Rating: 5/5 Purchased to replace older Firewire/USB Pro Mini January 24, 2020 My 3+ year old OWC Mercury Elite Pro mini had a bad USB Micro-B jack failed due to everyday use while traveling. After calling support it was determined that preparing was not an option and it was out of warranty. Used it with the firewire for several months then purchased the NEW USB-C case. Inserted my old 2 TB drive and it works great. Way faster than my other drives. It was also the only case I could find that fit my 14.5mm high 2TB HD. Happy with the new disappointed that the old one could not be repaired.

Rating: 4/5 Nice, solid case with quality cables June 28, 2019 I’ve tried a number of enclosures, and this one is the best I’ve found so far to house an SSD. Easy to install the drive, very solid case. I would have gone 5 stars, but one of the closure screws was stripped, so down a star for that. The back plate still secured fine, so not a big deal.
