So you mean that its really no use of having RAMDisks in latest SSD's and instead use the default settings? How did you come to know this? Was it just a myth that of RAMDisks?
Early SSDs had decreased life-span. There were problems with too many writes. Over the years it was recommended to write browser cache to RAM Disk for increased SSD longevity, security and speed up browsing (HDD).
RAM Disk is still good for security, but I can just use Shadow Defender which allows entire virtual session cache to be written to RAM. I use Shadow Defender on-demand.
Honestly, I see no real advantage to RAM Disk except for HDD = it will speed up browser loading and surf speed. On SSD, RAM Disk will very likely not increase browser load and surf speed. In fact, it might slow it down a bit. Depends upon system and SSD drive.
I am neutral on RAM Disk use. It is good for security. Can add Sandboxie sandbox to RAM Disk.
However, since I removed Sandboxie, I no longer have any real need for RAM Disk... at least not to me personally. Others may feel and think differently...
