Samsung begins shipping a 15TB data center SSD

We often think of 1TB or 2TB SSDs as massive in PC enthusiast circles these days, but those drives pale in comparison to Samsung's latest. The company says it's now shipping the PM1633a SSD, a 15.36TB monster that talks to host systems over a 12Gbps Serial Attached SCSI (SAS) interface. That eye-popping capacity comes courtesy of 32 512GB flash packages built with Samsung's 48-layer 3D V-NAND.

The PM1633a is specified to deliver some impressive performance numbers to go with all that room. Samsung says the drive can hit sequential read and write speeds of up to 1200 MB/s, plus random reads of up to 200k IOPS and random writes of up to 32k IOPS. The drive's SAS controller is backed with 16GB of RAM.

Befitting a business-class SSD, Samsung says the PM1633a can endure a full drive write per day over its lifetime. The company also builds in "a highly dependable metadata protection mechanism" and includes a data protection and restoration utility that apparently helps system administrators recover the drive from momentary power interruptions.

Along with the 15.36TB range-topper, the PM1633a series will be available in smaller capacities from 480GB to 7.6TB later this year. Pricing for the drives wasn't announced.
