We would like suggestions on upgrading two identical PCs. (Hardware is not our strength, nor is the hardware lingo, so please take these descriptions and word choices with a grain of salt. We will have a local hardware expert do the rebuild and set up.) We edit HD (and potentially higher) projects that typically exceed two hours. We also use Lightroom for processing images with file sizes typically at 40 – 50 meg. We just added an 80T NAS (with other NAS backups) that has 10G LAN speed, but we currently only have a 10/100/1000. We process the images from the NAS. We typically store the video files on the NAS, but copy them to a local drive while editing. For short video projects, we’ve been able to edit leaving the files on the NAS. We are adding an Nvidia Quadro P5000 to drive new 10 bit monitors and for video processing.
The mobo is a Gigabyte GA-X58A-UD5, with a Core i7 950 @3.07GHz, and 12 GB RAM. The mobo can support only 24 GB RAM, has space for 6 SATA 3Gb/s Raid 0, 1, 5 and 10, and for 2 SATA 6 Gb/s Raid 0 and 1. It is limited to a 10/100/1000 LAN. Each PC has a 1T Samsung 850 Evo in a SATA 3 Gb/s space with the OS and applications. We do not see using M.2 x4 Gen-3 SSDs until there’s a significant price drop. Our initial plan was to add two Samsung 850 Evo 1T, which are SATA 6 Gb/s.
Our first question is could we process the videos from the NAS if we ran a 10 G LAN, and get real-time processing from Premiere Pro, even with effects applied. This would eliminate the time taken to copy the files locally, and the complexity (and discipline) required to clean out the local SSD at the end of each project (who knows when they really end). And would a 10 G LAN reduce the time Lightroom takes to snap in the images?
Running a 10G network would require a new mobo, which leads to the question of what mobo the forum would suggest if there's benefit to upgrading it.
Our second question is what should our SSD set up look like. Should we group multiple SSDs into a read RAID and a write RAID if we’re going to edit from local SSDs? How many SSDs? Assuming we use such RAIDs for files that are also kept on the NAS, the risk of a failure in RAID 0 would seem to be acceptable for the improved speed, as long as our projects were kept outside of those RAIDs or backed up frequently. Since the Gigabyte mobo has only two 6 Gb/s spots, should we move to a new mobo just to get more 6 Gb/s spots? Or would multiple SSDs in RAID 0 at 3 Gb/s keep Premiere Pro's performance high? We would probably include at least one HHD for “typical” files.
Our third question is the role of RAM in our processing. Should we at least put 24 GB RAM onto the current mobo? Or is RAM important enough itself to justify a new mobo that will take more than 24 GB RAM?
Underlying our thought process is that we do not need to get a new processor – regardless what we do with SSD, RAM and a mobo, we would not get enough performance increase to justify a new processor. But maybe we’re trying to build a mansion around a mobile home and we should get a new processor too.
