Hi all
I just test speed of my disk and see SSD is slow.
sdf is a SSD
sde is a HDD
result for sdf :
Code
~# hdparm -t /dev/sdf
/dev/sdf:
Timing buffered disk reads: 236 MB in 3.08 seconds = 76.69 MB/sec
root@nas:~# sudo hdparm -Tt /dev/sdf
result for sde :
Code
hdparm -t /dev/sde
/dev/sde:
Timing buffered disk reads: 544 MB in 3.01 seconds = 180.73 MB/sec
I dig a little and see that : SB7x0/SB8x0/SB9x0 SATA Controller [IDE mode]
Do you kow if I can safely change IDE mode to AHCI in the bios ?
Code
sudo lshw -class storage
