Using an average Micro SD card will generally only only last a year or so before you have problems. Even with the higher endurance cards, you might get 2 -3 years. So, what’s a better long-term solution? Solid state drives (SSD’s). Fortunately, a Raspberry Pi is designed to boot from a USB port using an SSD – read how.

After you set your Pi to boot from USB you can use any SSD: including inexpensive mSATA drives – like these. And, put them in an optional enclosure – like these – just make sure that the speed of the enclosure matches that of the SSD.

Once you have that setup, you will need to either burn your S.A.R.A.H. image to the new SSD using Etcher, just like you did during the install process. Or, you can make a backup of your image existing Micro SD card – here’s a nice write up how.

With your Micro SD card backed up, you can now burn that image onto your SSD using Etcher. You can find the instructions here.
