15.36 TB SSD enough for you?

Samsung are now shipping the 15.36TB SSD hard drive in the form of a 2.5″ drive.

Certainly, in the world of home computing 15TB is a bloody lot of data storage. For a business, not so much. But in a SAN along with 10 more of these you’ve got yourself some very fast storage for a small business. I think I would have a mechanical array that is of the same size (in TB) so I can back the SSD back to a mech drive. Not that I don’t trust the SSD, far from it, my main machine has 2 of them. Backup data is a must.

Flashpoints for the PM1633a:
12Gb/s Serial Attached SCSI (SAS)
“3D” storage
The 15.36TB PM1633a drive supports 1 DWPD (drive writes per day
Sequential read and write speeds of up to 1,200MB/s.
Random read and write speeds of up to 200,000 and 32,000 IOPS respectively

From the news release:

The unprecedented 15.36TB of data storage on a single SSD is enabled by combining 512 of Samsung’s 256Gb V-NAND memory chips. The 256Gb dies are stacked in 16 layers to form a single 512GB package, with a total of 32 NAND flash packages in the 15.36TB drive. Utilizing Samsung’s 3rd generation, 256-gigabit (Gb) V-NAND technology which stacks cell-arrays in 48 layers, the PM1633a line-up provides significant performance and reliability upgrades from its predecessor, the PM1633, which used Samsung’s 2nd generation, 32-layer, 128Gb V-NAND memory.

Impressive tech! It’ll be great to see this in a commercial setting.
