The future of Mac – and PC – interfaces is headed towards the single, unifying Type-C connector for the majority of computer peripherals via a 40Gbps ThunderBolt 3 or a 10Gbps USB 3.1 Gen2 Port. As more Apple and other computers embrace this standard, we’re seeing the market split between expensive and fast, high-bandwidth peripherals that NEED Thunderbolt 3’s transfer rates, and far more affordable USB-C devices that are ‘fast enough’ for many consumers. Case in point: Cheap, Fast SSD USB-C drive options galore.
Off the shelf USB-C SSD Mac backup drives are downright cheap compared to their Thunderbolt counterparts. For do it yourselfers, you can cobble your own DIY SSD USB-C drive with either dirt cheap SATA III SSD drives and a USB 3.1 enclosure. For speed freaks, your best ultra-fast but cheap option is a USB 3.1 SSD enclosure that supports PCIe NVMe SSD blade modules which will perform about 30% faster than SATA SSD drive options.
