WD_Black SN7100 1TB NVMe SSD – Gen4 PCIe, M.2 2280, Up to 7,250 MB/s Read Speed, Up to 6,900 MB/s Write Speed, Next Gen TLC 3D NAND, for Laptops, Handheld Gaming Devices – WDS100T4X0E

WD_BLACK 4TB SN7100 – Best NVMe money can buy
I bought the WD_BLACK SN7100 4TB to replace my smaller WD SN570 Gen3 boot drive. Installation was straightforward i.e just slide it into the M.2 slot, and done.PerformanceUsing CrystalDiskMark V9.5.0, I consistently saw around 7000 MB/s read and 6200 MB/s write on the 4 GB test, and about 6800 MB/s write on the longer 64 GB run which was remarkably close to the advertised specs. Random 4K read/write speeds also feel quick, and Windows 11 boots in roughly 5–6 seconds. However, I did observe some throttling when running 64GB Q8T1 test with temperature reaching 59°C and speed dropping to 4500MB/S. Though, it’s still faster than any Gen3 drive. App launches are near-instant. I haven’t tested large game installs (like 100 GB titles) since this particular system isn’t built for heavy gaming, but for productivity and content creation, it’s been great so far.Thermals and EfficiencyIdle temperature hovers around 30°C but under sustained load, temperatures could reach up to 60°C and this is without a heatsink(except some black material came with the original laptop drive) which for a Gen4 drive is exceptional. The controller here isn’t just fast but impressively power-efficient. Compared to my older Samsung 970 EVO Plus Gen3, this one runs at a lower wattage. It’s a great fit for laptops or compact builds where cooling headroom is limited.Storage Capacity and SoftwareUsable space comes out to about 3.63 TB, which is standard for 4 TB drives due to the difference between base-10 and base-2 (1000 vs 1024) calculations. My only gripe is WD’s software. The legacy Dashboard app has been replaced by Kitfox, and the 4 TB SN7100 isn’t fully recognized yet. Hopefully, WD or SanDisk pushes an update soon, as the drive itself is fantastic. Also, it could be formatted for Windows, Linux or MacOS.Value and EnduranceThis drive uses TLC 3D NAND, unlike the WD SN5000 which is QLC-based(4TB version) and often priced just a few dollars cheaper. The SN7100 offers an endurance rating of up to 2400 TBW, which should easily outlast multiple system builds. If you plan to use it in a server or NAS, I’d suggest either keeping a backup drive(RAID 1) or going with WD Red SN700, which is designed for heavier write cycles. While it’s not the cheapest 4 TB Gen4 SSD, the performance easily rivals the Samsung 990 Pro and Crucial T500, with the added benefit of lower power consumption and cooler thermals.VerdictIf you’re upgrading from an HDD or even a SATA SSD, the SN7100 feels like a quantum jump. It combines blazing fast speed with stable thermals, and generous capacity in one package. This is an excellent choice for prosumers(creators, gamers) or anyone who’s looking for a reliable performance with minimal heat output.To conclude, if you’re looking for a drive that stays cool, handles large transfers without any hiccups, and just works; look no further. Highly recommended.

Very good NVMe.
Amazing SSD, bought it right after it released for a very good price. (RIP pc part prices)Upgraded from a terrible 500GB SSD to this, storage is easily one of the most important things to make a computer feel snappy and responsive, it has amazing performance and nearly 1 full year later the drive is at 99% health according to the WD Dashboard.

Great price, great product WD does not disappoint!!!!
This drive works absolutely perfectly! I am a big fan of WD, and this series fails not! the RW speeds are great, and I have response time that are not noticeable! The price is fair, and it is everything I expected! Thank you again WD!

Such a great SSD
Works great had just a hdd at first after using this as my windows installment space it made my computer process quicker and respond better 1tb is well enough space for me to use with an ssd but some people may need more of u use a lot of space installig it was easy just find your ssd screw and install it

J’ai déjà eu un WD black sn770, toujours fiable et rapide, celui là me paraît encore mieux! Je fais confiance à cette marque de disques éprouvée et sa solide réputation! Pour le boulot c’est un bon investissement

amazing storage that is definitely worth every ounce of its price! With astronomically high storage of 2 terabytes you can fit in all of your favourite games and other applications needed without worrying about running of of storage. Very easy to setup and put into the motherboard and has very quick speeds for it to read and write data and so this makes it quick to launch games or any other apps that you may need to use in a short notice. Due to its high speeds, games run technically fast than other types of storage devices leading to much higher fps. It is also high quality so I expect it to last me for many years to come. Finally, it doesn’t get hot at all meaning that it will not fail me when running my pc.

Empaque muy bonito, funcional, protegue bien al SSD, 400GB se “pierden” por tablas del ssd, las velocidades estan cerca de las descritas por el fabricante, cabe señalar que depende mucho de la tarjeta madre y el puerto. Adjunto las pruebas de lectura escritura en el PCIE4.
