Recently purchased a used (but in pristine condition) Microsoft Surface Pro 10 for Business for personal use in grad school. (Wanted to be able to draw AND use desktop based applications on the go.) This is the original SSD. It originally came with a little heatsink surrounding it w/ Microsoft branding, but I transferred it to the new SSD. So yes, this one is nakey. Looks like Microsoft slapped their wrapper on a Western Digital/SanDisk. Used the Surface IT Toolkit for a secure erase of the drive. It's blank right now, but if you'd like me to put a Windows 11 .iso or something similar on it before I ship, let me know.
