The best SSD on the block is Lexar NM790. We can't think of a greater success story in the storage industry than Lexar. This used to be a professional/creator focused brand under Micron Technology, mostly dealing in memory cards and flash drives, but has since been acquired by Longsys, which put it to great use for the entire catalog of client memory products, including memory modules, and SSDs, besides the removable flash storage products. The NM790 is a solidly put together drive that breaks the mold of controller+NAND flash combinations from the usual brands, and instead goes with Maxiotech's fastest Gen 4 NVMe controller, the MAP1602A; paired with 232-layer 3D TLC NAND flash by YMTC, the company that has the incumbents spooked to the extent of erecting trade barriers against it. The 232-layer flash chip uses the company's second generation Xtracking 3D flash stacking and interconnect technology. The fingernail-sized Maxiotech controller is DRAMless, which makes this feat even more impressive.
The NM790 in its 4 TB variant that we tested with its PS5-friendly heatsink, crushed every test in our bench. We at TechPowerUp guide our readers to real-world storage benchmarks, and test in various sequential and random access tests of various queue depths. We also focus on sustained write performance, so we know that a drive's performance doesn't fall off a cliff after a small amount of continuous writes in a large file-transfer operation. The NM790 has great performance overall, despite a little spot here and there with synthetic random access tests. It's able to sustain its expected write performance over a vast 600 GB region, beyond which it drops to around 1.8 GB/s for the following 2 TB, and only begins to crawl beyond 2.5 TB, which goes to show that the drive is able to intelligently treat a large amount of its TLC NAND media as MLC (2 bits per cell), and even 275 GB of it as SLC.
As a tiny 12 nm DRAMless chip, the Maxiotech controller is a lot better behaved in terms of thermal throttling than competing solutions. As you'll see in our older reviews of the 2 TB and 4 TB variants of the NM790 without the heatsink, the added cooling is simply nice-to-have for PS5 compatibility, but isn't something you need. The real ace up Lexar's sleeve is pricing, and with $110 for the 2 TB variant, $210 for the 4 TB, and $50 extra for the heatsink (which you really don't need), these drives are very well priced.
