The XO laptop has 1 MMC/SD slot. Testing confirms it supports a 4-gigabyte memory card. It is reported that it also supports an 8-gigabyte card.
From one of the FAQ's:
In today's market, SD cards can reach up to 64–128 gigabytes. Will this OS recognize these sizes?
- Yes. SDHC works. 8-gigabyte cards have been tested. As larger cards are created, they will also be tested. -gnu
- This came up on IRC, so I'll add additional details from there. XO uses a custom microchip for SD card access, Camera and Flash Enabler, or CaFE. CaFE includes SDHC support. SDHC is compatible at a hardware level with SD. Pierre Ossman wrote the Linux driver support for SDHC. SD cards up to something like 256 GB should be supported. Existing sizes have been tested on OLPC and work. MitchellNCharity 22:02, 14 November 2007 (EST)
- More: cafe is driven by the sdhci driver. cafe follows the standard host controller interface for SD controllers. MitchellNCharity 14:19, 15 November 2007 (EST)
