Speed comparison? Thunderbolt SSD v Fusion Drive
Last year I purchased an iMac (Retina 5K, 27-inch, Late 2015) with a 1 TB fusion drive. Would an external thunderbolt SSD be faster than the internal fusion drive? I'd like to use it as my primary drive. Also, does it matter which version of the thunderbolt enclosure I buy?
