External storage for early 08 mac pro for video storage and editing
Early 08 Mac Pro mod 3.1, 2x Intel 2.8 Quad Core Processors. Bus speed 1.6 Ghz. 10 GB DDR2 FB-Dimm 800 MHz. USB2, Firewire 400, 800. ATI Radeon HD 2600 PCIe 256 mbVRAM. Currently running OS 10.6.8.
I use machine for photo and video storage and editing. I tried using 2x 3TB and 2x1TB HDD internally ( 8 TB total). All are Seagate Barracuda SATA 7200. Experienced constant spinning wheel and lockup requiring manual shutdown. I had upgraded to Lion and to Maverick. Did not help so I did a clean install of primary with Snow Leopard and did not install past 10.6.8. Works now if I don’t exceed 3.5 TB internally. I also discovered that my Disk Permissions experienced voluminous corruption that could not be repaired if I installed Java for Mac OS 10.6 Update 17 as suggested each time I check for software updates.
I need to be able to have a total of about six TBs available in my system for storage and editing of video via Imovie. I don’t know the maximum of HDD storage that can be used in the four internal bays without causing lockup and corruption. If 3.5 TB is about the max, then I would like to have some ability to have external storage via firewire 800 if that would facility fast enough transfer for either video edition and or playback. I don’t know if thunderbolt can be installed via PCI card. I could add a SATA PCI card. However, I assume that would cause the same problem as experienced with 8 TBs installed internally in the four bays.
I would appreciate any suggestions.
