This cable has been added to my collection of non-TRIM USB SATA cables. Although I know of a manufacturer that claims to make a TRIM compatible cable, it is too long for my needs. I have yet to find a short cable like this that is TRIM compatible. What is the problem with USB to SATA cable manufacturers still making cables that are not TRIM compliant? It's 2021, not 2008. Tired of not being able to find TRIM compatible cables hence the one star rating! Edit: A few weeks after I asked if this cable was TRIM compatible, the seller replied that the claim was. Again it wasn't. The seller also claimed to have an Asmedia ASM 1153E chip. The one I received has an ASM1051E chip.
