Are ramdisks the next SSD?
>Having a ramdisk without any form of internal battery to prevent massive data loss in case of critical failures.
Just buy a optane instead you nigger.
he fell for the 16GB RAMDisk RAM meme
raid adapters for m.2 SSDs exist you dipshits
With this kind of logic we should just put drives on the L1 cache!!!!!1!11!1
holy balls
No.
These things are ancient news and will never be viable until RAM is $0.16/GB at least.
>Barely 1GB/s write and slightly over 2GB/s read performance on non-sequential storage
Useful for dumping things INTO memory, not even comparable to a RAMdisk
>Ram disk
>micro sd raid
>some other thing on the left
The fuck is that card?
You DO know that's just 4x nvme raid 0, right? Threadripper has supported 8x nvme raid 0 for a while now and we could see 16x nvme raid 0 in future threadripper successors.

Not that anyone would do something this stupid anyway, i'd probably just improve load times by like 100ms at this point from 1x nvme.
Aside from the absolutely heinous cost of putting together an 8x NVME RAID 0, and then the absolute lack of security of using RAID 0 nonvolatile storage as a rapid data point (which means frequent offloading from one storage point to another, which means tying up disk access, which...etc you get the point), the issue isn't really "It's only 4x", it's more "that's very impractical"
A single PCIe SSD is great because its just a drop-and-go procedure, no RAID bullshit, just really really fast storage. But it's still nothing compared to keeping things floating in RAM.
Tying that storage to extend RAM is a huge system clusterfuck and a giant pain in the ass, so it's only valuable for sustained, large, one-time-pull-or-push operations.
People working with these sized data sets are not doing that, they're making a whole ballfuck of large sized random read/write operations.
Why else do you think database servers always have 10 kajillion GB of RAM? Just load database records into memory and persist them for updates or idempotent operations and only release them after X many seconds.
Optane is unironically the best fit for "really big really fast memory pool".
