Pros: Compact size, password protection, reasonable price.

Cons: I gave 1 star in my earlier review for this, as the drive came unformatted and it could not be formatted by win-XP. So, I downloaded the driver from Memorex and could format using it. So, changing to 4 stars. Would have 5 stars if I did not have to go through this.

Pros: Quiet, fast and highly reliable drive. I burned about 25 SL/DL DVDs so far, and only one failed due to a visible scratch on it. Reads a single layer DVD (4.7GB) in about 5 minutes, and burns in about 5 min 20 secs.

Cons: If you power off the drive when the PC is in standby, you have to reboot the PC to recognize the drive again. I have not checked how to overcome this issue.

Overall Review: I read about external drives that do not require a power adapter, but I doubt about their burning speed and reliability when they are powered from USB interface. You can also find cheaper drives with similar specs, but if you want quality and reliability, just go for this!
