Toshiba Corp. on Wednesday unveiled its new family of solid-state drives (SSDs) intended for enterprise applications. The drives are based on single-level cell (SLC) memory and boast massive performance and rock-solid reliability. The drives are based on Toshiba’s own controllers and hence will be vastly different than solutions offered by competitors.

Available in capacities of 100GB, 200GB, and 400GB, the MKx001GRZB family of SSDs deliver random sustained 90 000 read and 17 000 write IOPS [input output operations per second] and sequential sustained 510MB/sec read and 230MB/sec write throughput. This realizes read speeds more than 3 times faster than for Toshiba's current enterprise HDD, according to the company. The drives require 6.5W for operation, which is higher compared to SSDs by some other companies, but thanks to high I/O performance Toshiba declares “industry-leading power efficiency rating” of 13 800IOPS/watt. The SSDs come in 2.5” form-factor and with Serial Attaches SCSI interface.

The enterprise-grade SSD drives from Toshiba are based on single-level cell NAND flash memory from Toshiba, and are the industry first 32nm SLC-based drives for enterprises. Toshiba claims that controllers for the MKx001GRZB solid-state drives feature “know-how in controller and firmware design for enterprise HDDs”.

Samples of the new SSDs will be available for customer qualification in the first quarter of 2011.

As the IT world makes the transition to cloud solutions, data that are now stored in individual users devices – desktop and portable PCs and tablet PCs – will increasingly be stored in server farms. The enterprise storage systems required for this are optimized in terms of overall performance, power and cost by structuring high performance devices with different capacities in layers.

The Toshiba enterprise SSD lineup forms the pinnacle of a tiered storage architecture that enables organizations to effectively tune the performance, capacity, endurance, and reliability of their storage environments.  For data storage that requires high reliability and high capacity – but not the very rapid access to data provided by SSDs – Toshiba has also released the new MK x001TRKB and MKx002TSKB series hard disk drives (HDDs), the former with an SAS interface, the latter a SATA interface.
