It is hard to detect a RAM drive with any certainty. They look like a (fast & small) but otherwise normal looking hard drive to the operating system.
They don't support 'SMART', but neither do many other real hard drives.
Can't easily set a speed limit as the high end SSDs are getting close to low end RAM drive speeds. Especially the PCI-E based SSDs.
.....Fair do's, yes I realised just how hard it would be to detect after I had posted my suggestion, IE: a Newer PCIe IODrive or highend SSD v a PC100 (or the likes) Ram Drive....
Anyway I have to say I was really impressed with your Ram Drive utility I have now just slaughtered the highest Disk Mark score 73,000+ and the highest i5 Pass Mark result also, plenty of room to spare too as I only did a mild RAM OC and lowered the xMulti' by 1, the rest was made up by the Ram Disk
There is no reason that 10 years from now all hard drives will be solid state & as as fast pure RAM drives. The distinction between a hard drive storage and RAM should disappear in future computers.
.....Very true, I was looking at a fusion drive, until I saw the cost , but it's like anything non mainstream the cost is always hgh at first, I remember paying over 200GBP for a 1x CD Writer, now 52x drives are ten a penny!
