Searching for this reveals that this thing claims to be based on a Silicon Motion SM2263EN controller (used by countless OEMs like Fanxiang, Kingston, Kingchuxing and whoever else). While I personally would never buy from those OEM brands slapping together 3rd party NAND flash and 3rd party SSD controllers (Kingston included) maybe that’s a legit drive.
Now you know that this thing gets dog slow with continuous writes even if the usual hdparm BS shows way higher numbers.
But did you execute f3read as well? Since that’s the verify step to ensure your flash devices doesn’t show a fake capacity…
