Quick Answer

Most 1TB SSD compatibility issues come down to motherboard NVMe slot generation, M.2 key type, and BIOS detection settings. Update your BIOS, check the slot supports your drive's PCIe generation, and confirm Secure Boot/CSM settings before assuming the drive is faulty.

Common Compatibility Pitfalls

A 1TB SSD not being detected almost never means a dead drive. The usual culprits in order of frequency:

  • BIOS is on an old version that doesn't recognise newer NVMe controllers
  • M.2 slot is wired for SATA only, but you've installed an NVMe drive (or vice versa)
  • PCIe lanes are shared with another slot, disabling the M.2 when a GPU is in slot 1
  • Secure Boot or CSM settings interfere with detection
  • Drive isn't seated firmly under its mounting screw

Before refunding the drive, work through each of these. A R1,899 Kingston KC3000 or Samsung 990 Pro 1TB is rarely defective out of the box.

Step-by-Step Fix

Start with BIOS. Boot in, check the storage section, and confirm the M.2 slot is enabled. If your drive is NVMe, the slot description should mention PCIe Gen3, Gen4, or Gen5 with NVMe support. If it says SATA only, you've got the wrong drive type.

Update BIOS to the latest stable release from your motherboard vendor. Many compatibility lists added 2024–2026 SSDs only via firmware updates. AMD AM5 boards in particular benefited massively from AGESA updates for newer NVMe drives.

Reseat the drive, ensure the standoff and screw are tight, then boot. Check Disk Management on Windows to initialise an unallocated drive. If it shows there but not in File Explorer, you simply need to format and assign a drive letter.

SATA vs NVMe Confusion

If you've bought an M.2 SATA SSD but your slot is NVMe-only, the drive will not work, and vice versa. Check the product page on Evetech for the exact spec, and match it to your motherboard manual's M.2 slot table. Most modern boards support both, but ITX and budget B650 boards sometimes restrict slots.

Frequently Asked Questions

My SSD shows in BIOS but not Windows. What do I do?

Open Disk Management (Win + X, then K), find the new drive, right-click and select Initialise Disk. Choose GPT, then create a new simple volume.

Will a Gen5 drive work in a Gen4 slot?

Yes, NVMe is backwards compatible. You'll lose the Gen5 sequential speed advantage, but real-world gaming performance is nearly identical to Gen4 anyway.

How long does delivery take from Evetech for a replacement SSD?

Joburg and Pretoria addresses see same-day or next-day delivery for in-stock SSDs. Cape Town and Durban orders typically arrive in 2–3 working days via overnight courier.
