SATA vs NVMe vs Portable SSD: Choose the Right Connection
Choose an SSD around the host connection and intended use. A 2.5-inch internal bay, an NVMe-capable M.2 socket and an external USB connection require different products.
NM500: an internal 2.5-inch SATA connection
NM500 is a 2.5-inch SATA SSD for compatible drive bays. Confirm the connector, mounting arrangement and clearance before replacing a system drive. Its current capacities are 128 GB, 256 GB, 512 GB and 1 TB. Plan a backup and system installation or migration before replacing your existing storage.
NM800: an NVMe-capable M.2 host
M.2 is a form factor, not a guarantee that a socket supports NVMe. For NM800, check NVMe support, keying, mounting and the supplied dimensions, and request the exact PCIe generation and lane configuration for your host. Its listed capacities are 128 GB, 256 GB, 512 GB and 1 TB.
NM700: external USB-C storage
NM700 uses USB-C / 5 Gb/s with SATA storage. Its capacities are 120 GB, 128 GB, 256 GB, 512 GB and 1 TB. Check the host’s USB data support, a suitable data cable, power and file system. The 5 Gb/s interface figure is not a guaranteed file-copy result.
Compare evidence using the same conditions
NM800 has separate supplied reference benchmarks by capacity. NM500’s displayed performance reference is for 256 GB; its inspection report identifies a separate 128 GB sample. Ask for relevant host and test conditions before comparing results. All three SSD models have a published 3-year warranty.
