What's a good operating temperature for hard disks?
Well, decided to set the alert temperatures on my HD Sentinel configs.
By default HDS has the green setting set to 40C or less, yellow is between 40-50C, while red is above 50. I'm thinking these are conservative. My internal drives typically operate just below or just above 40C, even while idle. And they get upto at most 48C when really active. I have an external USB drive which is typically above 50 at idle, and is above 55 under mild loads; it will get above 60 under heavy load, but that's not what a USB drive is typically used for. So I'm thinking I'm going to set all the alert levels up by 5C. Instead of between 40-50C, it'll be between 45-55C? Think I'm taking too much of a chance? Yousuf Khan |

What's a good operating temperature for hard disks?
Yes the default ranges you described are conservative- but that's the
point. You normally want to keep the temperatures in a conservative range, & without huge temperature swings, to ensure heat isn't a factor in reduced life or reliability. So IMHO it is both conservative and fair. The operating temperatures you are experiencing are a little high for my taste. They seem to indicate that you're probably not using the greatest case, even assuming ambient room temp was a little high. USB drive boxes tend to not be super reliable or capable so I wouldn't be comfortable reproducing their operating conditions elsewhere. They seem to work best for me when I have a fan blowing on them, or they're open, and when I generally treat them with kid gloves. But there are multiple issues going on with those- temperature and jostling of the drives, as well as temperate of the USB bridge board. Are you taking too much of a chance? Right now I'm not aware of any really good statistical data about operating temperature and premature drive failure & flakiness so I don't really know. I have found though that operating HDDs in the mid 30's to low 40's (even under full load) is a range normally easily attainable and which yields satisfactory results. One additional thing to consider is the higher drive temps are often an indicator of higher temps elsewhere in the system. While the temp may be a little high but OK for a drive that may be a symptom of a problem elsewhere. Basically if the system is of any importance to you it's better to be conservative. The cooler and more stable the temp the better. |

Yousuf Khan Given that most drives have an absolute maximum rating of 55C, I think these values are not very conservative, but realistic. A drive that gets to 60C or above is inadequately cooled and may die early. My advice would be to aim for 50C or below for normal operation and accept peaks of up to 55C but not more. Arno |
