1TB NM790 Internal NVMe SSD, 7400/6500 MB/s, M.2 2280, PCIe Gen 4x4

I've been looking at getting a larger NVMe SSD for a year or so now but prices have largely remained steady up until Fall off this year when they really started to get more affordable. This is replacing an older Gen 3 MP510 960GB. I was getting rather tired of having to pick and choose what I wanted installed on the drive. I picked the Lexar after reading numerous reviews and seeing nothing but positives. It's TLC based drive unlike most of the others around this price point for 4TB models. QLC drives have their own issues, the most concerning being longevity, as their NAND is much more easily worn out and typically do have any DRAM so in heavy or intense workloads they can drop to speeds like that of normal mechanical hard drive. It's got a rather high endurance rating, over twice the 1400 TBW of the drive out replaced. This was another reason for getting this as I don't have to worry about the drive failing due to exhausting the endurance. I'm sure I'll be looking gone before the drive would fail. One incredible thing is that Lexar managed to get all 4TB on a single side of the NVMe. Most drives they're on both sides making it harder to cool. My only con is that it does run quite warm. It does sit under my GPU and in general, idling on the desktop it can sit in the 50's. If your motherboard doesn't have a heatsink, you'll want to pick one up. I can't imagine how much worse it could be if I didn't have 2 140mm intakes on the side above the GPU blowing air down onto the board. I did buy a heatsink but have not yet installed it so I'll likely be looking at around a drop off 10-15C or more. If the extra $15-20 for the heatsink model didn't bother you, go that route. I will say I am hampering the drive as the m.2 slot it occupied is only a PCIE Gen 3 so it won't ever hit it's true speeds, but when I tested it, it was hitting the limit of the maximum bandwidth. I was getting identical read and write speeds capping out around 3500MB/s, a little less than half what the drive is capable of. If you're looking for speed, endurance, size options and a good price, the Lexar is the way to go. They've been in the storage game for a long time and have always been reliable for flash based storage

Edited 4/27/2024- Increased overall rating to 5 stars. After 6+ months, this ssd is still working perfect and hasn't really lost any speed or health (see 2nd pic) even though it has had over 3TB of data on it for the last 4 months. Great drive and glad I purchased 2 before the prices increased. I still think it's worth it at the current price. I've been running 2x 2tb Samsung 980 Pro ssd's on my Lenovo Legion Pro 5 16IRX8 and was getting low on D: drive space. I could have shared some C drive space but with ssd prices being what they are at the present time, why bother? I decided it was time to step up to a 4TB ssd but I chose to try saving a little money and went with the Lexar NM790 4TB. I've used many Lexar storage products in digital cameras and digital audio players in the past and have never had one fail. It is my understanding that Lexar has changed hands so the jury is out as to whether this ssd will live a long reliable life, much like all of the previous Lexar products that I've owned. Having said this, so far I'm very happy with the drive, especially for my needs and the money spent. I am using it strictly as a game storage drive so my opinion may or may not be different if I were using it as an OS/boot drive. The Samsung 2tb 980P will continue to be my OS/boot drive since I know it's reliable, has DRAM and there's still plenty of room left for my DAWs and music. I did go ahead and run the CrystalDiskMark test set to the NVME settings. I only ran a single test in order to see what the drive was capable of when filled to 56% with over 2TB of data. In actual use, it works as good as the 980P and I have no complaints. Color me surprised- this drive is actually showing as good if not better numbers than the 35% full Samsung 980P 2TB. If this drive actually lives past the warranty, I will consider it an extremely good value. This is a much better deal than similarly priced QLC drives since this has TLC and is MUCH faster. Finally, someone produced a fast and affordable 4TB ssd without QLC.

Purchased this for my gaming computer on 10-18-2025 I paid 224 for it. It’s crazy how much everything has gone up. I wanted to wait a bit before I left a review but so far so good. No issues and has good transfer rate. I have no issues whatsoever I currently have 8TB in my pc and wanted to upgrade my other ones as well but by these prices I’ll wait till it comes back down.

Always, I can depend on the lexar good quality, and good price

These SSD’s seem to work in portable SSD enclosures. They are cheaper than my favorite Samsung 990 and really work nearly as well. Still fast (the Samsungs are a bit faster but unless you are transferring huge video files, it may not be a benefit) and the important thing is, these Lexars seem manageable heat well. But that is relative to the application too. Recommended

The value for money is tremendous with this SSD - fast, cheap, and huge (I have the 4TB version). The only weak areas are random writes and it runs hot if installed under a MB vendor heatsink under a huge video card. Without sufficient airflow, this will heat up to its max operating temp (and beyond) of 70c. I had to add another fan to my case to get this SSD to operate in the 58-64c range under heavy gaming. Only artificial disk benchmarking apps that stress the SSD to the max will take it to 70c now (for my configuration). At idle the SSD temps now runs in the low 50's. If your SSD slot is not encumbered by cards hanging over it and you can put a proper SSD heatsink on it with good airflow around it, you shouldn't have any trouble keeping it under 60c under stress. Even with the high heat this SSD is worth it! I highly recommend it!!

I bought this drive to place in my Thunderbolt 5 dock and use as storage for all the samples I use in music production. Installation was easy and my Mac recognized the drive and formatted it to APFS with no problems. Blackmagic speed test results for Thunderbolt 4 connection are 2183.6 MB/s write and 3110.8 MB/s read. As long as you're not editing H.265 12K video in real-time, this drive is fast enough to use as an external work drive on an M4 Mac Mini for video editing.

Works as promised!

Schneller guter Speicher. Habe schon den zweiten Speicher für Laptop und PC.

Good product. Faster speeds. Excellent quality. Already buy 2 time with seller. Thanks you seller

Los tiempos de espera con este SSD es son impresionantes. Perfecto y nunca se calienta, no he tenido problemas. Le coloque el shiled que funciona como disipador que viene con mi MOBO.

شغلته علي ps5 سريع جدااا
