OCZ Vertex 4 Review (256GB, 512GB)by Anand Lal Shimpi on April 4, 2012 9:00 AM EST
The Vertex 4, similar to the Octane before it, consumes entirely too much power at idle. OCZ tells us that this is a known issue, also fixed in the next version of the firmware that should reduce bring it down to roughly 0.75W at idle. At ~1.3W today, the Vertex 4 would draw more power than many 5400RPM 2.5-inch hard drives at idle - something to keep in mind if you're planning on putting this thing into a notebook.
Under load however, the Vertex 4 does quite well. It's more power efficient than Samsung's SSD 830, while offering similar if not better write performance. If your aim is better battery life and not performance however, you may want to stick with one of the 3Gbps Intel drives instead.
