Condition: New
Note: price and availability are subject to change without prior notice
WD BLACK SN850X 2TB NVMe SSD is now available at Mascom International for KSh 36,500, ready to drop into any PCIe Gen4 M.2 2280 slot. This WD BLACK SN850X reaches sequential read speeds of 7,300 MB/s and write speeds of 6,600 MB/s, with random performance up to 1,200,000 read IOPS and 1,100,000 write IOPS. The drive uses SanDisk 112-layer 3D TLC NAND and a DRAM cache. Find the WD BLACK SN850X at Mascom International, Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, with pay-on-arrival delivery to all 47 counties.
Built for PC gamers, video editors, and software developers across Kenya, the WD BLACK SN850X solves the slow load times and storage bottlenecks that hold back older SATA drives and entry-level NVMe sticks. Content creators in Nairobi exporting 4K timelines wait less for renders to write. Software developers at iHub-affiliated startups compile large codebases faster off the 2TB capacity. PS5 owners gain room for 30 to 40 modern game installs. The WD BLACK SN850X handles the heavy read and write cycles that daily creative and gaming work demands.
At Mascom International, we're seeing gamers and creators move from 512GB SATA setups to the WD BLACK SN850X for the jump in throughput and capacity. Users consistently report shorter level-load times and quicker project saves after the swap. Unlike other electronics retailers in Kenya, Mascom International lets you confirm the drive and price in person at our Nairobi CBD store before you pay. Order the WD BLACK SN850X today and pay only when it reaches your door.
Common Questions About the WD BLACK SN850X 2TB NVMe SSD
How fast is the WD BLACK SN850X in real use?
The WD BLACK SN850X hits up to 7,300 MB/s sequential reads and 6,600 MB/s sequential writes on a PCIe Gen4 x4 link. In practice, that means a 50GB game install copies in well under a minute on a matching board. Random performance reaches 1,200,000 read IOPS and 1,100,000 write IOPS, which speeds up app launches and project loading. These figures place it among the quicker mainstream Gen4 drives sold in Kenya.
Will the WD BLACK SN850X work in my PlayStation 5?
Yes, the WD BLACK SN850X meets Sony's PS5 expansion drive requirements for capacity and speed. The bare M.2 2280 version needs a separate compatible heatsink before fitting it into the PS5 storage slot. A factory heatsink variant of the SN850X is also sold for buyers who prefer a ready-to-install option. Mascom International staff can confirm which version suits your PS5 and supply a matching heatsink if you need one.
What system do I need to run the WD BLACK SN850X at full speed?
The WD BLACK SN850X needs a motherboard with a PCIe Gen4 M.2 2280 slot to reach its rated 7,300 MB/s read speed. It still works in older PCIe Gen3 boards but caps near 3,500 MB/s on that link. Most AMD Ryzen 3000-series-and-newer and Intel 11th-Gen-and-newer systems support Gen4. The drive is single-sided, so it fits thin laptops and compact builds with limited M.2 clearance.
Is the WD BLACK SN850X 2TB worth KSh 36,500 in Kenya's market?
For gamers and creators who write large files daily, the WD BLACK SN850X 2TB earns its KSh 36,500 price through speed and a 1,200 TBW endurance rating. That endurance covers roughly 657GB of writes every day for five years. The 2TB capacity holds 30 to 40 large games or terabytes of 4K footage. Buyers throughout Kenya tell us the load-time gains alone justify the upgrade over cheaper drives.
How does the WD BLACK SN850X compare to the Samsung 990 Pro?
The WD BLACK SN850X and Samsung 990 Pro post near-identical rated speeds, both reaching around 7,300 MB/s reads on PCIe Gen4. Both use DRAM-backed controllers and TLC NAND, and game-load tests separate them by fractions of a second. The SN850X often lands at a friendlier Kenyan price for the same 2TB capacity. For most builders, the choice comes down to price and stock, which Mascom International confirms on request.
What is Game Mode 2.0 on the WD BLACK SN850X?
Game Mode 2.0 is a software feature in the SanDisk Dashboard app that tunes the WD BLACK SN850X for Windows gaming. It uses predictive loading to prepare game data before you need it, trimming stutters during fast scene changes. The dashboard also reports drive health, temperature, and remaining endurance. The feature runs on Windows PCs only and does not affect PS5 use, where the drive runs at native NVMe speed.
How does the WD BLACK SN850X handle heat during long sessions?
The WD BLACK SN850X uses Adaptive Thermal Management to hold steady speeds during extended gaming and editing sessions. The controller eases performance gradually as temperatures climb instead of dropping sharply, which keeps frame loading consistent. For heavy sustained workloads, pairing the bare drive with an M.2 heatsink keeps temperatures lower. Gamers in Kenya's warmer Mombasa and Kisumu climates benefit from this thermal headroom during marathon sessions.
What capacity options exist beyond the 2TB WD BLACK SN850X?
The WD BLACK SN850X family runs from 1TB up to 8TB, but the 2TB model is the value sweet spot. It matches the larger drives on the full 7,300 MB/s read ceiling and 1,200,000 random read IOPS, which the 1TB version does not reach. The 2TB capacity suits most gaming libraries and editing projects without paying the higher 4TB cost. Mascom International stocks the 2TB SN850X and can source other capacities on request.
Technical Specifications
