a lot of the 2.5'' ones have a usb connector on the pcb for the drive itself.
wd was known for this.
the only ones that don't are 3.5 inch drives but most of the enclosures, if dead will not let you get your data back.
some of the pcbs that attaches to the drives sata connector encrypts the data
Best bet is buying an enclosure and drive separately. Depending on what you're using it for (ex: backups) a drive dock is nice to have too.
Are there any external drive makers that still use a regular 2.5" SATA drive inside the enclosure?

i had a couple of 2.5" WD drives that i took apart - it looked like the USB PCB board was one pc with the drive, but it wasn't - there was a pc of metal tape that covered the joint - tuff to peel off but it revealed a std sata connection on the drive
economically it doesn't make sense to mfgr drives with a different connection for the small qty going to external drives
Seagate Expansions (mobile) definitely do. OWC shells and sells a ton of 2TB 2.5" Samsung drives from those (and sells the shells as well).
Thanks.
P.S. I checked over at OtherWorldComputing and I could not find the shells for sale. Maybe they stopped doing this?
