15K SAS disk problems

Hi,

 

We bought a DL380G6 in the Summer of 2009 and populated it with 3 x 15K HP 2.5" disks (504062-B21) in RAID5. A little while later we added 3 x 10K disks as a separate RAID5 array.

In the 18 months or so that the server has been running we have had no fewer than 4 failures on the 15k disks. So far, the 10k disks have been fine.

It seems to me that 4 disk failures in 18 months is an unacceptable level of reliability, certainly much worse than anything I've experienced before.

Has anyone else had trouble with these disks?

Thanks, Ian.
