I have a 2big 6tb Lacie HDD. It´s the last time I´ll buy a Lacie product ever again. They are expensive and usually not so good. My previous HDD d2 broke by a small tip to the side. My 2big thunderbolt drive has a loud noisy fan. I hate that my external drive makes so much noise that I don´t benefit anything from the Silence of my new iMac. I´ll gladly toss my 2big in the bin and buy a new HDD - Sadly none of those few thunderbolt HDD´s that exists give any info of fan and sound. Does anyone here have any experience or know a good thunderbolt HDD that is silent ? I can´t buy a SSD, its not enough storage, so it needs to be a regular HDD.
