At the forefront of leading-edge manufacturing technology,

Toshiba offers enterprise-class solid state drives (SSDs) designed to support the market’s demand for higher performance, endurance, and lower power consumption in mission critical, enterprise applications.

The MKx001GRZB enterprise-class SSD represents the highest level of a tiered storage architecture that enables organizations to effectively tune the performance, capacity, and reliability of their storage environments. The

MKx001GRZB is offered in capacities of 100GB, 200GB, and 400GB 1 and designed for compatibility and ease of integration into new or existing tier-0 enterprise storage systems, including servers, direct-attached storage, and network-attached storage.

The new 2.5-inch small form factor drives utilize the latest

32 nanometer (nm) enterprise grade single-level cell (SLC)

NAND flash memory and 6Gb/s Serial Attached SCSI

(SAS) interface. The Toshiba SSD delivers performance that outpaces competing enterprise-class SSDs, with random sustained 90,000 read and 16,000 write IOPS 2 and sequential sustained 500MB/s read and 250MB/s write throughput.

Combined with a low power requirement of only 6.5 watts at operation, the Toshiba SSD also delivers an impressive power efficiency rating of 13,800 IOPS/watt.

One Gigabyte (1GB) means 10 9 = 1,000,000,000 bytes, one Terabyte (TB) means 10 12 =

1,000,000,000,000 bytes, and one Petabyte (1PB) means 10 15 = 1,000,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 2 30 = 1,073,741,824 bytes, 1TB = 2 40 = 1,099,511,627,776 bytes, and 1PB = 2 50 = 1,125,899,906,842,624 bytes, and therefore shows less storage capacity.

Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/ or pre-installed software applications, or media content. Actual formatted capacity may vary.
