Ok, I think you convinced me, its not worth the money, I was just trying to find out exactly why its not worth it ...thanks for the tip about Amazon Glacier.

Ok, thanks, I know any drive can fail but isn't there a smaller chance that an enterprise drive will fail compared to a standard desktop drive? I guess there must be a difference. Or does it only make a difference when using the drive in heavy read/write server environments? I do have two internal RAID 1 drives for backup also, the external would only be as an addtional backup.

This is for business backup of important files. The computer is a workstation: Asus P8B WS motherboard, Xeon E3 processor, so the the system is made as a workstation. Is it still not worth the money to use an enterprise grade HHD for external storage?

Thanks for the reply. The reason I wanted to use the Ultrastar 7K4000 is because I was thinking it is more reliable and will last longer. Is that not the case? Will a standard desktop drive be sufficient? I do have two internal RAID 1 disks as backup, but I was looking for the best way to make a reliable external backup.

Will an enterprise level HHD such as the HGST Ultrastar 7K4000 work as a single drive or will it only work in an array as a RAID drive? I believe it is intended for RAID but Im wondering if it will work fine as a single drive. I want to use it as an external backup drive.

Thanks for for the reply. So how is this practically done since there will actually be two separate RAID configurations? Do I set this up in my computer's BIOS or Windows 7? I use Unison to make the backups. I will probably backup the HDD drives to an external hard disk also.

Im new to RAID so forgive me if this is a strange question. I would like to have two SSD's configured as RAID 1 as my primary drives for Windows 7, and then two HHD's as my storage/backup drives, also in RAID 1 congifuration. So if I store a file from my primary drive(s) then its automatically saved on both backup HHD's at the same time. Is this possible or even recommended?
