Re: Poor performance of ExtremePro 240GB

[ Edited ]

I have a ocz vortex and a Samsung 850 Evo, listed below in order. Why are my Timing buffered disk reads so much better than his  'Timing buffered disk reads: 576 MB in 3.00 seconds = 191.84 MB/sec' ? With the Sandisk Extreme Pro, shouldn't the Timing buffered disk reads be better?

 

 

I am using just normal Sata cables on a 5 year old motherboard. 

 

 

localhost linux # hdparm -tT /dev/sdc
/dev/sdc:
Timing cached reads: 6890 MB in 2.00 seconds = 3446.09 MB/sec
Timing buffered disk reads: 672 MB in 3.00 seconds = 223.69 MB/sec
 
localhost linux # hdparm -tT /dev/sdb
/dev/sdb:
Timing cached reads: 6994 MB in 2.00 seconds = 3498.00 MB/sec
Timing buffered disk reads: 798 MB in 3.00 seconds = 265.85 MB/sec
