[QUOTE="HTPCSourcer, post: 1170639, member: 74879"] Each drve is likely to consume approx 3-4W more when running - let's assume +20W for your six drives, which are now up 100% of the time instead of maybe 20%. In total we are then looking at an additional consumption of 0.80 x 20W x 24h x 365 = 175 kWh - in Getmany the equivalent of 50€, but th depends on your local tariff. Regarding the life-time, it might actually be beneficial to not power up and down the drives as electric wear-out happens at power-up rather than during use. It is difficult to judge if the total runtime will shorten the life-time. In any case modern SMART parameters will at least give you sufficient heads-up that the drive may become faulty.
