Pros: I bought 24 of these for my new 80TB file server. I did not expect all of them to work out of the box, but they all did. I am monitoring the disk failures with my Adaptec RAID card and so far only one out of twenty four drives had to be RMAed within the first two months of use. As opposed to some of the other drives I have tried all of these drives ran at the 6GBps!
Cons: One drive had 32 "medium" errors within the first two months of use. I sent it off to the Manufacturer with the promise they would send me back a new one. I have not gotten one back, but that is OK as I understand the process takes weeks.
Summary: Using Windows 7 64-bit. Plugged in the drive, turned on the computer, windows saw the drive and asked to format, I chose the option recommended for drives larger than 2TB, quick format and done. Didn't even need to use their software. One partition, 3.63 TB (about 500MB larger than 4 'marketing' TB).
Pros: Reliable, huuuge storage capacity. I do a lot of video editing and use up a lot of memory, so this drive is a huge boon. For most others, this is probably the only drive that you need, unless you want to be able to write to a couple drives simultaneously to increase speed or responsiveness. Easy install, fast shipping.
Summary: Twice I lost everything on the drive and had to reformat it through 'disk management'. My motherboard supports 3TB+ drives. I have ran 'SeaTools' and everything checks out.
Pros: Lots of storage.
Cons: Drive keeps disappearing from my Windows 8 machine. Using it to store lots of video files. Seems to disappear after heavy use. Rebooting machine will usually solve the problem, but I should not have to do that.
Pros: Cheap for the size, when they work they're great.
Cons: High failure rate in my experience of the higher capacity drives. Feels like half the drives I get fail or have problems. NAS, Enterprise, and even Retail sometimes work out better than Bare drives, and usually better warranties, but are usually more expensive. New tech too often have bugs and issues that need to be worked out.
