Re: why is thumb drive so slow?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I would download and use DiskSpeed32 to test the actual
throughput on the Flash drive.

Download here:

For example, My MiniCruzer 256

(Optimized for Quick Removal -- No Write Cache)
Access Time ~7.5 Ms
Throughput ~6.2 Meg-per-Second

(Optimized for Performance -- Write Cache Enabled)
Access Time ~7.5 Ms
Throughput ~6.6 Meg-per-Second
