RamDrive join to SSD

[simbakkk]

Hello,

I have a question .

It is possible under Windows OS create 50gb RamDisk and join it with partition of 60 gb SSD?

Thanks Sinisa

This can be done with an extended volume. You need to convert your ssd and your ramdrive to a dynamic drive. I don't know which ram disk tool lets you create a ramdisk that can be converted to a dynamic drive. If you find one, tell me.

try VHD

@Chanix You cannot do that with VHD or VHDX.

If you get a good SSD and or raid them you won't have to do that.

On Windows you can do it using PrimoCache (Paid Software), https://www.reddit.com/r/chia/comments/np0e3x/the_difference_8gb_of_ram_cache_makes_using/ On Linux it can be achieved by using BCache. https://www.reddit.com/r/chia/comments/o16tsc/quick_tutorial_to_set_up_bcache_to_enable_ramdisk/

I created a 24GB block ram disk (only have 32gb system) with this command: "modprobe brd rd_nr=1 rd_size=25165824 max_part=0" which goes to /dev/ram0. Then also made 4 x 24GB partitions across my 3 SSDs. Raid 0 together all 5 with mdadm and it seems to work pretty well without running out of space plotting on the 110GiB temp2. The 2 SSDs with only a single 24GB partition I also Raid 0 together the rest of the space for the main temp dir. Getting equivalent speeds to before and estimate saving 15% of writes to my SSDs. Having 64gb of ram would be much better as you could go to 30-40% probably.

any body help me ive tried following this but am a completely new on linux

ive managed to create a 50gb ramdisk i can access thats the where ive got to

when i try to make-bcache -B /dev/nvme0n1p1 --block 512b --bucket 128k -C /tmp/ramdisk --block 512b --bucket 128k --discard --writeback

How about /dev/ram or /dev/ram0?

If you're limited to Windows, check out Primocache as it's really the best solution out there (albeit, not free). I'm a huge FOSS advocate, but Primocache is really quality and I've not found anything else near as good, free or otherwise.
