Question Building a PC for wiping drives for my side business... are any of the PCIE 5.0 M.2 adapters better than any of the others?

So, I will actually use the full bandwidth of the PCIE 5.0 NVME M.2 adapter when I am wiping four M.2 drives, so is there one that is better another? I'd assume that heat dissipation would be the main difference. Asus has one that looks to vent the heat pretty well. Icy Dock has a fan, and looks easier to swap out drives.

cooling is essential for such a task
with "low" price adapters, the motherboard needs to have the feature "bifurcation". Usually latest thread ripper or Xeon CPU based motherboards are offering this.

Icy Dock would be my personal favorite, but it´s just a feeling maybe they are good in marketing.

Please define "wiping". I have an ASUS motherboard that includes a Secure Erase function in the bios Tool menu. It only takes a few seconds to wipe a 2TB m.2. Since its not an extended process heat does not seem to be an issue. How long do you think your methodology will take to wipe an m.2 drive? If it takes more than a few seconds then I guess you could worry about heat.

but the time won´t be seconds if it´s a real secure erase, I assume about 2minutes per Tb
a few seconds would be deleting the encryption key only, which could be recovered again somehow

LOL.

yeah, that is not wiping the drive. That is just removing the partition table so that Windows will not be able to access the data that is on the drive, but the data is still there. With the right software, the data can still be accessed, read, copied.... everything.

Windows drive formatting is essentially the same thing. It just rewrites the file structure, it does not actually erase data.

Depends on the algorithm and the bus. Basic 1's, 0's, or random is about 10 mins per TB over USB 3. NSA is hours. Peter Guttman is days.
