I have a thin client with a 32 GB USB flash drive and a 512 MB IDE "disk on module" (DOM).

I successfully used the following command for the Sysbench program which I think tested just the 32 GB USB flash drive. As you can see, the result is miserably slow even though the flash drive is capable of write speeds of ~15 MB/S and connected to a USB 2.0 port.

I was hoping I would be able to test the 512 MB IDE DOM to see if that's much faster.

I'm using antiX 16.2

Code: Select all

Have you put this to the Antix forum?

No but I think they're getting fed up of me over there and this seems like something that would be the same for both distributions.
