The guys from Tom’s Hardware have a lot of time and solid-state drives on their hands. They compiled a list of 14 SSDs and compared them. In the end, they feel (just like I do), that SSD isn’t really the best choice right now. The technology is still too new and expensive, so the benefits do not justify the cost — yet.
If you’re dying to know and really don’t want to read the whole thing, let me save you some time. All of them are pretty evenly matched. The only difference is that some of them are faster at reading/writing and others are more energy efficient — but never by that much.
The only one Tom’s Hardware thought was really worthwhile was Samsung’s 64 GB SSD SATA-2 drive, which was the complete package at a reasonable cost. I hope the 128GB ones perform as well.
