SanDisk 2TB SSD NVMe

The WD_BLACK SN7100 is a top-tier Gen 4 SSD with 7,250 MB/s reads and excellent random performance. It's a great upgrade for laptops, handhelds, and PS5s, but you'll need to buy a heatsink separately. Shop around, US prices swing from USD 276 to USD 350 for the same drive.

This thing is quick. Sequential reads land at 7,250 MB/s and writes at 6,900 MB/s, which is right up there with the best Gen 4 drives we've tracked. Random performance is no slouch either, 1,000K read IOPS and 1,400K write IOPS put it in the 96th percentile for random workloads. That translates to snappy game loads and fast file transfers. The DRAM-less controller doesn't seem to hurt here, WD's SN7100 controller handles things well. Endurance is solid at 1,200 TBW, enough for years of heavy use. The only real knock is that sustained heavy writes might dip a bit without DRAM, but for gaming and everyday use you won't notice.

Against the Samsung 990 Pro and WD's own SN850X, the SN7100 holds its own on raw speed. The 990 Pro edges it out slightly in sustained workloads thanks to DRAM, but the SN7100 counters with better power efficiency, which matters in laptops and handhelds. The Crucial T500 is a closer match on price and performance, though the SN7100's random write numbers are stronger. The Kingston Fury Renegade and Lexar NM1090 PRO are both solid alternatives, but neither matches the SN7100's combination of speed and endurance in this form factor. If you need the absolute fastest sustained performance, the 990 Pro or SN850X are still the safer picks. For most gamers, the SN7100 gets you 95% of the way there.

Pricing is all over the place depending on where you shop. In the US you'll see it listed anywhere from USD 276 to USD 350, and in Canada the spread is even wider at CAD 410 to CAD 590. That's a huge gap for the same drive. If you're buying in the US, the lower end of that range makes this a strong deal for a top-tier Gen 4 drive. At the high end, you're paying a premium for the WD_BLACK branding. Shop around before you commit, the best US price we're seeing is USD 276, and paying USD 350 for the same silicon would sting.

The WD_BLACK SN7100 is a 2TB PCIe 4.0 drive aimed squarely at gamers who want fast load times without melting their laptop. It hits 7,250 MB/s read and 6,900 MB/s write, which puts it in the top tier of Gen 4 drives in our database. The DRAM-less design keeps power draw low, and WD backs it with a 5-year warranty and 1,200 TBW endurance.

Setup is basically plug and play, and owners seem genuinely happy with it. The main gripes are the price and the fact that you don't get a heatsink in the box. If you're tossing this into a PS5 or a tight laptop bay, plan on grabbing one separately.

Skip this if you're building a desktop workstation that hammers the drive with sustained large file transfers. The DRAM-less design means the Samsung 990 Pro or WD SN850X will hold up better under constant heavy writes. Also skip it if you're on a tight budget, the affordability percentile is mediocre and there are cheaper Gen 4 drives that get you most of the way there for less cash.

If you're running a laptop, gaming handheld, or PS5 and want a fast 2TB upgrade, the SN7100 is an easy recommendation. It's fast, reliable, and backed by a solid warranty. Just budget for a heatsink if your system needs one. Desktop users with room for a DRAM-equipped drive might find better sustained performance elsewhere, but for the target use case this drive nails it.
