In terms of the internal eMMC Flash storage, the Librem 5 writes faster than the PinePhone, but reads slower than the PinePhone. The [best eMMC 5.1 drives](https://www.androidauthority.com/samsung-emmc-5-1-flash-memory-588143/) achieve sequential reads of 250 MB/s and sequential writes of 125 MB/s, so the internal storage of both phones is significantly slower than a normal smartphone. The eMMC drives in both phones support the [eMMC 5.1 standard](https://en.wikipedia.org/wiki/MultiMediaCard#eMMC), but the [A64](http://files.pine64.org/doc/datasheet/pine64/A64_Datasheet_V1.1.pdf) in the PinePhone and the [i.MX 8M Quad](https://www.nxp.com/docs/en/data-sheet/IMX8MDQLQCEC.pdf) in the Librem 5 only support the eMMC 5.0 standard, which is a little slower in sequential writes and random reads.

The 32GB Kioxia (formerly Toshiba) [THGBMHG8C2LBAIR](https://www.mehrinfo.net/toshiba-emmc/1266-thgbmhg8c2lbair.html) in the Librem 5 and the 16GB Kimtigo [KM111SS0016GxA-DDD00WT](http://files.pine64.org/doc/datasheet/pinephone/Kimtigo_fbga153_16_32_64_eMMC_datasheet_v1.3.pdf) in the PinePhone should be able to support higher speeds. Kioxia doesn't publicly release the data sheet for the THGBMHG8C2LBAIR, but the data sheet for its larger 64GB variant, the [THGBMHG9C4LBAIR](https://www.glynshop.com/erp/owweb/Daten/Datenblaetter/DRAM_FLASH_MEDIEN/10_Nand%20solution/05_Toshiba/01_Datenblaetter/01_Original/eMMC/eMMC_15nm/THGBMHG9C4LBAIR_15nm%2064GB%20e-MMC%20supreme%20ver%205.1_E_rev1.1_150709.pdf) lists higher speeds for the chip.

It is unclear at this point, what is holding back the performance of the eMMC drives in the two phones.
