Mac mini 2024 (M4 / M4 Pro) Internal NVMe SSD Upgrade Module

Expand the internal storage of your Mac mini 2024 with a purpose-built NVMe SSD upgrade module. Available for both the M4 and M4 Pro models in 2TB and 4TB capacities, this module allows you to replace or upgrade the onboard removable SSD — giving you significantly more space and, in many cases, faster read/write speeds than the base Apple storage.

The PCB and connectors are engineered to mirror Apple's proprietary SSD module design exactly. NAND memory chips are sourced from the same trusted vendors that supply Apple for Mac mini 2024 production, ensuring compatibility and consistent performance. Every unit is factory tested before shipping.

Real-world speeds (user-reported): Up to 3.3 GB/s read and 3.1 GB/s write — faster than the base 256GB Apple SSD (typically 2.3–2.8 GB/s).

Important compatibility note: The M4 module and the M4 Pro module use different PCB designs and are not interchangeable. Select the correct model for your Mac mini when ordering.

Key Features

  • Purpose-built for Mac mini 2024 — available in M4 and M4 Pro variants
  • NVMe interface — up to 3.3 GB/s read / 3.1 GB/s write (real-world)
  • NAND chips sourced from Apple-approved vendors — full compatibility guaranteed
  • PCB and connectors precisely mirror the original Apple module design
  • 100% factory tested before dispatch
  • Available in 2TB and 4TB capacities

What's in the Box

  • NVMe SSD upgrade module (M4 or M4 Pro, as selected)
  • Mac mini opening tools: jimmy + prying tool
  • Screwdriver set: Torx T3, T5, T8

Before You Install — Read This First

  • Back up your data first. Due to Apple's security architecture, data on your existing SSD cannot be recovered after the new module is installed.
  • DFU restore required. After installation your Mac mini will enter DFU mode and requires a firmware restore from a second macOS device (Intel or Apple Silicon, 2015 or later).
  • Opening the case involves prying off the bottom cover with the included metal tool — minor cosmetic marks on the bottom edge are possible but not visible during normal use.
  • Keep your old SSD. If you need any Apple warranty service, swap the original back in first.
  • Installation takes approximately 10–20 minutes. Full step-by-step guides: DIY Guide | iFixit Guide
  • Interface: NVMe (Apple proprietary form factor)
  • Capacities: 2TB, 4TB
  • Compatible models: Mac mini 2024 (M4) | Mac mini 2024 (M4 Pro)
  • Not compatible with: Mac mini Intel, M1 (2020), M2 (2023) models
  • Installation manual: Download PDF
