The ROG Strix Arion and the TUF Gaming A1 are two portable SSDs with very similar performance, and, in fact, the choice is limited to the aesthetics and endurance factor. The ROG Strix Arion is more compact, lighter and offers Aura Sync-compatible RGB lighting. The TUF Gaming A1, on the other hand, is a tad bulkier, costs less, and offers greater durability thanks to military certification and waterproofing.
