Re: L2 (Optane) R/W L1 100%R, Writes are too fast for RO!

Yeah, sure! Only going by the numbers of access time (higher than to be expected from Optane because of virtualization-overhead...) As soon as L1 (100% read) is activated, write is also absurd fast: Primocache.PNG For reference without L1, otherwise same config: PrimocacheL2only.PNG As I learned, da...

Re: L2 cache verification

In this regard, an option transparent to the user (e.g. journaled writes yes / no) would be perfect for a lot of applications, where a fast media (optane) can br written to and data integrity would be achievable in case of a power failure / system crash.

Re: L2 (Optane) R/W L1 100%R, Writes are too fast for RO!

Still have not figured out, how a 100% read L1 can enhance write speeds on CrystalDiskMark... Am I alone with this observation?

Re: Can't get writing caching to work.

Why not? It makes sense, as write caching with RAM is putting your data integrity at risk in case of a power failure... So making it default wouldn't be "good"

Re: L2 (Optane) R/W L1 100%R, Writes are too fast for RO!

Sure, but it's faster than optane, so I assume RAM is involved (which I set to 100% read!)
That's what I don't get.

L2 (Optane) R/W L1 100%R, Writes are too fast for RO!

Hello, as a new (trial) User I might get something wrong, but I am really confused: Preface: A VM (on proper Hardware & ESXi) has some unoptimized (closed source) code I cannot alter. So the idea is to improve (un)snappiness with Optane (900p) with PCIe passthrough. The default SSD (Raid 1, 2 SA...
