Corsair

Corsair EX100U 2TB
8.5/10

A 2TB Gen 2x2 portable SSD in the same aluminum-and-rubber body as the 1TB. Write speed drops slightly to 1800 MB/s on the 2TB variant — a real-world trade-off for the larger NAND die. Still above 2GB/s on long transfers as long as the host is Gen 2x2.

Crucial

Crucial X6 4TB
8.2/10

A 4TB external at the X6's price is closer to spinning-rust economics than to typical SSD pricing. The 800 MB/s cap doesn't matter when the use case is video archive or photo-library cold storage — this drive is bought for capacity first, speed second.
