Seagate Momentus 7200.4 ST9500423AS 500GB 7200 RPM RPM 16MB Cache SATA 3.0Gb/s 2.5" Internal Notebook Hard Drive

Pros: I used this in a Toshiba Satellite notebook, which had a 160 GB drive in it that failed. Before that drive became unreadable, I was able to copy that partition over to this one and then expand the size. No Problem at all, still no problem. I maintain this computer as one of my monthly clients, it has been working swell all this time.

Cons: Nothing really bad, I ahvent seen the same failures others have had.

Other Thoughts: I've read all the other reviews, but simply put, none of that ever happened to me. I found this drive very durable, and it speeds up a Windows 7 system noticably. I would certainly consider getting more of this exact model, I don;t knwo why they went bad for the others, but as I have said in other reviews, drives are made in batches, and sometimes a whole batch has some error that causes the same problems troughout the batch. Seagate is pretty good with returns and sometimes even give you larger drives as a replacement, like WD does sometimes. But for this drive, it is still working well, under warranty for another year and a half at least should that happen.

Pros: Standard

Cons: will die someday

Other Thoughts: Came with my Dell laptop. I've used it pretty heavily for 3 years, including 3 formats and re-installs of Windows. Just died though. 3 years seems decent for a drive, but that doesn't make it any less poopy when it happens.

Pros: Was fast when it worked.

Cons: Dead shortly after the 2 year warranty. All it does it beep when mounted

Pros: quiet and relatively low powered. I got two of these in a big laptop from Dell.

Cons: Not reliable. One completely broke (won't boot, won't read, nothing) within 10 months of purchase.

Pros: Extremely quiet and decent speed.

Cons: Fatal errors (system freezes) after about 15 months of use, under certain conditions (opening specific programs were guaranteed to lock up the drive). Drive is unusable after 22 months and an attempted factory reset.

Other Thoughts: This drive came as part of the ASUS G51JX-X1 purchased in December 2010. Worked great until this March. Was able to isolate the culprit programs, but that limited what I bought the laptop for in the first place. HDD Regenerator 2011 labeled the drive as "Imminent Fail," and continually found surface errors no matter how many times it attempted to regenerate them. Tried to run a factory reset with packaged AI Recovery software, but consistently get "WimSetReferanceFile 2 Failure" once the windows recovery process starts. Troubleshooting, plus previously mentioned indicators, point to critical drive failure. Replacing with Seagate Momentus XT ST95005620AS 500GB Drive.

Pros: Flawless purchase. Exact product I needed. Full operation on antique W2K Tower machine with increased speed and SMOOTH operation. Ordered 2 more of these beauties!

Cons: None! No pain, no strain:] W2K loves these sweeties:]

Other Thoughts: They just get more and more easier to afford, use & keep going.

Pros: Decently fast and low noise

Cons: Bad sectors and death within 9 months. Extremely disappointed.

Pros: Direct replacement for an earlier 60 GB drive.

Cons: Only lasted about 6 months before I started experiencing fatal system errors.

Pros: 7200rpm, 16mb cache

Cons: N/A

Other Thoughts: i have 2 of these drives and im currently using one of these in my new lenovo Y580 and the other is in my foxcon NTA350-0H0W-B-A-NA their nothing exciting just some 7200rpm 2.5"...i acquired these drives with my asus g74 gaming laptop

Pros: It's shiny

Cons: This drive was OE in an HP ProBook 4530s that I had drop-shipped to an employee. About a month later his computer started blue-screening after about 5 minutes of operation. He shipped the notebook to me and the HP diagnostics confirmed the drive was bad.
