Windows Vista Ready Boost
We used IOMeter to check out the drives’ aptitude for Windows Vista’s ReadyBoost technology. The speed of reading random 4KB blocks and the speed of writing random 512-byte data blocks were measured. The test ran for 10 minutes.
The drives from Patriot, SimpleTech, RiDATA, TwinMOS and OCZ didn’t reach the 2.5MB/s limit at random reading. The flash drives from Kingston are the best ones in this test.
This test is a disappointment. Every drive is too slow here. There’s no talking about surpassing the 1.75MB/s barrier because each drive has a too low speed of random writing. But of course, it’s Windows Vista itself that’s going to say the final word.
