The mSata Design only uses 4 or 8 pieces of NAND flash and is used in limited space. A 2.5″ SSD usually uses 8 or 16 Pieces of flash depending on capacity. Given the same controller on an mSata and an SSD, Sequential write speeds will be about 100–200 MB/s faster on the 2.5″ SSD.Given the same controller on an mSata and an SSD, Sequential write speeds will be about 100–200 MB/s faster on the 2.5″ SSD.
I sold solid state drives for a few years and the speed difference is staggering. I do agree that M.2 using the NVME standard is the way to go if you want a smaller drive. NVME uses the PCI Express lines and can transmit at up to 2GB/s (so long as the drive can handle it) where as SATA caps out around 500MB/s (effective transfer rate).
