Current SSDs aren't quite up to the 3Gbit/sec SATA rate yet,
- Sequential READ: up to 355 MB/s (SATA 6 Gb/s), up to 265 MB/s (SATA 3 Gb/s)
- Sequential WRITE: up to 215 MB/s (140 MB/s for 128GB drive)
almost 100MB/sec faster on 3.0
seems the reduced latencies of the communications helps
- READ latency: 55μs (TYP SATA 6 Gb/s), 70μs (TYP SATA 3 Gb/s)
- WRITE latency: 60μs (TYP SATA 6 Gb/s), 95μs (TYP SATA 3 Gb/s)
There's an SSD hd that you can buy that plugs into your PCIe because it does 1400MB/sec writes and 1500MB/sec reads with 20k IO/sec
yes.. about 1.5gigaBYTES/sec both ways.
The bad part is you can't boot from these because no SATA/SAS since it uses your PCIe. /sigh
wish I had a few extra $$$ in my pocket.
