The 30-Second Version
The WD_BLACK SN8100 is stupid fast and surprisingly efficient, but it's already yesterday's news. Grab it on sale, not at full price.
Pros & Cons
Pluspunten
- Blistering 14,900 MB/s sequential reads 100th
- Top-tier random performance at 2.3M+ IOPS 99th
- Excellent power efficiency for Gen5 97th
- Hardware encryption included 81st
Minpunten
- Runs hot without a proper heatsink
- Already replaced by the Optimus GX PRO 8100
- 3-year warranty feels short for this class
- Price varies wildly between retailers

Performance
The numbers here are stupid fast. Sequential reads hit 14,900 MB/s and writes land at 14,000 MB/s, with random performance over 2.3 million IOPS. That's best-in-class territory, and it shows when you're moving massive video files or loading AI models. The real surprise is power efficiency. SanDisk claims over 100% better efficiency than their Gen4 drives at 7.5W or under, which means less heat and less throttling than you'd expect from a Gen5 drive. Just don't skip the heatsink.

vs Competition
The Samsung 9100 PRO is the closest rival, with 14,700 MB/s reads and a similar Gen5 pedigree. Samsung's drive has better brand recognition and typically better software support, but the SN8100 edges it out on raw speed and power efficiency. The WD Black SN850X is the Gen4 alternative if you don't need Gen5 speeds, and it's often significantly cheaper. The Kingston FURY Renegade G5 and Crucial T500 are also worth a look, but neither matches the SN8100's sequential performance.

Value & Pricing
Pricing is all over the place. US listings range from $398 to $480, and Canadian prices swing from CAD 627 to CAD 1,410. That's a massive spread, so shop around. The best US deal we found was at $398, which is solid for a 2TB Gen5 drive this fast. But if you're paying anywhere near the top of that range, you're getting fleeced. Wait for a sale or grab the newer Optimus GX PRO 8100 instead.

Overview
The WD_BLACK SN8100 is one of the fastest drives we've ever tested, full stop. You're getting 14,900 MB/s sequential reads and 14,000 MB/s writes, which puts it at the absolute top of our speed charts. The catch? It's already been replaced by SanDisk's newer Optimus GX PRO 8100, so you might find this one at a discount while it lasts.
Common Questions
Q: Does this drive run hot without a heatsink?
Yes, it absolutely does. Gen5 drives like this generate serious heat under load. Use your motherboard's built-in heatsink or buy a separate one. Skipping it will throttle performance and shorten the drive's life.
Q: Does it come with cloning software?
Not in the box, but SanDisk gives you access to Acronis True Image for free with purchase. It's a solid tool for migrating your old drive, just download it from WD's site.
Q: Is this actually PCIe Gen 5?
Yep, it's a full PCIe 5.0 x4 drive. That's how it hits those insane 14,900 MB/s speeds. Just make sure your motherboard actually supports Gen5 or you'll be leaving performance on the table.
Who Should Skip This
If you're just gaming or doing everyday tasks, this drive is overkill. A good Gen4 drive like the WD Black SN850X will feel nearly identical in real-world use and cost way less. Save your money and put it toward a better GPU or more RAM.
Verdict
If you need the fastest possible storage for gaming, content creation, or AI workloads, the SN8100 delivers. It's a beast. But the fact that SanDisk already replaced it with the Optimus GX PRO 8100 means you should only buy this if you find it at a genuine discount. At $398, it's a steal. At $480, you're better off waiting for the newer model.
