While Solid State Drives (SSDs) are most commonly used today, old mechanical hard drives (HDDs) refuse to die and now they survive submerged in water to improve their performance.
We have explained on several occasions that the only advantage of hard drives over SSDs is storage capacity, otherwise they are behind in the race.
One of the disadvantages of HDDs, as recalled by a report published on the website of hardzone, is the heat and high temperatures generated by rotation. Fortunately and curiously, there is a solution to this problem and the secret ingredient is water.
How to avoid the death of your hard drive with water?
Big companies like Iceotope they are working on an immersion liquid cooling system. It does so with the collaboration of Meta.
The companies published a study on this new technology, which is based on a 40U rack containing 72 HDDs connected to two SAS expansion cards and NIC network nodes.
According to the data, all 72 hard drives were operating about three degrees lower than in over-the-air systems, regardless of their position in the system. The interesting thing is that the water temperature never exceeded 40 degrees.
The best data is in consumption, since a 5 percent power consumption reduction with respect to an air system.
Iceotope stressed that the system is safe and that the HDDs used in data centers use fully sealed helium chambers, which prevents coolant from seeping into the unit and damaging it.
