8 TB hard drive buying guide

Who a 8 TB drive is for

8 TB is a default building block for home NAS and anyone who wants one drive to hold a large Plex or photo archive.

8 TB hard drive vs SSD

Bulk storage usually means HDDs. 8 TB SSDs exist for specialized needs but rarely beat HDD price per TB. Use SSDs elsewhere in the build for apps and transcode cache.

What to look for in a 8 TB drive

Helium-sealed drives reduce power in dense NAS chassis.
Rescue data recovery bundles sometimes ship with retail drives, factor subscription cost.
Surveillance drives optimize write patterns different from NAS, match workload.
Internal 8 TB drives are 3.5-inch. Some desktop USB externals use shingled (SMR) recording, which suits sequential archives better than busy shares.
