The Lexar NM620 512GB is in stock at Mascom International, priced at KSh 14,000, brand new and sealed. This M.2 2280 solid-state drive uses the PCIe Gen3x4 NVMe interface and reads data at up to 3500MB/s, with writes at up to 2400MB/s on this capacity. The Lexar NM620 is built on 3D TLC NAND flash and rated for 250TB written over its life. You can collect one from our shop at Old Mutual Building, First Floor Room 4, Kimathi Street, in Nairobi CBD, or order it for pay-on-arrival delivery anywhere in Kenya.
Designed for students, office workers and small business owners, the Lexar NM620 replaces a slow hard drive or tired SATA SSD in any laptop or desktop with an M.2 NVMe slot. Windows starts in seconds, spreadsheets open without a pause, and large files copy in moments instead of minutes. A university student at JKUAT or Strathmore running coding tools and research PDFs gets a laptop that keeps up. An accountant pulling M-Pesa statements and KRA returns from eCitizen stops waiting on a spinning disk. For most people, the Lexar NM620 is the one part that changes how an older machine feels day to day.
Unlike other electronics retailers in Kenya that sell unbranded drives with no published speeds, Mascom International stocks genuine Lexar storage with clear specifications. At 512GB, the Lexar NM620 sits KSh 8,500 below the 1TB version of the same drive, which suits buyers who keep most files in the cloud or on an external disk. Customers across Nairobi tell us this upgrade is the cheapest way to stretch a laptop's working life. Visit the Kimathi Street store with your machine, or WhatsApp us its model before ordering so we can confirm the fit.
Common Questions About the Lexar NM620
How much is the Lexar NM620 512GB in Kenya?
The Lexar NM620 512GB costs KSh 14,000 at Mascom International on Kimathi Street, Nairobi CBD, in sealed Lexar retail packaging. The price includes our 6-month warranty and pay-on-arrival delivery to all 47 counties, so you pay only when the drive reaches you. The 1TB version of the Lexar NM620 costs KSh 22,500, a KSh 8,500 step up that doubles the space. That works out to about KSh 27 per gigabyte here, against about KSh 22.50 on the larger drive.
Will the Lexar NM620 fit my laptop or desktop?
The Lexar NM620 fits any laptop or desktop with an M.2 2280 slot that supports PCIe NVMe drives. The number 2280 means the card is 22mm wide and 80mm long, the most common size in laptops from recent years. Some older machines have M.2 slots that accept SATA drives only, and this drive will not work in those. Send your laptop or motherboard model to Mascom International on WhatsApp and our team will confirm the slot type before you pay.
Should I buy the Lexar NM620 512GB or the HIKSEMI Wave 512GB?
The Lexar NM620 512GB reads at up to 3500MB/s for KSh 14,000, while the HIKSEMI Wave 512GB reads at up to 3000MB/s for KSh 11,000. Both are M.2 PCIe Gen3 NVMe drives and fit the same slots. For booting Windows and opening apps, the two feel close. The Lexar suits buyers who copy large files often and want its published 250TB endurance rating and the 5-year limited warranty from Lexar. Pick the HIKSEMI Wave when the budget is tight and the machine mainly runs office work.
Is the Lexar NM620 safe to use when KPLC power cuts hit?
A sudden KPLC outage will not physically damage the Lexar NM620, but a file being saved at that exact moment can be lost or corrupted. Laptops are covered by their own battery, so the risk sits mostly with desktops and shop POS computers. Pair a desktop with a UPS so Windows can shut down cleanly when the lights go. Keep copies of key documents, such as KRA returns and M-Pesa statements, on a second drive or in cloud storage as well.
How much faster is the Lexar NM620 than a SATA SSD or hard drive?
The Lexar NM620 reads at up to 3500MB/s, roughly six times the 550MB/s ceiling of a 2.5-inch SATA SSD. A laptop hard drive is slower still, and its spinning parts dislike the knocks of a daily matatu ride. You notice the gap most when copying large folders, loading big projects or installing software. For booting Windows and browsing, any SSD feels far quicker than a hard drive, while the NVMe advantage shows up in heavier work.
Is 512GB on the Lexar NM620 enough for a university student?
For most university students, the Lexar NM620 512GB holds Windows, Microsoft Office, coding tools and years of notes with room to spare. After formatting, Windows shows about 476GB of usable space, enough for about 150,000 photos or about 60 hours of 1080p video. Students at the University of Nairobi or Kenyatta University who edit video or install large PC games should consider the 1TB version, since space fills faster than expected once projects and downloads pile up.
Can I move my files and Windows from my old drive to the Lexar NM620?
Yes, you can copy your existing Windows setup and files to the Lexar NM620 with cloning software and a USB-to-M.2 adapter, or install Windows fresh and restore your files. A fresh install often runs cleaner on an older laptop. Machines with a single M.2 slot need the adapter route, since both drives cannot sit inside at once. Back up your documents first, to an external drive or over a Safaricom or Airtel hotspot to cloud storage, before starting any transfer.
Who should buy the Lexar NM620 512GB and who should skip it?
Buy the Lexar NM620 512GB if your computer has an M.2 NVMe slot and you want quicker boots and file transfers on a mid-range budget. Skip it if you want PS5 expansion storage, because Sony requires a Gen4 drive; the Lexar NM790 1TB fits that role. Owners of a Gen4 laptop may prefer the WD Blue SN5100 500GB at KSh 13,500, which reads at up to 6600MB/s. Machines that only take 2.5-inch drives need the HIKSEMI Wave S 512GB instead.
Technical Specifications
Performance and Speed
- Sequential read up to 3500MB/s — large files such as video projects and software installers open in a few seconds.
- Sequential write up to 2400MB/s on the 512GB capacity — copying a full folder of camera photos finishes quickly.
- Random read up to 200K IOPS — IOPS counts small operations per second, which decides how fast Windows and apps respond.
- Random write up to 256K IOPS — saving many small files at once, like code projects or email archives, stays quick.
- PCIe Gen3x4 link with the NVMe 1.4 protocol — four data lanes talk directly to the processor, skipping older SATA limits.
Capacity and Real-World Storage
- 512GB raw capacity — Windows shows about 476GB usable after formatting, which is normal for every storage drive.
- Room for about 150,000 photos at 3MB each — years of phone and camera pictures kept in one place.
- About 60 hours of 1080p video or about 22 hours of 4K footage recorded at standard settings.
- Holds Windows, Microsoft Office, browsers and accounting software with plenty of space left over for documents.
- About KSh 27 per gigabyte at KSh 14,000 — a sensible middle point for fast NVMe storage in this batch.
Interface and Compatibility
- M.2 2280 form factor, 22mm wide and 80mm long — the standard slot size in most modern laptops and motherboards.
- Needs an M.2 slot that supports PCIe NVMe — slots built for SATA M.2 drives only will not detect it.
- Works in PCIe Gen4 slots at Gen3 speeds — newer laptops and desktops accept it without any adapter.
- Slim 2.25mm thickness — slides into thin laptops where a bulkier drive or add-on cooler would block the cover.
- Not suited to a PS5 expansion slot — Sony's console asks for a PCIe Gen4 drive for that bay.
Build, Endurance and Reliability
- 3D TLC NAND flash — stacked memory cells that balance speed, capacity and lifespan for everyday computing.
- Rated for 250TB written — about 137GB of new data every day for five years before reaching that rating.
- 1,500,000-hour MTBF — mean time between failures, a reliability measure the maker calculates across large numbers of drives.
- Operating range of 0°C to 70°C — covers the internal temperatures of a normally ventilated laptop or desktop.
- Rated for 1500G shock and 20G vibration — no moving parts, so bag knocks carry far less risk than with hard drives.
Inclusions and Support
- The drive alone in sealed Lexar retail packaging — no screw, as most laptops keep their own M.2 screw.
- Five-year limited warranty from the maker — the manufacturer's own coverage term, alongside the Mascom International in-store warranty.
- Mascom International 6-month warranty — manufacturing defect claims are handled at our Nairobi CBD service desk.
- Slot check on WhatsApp before purchase — send your laptop model and our team confirms the drive will fit.
- Pay-on-arrival delivery — you inspect the sealed pack and pay only once it is in your hands.
Package Contents
The Lexar NM620 512GB comes as the drive alone, sealed in its Lexar retail pack. There is no mounting screw, heatsink or cloning cable in the box, because most laptops and motherboards keep their own M.2 screw beside the slot. If your machine is missing that screw, or you want an external enclosure to copy your old drive, ask our team on WhatsApp what suits your model. We check the seal with you at collection or on delivery.
Warranty
Mascom International backs the Lexar NM620 with a 6-month warranty covering manufacturing defects under normal use. Claims are handled at our Nairobi CBD service desk on Kimathi Street. Lexar's own 5-year limited warranty also applies to this drive.
