Crucial X6 1TB
Score: 34/100
Transcend Portable SSD 500GB
Score: 57/100Rankings
The Transcend 500 GB portable SSD offers fast 1050 MB/s reads, a feather-light aluminum body and full-disk AES-256 encryption, making it ideal for creators on the go. It includes versatile cables but may warm up and the case feels cheap.
The Crucial X6 1TB is an affordable, ultra-light portable SSD with decent everyday performance, but its QLC NAND and DRAM-less architecture prevent it from delivering the high sustained speeds some users expect.

Professional reviewers consider the X6 a serviceable, budget-friendly portable SSD that works well for everyday tasks but is hampered by its SATA-based internals and DRAM-less design, recommending PCIe-based alternatives for power users.
Consumers appreciate the X6's reliability, pocket-size convenience, and price, though many note that real-world speeds fall short of the advertised 800 MB/s and that performance drops after the cache is exhausted.
