Seems pretty fast, I guess.

It was cheap
Cons Honestly, I can't notice the difference from my old ATA100 drive. It should be faster, but I dont see it.

Additionally, every now and then (at least 10 times a day) I get a sharp, short grinding noise. It does NOT sound right, but it passes all of the seatools tests.

The only reason i havn't rma'ed it, is because i'm just too lazy... sad... i know. But I got vista installed, word, and all my games... meh


Not really happy aobut this drive. It does not seem faster than my old drive, and it makes noises. Noises i have never hard a hard drive make... ever. I'm just hoping it does not fail on me.

I should RMA it, but alas im just too lazy. NCIX was nice though when I called. The guy didn't really make my feel better about the loud drive, but offered to RMA it.

I really hope this does not come back to bite me in the butt!

Good pric, fair capacity, 5yr warranty
Cons seems to have some reliability issues, altho mine have been fine.


I like these drives, they are zippy, fairly large, have good warranty from a trusted manufacturer. I have mine in a raid 0 config and they work awsome.

Experience: 3 Weeks

Verified OwnerVerified Owner


Works great, and at a great price.
Cons none really, its a hard drive, not much to say.


Seagate makes great harddrives. Period. This is more of the same, and won't break the bank. This is perfect for casual users who need some space, but not a lot. The SATAII interface is great, but ensure that your motherboard supports it.

Experience: 1 Weeks

Cons -Tends to get hot (around 45 if there's no airflow)
-Seek noise might irritate some


I bought 3 of these drives, all of them are working flawlessly. The first one I bought is still running strong after 2 years of almost 24/h a day of work. These are great hard drives.

Experience: 11 Days

Verified OwnerVerified Owner


Excellente qualité/prix et garantie
Cons aucun


Très bon disque dur ... surtout pour le prix. J'avais déjà un 250GB et avec ce 320 GB pour mon autre ordi, je suis comblé

Experience: 2 Weeks

Verified OwnerVerified Owner


fast enough
Cons too loud


I purchased this drive because it was a pretty good deal, but I am wishing I had paid a couple extra bucks for a Western Digital. I have this drive and a WD SE16 320GB in a RAID1 array. Unfortunately, compared to the WD drive this one is very loud. Of the 3 drive in my system, this is the only one I have to listen to.

Cheap, good performance, quiet.
Cons Rather warm temps, AAK firmware.


Have always had good luck with Seagate, this drive is no different. It's quiet and fast, and is a good price. The only downside really is it's quite a bit warmer than my other drives but nothing major. This drive shipped with the AAK firmware, which there have been some problems reported if you look around.

Experience: 18 Months


SATA2, Almost 0% failure rate, very quiet
Cons None


I current have two of these as external hard drives. They're highly efficient, very quiet and don't overheat. I've had them for a year and a half and not once has either failed even when the power cord is unplugged while in use (although I wouldn't recommend trying it).
