I bought two SSDs,which are exactly same, but sequential write performance varied widely? sdb
is the first SSD, sdc
is the second SSD, and partitions are same(both sd*1
and sd*2
)
and the sdb1
's sequential write is 223MB/s but the sdc1
's sequential write is only 161MB/s
What could be the cause of this?
1both are connected to SATAIII ports? – Ramhound – 2013-10-15T15:51:55.233
Try and change the ports over. On my motherboard there are 4 SATA3 ports and 2 of them are from a different chip and are slower. – Richard Powell – 2013-10-15T15:56:06.820
swap sata cables and test again? perhaps a bad cable? – Keltari – 2013-10-15T15:56:09.097
also, are they at the same firmware revision? – Keltari – 2013-10-15T15:57:32.757
