A German data recovery specialist has confirmed what many Reg readers will have suspected: USB memory sticks are getting less reliable. The cause, as you might have guessed, is inferior memory chips, while the move to storing multiple bits per flash cell also plays a part.
CBL Data Recovery posted that the quality of newer memory components in microSD and USB sticks is declining, and it reported that USB sticks where the NAND manufacturer's logo had been removed from the chip are increasingly turning up in its data recovery laboratory.
It suspects that flash chips from manufacturers such as SK hynix, Sandisk or Samsung that fail quality control checks are being resold into the market, but marked as components with lower memory capacities.
