I've been in the market for an SSD external drive. After researching the heck out of TB and USB 3.0 SSDs, I've found that a lot of the time, the 3.0s are faster than the thunderbolt. I don't understand how this is possible, or why it happens. I'd like to know, what is the advantage of a TB SSD over a USB 3.0 SSD if the speed are close, of faster on the USB 3.0? Personally, I have been debating 4 options. (all around or at 512GB) 1. The Samsung T1 (USB3.0) 2. Samsung 850 Evo in a USB 3.0 enclosure with UASP 3. Transcend StoreJet 500 (TB/USB3.0) 4. Transcend JetDrive 520 (USB3.0) There was also the option of buying a TB HDD and replacing the HDD with the Evo, but the cost and speed will be similar to the other choices. So all of these, after watching Youtube reviews and doing a ton of research, are right around 400MB/ps. So naturally, this tells me TB is pointless. If this is not the case, why not? Thanks. EDIT: I will be using one of these to store libraries for music production. Kind of like how videographers edit the video stored on a hard drive. Also, is it true that thunderbolt transfers consistently, while 3.0 transfers in packets? If so, will this effect the fact that I will need to read sound libraries off of the external drive?
