Pros: I purchased this product to replace my Sony Vaio X505's 1.8" HDD. The factory unit has a 20GB drive. I have two notebooks so I was able to do a side by side - clean install using the different drives. The difference is amazing. The read went from 15.5 MB/s to 49.7 MB/s, and it was a steady reading from 0-32 GB. The 32GB SSD drive is 220.64% faster then the 20GB drive! I couldn't ask for more!

Cons: Price. You pay more per MB then you would otherwise. Also, I had to remove the drive from the outer casing for it to fit in the notebook, but that wasn't a big deal.

Overall Review: This isn't the world's fastest drive by any means, but if you have a notebook with a 1.8" drive, and you have the money, you're nuts if you don't try this.
