Which of the 2 above is better?
If you want to take a drive out of a Thinkpad and place it in an external enclosure, without doing anything to it, then the one I referenced is "better". If you want to place a drive which does NOT have the Lenovo-specific add-on connector (which is pre-attached "permanently" to Lenovo drives, but which can be removed, but not intended to be removed!) then the first adapter above is "better".
The connectors on these drives are "standard", but most laptop manufacturers, including Lenovo, use a proprietary connector, and they attach a small mapping connector/cable to the drive so that the drive mates with their proprietary connector. The proprietary connector appears attached "permanently" to the drive, and to remove that connector sometimes one needs to undo tape and screws which were not meant to be undone. Such is the case with Lenovo's drives, also. The two enclosures above accept either the "virgin" drive's connector or the Lenovo-specific connector on Lenovo's drives.
