--- Comment #94 from blaasdf <[email protected]> --- > Else you risk that flash areas needs to be erased before they can be written, > which takes additional time. Are you talking about write amplification? That's a very good point, I totally forgot about that and no, I didn't wipe the drive before each attempt. Although I suspect the problem occurs when attaching the drive, that's what made me think the problem is with the usb driver. What I mean by that is that once I connect the disk and see the message: ``` da0: 40.000MB/s transfers ``` the disc won't write at higher than 40MB/s rates. So I thought that during the init sequence the usb driver "negotiates the protocol version to use" and that's what's being used afterwards. I might be totally wrong here and this might be unrelated. Just wanted to share what I found in case it pushes things forward ;) -- You are receiving this mail because: You are the assignee for the bug.
