RAID 5 disk speed impact on gigabit NAS
Posted on 2008-10-13
I have purchased a NAS device which is connected to my network via a gigbit network connection.
I have 4 * 7.5k rpm disks in this device in a RAID 5 configuration.
My supplier recommended not getting 10k drives as he said 'the network will be the bottleneck'... however two of these disks went wrong recently resulting in data corruption - I am wondering if there is an advantage to be gained in having faster drives sue to the fact that the RAID needs the best speed possible to do it's striping etc?
Would having faster drives be better for such a setup?
