All consumer 2.5" Seagate and WD drive >500GB are SMR.
Except older ones.
Most if not all of them are fake cards with real recycled components. They take broken server boards with soldered HBA chips and put them onto a new fake PCB, then sell it back to you. Same thing is true with network cards
I've heard that overheating is more of an issue with the SAS 12Gbit HBAs, not the older 6Git ones like yours
Mine work well as external drives. Keep in mind that according to the datasheet these are not designed for 24/7 runtime, people who tried that had failures
Technically not native USB, they usually have a SATA to USB translator chip soldered
With your logic we would not have recertified drives.
They also have the scummiest tactics.
Did they recall those broken by design external SSDs, or are they still trying to sell them and to blame it on the Sandisk brand?
