Hello!
I bought a used SSD and try to find some specs, but there is not muich to find about it

Can anyone tell me more info about the NAND (xxnm, manufacturer) and controller (maybe Alcor)?
Think there's two major obstacles in finding that out:
1. The drive has been out since at least 2013 and so the hardware has likely been changed at least once so even if you could find a review or someone opening up their drive doesn't mean your drive will use the same hardware.
Actually, I recently talked with someone about how the SanDisk Ultra II has changed since its release going from using 19nm TLC NAND along with a controller lacking native support for TLC NAND to 15nm TLC NAND paired with a Marvell controller supporting even QLC NAND.
And that's what is easy to tell has changed - for example the first revision had a lot of spare NAND for ECC and an SLC-cache two to three times that of the 850 EVO.
Seeing as noone is about to review SanDisk Ultra II this long after release who knows if that's true nowadays (kind of doubt it has that much NAND reserved for ECC any longer at any rate).
2. Since the hardware specifications are not very specific it may likely be a similar situation as with Silicon Power where the controller and NAND may vary from drive to drive depending on what they can get a good deal on.
You could try installing Hard Disk Sentinel or SSD-Z to check if they have it in either of their databases but most likely you're not going to find out what kind of hardware's inside short of opening up the drive to check.
