I work with large media files (MOV, MXF, EXR Sequences etc.) a lot and last year I needed fast and portable storage for my laptop. I bought a Transcend ESD380C Portable 2TB because it's rugged, fast and got mostly positive reviews.
I successfully used it abroad and could work without a hitch. It felt just like an internal NVME SSD and the 4.6k movies ran like butter.
Now I had to revisit the project again and noticed that while the write speeds were as fast as before, the read speeds plummeted.. A LOT.
Doing a sudo hdparm -tT /dev/sda gives me this:
Code: Select all
/dev/sda:
Timing cached reads: 28746 MB in 2.00 seconds = 14399.40 MB/sec
Timing buffered disk reads: 42 MB in 3.01 seconds = 13.97 MB/secI tried different kernels, different cables. The drive is super fast (both read and write) when connected to another laptop and I have no idea where this could come from.
