PC Pro has investigated whether SD cards make a cheaper alternative to upgrading your SSD. The biggest problem is that SD cards have limited number of guaranteed write cycles before the card risks failing, so they’re best considered for storing files you don’t update often – a media collection, for example. Read and write speeds are also much slower than those available from SSDs. Nevertheless, "if you’re after only a quick boost in capacity for non-critical files, the sheer convenience of being able to leave an SD card in the laptop at all times makes it a great way to save money," PC Pro concludes."
