I recently completed building a home theater server which has 6 SATA 2TB drives made by Western Digital (WD20EVDS). I was surprised that these were a little slow - running about 80MBPs on a SATA3 channel.
Passmark shows:
Sequential Read 95.4 MBPs
Sequential Write 93.3 MBPs
Random Read + write 2.36 MBPs
I was a little shocked. So I went out and for comparison got one of what was called on this sight the fastest drive in the world. The WD2001FASS
Now mind you when I tested this drive it's connected via eSATA but don't think that should make that much of a difference.
Results from Passmark show:
Sequential Read 101.8 MBPs
Sequential Write 88.5 MBPs
Random Read + write 2.85 MBPs
Virtually identical! And the WD2001FASS was supposed to have a max sustained speed nearing 136MPs.
What gives here? Is there something amiss on my motherboard that's causing this? I can't understand why the world's fastest drive is 40% slower than advertised and virtually the same as the drives I have now.
Any tips or ideas would be greatly appreciated.
Thanks
