SanDisk announces 4TB SSD

SanDisk this week announced the industry's first 4TB enterprise-class SAS solid-state drive (SSD) in its Optimus MAX product based on 19-nanometer eMLC NAND technology.

SanDisk's new 4TB Optimus MAX SAS SSD is the highest capacity 2.5-in. SSD drive to date. The SSDs come with a 6Gbps SAS interface. The Optimus MAX SAS SSD is capable of up to 400 MBps sequential reads and writes and up to 75,000 random I/Os per second (IOPS) for both reads and writes, the company said.

The Optmimus MAX can sustain between one and three full drive writes per day, meaning this equates to 3 write/day x 4TB x 5 year warranty x 365 = 21,900TB endurance.


SanDisk would not release pricing on the new SSDs because they will be sold mainly by partners. However, an October 2013 Gartner report placed the dollar per gigabyte cost for storage SSDs at around $2 per GB. That would put the 4 TB drive at roughly $8,000.

SanDisk expects to double the capacity of its SAS SSDs every one to two years in line with Moore's law, surpassing hard drive capacity:
