i just use imdisk and it is fast. i cant say if dataram is better but i doubt performance would be that much better to be even noticable.. dataram may have more features tho but i am not sure as imdisk worked well for me smile.gif

If you can find one of these and if it performs near as well as the main board controller/slots, it fits your wishes, I think, and has a battery backup for when you shut down, although i imagine replacing it would be annoying (old proprietary rechargeable batteries always are).

Well I downloaded the free version of dataram and I plan to download IMdisk and run benchmarks on each. I realized that if I can learn imdisk without much issue, I can easily do a benchmark myself that tells me about my system. I'll post results if I do the test. smile.gif

Did have one of those. Unfortunately, you're limited to SATA1 speeds and I believe it only supports up to 4GB RAM. Either that or 2GB DDR RAM modules were prohibitively expensive. Would love to see a PCI express x16 version supporting DDR3, alas, there are now several software-based RAM disk solutions that a physical RAM disk solution like the iRAM is unlikely to be released.

So why do you need more than 32gb? I bought 32 for future overhead and a 20 gig ramdisk but honestly, that's a lot. lol. I'm just hoping I can utilize a lot of it. Now if you want to leave your PC on 24/7 with a UPS as backup, I could see any number of program installations being awesome on more than 32gigs... biggrin.gif Have one SSD for image writing on shutdowns perhaps...then HDDs

Want to run virtual disks on the RAM disk (~10-20GB per VM) while still having enough RAM to allocate to the virtual machines. Disk images will be flushed to an SSD RAID-0 (SATA III) at shut down. I'm estimating it'll take around 1 minute per 20GB at a conservative estimated transfer speed of 500MB/s. A couple of VelociRaptors in RAID-1 (SATA II) will be used for back-up. If I create a 200-400GiB partition for virtual disk backups, I reckon copy speeds should be around 150-200MB/s or around 2-3 minutes per 20GB.

Mostly PHP+MySQL development and some test environments. In answer to your previous post, yes, I do leave my PCs on 24/7 and I do have a UPS for back-up. However, strongly considering upgrading the current UPS (CyberPower 1500 PFC) to something a bit more robust (SURTA1500XLJ + SURTA48XLBPJ extended batteries) to give sufficient time for array rebuilds (UPS also powers my 12TB unRAID server).

Nah. That's way too small for pr0n. tongue.gif I'd like to have Murlocke's servers for that. wink.gif
