+ SSD is specified at 100K read IOPS and 60K write IOPS, through its 6Gb/s SAS interface. With capacities ranging from 100-800GB, this SSD supports up to 50 full drive writes per day over its 5-year lifespan, double that of the company’s Optimus Ultra which was introduced in February. That’s quite something for an MLC-based SSD.
SMART has tapped into its Guardian technology to reap SLC benefits from MLC flash through both enhanced external and internal algorithms. Like all other SSD makers and SSD controller makers SMART has focused a lot of attention on error correction, DSP, and other means of correcting errors externally to the flash. The company has also partnered with Continue reading
According to the press release Seagate will use DensBits’ technology for “consumer and enterprise applications including 3 bits/cell (“TLC”) 1Xnm Flash-based consumer-grade SSD, and 2 bits/cell (“MLC”) 1Xnm Flash-based enterprise-grade SSD.”
