Western Digital WD Green SN350 1TB PCIe 4.0 x4 NVMe M.2 2280

The WD Green SN350 is a budget NVMe drive that crushes SATA speeds for everyday use. It scores 85.6 for budget value, making it a great cheap upgrade for older machines. Just know it's QLC, so sustained writes and endurance aren't its strong suits.

Sequential reads top out at 3,200 MB/s and writes at 3,000 MB/s. That's solidly middle of the pack in our speed rankings, and roughly four times faster than a typical SATA drive. But the QLC NAND means sustained writes can slow down once the cache fills up. For booting Windows, loading apps, and general web browsing, you won't notice that limitation. For moving huge video files around all day, you will. Endurance lands below average too, so this isn't the drive for heavy write workloads.

Stacked against the Samsung 990 PRO, Crucial T500, or Lexar NM1090 PRO, this drive gets smoked on raw speed. Those are PCIe 4.0 monsters with TLC NAND and much higher endurance. But they also cost significantly more. The SN350 isn't competing with them. It's competing with SATA SSDs and old hard drives. Against those, it wins easily. The MSI SPATIUM M480 PRO and XPG GAMMIX S70 Blade sit in between, offering better performance than the SN350 without the premium price of the Samsung or Crucial. If you can stretch your budget a bit, those are worth a look.

Pricing is all over the place right now. We're seeing USD 150 to USD 249 across three US listings, which is a USD 99 spread. That's wild for a budget drive. At the low end, it's a steal. At the high end, you're getting into territory where faster TLC drives start to look tempting. Shop around before you buy. The cheapest listing in our data is the one to grab if you can find it.

The WD Green SN350 is a budget NVMe drive aimed at breathing life into older machines. It's not chasing benchmark glory, but it promises a big jump over any SATA SSD for everyday tasks. With 1TB of QLC NAND and a 3-year warranty, it's a simple, low-risk upgrade for the right person.

Our database puts it at 55.9 out of 100 overall, which sounds rough until you see the budget score: 85.6. That tells the whole story. This drive is a value play, not a performance monster. If you're still booting from a spinning hard drive or an old SATA SSD, this will feel transformative.

Skip this if you regularly move large files, edit video, or run workloads that hammer the drive with sustained writes. The QLC NAND and below-average endurance will frustrate you. Content creators and heavy gamers should look at TLC drives like the Crucial T500 or XPG GAMMIX S70 Blade instead.

Buy this if you have an older PC or laptop with an NVMe slot and you just want it to feel snappy again. It's perfect for students, casual users, and anyone who mostly browses, streams, and does light productivity work. The 3-year warranty and WD's reputation add peace of mind. Just don't expect it to keep up with high-end drives under heavy sustained loads.
