Lucas Mearian has the speeds and feeds:

The drives claim some of the fastest serial-attached SCSI (SAS) connected drive speeds on the market. ... Maximum random sustained read rates of 90,000 input/output operations per second (IOPS) and 17,000 write IOPS ... maximum sequential sustained read rate of up to 510MB/sec. and 230MB/sec. for write.


The drives will be available in 100GB, 200GB and 400GB capacities and are being marketed ... as "Tier 0" offerings. ... Toshiba also stated that its new SSD family has low power requirements and uses only 6.5 watts during read/write operations. ... Toshiba didn't offer suggested pricing.

Chris Mellor compares with the competition:

The MKx001GRZB – Tosh doesn't go in for catchy brand names – is a 2.5-inch form factor and comes with the same ... capacity points as Hitachi GST's Ultrastar SSD announced in November. ... Tosh's SSD uses 32nm single level cell (SLC) process technology while the Hitachi GST SSD ... uses 34nm. ... They both have a 6Gbit/s SAS II interface.


What other enterprise-class 2.5-inch SSDs have such good performance numbers? ... It looks to [us] as if Hitachi GST and Toshiba share the ... high ground, with Toshiba scoring higher performance numbers. ... As Toshiba has an interest in Violin Memory, we can expect the flash storage array producer to use this Tosh SDD in the new year.

Jack Clark is Babel's cartographer:

The 200GB and 400GB have a guaranteed lifespan of five years with no limit on write operations. The 100GB drive ... has a limit on the total number of writes during that time — eight petabytes.

But when, Hubert Nguyen?

Expect samples to be available for customer qualification in Q1 2011, with volume production to begin in first half of next year.

Meanwhile, Brian Beeler spots related Toshiba news:

Toshiba also announced the MKx001TRKB and MKx002TSKB enterprise-series HDDs. The nearline models feature a capacity of up to 2TB in a traditional 3.5" form factor and offer 6Gb/s SAS and 3Gb/s SATA interfaces. ... [They] also include Error Correction (ECC), Rotational Vibration (RV) compensation technology for multi-drive systems, and enhanced power condition state technology.
