My editing workstation needs work and I need help.
I have a decent editing system that's about 2-1/2 years old. (Asus P658D, Core I7/920 OC'd to 3.8Ghz, and 12 GB fast memory.) I use it for editing stills and video, and a few other things. Until last week, all was well. Then one of the two disks in my Raid 0 data drive failed partially. With about 10 hours work, I was able to copy most of my media over to another drive.
Rather than spend the money to create a robust disk subsystem with multiple drives and a nice raid card, I opted go cheap and build my data subsystem using two drives in Raid 0 and use a backup utility to copy the media to a separate backup drive. This worked reasonably well for a while, but some time in the past the backup utility failed. So my media was living "on the edge". And I lost some of it when one drive partially failed.
This has to be remedied. The options are:
1. Replace the bad drive and configure as before.
2. Update the disk subsystem for better performance and safety.
3. Upgrade the entire workstation with new mobo,cpu, disks, etc.
Option 1 is too limiting and unsafe, so it's option 2 or 3.
For option 2, my current disks available are:
- MOBO disk controllers (2) - Marvel used for Raid.
- WD Velociraptor 300 GB (x2) - Currently one each for system disk and media cache/page file disk.
- WD Black 2TB (x1) - Was part of Raid 0. Now just sitting there.
- WD Blue 2TB (x1) - Backup disk.
- Old WD 500GB (x1) - Currently in removable bay for archiving.
New disk sub-system configuration (one alternative):
- Areca 1882ix raid controller (maybe PCIe 3.0) for current and future needs.
- 256GB SSD - System and Apps. (New)
- WD Velociraptors (x2) in Raid 0 config for media cache and page file. (Current)
- WD Black 1TB (x6) in Raid 5 config for media, projects, and other data. (New)
I'm not sure about backup and arhiving. Maybe repurpose WD Blue 2TB and old 500GB disk in the removable media bay?
Does this look like a reasonable disk config? Better options in general? Better options for backup and archiving? Bigger disks for Raid 5 (for future expandability)?
Option 3 - Rebuilding the entire system is certainly an option, but I think it would be a lot more work. I know that I'll need to do that in the future, but I'm wondering if it's good enough for now. This is a tough question.
I'd appreciate any help.
