Replacement for 2TB HDD Hitachi HDS722020ALA330
I recently upgraded my a. m. iMac with an SSD by replacing the SuperDrive. This exercise went very smoothly thanks to the excellent iFixit description (MANY thanks for that). I setup the new SSD (Samsung SSD 840 PRO Series 256GB) with my a. m. internal 2TB HDD from Hitachi as FusionDrive. Also this worked very smoothly and my iMac really feels almost like a new iMac again. However, I also realized that the Hitachi HDD remains a speed bottleneck and noise producer as before for any data not stored on the SSD. So I'd like to spend my iMac a newer, faster and if possible more silent HDD from a proven manufacturer but I always read I should only replace with the original manufacturer due to the famous thermal sensor issue. Problem is that Hitachi is now called HGST Storage and had been apparently acquired by WD. HGST only shows one remaining desktop HDD on their website, Deskstar 7K1000.C with just 500GB and 1TB and the opinions about that drive seem to be everything but positive. So my question - does anybody now a compatible HDD fulfilling my a. m. performance desires and without the need to turn my iMac to the sound level of a starting airplane due to continously running fans?
Many thanks in advance,
