The WD Green SN350. It is rated up to 3200 MB/s read and 2500 MB/s write, against 530 MB/s read and 430 MB/s write for the MS30.

Will the SN350 fit my old laptop?

Only if the laptop's M.2 slot supports NVMe. Many older machines run SATA-only M.2 slots, and there the MS30 is the one that works.

Is the SN350 worth the extra money?

For a machine with an NVMe slot, yes. At $119.99 at Newegg as of November 7, 2026, it costs about $38 more than the MS30's $82.30 as of November 3, 2026, and is several times faster.

Neither listing gives an endurance rating in TBW, so compare the manufacturer's TBW figures for the exact capacities before buying. The SN350's DRAM-less design can also slow on long sustained writes.

Does either drive have hardware encryption?

No. The MS30 lists no built-in encryption, and the SN350 lists only a cloud storage tie-in, so use software encryption such as BitLocker if you need it.

Which is better for gaming?

The SN350, because faster NVMe reads cut level load times. The MS30 still works for games but is limited by SATA bandwidth.

Team Group MS30 M.2 SATA SSD vs WD Green SN350 NVMe SSD

Buy the WD Green SN350 for any machine with an NVMe slot: it reads at up to 3200 MB/s and writes at up to 2500 MB/s, roughly six times the MS30's 530/430 MB/s. The MS30 is the fallback for older laptops and boards that only take a SATA M.2 drive. On price, the SN350 is $119.99 at Newegg as of November 7, 2026, against $82.30 for the MS30 as of November 3, 2026, so the speed costs about $38 more.
