Samsung has been caught swapping the components in their 970 EVO Plus SSD. The new 3D TLC NAND chips are not performing as well as expected, and users have seen a significant performance hit when the cache is filled.

Choosing a fast SSD has become a particularly difficult procedure that requires considerable study beyond the specs given on the box.

Samsung is the latest storage company to be discovered changing components in certain SSDs without properly informing consumers, following in the footsteps of Crucial and Western Digital. The drive in issue is the 970 EVO Plus, a popular NVMe M.2 drive with read/write speeds of up to 3,500/3,300 MB/s.

The Phoenix controller (S4LR020) in the original 970 EVO Plus has been changed with the Elpis controller, as found by a Chinese YouTuber (S4LV003). This is the same controller that Samsung employs in their 980 PRO SSD, a higher-end device that supports PCIe 4.0 for read/write speeds of up to 7,000/5,000MB/s.

Despite what seems to be a good change on the surface, benchmarks have shown that when Samsung’s redesigned 970 EVO Plus SSD’s SLC cache is depleted, write performance drops like a rock. This is a problem that content producers working with 4K movies and other big files are likely to face.

Samsung has yet to issue a statement confirming the modifications to its 970 EVO PLUS SSD, but storage aficionados may recognize the updated model by looking for a package with a vertical design. A new firmware is also included with the updated version (3B2QEXM7).

[…] The previous version began at 1,750 MBps and gradually decreased to 1,500 MBps after 40GB. The drive maintained a steady speed of 2,500 MBps on the new version, but after the 115GB SLC cache was depleted, the SSD dropped to 800 MBps. This resulted in a 47 percent drop in performance.
