Re: How does 100% Read Cache work...?

Got it about the reads. Thanks.
If you don't mind, would you kindly clarify further on the writes? It might help me better understand the occasional performance problems I'm observing and figure out what to do about them. So: with 64kb block size in underlying hard drive, 512kb PrimoCache block size and Windows/App writing various sizes, typically from 1kb to 4kb. With Defer Write enabled and, for example, with Native mode and a 90sec interval and assume PrimoCache accumulated about 1GB of deferred write data. Also assume little to no fragmentation on the hard drive. How would PrimoCache try to "organize" the data it writes at the 90 second interval: will it try to write 512kb at a time? Something else?
