At CES 2025, Adata introduced a number of new storage products, including the Adata XPG SE940, a portable SSD that marks the first time Adata uses USB 4 technology.
Adata also touts the SE940 as the smallest USB 4 external SSD commercially available.
It can reach speeds of up to 4,000 MB/s for reading and writing data. This makes it not only the fastest portable SSD in Adata’s line-up, but also a contender in the wider external storage market.

The SE940 uses a modern single-chip controller from Silicon Motion, which provides stable performance, uses power efficiently and works smoothly.
It also has a built-in fingerprint reader and comes with storage options of up to 8TB, providing plenty of space for large files, multimedia work or backups.

The company also announced the SR800 and SR820, portable SSDs that offer up to 20GB speeds, USB 3.2 Gen 2 and up to 4TB capacity.
