I personally use my external HDDs without enclosures. I.e. I use a USB<->SATA adapter (e.g. https://www.dx.com/p/usb-3-0-to-sata-22-pin-2-5-hard-disk-driver-adapter-cable-black-18cm-2021357) and then connect the "raw drives". The advantage is that the same adapter cable works for various sizes of drives (e.g. I have some extra-thick 2½" 2TB drives which don't fit in a normal 2½" enclosure). Some of those adapters can also be used with 3½" drives (at the cost of extra work to power the drive, and I'm not sure it's worth the trouble: I personally stopped using 3½" disks when the 2½" disks crossed the 2TB threshold).
