Pros: I own 4 Seagate Barracuda drives that are used on a daily basis and some for offsite backup. I use Macs so I format them as Mac Journaled when I receive them then start using them. I have never once had a problem with any of them. Some are daily users and are plugged in all the time others are in enclosures that are for weekly or monthly backups and kept offsite. Like my Macs- they just work.

Cons: I've bought 500G drives when I should have bought 1T drives and I wouldn't have to buy as many. Oh, that's a problem with me- not the drives.

Overall Review: One store employee refered me to Seagate Barracuda when I bought my first bare drive, it is still working so I keep buying them. A friend just told me about 2 of his 3 WD drives dying. I guess I made the right choice.

Pros: Looks good, comes with everything you need, easy to set up, price, sturdy

Cons: Fan is the loudedst thing in the room and can't be turned off. 2 of us bought this same unit for use with our iMacs. Configured as JBOD. Both of them eject discs randomly on their own, often happens when machine is coming out of Sleep mode but not always, sometimes discs are just ejected for no apparent reason whether in use or not

Overall Review: Very unreliable and a hugely dissapointing purchase.
