Ssd dram

[Mii Cube]

I found a amazing deal on a m.2 ssd but it lacks a dram cache, is there a way to use system ram for that purpose or should i spend more on one with it on the ssd

You can manually enable "write caching" to use some system memory (RAM) as a write to improve performance.

 

It should be enabled by default. If not you can go to Device Manager, select the drive from Disk Drive section, right click and select Properties then Policy tab. Tick the check box "Enable write caching on the disk".

 

Keep in mind this method may only improve the performance slightly as DRAM-less SSD are inherently a bit slower than their DRAM-equipped counterpart, but in day to day operation there should be any noticeable differences except extreme edge cases, and any SSD is far superior than a traditional mechanical drive.

Some drives have a HMB to use system ram like dram, but its automatic and won't need to be setup.

 

But dram doesn't matter that much, esp with nvme drives and there will be basically no performance difference for almost all desktop uses.
