Sequential write speed dropped 200MB/s raid array?

Hey,

Since using my raid array, the sequential write speed has dropped a hell of a lot. Is this due to fragmentation or some other problem that I can fix? When they were empty they were pulling 287MB/s and are now down to less than one hundred?

Thanks for any help

Hey,

Sorry mate, No I've got two sammy spinpoint F4's in raid! The write speed has dropped hideously!

Thanks for your help so far

Hey,

Crystaldiskmark is what i've been using, perhaps the wrong choice?

Thanks

Hey,

Read speeds have dropped 20mb/s over the blank disk benchmark, certainly not 200+ as the write speeds have! Volume is 8% fragmented but would that cause that serious a drop?

Thanks for your help
