Two in a row have failed,
I am not going to say there is something wrong with these drives, because at the end of the day I’m only one guy with a bad experience. I’ll just offer my review here so that people get a full perspective. I have had two of these fail on me in a row, failing offline SMART tests. When it was working, the drive was very fast and quiet, though, so I can certainly understand the high marks people give these drives when they work.
I think it is fair to say that Seagate is really running these at the ragged edge of what is possible. While the transfer rates can approach 90 Mb/s at the edge of the platter, according to a few quick tests I ran, the transfer rate fluctuates greatly, and the drive shows a pretty constant stream of software-corrected (ECC) errors. In other words, you’re not losing data, but the data coming off the drive is on the border of what is readable, such that the drive needs to rely on error correction and/or rereads (hence the fluctuating speeds) to get the data off. I base these conclusions on the fact that tests of data on the inside of the platter (which has much less speed) are much more reliable (albeit slower).
If you do decide to get one of these, do yourself a favor and backup (which you should do anyways, because all hard drives are subject to fail at any time).

|Do your research….,
Read the 5 pages of support issues on this drive in Seagate’s forums or the 30+ pages in Apple’s forums (and note: this isn’t an issue exclusive to Apple systems)… or read the reviews at Newegg… this drive has MAJOR reliability issues.
Don’t believe all these 5 star reviews from people who reviewed the drive the day they installed it. It will run great when you first put it in.
But 15-60 days in you will start hearing clunking noises. Your system will start freezing for a second or two here or there. The drive’s load cycle count will start to skyrocket (to the point that even under “normal” use the drive will fail within a year by Seagate’s own numbers). If you’re really unlucky, the drive will suddenly die.
Don’t play russian roulette with your data. Don’t fall for this drive’s relatively low price or nice specs.
The most important spec in a hard drive is reliability. This one sucks.

|Seagate Momentus 7200.4,
I was really worried to buy this drive cause of the reviews I read, but I bought it because of the reputation of seagate, as my old drive was seagate momentus too but 160 GB, I did replace it with this 500 GB model, and found no Vibration as many people claimed, the same as Hitachi, western Digital.
I ordered two hard drives
Installed the first in a Macbook Pro 17″ 2.4 GHz SR, everything is perfect. I am not sure about the battery life after replacing the drive as I did upgrade the OS to snow leopard afterwords so I can’t judge the battery level fairly.
The second drive did install it in a White Macbook 2.4 Ghz, to replace a 5400rpm 160 GB Hitachi, there is a real significant difference between the old Hitachi, and this drive for sure, the Macbook is really flying now, boot times are faster, and applications load fast too. The over All performance did boast I guess 40% more.
White Macbook:
Vibration: No
Speed: Yes
Battery consumption: Yes, the battery don’t last as the 5400 Hitachi
Worth Upgrade: yes 100 %
Macbook Pro:
Vibration: No
Speed: Yes
Battery consumption: Yes, the battery don’t last as the 7200 160 GB Momentus
Worth Upgrade: yes 100 %
I do recommend this product
