Pros: It's fast, it's quiet, it's thermally efficient! Low heat and awesome speed is why I like it, and this price is dam hard to beat for that kind of performance. Mikey likes it!

Cons: I installed this into a Lenovo R61i laptop which replaced a failed WD 80g 5400rpm drive. The problem I see, it's nowhere near 200 gigs of capacity, it's actually 127 gigs as recognized by windows. Perhaps I should have installed windows in compatible mode via the BOIS, or maybe that has nothing to do with it. I don't know for sure, but I have installed many drives in many computers and have never seen this kind of loss once XP is fully installed. I'm shocked and irritated about this issue, but there you go, that's the worst I can say about this drive thus far.

Other Thoughts: I wish Windows would calculate hard drive capacity the same way hard drive manufacturers do, or vis/versa! If I had it to do over again, I would have done a little more home work. Time was an issue since this was a customers laptop I was working on, bang for the buck is what he wanted so I found my top picks and gave the customer the choice! This drive is what he chose, he's happy and so am I. But knowing now what I didn't know then, I might have pushed for something else. Maybe not, since this is a performer drive, but all that lost capacity keeps me up at night if you know what I mean.

Pros: Worked Great for 18 months.

Cons: Died a terrible death after initiating a large file transfer.

Other Thoughts: It ran its course well but I would have hoped for more than 18 months from this drive.

Pros: -Fast (clear real world performance gains on MBP 3,1 in caching Finder views and sustained transfers)

Cons: -Noisy (I am generally not sensitive to computer noises, so I was surprised by how noisy this drive was compared to the 5400 RPM drive that it replaced. It continues to annoy me.)

Pros: Quiet, cheap

Cons: not fast enough

Other Thoughts: a good choice if you want to have higher speed than 5400rpm and don't want to pay much

Pros: This was a great macbook upgrade, and made a noticable difference in startup and application load times. I did not notice any obvious temperature increase, and istat only recorded a couple degrees over the stock 80g 5400.

Cons: Drive is dead, and DiskWarrior reports hardware failures. It took multiple reboots and lots of patience for DW to even mount the disk. I need to obtain another drive to backup my data because this one is too far gone, but I'm not sure that I even want to rely on the RMA if, as other reviewers are reporting, it too will fail in another 8 months.

Other Thoughts: Bought this in February, and it's been on several cross-country flights and long drives, but well protected. Death snuck up after the laptop spent a week parked on my desk running nzbDrop (heavy disk i/o), so unless this was a latent problem that finally blew up, it would appear that the disk finally couldn't handle heavy use over an extended period of time. Perhaps it's a better choice for business and casual users.

Pros: Faster than stock
Much more space that stock
Fairly quiet

Cons: None

Other Thoughts: I think this is as much space as you can get for a 2.5" drive. It does make loading and other operations faster on the PS3. Plenty of room now as well. Noise level is about the same if not less. The fans are louder.

Pros: 7200 RPM, 200GB. Was the fastest and largest drive on the market when I bought it about a year ago

Cons: The hard disk crashed after about 6 months of use

Other Thoughts: This was the second Hitachi hard disk that crashed for no apparent reason in the last year. Granted I do take my laptop with me everywhere, but I am not very rough on my equipment

Pros: I bought Hitachi to run my MacBook Pro, MacBook faster, it is very quiet like mac native HD.

Both Mac started cricking 2~3 month ago, Hitachi in MacBook just diagnosed-failed by MAC OS Install Disk 1 DVD hardware test.
Hitachi gave me a new replacement HD today.

I do not appreciate the quality of Hitachi drive, I looked for better made Fast HD, but nothing better out there really.........

Hitachi 7200RPM HD is just so much greater speed when it works!

I just have to make sure to back up all data.
(Hitachi service would not recover any data.)

Cons: Failed

Pros: Large size and speedy at 7200rpm. Very quiet as well.

Cons: Price

Other Thoughts: Upgraded from a 5400rpm hard drive and once I installed this in, the speed increase was noticeable. Giving it a four since the price is still high.

Pros: Fast Read & Write

Cons: Drive started clicking (making sounds of death) after 6 months of moderate use and then 1 month later stopped spinning. RMA to Hitachi is difficult. They require special packaging that is impossible to source. Hitachi sent me a 5400 rpm drive as replacement--I am not happy with Hitachi at all. I have contacted them to see if they will rectify the situation.

Other Thoughts: The performance of this drive is great, but it is not reliable. Hitachigst customer service is mediocre to poor. I would purchase Western Digital or Seagate over them any day--both their Customer Services are better as well.
