Choosing a 3.5-inch hard drive enclosure
Plan for external power
A 3.5-inch desktop hard drive needs more power than a USB port normally supplies, so these enclosures use an AC adapter.
Check the capacity claim
Controller and firmware support can place a stated limit on drive capacity. Choose an enclosure that explicitly supports the drive size you plan to install.
Give the drive airflow
Large hard drives can run for hours during backups. Ventilation, an aluminum body or a fan may improve sustained operation in warm rooms.

Frequently asked questions
Can a 3.5-inch enclosure run without its power adapter?
Normally no. The USB connection carries data, while the supplied adapter powers the desktop hard drive.
Can I install a 2.5-inch drive in a 3.5-inch enclosure?
Some models support both sizes, but the listing must state this and the drive should be held securely.
Does an enclosure make an internal drive portable?
It makes the drive externally accessible, but a powered 3.5-inch setup is better described as desktop storage than pocket-portable storage.
Should I use an enclosure or a docking station?
An enclosure protects a drive for regular use. A dock is more convenient when drives are swapped frequently.
