hi Leifs,

I am thinking about a new machine to do my panoediting and previewing. rendering can be done on my i7 920 16 GB machine, but i need a faster machine to work at.
Wondering if it will be cost/effective and still superfast to buy six revodrives9some 120- some 240 gb) and put them onto a nice motherboard with 32 to 64 GB of memory. add a 4 gb 256 BIT GPU and presto.....?

like to hear your thoughts on it.

I know what it is, I have one.

I was not thinking about RAID, just use every revodrive as a single drive, according to the function 1 to 6 you mentioned.

i know about this issue whether or not the Revodrive can be used as a boot-disk, so maybe should use a normal harddisk or SSD for booting.

I have revised the plan and are for the time beeing running this setup:
1) OS - samsung 830 SSD  C:
2) OS pagefile - LSI SSD raid0 E:
3) OS temp - LSI SSD raid0 E:
4) APG temp/scratch - LSI SSD raid0 E:
5) APG sourcefiles and destination - RevoDrive3 F:

Writing the resulting file (often 3+GB) to the sourcefile drive won't be slowed down by reading activities, since the temp-files is on another drive:
Reading temp-files from E:  writing resulting file to F:

Maybe a Revo can replace the LSI raid, that is two Revos side by side. It would be much cheeper, but not as fast.
I'm a bit worried for issues, though.

leif,

benchmark, your array and the revo drive and can get some insight into which will do better

atm, i am getting an average 1GB/s transfer on my 6-8 drive array using samsung 8x830 and 2x6x intel 520's (the later is stripped over two controllers)

I have done that. The LSI raid writes 1 GB/s and read 1.6 GB/s. The 256GB Revodrive can't match this.
See ATTO benchmark below.

Maybe there is one more thing to consider:
for the APG temp/scratch  I guess that iops is more relevant than read/write speed. This disk is peppered with hundreds of small files.
for the APG sourcefiles and destination sequential read/write speed is probably of more importance than iops

If this is the case I will have to swap the LSI and the Revodrive, since it seems like the Revodrive has better iops performance for 4K files threaded.
When there is some spare time I will look more into this.

Henrik,

My mobo is this Asus board http://www.asus.com/Motherboards/Intel_ … rComputer/
It has 7 PCI-E Gen2 x16 IO onboard, no PCI-E gen 3

The LSI has 16i and 4e channels.
The raid0 consists of 8pcs Intel X25-E 32GB SSD. These are "old", but they are SLC and therefore relative fast.
The card is 8x and and take  6Gb/s per port. 8x gen2 means theoretically maxout at 4GB/s. I'm not there (yet).
(The Revodrive a x4 card.)

I will run the PTgui speedtest using APG later and tell you what I see.

Hi Guys,

As I have to process more and more panoramas it also needs to be done faster and faster. Having the sourcefiles on a SATA-SSD is not fast enough anymore during loading and editing, too much waiting. Do I invest 500 euro into ultimate speed (OCZ-RevoDrive-3-X2 RAId-0, 1500 MB/s 200000 IOPS)  or do I go for good speed and more size so I can keep more project on SSD (OCZ-RevoDrive-3 480 GB,1000 MB/s 130000 IOPS).

Or should I use my current revodrive 3 (111 GB 975 MB/s 120000 IOPS ) for the sourcefiles and use the OCZ-RevoDrive-3-X2 RAId-0 for scratch?? having 240 GB scratch file might also help while rendering as now sometimes  I see autopano filling up the 111 GB on temp-files and going to secondary tempdrives. Not a big problem but it is a slowdown..

BTW a big project in my case has 30 GB of sourcefiles and consists of 30 panoramas.

ok hypothesis or not, it sounds logical ;-).

So that would be old revo for sourcefiles ( 975 MB/s is less then 1500 MB/s but much better then sata) and new RevoDrive-3-x2 240 GB for scratch files.....

anyone else with ideas?

Rendering I often do when away from my workstation for long time, so not that important to me. I don't mind a bit of swapping as long as it does not wear down my machine too much or slows things down. It is the speed when I am editing etc. that counts for me

So if I would have only have about 4-500 euro and therefore can only buy one Revodreive-3-x2 240 GB,  that would mean the  old revo for sourcefiles ( 975 MB/s is less then 1500 MB/s but much better then sata) and new RevoDrive-3-x2 240 GB for scratch files AND the pagefile. later i can always buy another revodrive for the pagefile, when money cames in.

This afternoon things looked like this at my machine, things maxed out ;-)

Hi Leif,

My current mobo is limited to 16 GB, so in time it will need to be replaced by one that can hold like 96 MB.
My upgradepath is to buy and use already some parts that can be used very well in that new machine later but also help the current machine. The revodrives are certainly parts like such. After adding one or more Revodrives I will start looking for a new mobo and CPU and start it up with initially something like 32 GB and the revodrives I already have. Then step by step add extra memory once I can afford it.
