looking for opinions on the following. running windows 8.1 and have 3 120GB SSD's in raid-0 for my OS drive and 12 2TB drives for my storage. there are programs out there to make ram drives so i was thinking of running a 1.5GB ram drive for temp files so as to off load all that random read/write off my SSD's. thoughts on that as far as performance boosts go?

secondly i was thinking of using cache programs to create a 512MB HDD cache for my platter drives out of system ram. thoughts on performance boosts there?

thanks.

Max speed on a typical ssd is 600MB/s read/write. My ram when not overclocked gets 2000MB/s read/write. Lets just say huge increase in speed. then again I'm in quad channel and i expect you are in dual channel. Youd probably get around 1500MB/s if not better.

sure thats on paper but was also curious about real world. my SSD gets 872 read and 717 write at present. my ram gets 12,351 read and 13,962 write. all MB/s

i may do some before and after benches and just try it. i had done it years ago but never really documented what did or did not work. i do recall that i had issues installing things as windows wanted to use hte ram drive for temp files but i was not large enough. we shall see.

Performance can be "based" off of that. Im using my RAM speed because yours seems not correct at all.

2000 / 872 = 2.293577981651376

It would help quite a bit. 2.29x faster at whatever it is you are doing with it. How much RAM do you have? Seeing as I have 40gb i never have to worry about maxing out or having performance drops unless i make an outrageous sized partition like 32gb.

im running an older computer so im limited to 16GB. its clocked at 2133Mhz so its decently fast. nothing like the new stuff that clears 20GB/s read/write but i dont see any reason to upgrade.

im not sure what your ram speed comes from but 1500MB/s is like DDR-200 speeds from 2000?

next block of free time ill do some testing, both bench mark and real world to see what difference it actually makes.

In my sig. DDR3-2133. Low latency and 1.5V. Please tell me about your 20GB/s because i doubt it (not trying to be mean).

And i mean yea its 20gb/s when being normal RAM. But when its being used as a RAM drive its around 2000MB/s. Download Passmark from http://www.cpubenchmark.net/ and setup a ram drive. tell me your speeds.

i feel like there is a major disconnect here. you stated that you get 2GB/s read write on your ram and you have 2133? 2GB a second is like 2002 or 2004 at best ram speeds, id expect to see that out of higher speed DDR1 ram. are you sure your measuring your speed properly? my ram does not hit 20GB/s as mine is older but many brands and speeds have cleared that 20GB/s speed, its fast to be sure but not a large barrier to be broken. i do not believe you could even clock your ram down low enough to get such a slow speed if you tried.

here is a random link i pulled from google where ram is clearing the 20 mark: http://www.modders-inc.com/g-skill-ripjaws-x-2133mhz-ddr3-ram/4/

edit: so i just searched quad channel and 40GB/s seems to be the standard for over clocked ram. your numbers are most defiantly off.

While using it as RAM i get Read Cached: 26440MB/s Read Uncached: 12460MB/s Write: 11689MB/s and Threaded operations: 36303MB/s. This is while having iTunes and Chrome (8 pages) open as well my everday clock of 1866Mhz. But as far as a Ramdisk goes my Read: 1799MB/s Write: 1805MB/s Random: 1891MB/s at the same settings.
