One drive to rule them all and in the data centre bind them

It's a fancy-pants ruler-shaped form factor among Intel gubbins

By Chris Mellor, 8 Aug 2017

Intel has updated its data centre SATA SSD products, dual-ported its Optane drives and introduced a "ruler" format for server Optane and 3D NAND drives.

The DC S4500 and S4600 use 3D TLC NAND and come in 2.5-inch x 7mm format. They use the 6Gbit/s SATA interface and feature a new Intel-developed controller and firmware.

Model Capacity R' Read IOPS R' Write IOPS Seq Read Seq Write
DC S4500 240GB, 480GB, 960GB, 1.92TB, 3.84TB to 72,000 to 33,000 to 500MB/sec to 490MB/sec
DC S4600 240GB, 480GB, 960GB, 1.92TB to 72,000 to 65,000 to 500MB/sec to 490MB/sec

The difference is that the S4600 is optimised for more writes.

The endurance is one drive write per day (DWPD) for five years for the S4500 and three DWPD for five years for the S4600.

E8 is taking advantage of the dual-ported Optane drives, saying that it makes Optane suitable for use in applications needing high availability.

Forthcoming Intel 'ruler' format

The ruler format is said by Intel to enable more solid-state capacity inside thin server chassis, with it enabling up to 1PB of storage in a 1U server rack in the future. Both 3D NAND SSDs and Optane drives will appear, probably before the end of the year, in this ruler form factor. ®
