- AI data center demand has tripled drive prices in six months, with 8TB SSDs now selling for more than a new MacBook Air, reshaping the entire external storage market.
- WD Elements desktop drives remain the top backup pick at $280 for 8TB, scoring 120 MB/s sequential writes — a drive the reviewer has used reliably for over a decade across Windows, macOS, and Linux.
- SanDisk G-Drive ArmorATD was newly added as a semi-rugged spinning drive with 3.3ft drop protection, IP54 splash resistance, and a pre-formatted HFS+ file system for plug-and-play Mac Time Machine backups.
- LaCie Rugged Pro5 tested as the fastest drive in the guide at 5,787 MB/s read and 5,188 MB/s write via Thunderbolt 5, but its 4TB price has climbed from $600 to $1,600 in this update cycle.
- Corsair EX400U is the top USB4/Thunderbolt 4 pick at roughly 3,800 MB/s read and 3,550 MB/s write, and uniquely includes a MagSafe connector for backing up ProRes footage directly from an iPhone.
- Crucial X9 Pro tops the portable SSD category for photographers — weighing 1.3 ounces, delivering over 1,050 MB/s symmetrical speeds, and working across Windows, Mac, Linux, Android, and iOS without reformatting.
Why it matters: The AI memory crunch has reshaped consumer storage economics overnight: a $280 WD Elements spinning drive is now the rational backup choice when 8TB SSDs cost more than a MacBook Air, while professionals needing Thunderbolt 5 speed must absorb the LaCie Rugged Pro5's climb from $600 to $1,600 — a near-tripling that signals how deeply data center buildouts are distorting pricing across the entire storage stack.
