Pros: Very quite. Installation was easy.

Cons: Compare with Toshiba drive that comes with 16 MB cache, this one is noticeably slower. I did not feel it is faster than my old drive which is a Travelstar came with IBM x24, 42000 rpm, 2M cache.

Overall Review: Even the speed seems not as what I expected. However, I am very happy with this drive. I finally settled with this drive, after RMA two Toshiba drives that are incredibly fast. However, both made high pitch noise that can't be tolerated. This one is slower than the other one, but I can live with this.

Pros: Fast and easy installation.

Cons: The drive makes high pitched noise, even when it is idle. The high pitched sound may be tolerate if you only use the computer in a short period time. But it is squeaky enough to make you uncomfortable and loosing concentration, if you have to work for a long period of time.

Overall Review: As a Toshiba tech told me that the noise may be caused by the defection of that particular drive. I am RMA this drive, and will see the replacement.
