i just got a free SSD trial from verlox.com.
Fast test, fast result : Fake SSD.
Doe this look like SSD ? No it doesn't.
[root@test ~]# dd if=/dev/zero of=sb-io-test bs=1M count=1k
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 7.19174 s, 149 MB/s
[root@test ~]# dd if=/dev/zero of=sb-io-test bs=1M count=1k

[root@test ~]#
This is pure HDD disks server, I run it this test too which clarify things out for everyone :
[root@test ~]# cat /sys/block/sda/queue/rotational
1
[root@test ~]#
I should get 1 for hard disks and 0 for a SSD.
