Not volatile, but Optane? Even in the era of super fast pcie4 ssds, the random read times for optane is like 6-10x faster. Fast enough that intel put optane into ram module for persistence.
Plus intel sold nand ssd drives (model H20?) that had a 32gb optane module on board. You can just use the optane for swap and the nand as your main drive.
- favorited 4y agoAlso, consumer Optane is hella cheap at the moment. For example, : https://www.newegg.com/intel-optane-ssd-p1600x-118gb/p/1Z4-009F-00621 https://www.newegg.com/intel-optane-ssd-p1600x-118gb/p/1Z4-0...?
- samstave 4y agoQ: ; I have multiple TBs of SSD currently, how is Optane better at ~118 GBs of stuff... Why would I want this over that?
- 0xCMP 4y agoIf you're doing lots of writes it will not wear out the same way an SSD would. Also it's very fast, but these days not as fast as the best NVMe SSDs you can buy now.
- FpUser 4y agoOptane has insane write endurance. Speed is good as well. It is expensive for sure but I guess it can be justified for some database use.
- wongarsu 4y agoI think of optane not so much as a mass storage device, and more as a fast scratch space. The perfect place to put your swap partition, to use as cache in front of slower storage, the scratch space of an algorithm that starts using disk space to save memory, or the intermediate output of your compiler.
- TomatoTomato 4y agoOrders of magnitude better wear capabilities and much faster at low queue depth operations
- paulmd 4y agoMuch lower latency. Optane doesn't have any of the "page" / "cell" bullshit that flash imposes, so there's really no need for buffers at all. Writes just go straight to disk basically, at almost zero latency, NVMe itself imposes much more latency than the actual reads/writes.
