Customer Reviews
Back to topThis does exactly what I needed it to do, and does it well, but it uses a power brick that is bigger and heavier than the device itself. That makes it be only marginally satisfactory.
- Reviewer:Reviewer593343368
Thank you for you for sharing your honest feedback with us. We're glad to hear that the MiniStack STX meets your needs and performs well. We also appreciate your input regarding the power bricks size and weight; It's something we take seriously as we strive to improve our products. Please feel free to contact us if you have any further questions, comments, or concerns. https://eshop.macsales.com/Service/
Very versatile , love the combination of SSD and HHD. Many options for real time and backup. I have over 500,000 photo files from over 40 years of work. For security I have offsite backups kept in a safety deposit box as well as a full set of backups on site. No reliance on Cloud or WiFi networks is reassuring. What used to be a chore is now just so much faster! I'll be ordering another two soon to replace those at the bank. Thank you!
I would recommend this product to a friend!

This drive replaced a very old 12TB LaCie drive. The bonus was getting 3 Thunderbolt ports, which I'm using for other devices.
