Windows Vista ReadyBoost
Although the discussions about ReadyBoost technology integrated into Windows Vista are far from being over, we can’t but check the drives out for their support of ReadyBoost. To remind you, the flash drive must have a capacity of 256MB to pass this test. Moreover, it has to deliver a speed of 2.5MB/s when reading random-address 4KB data blocks and a speed of 1.75MB/s when writing random-address 512MB data blocks. We performed this test using IOMeter. In the diagrams below blue marks the results that comply with the ReadyBoost requirements and pink marks the results that do not comply with them.
The poor results of the Apacer drives might be expected because of their rather low performance in the previous tests. The OCZ Rally 2 is quite a disappointment but it already had a very poor result in the read response test.
The Kingston DataTraveler Secure and A-Data PD10 are the best drives in this test.
Five more models join the group of losers in the write speed test. And about ten drives show very modest results, not higher than 3MBps. Compare them to the leaders: the two models from OCZ and one Lexar easily overtook the 12MBps barrier. These are not just good results – the numbers are two times higher than in the random read test!
