Samsung 850 PRO (1TB) is more expensive at $437.13 than T5 from the same Amazon reseller. Most importantly, they are different products. External drives are usually more expensive for the same specifications, for obvious reasons, since they carry extra electronics, case, cables, etc. LaCie used to sell internal Samsung SSD as portable ones for two to three times more price. Go figure...
And, as said, T5 model (1TB) is 15.92% cheaper than T3. That is unexpected for a brand new product that is much better and usually starts selling at higher price.
Sure, price will come down with time, as always happens with electronics, but that will take time, since there is no real competitor of T5. That is the real big problem here and the main reason larger models (4TB, 8TB and even 16TB) have not been released. Samsung said all those sizes were possible with current V-NAND technology. Hopefully this situation will change soon.
