UGREEN CM400 M.2 NGFF SSD Enclosure is in stock at Mascom International, priced at KSh 2,500, brand new and sealed, for M.2 SATA drives in the B-key and B+M key formats. It links to a computer at up to 5Gbps through a USB-C port and accepts drive lengths of 2230, 2242, 2260 and 2280. The UGREEN CM400 M.2 NGFF SSD Enclosure is built around the ASM225 controller inside an aluminium alloy body. Visit us at the Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, or order it to your door.
Built for laptop upgraders, field engineers, photographers and NGO field staff across Kenya, the UGREEN CM400 M.2 NGFF SSD Enclosure rescues a small part that is easy to forget. Many ultrabooks from the last decade shipped with an M.2 SATA stick, often 128GB or 256GB, which gets swapped out when the owner moves to a bigger NVMe drive. Fitted into this metal case, that old stick becomes a fast USB drive the size of a pack of chewing gum. Field teams travelling between Nairobi, Garissa and Kitale can carry survey data and site photos without trusting a cheap flash disk.
Where most Nairobi electronics shops push generic M.2 cases without telling buyers which drive types work, Mascom International explains the B-key difference before you pay. Buyers throughout Kenya report the same mistake: buying a case that turns out to be NVMe-only for a SATA stick, or the other way round. Our team checks the notch on your drive at the counter and confirms the UGREEN CM400 M.2 NGFF SSD Enclosure suits it. Order on WhatsApp if you cannot come in, and pay through M-Pesa or cash on delivery. The UGREEN CM400 M.2 NGFF SSD Enclosure then reaches you anywhere in the country.
Common Questions About the UGREEN CM400 M.2 NGFF SSD Enclosure
How much does the UGREEN CM400 M.2 NGFF SSD Enclosure cost in Kenya?
Mascom International in Nairobi CBD sells the UGREEN CM400 M.2 NGFF SSD Enclosure at KSh 2,500, brand new and sealed. The box holds the aluminium enclosure, a 50cm USB-A to USB-C cable and two rubber fasteners for securing the drive. A 6-month warranty from Mascom International comes with it, and pay-on-arrival delivery reaches all 47 counties. It costs KSh 800 more than the UGREEN US221 2.5-Inch SATA Hard Drive Enclosure, which is the right buy only for larger 2.5-inch laptop drives.
Will my SSD work in the UGREEN CM400 M.2 NGFF SSD Enclosure?
The UGREEN CM400 M.2 NGFF SSD Enclosure works only with M.2 SATA drives keyed B or B+M, the sticks often labelled NGFF. Check the gold edge of your drive: a SATA stick usually shows two notches, while most NVMe drives show a single notch near one side. NVMe, PCIe AHCI and mSATA drives will not run in this case. Drives may be 2230, 2242, 2260 or 2280 in length, the last two digits giving the length in millimetres. Capacity is supported up to 2TB.
How does the UGREEN CM400 M.2 NGFF SSD Enclosure compare with the UGREEN US221 2.5-Inch SATA Hard Drive Enclosure?
The two cases serve different drive shapes, so the drive you own decides between them. The UGREEN CM400 M.2 NGFF SSD Enclosure takes slim M.2 SATA sticks in a metal body about the size of a highlighter pen. The UGREEN US221 2.5-Inch SATA Hard Drive Enclosure takes the thicker 2.5-inch laptop drives, in plastic, up to 6TB. Both connect at 5Gbps over USB-C. If you have a stick, choose the CM400; if you have a rectangular laptop disk, choose the US221.
Does the UGREEN CM400 M.2 NGFF SSD Enclosure overheat in Kenyan weather?
The aluminium alloy shell of the UGREEN CM400 M.2 NGFF SSD Enclosure pulls heat away from the drive, so it needs no fan. That matters on a hot afternoon in Mombasa or Kisumu, or in a vehicle parked under the sun during fieldwork. The metal will feel warm during a long copy, which shows heat leaving the drive as intended. The sealed body also keeps out the fine red dust common on upcountry roads. Avoid leaving it on a dashboard, since direct sun heats any electronics.
Who should buy the UGREEN CM400 M.2 NGFF SSD Enclosure, and who should skip it?
Buy the UGREEN CM400 M.2 NGFF SSD Enclosure if you own an M.2 SATA stick from an upgraded laptop and want a rugged pocket drive from it. It suits engineers, photographers and consultants who move files between offices. Skip it if your drive is NVMe, because it will not be detected at all; an NVMe enclosure is the right buy. Skip it too if you own a 2.5-inch disk, which fits the UGREEN US221 2.5-Inch SATA Hard Drive Enclosure instead.
Does the UGREEN CM400 M.2 NGFF SSD Enclosure work with my laptop, phone or Mac?
The UGREEN CM400 M.2 NGFF SSD Enclosure works on Windows 10, 8, 7, Vista and XP, plus macOS, Linux and Chrome OS, with no driver to install. The included cable has a USB-A plug, which fits most office desktops and older laptops. For a MacBook or a phone with USB-C only, use a USB-C to USB-C cable, sold separately. Android phones that support USB storage can open the drive with a file manager, handy for moving videos off a phone before a long trip.
How do I fit a drive into the UGREEN CM400 M.2 NGFF SSD Enclosure?
Slide the inner tray out of the UGREEN CM400 M.2 NGFF SSD Enclosure, push the drive into the M.2 slot at an angle, then press it flat. One of the two rubber fasteners in the box holds the free end in place for shorter drives, so no tiny screw is needed. Slide the tray back into the shell and plug in the cable. A blank drive must be formatted before first use, through Disk Management on Windows or Disk Utility on a Mac.
Is the UGREEN CM400 M.2 NGFF SSD Enclosure safe to use during a power cut?
Running from a laptop battery, the UGREEN CM400 M.2 NGFF SSD Enclosure carries on through a KPLC outage because it takes power from the USB port. On a desktop without a UPS, the power loss stops the drive mid-write and can damage the file being copied. Keep important backups to a laptop or a machine on backup power. Always use the eject option before unplugging, especially in offices in Industrial Area and Eastleigh where power dips are frequent during working hours.
Technical Specifications
Core Function
- ASM225 controller — the chip that turns the drive's SATA signal into USB, so any computer reads it as storage.
- USB 3.2 Gen 1 at up to 5Gbps — a 4GB movie file copies across in well under a minute with a SATA stick.
- UASP ready — a quicker USB storage protocol that reduces pauses when copying many small office files.
- USB-C socket on the enclosure — a reversible port that also accepts a USB-C to USB-C cable for newer laptops.
- Bus-powered — the USB port runs the drive, so no charger or wall socket is involved.
Compatibility
- M.2 SATA drives with B-key or B+M key — the NGFF format used in many ultrabooks before NVMe drives took over.
- 2230, 2242, 2260 and 2280 lengths — the numbers give drive width and length, so 2280 means 22mm by 80mm.
- Capacity up to 2TB — around 680,000 12MP photos at about 3MB each, or years of documents.
- Windows, macOS, Linux and Chrome OS — plug-and-play support with no software to download or install.
- Not compatible with NVMe M-key, PCIe AHCI or mSATA drives — check the drive label before you buy.
Build
- Aluminium alloy shell — the metal body works as a heat sink, cooling the drive without a fan.
- 119 x 37 x 12 mm footprint — slim enough to ride in a shirt pocket or the coin slot of a laptop bag.
- Sliding inner tray — the drive sits on its own carrier, which keeps the slot aligned while you fit it.
- Rubber fasteners in place of screws — holds the drive end firmly with no screwdriver and nothing tiny to drop.
- Sealed enclosure body — keeps dust and moisture away from the drive's contacts on the move.
Inclusions
- One UGREEN CM400 M.2 NGFF SSD Enclosure with its aluminium shell and inner tray.
- 50cm USB-A to USB-C cable — reaches from a desk port to a laptop with room to spare.
- Two rubber fasteners — secure drives of different lengths inside the tray.
- Drive not supplied — the enclosure arrives empty for the M.2 SATA stick you already own.
- No adapter or software needed — the kit works straight from the box once a drive is fitted.
