256GB is way too small. The price for the 256GB device was in my price range and I still did not know how beneficial it was so I tried it. It was amazing, but I just didn't have enough space. You never understand how much space a project can take up until you have almost no space available. I had to basically use the SSD as a bridge whenever I filled its capacity. Nonetheless, I still enjoyed the product from SanDisk, but the size is just too small and the prices are too high. I guess that's the price you have to pay for an amazing product. I have an external hard drive, but it is a hard disk drive. It's not bad at all but if there were an external solid state drive that would be amazing. The speed and portability of it would be incomparable. I would have the efficiency of a 2015 MacBook in the form of a portable drive. The only problem I might run into is the price of this external solid state drive. Replacement SSDs are priced at $90-$120 for a 256gb if it's external, it might be 30% more.
