- The SE940 is Adata’s first USB 4 portable SSD
- It reaches a maximum of 4 GBps in read/write
- Expect many more USB 4 external SSDs to appear in 2025
Adata presented at CES 2025 introduced a range of new storage products, including the Adata XPG SE940, a portable SSD that marks the first time Adata has used USB 4 technology.
Adata also calls the SE940 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 not only makes it the fastest portable SSD in Adata’s range, but also a contender in the wider external storage market.
New benchmark for portable SSD performance
The SE940 uses a modern single-chip controller from Silicon Motion, which delivers stable performance, uses energy efficiently and runs smoothly.
It also has an in-display fingerprint reader and comes with storage options of up to 8TB, providing plenty of space for large files, multimedia work or backups.
Adata also announced several other SSDs at CES. The XPG MARS 970 Storm and Blade are Gen 5 M.2 NVMe SSDs (up to 8TB) that offer read speeds up to 14 GB/s and write speeds up to 12 GB/s.
The company also announced the SR800 and SR820, portable SSDs that offer speeds up to 20 GB, USB 3.2 Gen 2, and capacity up to 4 TB.
To round things out, Adata has announced the SDXC SD 8.0 Express memory card that uses PCIe 3.0 x2 for speeds of up to 1600 MB/s reading and 1200 MB/s writing.
