Under normal operation the system is whisper quiet. Stressing the system to its limits produced 36.8 dbA making it noticeable but never annoying or intrusive.
Exccellent – I like it – especially the RAID performance!
Really good performance results. I dont think 80c is too high. 85c is cutting it close though. Interesting to see dual SSDs being used a lot more now, which is wise as it is critical to an overall system performance result.
