WD Green SN350 (PCIe 3.0 NVMe/3,200 MB/s Read/1,500 MB/s Write/Entry-Level Budget NVMe) Review
The WD Green SN350 sits at the entry level of WD's NVMe lineup, using PCIe 3.0 and QLC NAND to offer a genuinely low-cost step up from SATA storage for buyers building or upgrading the most price-sensitive systems.
At up to 3,200 MB/s read and 1,500 MB/s write, this drive's numbers trail the PCIe 4.0 drives elsewhere in this category substantially, but still comfortably beat SATA SSDs for boot and load times at a genuinely entry-level price. Against the WD Blue SA510, covered elsewhere on this site, that SATA drive targets buyers without an available NVMe slot, while this SN350 requires an M.2 NVMe slot to install. Against the WD Blue SN580, also covered elsewhere on this site, that PCIe 4.0 drive delivers substantially higher speed at a moderately higher price.

Best for
- Budget builders who want the lowest-cost NVMe upgrade available for a basic system. This drive delivers a genuine step up from SATA at entry-level pricing.
Not for
- Not for buyers who want to use their motherboard's full PCIe 4.0 bandwidth. The WD Blue SN580, covered elsewhere on this site, is the appropriate step up for that hardware.
