The WD Black SN8100 from SanDisk is the company's first NVMe Gen5 SSD, and it promises speeds faster than most drives on the market today.

This SSD is designed to deliver top-notch performance and handle everyday tasks, gaming, and heavy workloads. We look at what it can do, how well it works, and how it stacks up against other high-end SSDs.

Gaming and Real-World Load Performance

The SN8100 really shines in games and heavy-use situations in real life. Benchmarks that simulate installing games, loading times, moving big game folders, and recording gameplay show that it performs much better than its competitors. As it turns out, it's about 25% faster than any other SSD we tried in this category.

When it comes to the things gamers care about most—loading games, updating titles, and adding new content—the SN8100 not only does better than average, but also takes the lead.

Gen5 drives that came before were only 20% to 25% faster than the fastest Gen4 drives, like the Crucial T500. The SN8100, on the other hand, is 59% faster than the T500 and 27% faster than the fastest Gen5 rival.

Sequential Read/Write and Console Considerations

Sequential read and write speeds don't always show how fast something will work in real life, but they can still show you how fast something can work at its fastest. When it comes to sequential writes, the SN8100 just edges out the Samsung 9100Pro. But when it comes to sequential reads, the SN8100 and the 9100Pro are tied for first place.

For PlayStation 5 users, the SN8100 reads faster than the system needs. However, buying this high-end Gen5 SSD for the PlayStation5 isn't the best idea right now since it doesn't support PCIe Gen5 speed. A Gen4 SSD with solid DRAM is still a cheaper way to store data on a computer.

Light-Duty and Everyday Use Performance

The SN8100 is the best you can get for everyday tasks like working with documents, browsing photos, and launching software. In the PCMark10 Quick test, which simulates typical light use, most Gen5 drives achieve around 1000 MB/s. They are beaten by about 10% by the SN8100, which makes it faster for everyday PC work.

Heavy-Duty Workloads and OS Performance

When you test with the full PCMark10 suite, you can simulate more demanding use, such as using the OS and programs like video editing. In this case, too, the SN8100 shines, achieving almost 1200MB/s compared to competing high-end SSDs' 1000MB/s.

The SN8100 is the first Gen5 drive to offer a noticeable improvement in extended heavy-use performance. Latency stays competitive.

Thermal Efficiency and Cooling

One great thing about the SN8100 is that it uses very little power—only 7W, compared to Gen5 drives that draw more. But good cooling is still very important.

Without a fan, even very good drives will get hot under heavy load, slowing them down. Using a heatsink that comes with the motherboard or a third-party heatsink guarantees steady performance and long life.

Design, Specifications, and Controller Details

At launch, the WD Black SN8100 comes in 1TB, 2TB, and 4TB capacities. Later, versions with heatsinks and 8TB capacities will be offered. The tested 2TB type is single-sided, as you'd expect for other sizes as well.

SanDisk uses TLC NAND and a DRAM cache. Each 1TB drive is estimated to last 600TBW and comes with a 5-year warranty. It supports TCG Opal encryption. The controller is a modified SMI2508, but SanDisk hasn't said what was changed. The specs sheet isn't very detailed, but the drive's efficiency pretty much speaks for itself.

Consistency and Sustained Stress

Consistency testing mimics very heavy, multi-hour tasks. The SN8100 isn't as good as some Gen5 and high-end Gen4 drives in this area, and it slows down under sustained heavy stress. This means the drive might not work well in places that need to do a lot of work all the time, like database systems.

Pricing and Final Thoughts

There are some things to think about with the WD Black SN8100. Things to keep in mind are that it doesn't work as well under long-term stress and that the specifications aren't completely clear. Nevertheless, it works very well for most people. It regularly beats competitors in games and everyday tasks, and often by a large amount.

When it first came out, the 4TB model cost $550, making it hard to choose over cheaper Gen5 and Gen4 options. Prices are likely to drop quickly and then level off at more fair levels.

Once that happens, the WD Black SN8100 will probably be the best Gen5 SSD on the market. This is one of the best things to buy if you want extreme performance. Keep an eye out for local prices.
