Re:Intel's roadmap for Optane SSDs with 1,000x performance by olavgg on Monday June 13, 2016 @04:01PM (#11897036)
Basically on a PCIe 3.0 x4 maximum performance is 4000GB/s, in practice this is 3200-3500MB/s. With 4k random write, you will get maximum 800.000 to 875.000 iops per second. Consumer-grade SSD's barely manage to write 500-1000 iops when sending the ATA_CMD_FLUSH command unless they are lying which is really bad.

Good read about consumer SSD performance: http://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test...

nitpick: iops is I/O operations per second. iops per second is redundant -- would be like FLOPS per second.

and I still use ATM machines....

Right, elsewhere in these comments it was pointed out that they are talking about a 1,000x improvement in latency vs flash memory. If they are using PCIe x4 and x2, then it seems that their throughput isn't going to be much better than existing SSDs.

Improved 4k random read and write would of course sill be a big win.

You made a 3 order of magnitude jump. Is that a typo?
