Toshiba joins the exclusive, three-member 6TB disk drive club

Toshiba has joined Seagate and WD/HGST in the 6TB disk drive club, still so exclusive that it only has three members.

Boffin finds formula for four-year-five-nines disk arrays

Forty-five disk drives, ten parity drives, and 33 spare disks: that's the optimum array size to protect data for four years with no service visits, according to a study published at Arxiv.

Seagate's bought a disk drive array firm. Déjà vu? You betcha

Seagate has tried making a go of the disk drive array business before, and failed. Now it has bought a disk array supplier for the second time.

Disk is dead, screeches Violin – and here's how it might happen

But flash array flogger Violin Memory is convinced disk is dying in the data centre, killed by a series of NAND acronyms: 2D MLC, 3D TLC and, the final blow, 3D QLC. Is this view realistic? Even remotely realistic? It starts from a pair of observations by Violin …

Flash could be CHEAPER than SAS DISK? Come off it, NetApp

A NetApp pitch at the Flash Memory Summit said the cost-per-GB price trends for cheap TLC flash mean it will dip below SAS disks in 2017.
