An Accelerator Series SSD cache drive doesn't replace your hard drive — it just makes it faster. Installation takes just minutes. There are no configuration hassles and you'll start to experience the improvement immediately.
KitGuru recommends Corsair Accelerator Cache drives with their 'Worth Buying' award.
"We are quite impressed with what the Corsair Accelerator cache drives have to offer. In our tests, we saw significant improvements in performance with the cache drives enabled compared to the hard drive alone. In some cases, the performance was very close to that of a dedicated SSD." "We think that the 30 GB drive is a great way of boosting your system’s performance without spending very much money."
“Rather cheap, the Corsair SSD Accelerator fulfills its mission. It will be an excellent addition to your hard "system" containing Windows and programs. However, it is not advisable if your disk hosts mainly multimedia files, as it may slow down file transfers.”
