does it work with USBs? in the free version in Recuva Posted December 16, 2019 I was thinking more about whether the USB software supported the TRIM command. TRIM is a SATA command, and USB protocal isn't. I have read that later USB software can support TRIM, but it's all a bit hazy. TRIM is becoming less relevant now, as the trend in SSDs is towards foreground garbage collection.
