Hi

I have just installed 2 brand new Samsung F4 2TB drives in an HP Proliant Microserver. Installed Ubuntu 11.04 and formatted the disks as EXT4.

I tested the drive speeds using hdparm -t and one reports as around 140 MB/sec and one reports 130 MB/sec for buffered disk reads. I have re-run the test seveal times and results are always around the same.

Can anyone advise why there would be a difference in the speeds?

Thanks
