Fast reads, slow writes
One of the lowest prices on 64GB USB drives, at least at the time I got it. Overall good value for low-write, high-read workloads. I would not recommend for a write-heavy workload.
15 MB/sec reads; Physically robust; It's the slide kind with no cover to lose; Read performance from iostat: Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sdh 3591.10 0.00 226.40 0.00 15258.40 0.00 134.79 3.62 15.98 15.98 0.00 4.42 100.00 sdh 3588.60...
