Mascom International stocks the SanDisk Optimus 5100 1TB at KSh 24,000, brand new and sealed, with sequential reads up to 7,100MB/s and writes up to 6,700MB/s. This M.2 2280 NVMe drive runs over a PCIe Gen4x4 link, carries part number SDSP51100TAN, and is rated for 600TB of total writes. SanDisk includes a five-year limited warranty and a five-year Acronis True Image licence for backups. The SanDisk Optimus 5100 is on the shelf at our store in the Old Mutual Building on Kimathi Street, Nairobi CBD, and we deliver countrywide with payment on arrival.
Built for PC gamers, content creators, developers and busy professionals across Kenya, the SanDisk Optimus 5100 deals with two problems at once: slow loading and a drive that keeps filling up. A YouTuber in Kilimani editing weekly videos, a developer in Westlands compiling large projects and a PS5 owner short of space all gain here. Programs open quicker, game levels load faster and big exports finish sooner. With 1TB on board, the SanDisk Optimus 5100 holds a working operating system, your main apps and several large games with room to spare.
Where most Nairobi electronics shops push unbranded NVMe sticks with vague speed claims, Mascom International sells the SanDisk Optimus 5100 sealed, with its part number printed on the label. Buyers throughout Kenya report that the included Acronis backup licence matters as much as the speed, since it protects work from failed laptops and theft. The SanDisk Optimus 5100 also costs KSh 5,000 less than the Lexar NM790 1TB on our shelves, with a read speed only slightly lower in daily use.

Common Questions About the SanDisk Optimus 5100
How much does the SanDisk Optimus 5100 1TB cost in Kenya?
The SanDisk Optimus 5100 1TB costs KSh 24,000 at Mascom International in Nairobi CBD, brand new in its sealed pack. That covers the drive, our 6-month warranty on manufacturing defects, and pay-on-arrival delivery to all 47 counties. SanDisk adds its own five-year limited warranty and an Acronis True Image licence. The WD Blue SN5100 500GB costs KSh 13,500, so the 1TB adds KSh 10,500 for twice the space. Confirm current stock on WhatsApp before you travel into town.
How is the SanDisk Optimus 5100 different from the WD Blue SN5100?
The SanDisk Optimus 5100 and the WD Blue SN5100 are both SanDisk Gen4 drives built on SanDisk QLC 3D CBA NAND flash. In our store the two differ by capacity and speed. The SanDisk Optimus 5100 1TB reads up to 7,100MB/s, while the WD Blue SN5100 500GB reads up to 6,600MB/s. Choose the SanDisk Optimus 5100 if you game, edit or store large projects. Choose the 500GB WD Blue SN5100 for a simple office boot drive.
Should I get the SanDisk Optimus 5100 1TB or the Lexar NM790 1TB?
The SanDisk Optimus 5100 1TB costs KSh 5,000 less than the Lexar NM790 1TB at Mascom International. The Lexar NM790 reads up to 7,400MB/s against 7,100MB/s on the SanDisk Optimus 5100, a gap few people notice in daily use. The SanDisk Optimus 5100 adds a five-year Acronis True Image backup licence. Pick the SanDisk Optimus 5100 for value and built-in backup software. Pick the Lexar NM790 if you want the faster read figure and are happy to pay for it.
Is the SanDisk Optimus 5100 a good PS5 upgrade?
The SanDisk Optimus 5100 suits the PlayStation 5 expansion slot, with the M.2 2280 size, a PCIe Gen4x4 link and read speed above Sony's recommended level. Sony advises fitting a heatsink on any drive inside the console, and this one arrives without one, so add a slim heatsink to your order. At 1TB, it roughly doubles the usable game space of many PS5 models. Gamers in Nairobi tell us that ends the habit of deleting a game every time a new release lands.
Can the SanDisk Optimus 5100 handle Kenyan heat, dust and power cuts?
The SanDisk Optimus 5100 is rated to run from 0°C to 85°C, so a warm office in Mombasa or a stuffy cyber café sits well within its limits. Dust is a case issue rather than a drive issue: clean desktop vents regularly in Industrial Area workshops. KPLC power cuts are the bigger risk, since sudden loss of power can damage a file being saved. Use a UPS on desktops, and let Acronis True Image make scheduled backups of your KRA, eCitizen and M-Pesa records.
Who should buy the SanDisk Optimus 5100, and who should skip it?
Buy the SanDisk Optimus 5100 if you game on a PC or PS5, edit video or photos, or want one fast drive for both Windows and your working files. It suits buyers who value bundled backup software. Skip it if you need several terabytes for raw footage archives; the Lexar NQ780 2TB at KSh 47,500 serves that better. Skip it too if your laptop only takes 2.5-inch SATA drives, where the HIKSEMI Wave S 1TB at KSh 17,000 fits instead.
What does the Acronis licence with the SanDisk Optimus 5100 do?
The SanDisk Optimus 5100 comes with Acronis True Image for SanDisk, a five-year licence that must be redeemed within 90 days of purchase. Acronis can clone your old drive onto the new one, so Windows and your programs move across without a fresh install. It can also run scheduled backups to an external drive. For accountants, lawyers and small business owners, that means client files survive a stolen laptop or a dead motherboard. SanDisk Dashboard, also free for Windows, tracks drive health and firmware updates.
How long will the SanDisk Optimus 5100 1TB last?
SanDisk rates the SanDisk Optimus 5100 1TB for 600TB written and 1.75 million hours MTTF, mean time to failure. If you wrote 50GB every day, a heavy load for a home or office user, you would take about 32 years to reach that endurance rating. Most people write far less, so the drive should outlast the laptop or desktop it sits in. The five-year SanDisk warranty reflects that expected lifespan, and SanDisk Dashboard lets you watch remaining life as the years pass.
Technical Specifications
Performance and Speed
- Sequential read up to 7,100MB/s — games, video projects and large programs load in a few seconds instead of minutes.
- Sequential write up to 6,700MB/s — exports, downloads and big file copies finish quickly instead of stalling your work.
- Random reads up to 1,000,000 IOPS — input/output operations per second, the measure behind fast app launches and multitasking.
- Random writes up to 1,300,000 IOPS — thousands of small saves at once, as in code builds and databases, stay quick.
- PCIe Gen4x4 NVMe link — four Gen4 lanes, roughly 13 times faster than the 550MB/s limit of SATA drives.
Capacity and Real-World Storage
- 1TB raw capacity, about 930GB usable in Windows — space for the system, your apps and a large set of files.
- Holds roughly 310,000 photos from a 12MP camera, covering years of personal and work photography in one place.
- About 44 hours of 4K video at 30fps, or roughly 119 hours of 1080p footage for vloggers and event shooters.
- Room for Windows, Office, creative software and several large modern games together without constant uninstalling.
- Big enough to serve as a single drive for most students, office staff and home users for years.
Interface and Compatibility
- M.2 2280 form factor — 22mm wide and 80mm long, the standard M.2 slot size in current laptops and desktops.
- Works in PCIe Gen3 M.2 slots as well, with speed limited to what the older slot can carry.
- Suits the PlayStation 5 expansion slot; Sony advises a heatsink, which you buy separately.
- Fits business laptops such as HP EliteBook and Lenovo ThinkPad models with an NVMe M.2 slot.
- Requires an NVMe-capable M.2 slot and will not work in a 2.5-inch SATA bay or a SATA-only M.2 slot.
Build, Endurance and Reliability
- 600TB written endurance rating — writing 50GB every day would take about 32 years to use it up.
- 1.75 million hours MTTF — mean time to failure, a lab measure of how rarely drives of this model fail.
- Operating range of 0°C to 85°C, wide enough for hot offices, closed cabinets and gaming rooms.
- SanDisk 8th-generation BiCS QLC 3D CBA NAND — dense flash memory that keeps the cost per gigabyte low.
- Measures 80 x 22 x 2.38mm and weighs 5.7 grams, so it slips into thin laptops without trouble.
Software and Backup
- Acronis True Image for SanDisk — a five-year licence for cloning and backups, redeemable within 90 days of purchase.
- Drive cloning through Acronis moves Windows, programs and files from your old drive with no reinstall needed.
- Scheduled backups to an external drive protect client files from theft, damage or a failed laptop.
- SanDisk Dashboard for Windows — reports remaining drive life and temperature, and checks for firmware updates.
- Five-year limited SanDisk warranty, backing the drive well beyond the usual upgrade cycle of most computers.
Package Contents
The SanDisk Optimus 5100 arrives in SanDisk's sealed retail pack containing the 1TB drive itself, with the Acronis True Image licence redeemed online through SanDisk. No screw, heatsink, cable or enclosure is listed in the box, so keep the M.2 screw from your current drive. PS5 owners should pick up a heatsink separately. If you plan to clone a single-slot laptop, ask our team on WhatsApp about an external M.2 enclosure.
Warranty
Mascom International backs the SanDisk Optimus 5100 with a 6-month warranty covering manufacturing defects under normal use. Claims are handled at our Nairobi CBD service desk on Kimathi Street. SanDisk's own five-year limited warranty also applies to the drive.
