Hard to say exactly how warm. But i am using it with M1 mac as an audio sample and video storage hard drive for music and video production. when im editing videos where the raw files are on the T7 or working on a big music project and playing the project where samples on the T7 are being played every second, it gets noticeably warm. i wouldnt even say VERY warm. i also never really held an SSD under heavy use to test for temperature lol. And they say T7 gets warm because its NVME and not Sata. Definitely not painful to touch and i would definitely not call it "hot", my old 2019 intel macbook pro would actually be almost painfully hot if i left my finger close to where the monitor hinge at full CPU load. Is it okay since the body is metal and i guess its one big heatsink? or should i be worried about longevity and lifespan when Ableton for example is constantly reading (not writing) maybe 2-8mb/s? for hours a day? thinking about returning it and getting T5 people say it doesnt get warm although its more than twice as slow as the T7 i have now.
