In my free time I tested a couple of cards and logged the results.Īll tests were done with the exact parameters: So with those assumptions in place, you would only use hardware raid where needed (because they aren't cheap), and should always have a backup card in storage. In case HW RAID card dies, you can't assemble the array without a replacement card. Given the choice, take the H310 over the H200.I was asking myself "What kind of RAID should I configure?" a lot lately. Don't count on 12V fans to start at only 5V.ģ. $20 non-contact thermometers are not particularly useful to measure spot temperatures of shiny components.Ģ. I was able to hold my finger on the heatsink without it being anything more than a little warm.ġ. Once running, the same disk speed test went to 33.0C. Or anything else, really.)Īdding 40mm, 12V, ball-bearing fan to H310 heatsink showed that the heatsink was one row of fins larger. (Donations of a Flir thermal imager cheerfully accepted. The highest temperature seen in a repeated test was 38.2C. Tilting the thermometer input one way gave 35.8. H310 after read-only speed test ( diskinfo -tv da0) on WD 750G drive (approximately 35 seconds): 31.8C Felt warmer, uncomfortably warm to a finger but not instantly too hot. Room temperature was about 23-24C.īoth tests with the heatsink alone, Gelid "GC Extreme" heatsink compound, one drive connected, approximately thirty seconds after booting FreeBSD ( mfsBSD), no drive activity. Also, the heat sinks are silver and reflective, so it would not surprise me if actual temperatures were 50% higher or more. Some numbers measured with a digital non-contact thermometer that is probably not too trustworthy for absolute values.
