Experience: 1 Months


Worked Without any problem on the first try, worth to buy it so far
For me the price is abit high but well it is the buyers decision to decide wether to buy or not.
I heard that this thing is not that great.but for more i really like it. I think it was what i wanted to be.

Experience: 2 Months


Very quiet.
There's better, but cost/gb is very good. I got it on sale about two months ago when I built my computer.

The only major problem I have is that it crapped out on me after two months. I got two of the same HDD too... I hope the other one doesn't fail on me because it hasn't. If it wasn't for the long warranty then I'd probably be extremely irritated. But every once in awhile there's a defective HDD.. right?

Signal To Noise
Experience: 2 Days


Good perfomance
5 year warranty
May need to use the warranty eventually (possibly)
I usually prefer Western Digital drives overall, but this was priced well and I needed a new drive for my external SATA drive enclosure. So far, so good. Drive is not audible during file transfers. File transfer speed seems to be above average.

Experience: 55 Days


Good price/value
Seagate has a great warranty on their drives versus other vendors. 640GB for $73 on sale is decent value. Haven't tried any benchmarks on it, but it works, and that's the most important thing.

Experience: 2 Years


fast, good cache, good warranty, big space
i got this 2 yrs a go and it rocks. 7200rpm is ok-good for games. it also has 32m cache mem, so that's good.

Experience: 1 Months


Good Speed
Summary this on sale for a great price; can't go wrong with the price ratio compared to 1TB drives...I've always been a fan of Seagate drives...

Experience: 1 Months


Had best GB/$ ratio
Smaller capacity
Got this on a sale and it was a good deal. Chose it over a 1TB drive and I'm not disappointed. Fast.

Experience: 30 Days


5 yr Warranty
I Like Seagate drives. I have two 500 and just bought two 640's at a very good price $73. So far I have not had any problems. They do what they are supposed to do. I have not had to use the warranty on the other Seagate drives, I hope these are the same. I'd continue buying Seagate drives.

Experience: 5 Days


Fast, easy to install, quiet, don't run warm
Bad quality control from Seagate
I bought 2 of these drives on the 25 of September, I didn't get them till Oct 4th. When I got them both of them had loud clicking noses and caused my computer to take much longer to boot up. Both of them were from a Thailand plant and I do know that they have been having quality problems from Thailand plants.

I RMAed them, sent them on the 10th, I didn't get them back till Oct 29. The drives I got back are also from a Thailand plant but they seem to be working pretty good. They are fast and quiet.

Depending on the price, I might consider getting more again, but I would really have to think about it. Just the fact that the quality control problems are not limited to the 1tb drives or higher is annoying and is whats making me think twice about them.

Experience: 30 Days


As fast if not faster then any drive on the market.
Reliable, most of the time.
5 Year warranty.
Seagate seem to have soem QC issues as of late, lots of people are having issues with different drives from Seagate. The 5 year warranty will come in handy then.
What can be said about the slowest part of a computer system. It does seem to perform faster then my older generation Seagate drive, although only the benchmarks seem to be able to tell so far. It does run smooth and quiet and for $150 for 1.2 TB running in raid 0, you can't really complain too much.
