Pros & Cons
Pros
- ✓ Mounts a 3.5in HDD and a 2.5in SSD in one 5.25in bay simultaneously
- ✓ Works with IDE, SATA, and SAS drives, so retro and modern builds both fit
- ✓ Swap the 2.5in slot for an 80mm fan when you only need one drive
- ✓ Ships with 12 mounting screws, no extra hardware run needed
Cons
- ✗ Plastic body flexes more than steel caddies under a loaded 3.5in drive
- ✗ No vibration-damping grommets, so 7200RPM drives transmit hum to the case
- ✗ 2.5in drive must be installed first, forcing a rebuild to add one later
- ✗ Fan slot and 2.5in bay share space, you get one or the other
