So, consider these carefully when you decide whether you want to do this or not. This might not be a high priority for the average Raspberry Pi home user, but in commercial and embedded uses the reliability and durability of micro-SD cards can be an issue. Get rid of the micro-SD card altogether.The problem is that the Pi-Desktop add-on board connects to the Raspberry Pi via USB 2.0, which has a maximum data rate of 60MB/sec. This might seem strange at first glance, because mSATA speeds (~500MB/sec) are roughly five times faster than micro-SD (~100MBps).

This is probably the worst reason, and if it is your goal you are going to be disappointed. Improve performance of the Raspberry Pi.Prices for equal capacity are consistently lower for mSATA than microSD. The largest microSD card I have seen so far is 400GB, while mSATA drives up to 1TB are available, at a price that is only about 25% higher than the 400GB microSD. This is probably the best reason, and it really does pay off. Increase disk space, at a better cost than comparable micro-SD cards.The first thing to consider, though, is why you would want to do this. Now I am going to look at one of the optional expansion possibilities of that kit, adding an mSATA SSD (Solid State Disk). I limited that post to the basic installation, configuration and use of the Pi-Desktop enclosure itself. In my previous post, I wrote about assembling and using the Farnell element 14 Pi-Desktop kit.
