Should have at least a 1.75 MB/sec throughput for 1 MB random writes.Īs you understand, older and over-used devices often cannot meet these requirements, especially on the issue of read and write speeds – essentially, a USB flash drive does have a limit of read and writes in its life, after which its performance significantly deteriorates.

Should have abilities of at least a 2.5 MB/sec throughput for 4 KB random reads.

It should have an access time of 1 ms or less.The flash key should be at least 256 MB in size, with at least 64 KB of free space.

This is what you will see when you try to enable Readyboost on a slow or old device.īefore even running the test, you might be able to get an idea by checking the system requirements of Readyboost:
