Adata SE880 Portable SSD vs SanDisk Select Portable SSD 1TB

The Adata SE880 is the faster drive by a wide margin: USB 3.2 Gen 2x2 and a PCIe 3.0 x4 NVMe design rated at 2000 MB/s read and write, versus 600 MB/s read on the SanDisk Select. The SanDisk is the simpler, more mainstream pick with a 1TB capacity and a 10Gbps USB-C interface that works on any modern port. Buy the Adata for moving large game and video files fast; buy the SanDisk for light backups and everyday file transfers where 600 MB/s is enough. Neither drive is rated for dust or water resistance, so treat both as desk drives.

• Choose the Adata SE880 if you move big files often, run games from an external drive, or have a USB 3.2 Gen 2x2 port that can feed its full speed.
• Choose the SanDisk Select if you want a straightforward 1TB USB-C SSD for backups and documents and do not need Gen 2x2 throughput.
