Hi, my server currently has eight of the WD1500BLFS drives in hotswap bays. So that’s 147GB, 2.5", SATA. I’m looking to upgrade my server capacity, and the new 2.5" SATA VelociRaptors have my attention, specifically the WD1000CHTZ or WD5000BHTZ. Both of these are listed as “enterprise” drives, but they are also listed under “workstation”, not server. I have questions about the following points:
Are these drives recommended for use in a server environment?
Are they compatible with hardware RAID (Adaptec 5805), e.g. do they do TLER? I have had some issues with the current drives falling out of the array on occasion, but they always rebuild ok after a reboot. I just found out about this issue where some “consumer grade” drives take a long time to recover from an error condition, which makes the RAID card time out and drop the drive from the array. This sounds a lot like what has been happening with me. So I’m wondering if these new “enterprise” Raptor drives I referenced above are made for RAID environments or not.
Is there anything special about having a “hotswap” bay? Do the drives need to be aware of this, or will they be just fine? It seems to be a standard SATA connector inside, just that the drive is attached to a handle/rail that means it can easily be removed and reinserted. Not sure if that needs something special in the drive firmware.
I notice these 2.5 VelociRaptors come with this IcePack cooling enclosure. Is it ok to run them in a tight multibay environment without that enclosure? The server has internal fans bringing in air from the front, so there should be some cooling from that. The current drives have been fine running 24/7 since 2008.
Any clues much appreciated…
