Why are my cache reads so much slower than yours (by a factor of 2)?
Either something is making you use SATA I, instead of SATA II, but your
dmesg showed 3Gb/s, or perhaps that you have 8MB cache and I have 16MB
makes a difference.
A friend of mine has SATA I, with 1800 MB/s cached reads, which is also
much better.
I don't see how he can, SATA I = 1.5Gb/s = 1500Mb/s = 150MB/s (after
allowing for 8b/10b encoding)
Now I'm scratching my head too, even with SATA II = 3Gb/s = 3000Mb/s =
300MB/s how can hdparm -T show me 2229MB/sec? I though hdparm -T didn't
test o/s memory caching, just drive caching?
