Crucial "Momentum Cache"

[siyangqiu]

I updated Storage Executive and found this new tab about "Momentum Cache". It seems that it caches disk writes to RAM before transferring the SSD for performance and longevity. However, I wasn't able to find any reputable reviews or articles on this and it's been a month already, so I'm wondering if anyone knows anything other than the obvious here.

It is just an SSD cache that uses ram to store data. All unused ram space is used and when required frees up the memory for programs. One thing I noticed it, there is a lot more pagefile swapping going on because of memory allocation requests and when you go back to another program it has to be reloaded from the pagefile so there is a pause.. But the cache does speed up data reads/writes.. The doc says it has to be the boot drive but I booted off a hard drive and did a test and noticed the SSD was still being cached. I would have liked a little more freedom and control for the user.. But its better than nothing.

It is a software solution similar to Samsung's RAPID. It does have it's perks and restrictions tough, and I wouldn't recommend it unless you have a specific workload that demands it. Another benefit other than those mentioned might be lowered write amplification.

To put it bluntly, for office work and gaming you will not notice a performance boost if you enable it.

From the document you linked:

Enabling Momentum Cache leverages random access memory (RAM) to increase performance. Data stored in RAM is volatile and therefore at risk of being lost in the event of system power loss. Having a battery-backed power source is strongly recommended to reduce the risk of data loss in the event of unexpected power loss. Data loss may occur in the event of a system crash, such as a blue screen fatal system error.

Now queue in the Primo Cache advice.
