That’s still theoretical speeds, I doubt any drive will be that fast.
Device ships with good emmc storage, it’s all pretty dire. The surface go my friend has got about 150MBps writes and 250 reads. That’s what I’d expect from a “good” emmc machine. I bought some $100 Walmart special a year ago and it gets like maybe 150 reads and 50 writes. Hard drives are fast than this.
Some USB drives are actually pretty good. I have a drive that sustains over 350MBps reads and 150 writes, and bursts almost up to full 400MBps.
That that drive is the exception, not the norm. Those micro center flash drives with white labels? You may get 1 gig of writes in before they crater to 20MBps or less. And the newer black ones? I’ve seen single digit MBps transfers. Putting an OS on there is suffering. Shit just writing the iso on there is bad.
Emmc will be consistently mediocre. If OP had an EMMC laptop then I’m going to guess they didn’t pay extra for a fancy flash drive so the experience is going to be DIRE. If you want to play with the live environment it’s fine.
