Delay write from L2 cache until laptop plugged in

PrimoCache is great but my laptop battery life is suffering so I'm considering getting rid of it in favor of using my SSD as a primary drive.

Currently, I am using a smallish SSD (120GB) as an L2 cache for my large HDD (1TB), and I think that the HDD could idle more or even shut down entirely if the deferred write feature only flushed the L2 cache when the laptop is plugged into power.

I think such a feature would garner me 30 more minutes of battery life if this article is accurate. I also don't think that I would have to worry about data loss because the cache is on a non-volatile storage device.

Thank you for your suggestion!

Please note that so far the risk of data loss is same as RAM cache when you use SSD cache with Defer-Write. It is not recommended that you defer the writing for a long time. So I'm sorry that we will not implement your suggestion unless we have a breakthrough on ssd cache with defer-write.
