Looks almost exactly like a mini pcie card that most wireless cards take the form factor of.
It would be pretty sweet if they would make these so that tablets could be user upgradeable :)
Wow that little bitty PC-X card is a HD REALLY I cannot wait to seem them get into smart phone/tablet ultra small devices!
For those not familiar with mSATA, it’s a industry standard developed by the Serial ATA International Organization (SATA-IO). That’s a consortium dedicated to sustaining the quality, integrity and dissemination of serial ATA (SATA) technology.
Basically mSATA takes the electrical specifications of the regular SATA interface and incorporates them into the mini-SATA form factor. So physically it looks like Mini PCI Express, but they’re two different interfaces.
Specifically the JEDEC MO-300 defines the dimensions, layout and connector position for very small form factor (50.8mm x 29.85mm), or in other words cards fitting MO-300 match up to full size Mini PCI Express card size. However the mSATA specification allows for other form factors as well but the standard full size Mini PCIe standard sizes are basically the easiest to add to most systems.
While the standard has been around for a few years now it is only now starting to really catch on. The main limitation is that most are still limited to SATA II but SATA III cards have been made for high speed solutions...
Though the variance of its adoption also means you have to be careful to make sure the card you get is actually compatible with your system as not all will provide enough space for all size cards to be used.
Btw, there are a handful of systems already using mSATA drives. Like the Asus EeePad EP121 Slate PC for example.
Just be careful as there are other types of SSD's that also use the Mini PCIe form factor, such as the proprietary Flash_Con, replaces PCI bus pins with SATA and PATA, type originally used by the early Eee PC netbooks and some others like the discontinued Dell Mini 9. Along with PCI bus based cards like Super Talent fairly recently produced for the Mini PCIe form factor.
