One of my Samsung Spinpoint F2 EcoGreen (HD103SI) disks has just failed. It's within Samsung's three-year warranty, so I set about obtaining an RMA number to return it for replacement. In their RMA terms and conditions it states:

Quote:
For RAID system like a NAS, Samsung allow you to use RAID models only. Visit http://www.samsunghdd.com for more information. If you use an incorrect product installed in your RAID system then Samsung will reject your warranty request.


So, two questions. Can Samsung legally impose this condition long after the purchase? What exactly is a "RAID model" drive? I can find no information on their website about which drives are intended to be used in RAIDs. There is no mention of "RAID" in the overview or the specifications for any of their hard drives.

I can't speak of the Samsung drives ant their RAID certified drives but I know that Seagate drives with the NS at the end are for near line storage and are certified for use in raid systems.

These drives have firmware on them that is designed to cope with the added harmonic vibrations of the drives in a chassis where there are a bunch of HDAs hammering away at the same time. When the heads are positioned they move VERY fast and when a bunch move at the same time they can effect others that are close and mechanically coupled through the chassis causing possible seek errors.

WD, Seagate, and Samsung all pull this crap. The drives for Nearline storage are much more expensive, on the other hand they are also warranted for 5 years and I have found them to be very reliable.

I would send in the drive anyway and not mention the RAID at all.
