A systems engineer has quadrupled the maximum possible storage on a Raspberry Pi Compute Module 4. By default, the CM4 is available with up to 32 GB of eMMC flash storage, but Ivan Kuleshov has demonstrated that 128 GB is possible.

The Raspberry Pi Compute Module 4 (CM4) offers better performance than the Raspberry Pi 4 Model B and comes with built-in eMMC storage. However, the Raspberry Pi Foundation only offers the CM4 with 8 GB, 16 GB of 32 GB of storage, which is not much of a range to choose from, in our opinion.

Ivan Kuleshov, a systems engineer, has managed to install a 128 GB module though, bypassing the need to use a microSD card for more storage. According to Kuleshov, the larger eMMC module delivers up to 70 Mbps sequential write speeds and 80 sequential read speeds, or about double what a microSD card can do in a Raspberry Pi.

According to Tom's Hardware, Kuleshov used a Toshiba THGBMHT0C8LBAIG, which can be picked up for under US$45. The shortage of CM4 units with 8 GB of RAM has also led Kuleshov to use an 8 GB module from a Raspberry Pi 4 Model B. Unsurprisingly, we would not recommend upgrading the RAM or storage on your CM4 unless you know what you are doing, as Kuleshov evidently does.
