SanDisk Extreme Pro M.2 NVMe 3D SSD Review: SanDisk Joins The NVMe Club

The SanDisk Extreme Pro M.2 NVMe 3D SSD is like the hot sister of Western Digital's new enthusiast SSDs. We tested the WD Black SSD recently and found it to be a worthy alternative to the Samsung 960 EVO. SanDisk's first consumer NVMe SSD has the same components, performance, and price, as the Black, but it targets a different type of user.

SanDisk products have always been marketed specifically to photographers, videographers, and other so-called "creative" types. The category has grown over the years, but companies can't restrict excellent products to specific applications. The SanDisk Extreme, Extreme II, and Extreme Pro are all good examples of breakout products that bled over to the enthusiast market.

The Extreme Pro SATA SSD was more than just an excellent product, though; it was the best for years. It was also the last Extreme Pro branded SSD to come to market. Even though the new WD and SanDisk SSDs use the same components, we had several reasons for not combining them into the same review. The Black branding has its own storied history that dates back to the days of spinning disks, but the Extreme Pro was a giant among flash. The Extreme Pro was the first consumer SSD with a ten-year warranty period, so early adopters still have up to six years of warranty coverage left.

The Extreme Pro raised the warranty bar, and Samsung was forced to match it with the 850 Pro. In most capacities, the Extreme Pro delivered better performance. For years, the two companies battled it out with performance-improving firmware updates.

Today we'll see if the new SanDisk Extreme Pro M.2 NVMe 3D SSD is a gem like its predecessor, or if it's just another rock in a growing pile of NVMe SSDs.

SanDisk will bring its first retail consumer NVMe SSD to market in 1TB and 500GB capacities. The Extreme Pro delivers up to 3,400/2,800 MB/s of sequential read/write throughput. The 1TB model also boasts up to 500,000/400,000 random read/write IOPS, but these performance specifications vary by capacity. Most users will not notice these differences during normal use.


We covered the full feature set in the WD Black 3D NVMe SSD review, so we won't go through the slide deck here. The important takeaways come from the controller that SanDisk has worked on for the last three years. It's a three-core controller designed by SanDisk using the latest NVMe 1.3 protocol and the company's new aggressive nCache 3.0 SLC buffer system, which boosts performance.

Pricing, Warranty, & Endurance

SanDisk covers the new Extreme Pro NVMe series with a five-year warranty that covers up to 300TB of data writes for the 500GB model and 600TB for the 1TB drive. Pricing at retail appears to be holding steady at $229.99 and $449.99, respectively.


The new Extreme Pro comes to market with a better-looking retail package than the WD Black, but it conveys the same information on the box.

A Closer Look

We thought the Extreme Pro's metal sticker would make it faster than the new Black, which comes with a plastic sticker, but it turned out to be nothing at all. In our testing, neither SSD entered a thermal throttling condition during typical workloads, so the sticker doesn't appear to have an impact.
