test your disks in linux

I have a linux server which has 2 disks on it. one of them is SSD and other is SATA disk. I wondered how fast is ssd is here is the output 🙂 root@mascix.com: ~ # hdparm -t /dev/sdc /dev/sdc: Timing buffered disk reads: 598 MB in 3.00 seconds = 199.03 MB/sec root@mascix.com: ~ # hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 266 MB in 3.00 seconds = 88.55 MB/sec I should say this test done when server has load on it. pretty nice
