Getting USB 2.0 speeds strongly suggests that the cables somehow had horrendous signal integrity...
Anyway I grabbed a 3.1 gen2 SSD and plugged it directly into my 16" M1 Pro (Sandisk Extreme), and I got 850 MB/s read/write with his tool.
And that's supposedly one of the exact drives and laptops he tested. So something is going wrong for him, and it's 90% likely to be cables.
- daenney 4y agoIt doesn’t seem particularly likely to be the cables when the same cable plus same external drive but with an Intel Mac results in the expected performance numbers. In your test, did you use a TB4 cable or a USB data cable?
- brigade 4y agoJust because a marginal cable works on one machine doesn't mean it'll work on another. I used a USB cable, but I retested with an active TB4 cable with the same results. And again with a passive TB3 cable to the same results.
