Looking at current storage prices, I still can’t believe the insane value I got for this level of speed and capacity!Key Highlights:Reliability: After running continuous workloads in a 24/7 home server environment for months, this drive has been rock-solid with zero errors, thermal issues, or stability hiccups.Incredible Speed: With read/write speeds up to 7400/6500 MB/s, it handles high-bandwidth data transfers effortlessly.NAS & UnRAID Integration (Ease of Use): It was pure plug-and-play. I use this drive as a high-speed cache pool in UnRAID, and it chews through heavy write operations, docker containers, and temporary file transfers without breaking a sweat.Boot Speed / Responsiveness: While I use it specifically as a cache drive rather than an OS boot disk, given its lightning-fast read access speeds, I have no doubt it would make a system boot almost instantaneously.Software: Since it's deployed inside an UnRAID environment, I don't use the native Windows management software/dashboard, but raw system reporting and SMART monitoring work flawlessly.Power Consumption & Temps: Extremely efficient. Even under sustained loads, the integrated heatsink keeps temperatures well within optimal limits without drawing excessive power.Final Verdict:Whether you're building a high-performance PC, upgrading a PS5, or running a demanding NAS cache pool like me, this drive delivers flagship PCIe Gen4 speeds and exceptional reliability. Easily one of the best hardware purchases I've ever made! ### ⭐⭐⭐⭐⭐ Becoming More Of A Fan Every Device *by on Reviewed in the United States September 8, 2025* I've slowly been using Lexar more and more through the years. I haven't used them as my main brand for important things, but I have been trying them out for secondary devices or backups to see how well they function. Over the past five years, nothing has broken on me, which is why I decided to get this drive to put inside my desktop for my PC games.This is a Gen4 NVMe drive. I won't reiterate all the specs, but it is a DRAM-less drive, and substitutes HMB (host memory buffer) as the cache instead of being on the drive. This makes it a little slower, but you get the benefit of a lower operational temperature. For me, games already load and run fast, and having it be cooler was better for me, personally, as an IT guy. I prefer things to last longer than be faster and burn out.So far, this drive blazes. The heatsink looks nice, even though I won't ever see it in my desktop, and anything to help reduce heat is always a plus. However, if you get an NVMe with a heatsink, if you decide you want to turn it into an external drive, you have limited options when putting it in a portable external drive, at least currently. I had debated getting a plain drive without a heatsink, but it was actually cheaper to get it with the heatsink at the time of purchase.Overall, this NVMe was quick to install, easy to partition, and has been as quick as the Samsung 990s to use. Recommended. ### ⭐⭐⭐⭐⭐ Fast, reliable, easy to install, great for the PlayStation 5! *by on Reviewed in the United States June 18, 2024* This is one of the best M.2 SSDs I own. As a first time M.2 NVMe SSD owner I'm glad I made the switch to these types of SSDs as I also own a 4 TB Samsung 990 Pro with Heatsink for my gaming PC. The Lexar NM790 not only gives my PS5 great performance loading times are 10x fast. I only have to wait 11 seconds from the title screen into the game for Assassin's Creed Valhalla. in the Console storage I had to wait about 50 seconds sometimes even 60 seconds. It's easy to install as well.Remove the bottom plate. Take the SSD medal cover off remove the screw in the standoff space. Install the SSD and screw the screw at the end of the SSD. Put the medal cover back on the SSD housing. Put the bottom plate back on the PS5 and you're done! It takes less than a minute to install! This bad boy can hold about 50 games on your PS5. Buy it, you won't regret it! ## Frequently Bought Together - Lexar 4TB NM790 SSD with Heatsink PCIe Gen4 NVMe M.2 2280 Internal Solid State Drive, Up to 7400/6500 MB/s Read/Write, Compatible with PS5, for Gamers and Creators, Black (LNM790X004T-RN9NU) - G.SKILL Trident Z5 Neo RGB Series (AMD Expo) DDR5 RAM 64GB (2x32GB) 6000MT/s CL30-40-40-96 1.40V Desktop Computer Memory UDIMM - Matte Black (F5-6000J3040G32GX2-TZ5NR) - Thermaltake SWAFAN EX 12 ARGB PC Cooling Fan, 3-Fan pcak, 500~2000 RPM, Magnetic Connection, Reversable Blades, sync with MB RGB Software, CL-F167-PL12SW-A, 120mm, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/573616885-lexar-4tb-nm790-nvme-ssd-w-heatsink-7400-6500-mb](https://www.desertcart.tn/products/573616885-lexar-4tb-nm790-nvme-ssd-w-heatsink-7400-6500-mb) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-27*
