Western Digital WD Green SN350

The WD Green SN350 is a 2TB budget NVMe drive that's genuinely cheap at $240 to $269, with Best Buy usually offering the best price. It hits 3,200 MB/s reads and writes, which is fine for PCIe 3.0 and a huge upgrade over SATA. The catch is QLC NAND with only 100 TBW endurance, so it's best for light daily use, not heavy workloads. If you're reviving an old laptop on a budget, it's a solid pick. If you need endurance and speed, spend more on a Gen4 drive.

Let's talk numbers. The SN350 is rated for 3,200 MB/s sequential reads and 3,200 MB/s sequential writes. That's about four times faster than a SATA SSD, which is the comparison WD loves to make, and it's true. If you're coming from a hard drive or even an older SATA SSD, this will feel like a rocket. Boot times drop, apps open instantly, file transfers that used to take minutes take seconds. The random performance is rated at 500K IOPS read and 450K IOPS write, which lands it at 84th percentile for random performance. That's actually the drive's strongest showing, and it means everyday tasks like launching programs and loading browser tabs will feel responsive.

But here's the thing: the speed score overall is only 57th percentile. That's middle of the pack, and it's because the sequential numbers, while fine for PCIe 3.0, are nowhere near what modern Gen4 drives can do. A drive like the Samsung 9100 PRO or Crucial T710 will absolutely smoke this thing in sustained transfers. The QLC NAND also means write speeds can tank once the SLC cache fills up. One reviewer mentioned sustained writes over 1 GB/s, which is good, but that's likely within the cache window. Push it hard with a big file transfer and you'll probably see speeds drop off a cliff. For the intended use case, light daily computing, it's fine. For video editing or constant large file moves, it's the wrong tool.

The SN350's main competition at this price point is other budget QLC drives, but the data we have shows it going up against some heavy hitters. The Samsung 9100 PRO is a Gen5 monster with endurance ratings that make the SN350 look like a flash drive. It also costs significantly more. The Micron T710 and Crucial T710 are both Gen4 drives that offer much better sustained performance and higher TBW ratings. If you're doing any kind of content creation, running virtual machines, or just want a drive that won't slow down under load, those are better choices.

The Lexar NM1090 PRO and ADATA GAMMIX S70 Blade are also in the mix, and both offer better speed and endurance than the SN350. The trade-off is always price. The SN350 undercuts all of them on cost per gigabyte, and for a lot of people that's the only number that matters. If your workload is web browsing, email, streaming, and maybe some light gaming, you won't notice the difference between this and a drive that costs twice as much. If you're moving large files around constantly or running a database, you absolutely will.

Here's where things get interesting. The SN350 2TB is listed between $240 and $269 across four US listings, with Best Buy typically at the lower end of that range. That's a $29 spread, which is worth paying attention to. If you're buying this drive, check Best Buy first. They're usually the cheapest option and they'll price match if you find it lower elsewhere.

For 2TB of NVMe storage, $240 is genuinely cheap. You're paying about 12 cents per gigabyte, which is budget territory for sure. But the value equation gets murky when you look at what the competition offers. The Samsung 9100 PRO, Micron T710, and Crucial T710 are all Gen4 or Gen5 drives with dramatically better endurance and speed. They also cost more, sometimes a lot more. If you need 2TB and you're on a strict budget, the SN350 makes sense. If you can stretch your budget by $50 to $100, you'll get a drive that's faster and will last longer. The 100 TBW endurance rating means this drive is rated to write its full capacity 50 times over its lifetime. That's fine for light use, but it's half what some competitors offer.

The WD Green SN350 is Western Digital's budget play for anyone still nursing an old laptop or desktop along on a spinning hard drive. It's a 2TB M.2 2280 NVMe drive that promises up to 3,200 MB/s reads and writes, which sounds impressive until you remember we're talking PCIe 3.0 here, not the newer Gen4 or Gen5 stuff. But for the target audience, that's kind of the point. You're not building a benchmark queen, you're trying to make a five year old machine feel snappy again without spending more than the laptop is worth.

Who's this for? Students, casual users, maybe someone running a home server or Plex box who needs cheap, quiet storage. The 2TB capacity is the real draw here. At 78th percentile for capacity, you're getting a lot of room for the money. The drive uses QLC NAND, which is the budget stuff, and that shows up in the endurance rating. 100 TBW is not a lot, but for daily web browsing, document editing, and streaming, it'll last years.

What makes it interesting is the price-to-capacity ratio. You can find this drive for between $240 and $269 in the US, and for 2TB of NVMe storage that's genuinely cheap. The catch is you're giving up speed, endurance, and features to get there. The feature score sits at a sad 15th percentile, and social proof is basically nonexistent at 7th percentile. This is a drive you buy because it's cheap and big, not because anyone's raving about it.

If you're a content creator, skip this drive. Video editors, photographers, and anyone who regularly moves large files will hit the endurance ceiling and the QLC write speed cliff faster than they'd like. The 100 TBW rating is half what you'd get from a decent TLC drive, and sustained writes will slow down dramatically once the SLC cache is exhausted. Look at the Crucial T710 or Micron T710 instead, both of which offer better endurance and faster sustained performance for not much more money.

Gamers who care about load times should also look elsewhere. While the SN350 will load games faster than a hard drive, it's not going to keep up with Gen4 drives in titles that stream lots of data. The Samsung 9100 PRO or ADATA GAMMIX S70 Blade are better choices if you want your games to load as fast as possible. And if you're building a new system with a Gen4 or Gen5 motherboard, buying a PCIe 3.0 drive means leaving performance on the table from day one.

For the casual user, the SN350 is a solid buy. If you've got an older laptop with a spinning hard drive and you want to make it feel new again, this drive will do exactly that. The 2TB capacity means you won't have to juggle files, and the random performance is good enough that everyday tasks feel snappy. At $240 from Best Buy, it's a cheap upgrade that'll breathe years of life into an aging machine.

For anyone doing serious work, look elsewhere. The 100 TBW endurance rating is a real limitation if you're writing lots of data. Video editors, photographers, developers running local databases, anyone who moves large files regularly should spend the extra money on a drive with better endurance and faster sustained writes. The SN350 is a budget drive, and it performs like one. That's not a knock, it's just the reality. Know what you're buying and what you're giving up.
