There’s a bit of a performance difference between the two options. So if price was the more important then I would just get the needed cable and mounting screws and install the 2.5” drive. If performance is the most important then get the blade SSD. But that may not be the best answer as you killed one SSD already so it sounds like you have a bit of data churning which is an issue with SSDs in general. If you can buy at least 50% more of storage, or setup a dual drive install putting in both SSDs! Here the blade is the boot drive and holds you Apps. Your data and media sits on the SATA drive getting the max performance your system can offer.
