RAID 5 config – 6Gb/s query
Hello,
Currently in my MacPro 3,1 I have a G-Tech 4-Port, PCIe x4 RAID Controller. I plan on using a G-Speed Es array with it and configuring to RAID 5.
I used to have installed a Sonnet Tempo SATA Pro 6Gb 4-Port card…but apparently it didn’t have a RAID controller, which is why I switched to the currently installed G-Tech RAID controller as mentioned above.
The Tempo boasts 6Gb/s, while the G-Tech can only handle 3Gb/s.
So here are my two questions:
1. Is there a 4-port eSATA card that is BOTH a RAID controller AND can handle 6Gb/s? Any suggestions? I was looking at either the HighPoint RocketRAID 644 4-Port External SATA 6Gb/s PCI-E 2.0 x4 RAID HBA or the HighPoint RocketRAID 640 4-Port SATA 6Gb/s PCI-E 2.0 x4 RAID HBA
I am not familiar with either of these cards nor the company in general. Is this what I’m looking for? Part of my skepticism is because they both list for under $100 while both the Temp and G-Tech are about $300.
2. If I were to find an applicable card that can be both RAID configurable and 6Gb/s, but I’m transferring data to a G-Speed eS array which supposedly handles 3Gb/s, then the 3Gb/s speed is the fastest it’s going to get, correct? It seems obvious and it probably is, I’m just trying to wrap my head around this concept.
I just don’t know why there are 6Gb/s cards and only 3Gb/s RAID systems. Am I missing something? Please educate me and pardon my ignorance.
Thanks!
