M4 Mac Mini : Storage Expansion Module (2TB / 1TB)

Important Update on 2TB NAND Availability (28th Dec 2025)

Unfortunately, 2TB SanDisk NAND is currently unavailable from all vendors we work with. Based on vendor feedback, production of this IC has been temporarily halted, and availability is uncertain at this time.

At the moment, Kioxia NAND is the only alternative, but it comes at a significantly higher cost due to limited supply & cross compatibility with iPhone 16 & 17. Please proceed with purchase only if you are comfortable with the higher price.
We will update this page immediately once SanDisk NAND becomes available again.

FAQ:

1. Will installing this SSD void my Mac Mini’s warranty?

• Technically, if the upgrade is done cleanly and without any visible traces, it shouldn't void your warranty. However, Apple’s warranty policies are subject to their discretion, and Apple's EULA stated that their hardware must be used with the original hardware. 

2. How long is the warranty?

• This SSD comes with a 1-year warranty or 600TBW (1TB size) or 1200TBW (2TB size) (whichever comes first), ensuring reliability and peace of mind.

3. What is the difference between Kioxia and SanDisk NANDs?

• Kioxia and SanDisk NANDs are both reputable storage solutions, but they come from different manufacturers. While both brands offer high-quality NAND flash memory, some users prefer Kioxia for its proven reliability in enterprise storage, while others choose SanDisk for its widespread use in consumer devices. Ultimately, both options provide solid performance for SSD applications.
• Both of the NAND options use PCIe 4.0, so in terms of performance, they don't differ much. Max Speed depends on the size of the NANDs, and both have the same speed at any given size. 
• Max Speed for 2TB size is 4800MB/s (Write) & 2900MB/s (Read) - 1GB File size. 
• Max Speed for 1TB size is 4000MB/s (Write) & 2900MB/s (Read)- 1GB File size.
• Kioxia is a little bit more expensive due to wide compatibility also in the latest iPhone + Mac series.
