This drive might not be the best choice for an upgrade to a machine you build yourself, however as it is compatible with HP's Software Pre-installation Environment it makes a great deal of sense for an HP owner.  Benchmark Reviews tested the drive out and were impressed with the performance they saw; it did not match the somewhat inflated claims made below but it performed in line with the majority of the competition out there.  Take a look at the specific results in the full review.

"HP suggests top speeds up to 570 MB/s for reads and 525 MB/s writes from their 1TB SSD S700 PRO, which utilizes 3D NAND to deliver impressive storage density and reliability. In this article for Benchmark Reviews, we test the 1TB HP SSD S700 PRO (2.5″ SATA model 2LU81AA#ABL) against other solid state drive competition."
