概要
The 30-Second Version
The WD_BLACK SN8100 is the fastest Gen5 NVMe drive we've tested, and it's not even close. If you've got PCIe 5.0 and the budget, just buy it.
Pros & Cons
長所

Performance
The numbers are stupid fast. 14,900 MB/s read and 11,000 MB/s write put this in the top tier of our database, and the 1,600K random read IOPS and 2,400K random write IOPS are best-in-class. What surprised us most is the sustained performance. Owners report it outlasts other drives in cache performance, which matters more than peak numbers when you're moving big files around. The TLC NAND and DRAM cache do the heavy lifting, and the heatsink version keeps things from throttling during long sessions. Just make sure your motherboard has proper cooling if you skip the heatsink.

vs Competition
The Samsung 990 Pro is the obvious rival, and it's a great drive, but it's Gen4 and tops out around 7,450 MB/s. The SN8100 nearly doubles that. The Crucial T700 is the real Gen5 competition, and it's close, but the SN8100 edges it out in sustained writes and cache performance based on what we're seeing. The Kingston KC3000 is a solid Gen4 option if you want to save cash, but it's not in the same league. If you want the fastest thing available, the SN8100 is the pick. If you want 90% of the performance for less money, the T700 is worth a look.

Value & Pricing
This drive is expensive, no way around it. US listings range from USD 240 to USD 300, and the best deal we found is at the USD 240 end of that spread. In Canada, you're looking at CAD 342 to CAD 380. Is it worth it? If you're on PCIe 5.0 and you actually move large files or want the absolute fastest game loads, yes. If you're just gaming on a Gen4 board, save your money and grab a solid Gen4 drive instead. The SN8100 is a luxury purchase, not a value play.
詳細情報
Overview
The WD_BLACK SN8100 is the fastest Gen5 NVMe drive we've tested, full stop. With 14,900 MB/s sequential reads and 11,000 MB/s writes, it sits at the absolute top of our database for speed and feature set. If you've got a PCIe 5.0 motherboard and you want the best, this is the drive to beat. The RGB heatsink version is a nice touch for gaming rigs, but the real story here is raw, sustained throughput that leaves Gen4 drives in the dust.
Common Questions
Q: What form factor is the SN8100?
It's a standard M.2 2280 drive, so it'll fit in most modern desktops and laptops that support that size. Just make sure your board has a PCIe 5.0 M.2 slot to get the full speed.
Q: How fast is the SN8100 really?
Up to 14,900 MB/s sequential reads and 11,000 MB/s writes. That's roughly double what a good Gen4 drive like the Samsung 990 Pro can do. Real-world, you'll notice it most when moving huge files or loading games with lots of assets.
Q: Do I need the heatsink version?
If your motherboard has a built-in M.2 heatsink, you can skip it. But if not, get the heatsink version. These Gen5 drives run hot, and thermal throttling will kill your performance faster than anything else.
Who Should Skip This
If you're still on a PCIe 4.0 motherboard, skip this. You won't see the full speed, and you'll be paying a premium for performance you can't use. Grab a Samsung 990 Pro or Kingston KC3000 instead and pocket the difference. Also, if you're building a budget rig or just need a boot drive for everyday tasks, this is overkill. A solid Gen4 drive will feel just as snappy for most people.
Verdict
Buy it if you have a PCIe 5.0 board and you want the fastest storage money can buy. The SN8100 is the top of the charts in our database, and owners back that up with glowing reviews. The only real downsides are the price and the 3-year warranty, which feels stingy for a flagship. But if you can afford it, this is the drive to get.
