Dunno, I find 1.2-1.6GB/sec on my samsung s950 all the time. The benchmarks I've seen do not show any noticeable difference between SATA and NVMe. Sure geeks

Dunno, I find 1.2-1.6GB/sec on my samsung s950 all the time. The benchmarks I've seen do not show any noticeable difference between SATA and NVMe. Sure geeks like the idea of a lower head protocol, but truth is the protocol is not the bottlneck.
Seems like Optane is a solution looking for a problem to fix. Normal M2 SATA's do fine:
# dd if=/dev/sdb of=/dev/null bs=131072
1953586+1 records in
1953586+1 records out
256060514304 bytes (256 GB, 238 GiB) copied, 159.18 s, 1.6 GB/s
(cold cache on a machine with 16GB ram).
- eyeinthepyramid 10y agoYou're looking at throughput numbers, but Optane appears to be solving a iop / latency problem.
- wtallis 10y agoYou're not getting 1.6 GB/s out of a SATA drive that's communicating over a 600MB/s link. I think you may be confused about which products are using SATA vs PCIe.
