G.Skill Phoenix Pro 40GB SSD review

Another nippy SSD, but is it worth it when larger SSDs are around?

Our Verdict

For

  • SandForce controller is still a peach
  • Great single-drive performance

Against

  • RAID 0 application performance not that impressive
  • Expensive compared to a conventional hard disk

What you really want from a RAID 0 array is double the performance, especially considering the not inconsiderable outlay you'd be spending on twin SSDs.

In synthetic terms, things look good – both the read and write speeds get the expected boost. It's the real-world tests that don't bear out doubling your purchase. The application performance in both decompression and application installation times don't really tally with the synthetic scores. However, this is probably down to the old SATA II interface than the drives themselves.
