Delay write from L2 cache until laptop plugged in

Post by locketine »

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.
