Seagate Barracuda 7200.11 1 TB SATA 32 MB Cache Bulk/OEM Hard Drive

I dunno what the negative reviews are for... small print indicates they are NOT about the ST31000333AS, but another drive. I bought my ST31000333AS over a year ago, use it in an external Vantec case with firewire connection. Blazing speed, never a problem. Note that if you buy the drive alone you don't get rails, disc, anything but the drive itself. If you want a kit with all the cables, etc, then go for that and pay more. I was using Western Digital HD's for years, finally gave up after the n-th one died. Been using the Seagate Barracuda line exclusively for several years now, 300GB, 400GB, 1TB. No complaints. They run so quiet you don't know they're there. Highly recommended.UPDATE 10/10/17: I had to respond when I saw comments from 2010. I purchased one of these drives in Dec. 2009. It's now 2017. It's still running -- though it's getting noisy sometimes. That's high-tech talk for "nearing the end of its life." 8 years. Not bad. I've had good experiences with Seagate drives for 20 years. I've got ones that have been running virtually non-stop for 3,4,5+ years. Have I ever had one die? Yes. But I'm buying a replacement for my 2009 333AS today --- a 2GB ST2000DM006. What more can I say?

I bought this about six months ago when the price was much higher, but I still feel like I got an exceptional deal. This had NCQ (native command queuing) that most drives do not. That means when files are highly fragmented, the disk drive itself intelligently reads the files according to where they are positioned on the disk and then puts it back together before sending data to the computer. The result is a faster disk than one that doesn't have this feature. I had zero problems with this disk, unlike one of the 1.5 TB drives. I had to send that one back for exchange and got one back that vibrates slightly. So, I plan to purchase another 1 TB disk with NCQ to complement the one I have. I may make it into a RAID configuration.

1 TB is lots of space,drive performance is ok,its supposed to be 32mb cache but it take little lag to open the programs.

I had very bad experience with Seagate so far.The story starts with a 500GB internal HD I bought. This one dropped dead after less than a year. Since Best Buy told me I must contact Seagate and I didn't feel like going through all their support process I just bought a new Seagate 1TBHD (not a smart move of course#. This HD started giving me the clicking sound after 1 month. Additionally it started not being accessible once in a while meaning this baby was about to die on me.This time I contacted Seagate support. We went together through running their diagnostic SW and the decision of the support person was to RMA the product.After going through the RMA process on Seagate site I printed the shipping address they provided and shipped the product right away. Guess what. Address they gave me was wrong.After the box returned with a note that this address is not valid I logged into the Seagate site, put in my RMA number. Guess what. They now say this RMA number doesn't exist #and I have this number printed and in an e-mail from Seagate).Finding this experience unbelievable I can only recommend to stay away from this company. Their products fail and they don't support you once this happens. This at least is my experience with them.Product link: Seagate Barracuda 7200.11 1 TB SATA 32 MB Cache Bulk/OEM Hard Drive ST31000333AS
