[quote=”lilpyro” post=544]so they don’t accidently get hit by a flying drum stick or being bumped into since those flash drives stick out a little from the front of the U24 in the rack mount[/quote]
You might take a look at the Kingston DataTraveler drives. Pretty low profile. I’d trust this before trusting a dongle flapping around the front of the rack unit. I think you can get these up to 256 GB now.
Consistent playback will have nothing to do with the physical size of the drive. It will have everything to do with whether the drive consistently responds to read requests in a timely fashion, and you’ll only be able to determine that by testing. I am guessing this drive would work fine for playback.
