  • This older device is fast enough to use for occasional file transfers, but those read speeds are way too slow to deliver any performance benefit to a Windows Vista PC. It fails.

  • This 1GB drive from A-Data, purchased from an online outlet store, just failed to clear the minimum required write speed on the first test pass.

  • After retesting the previous drive, write performance cleared the minimum threshold, but this drive couldn't deliver that speed across the entire drive. Its design uses a single fast 128MB flash chip matched with slower flash chips. Because it couldn't deliver consistent results, ReadyBoost refuses to use it.
