I want to build a hardware RAID1 setup with two HDDs (SATA3, 7200, 64MB cache) and I'm looking at two, almost the same, Adaptec cards (6405E vs 6805E)
The 6405E is PCI-E 2.0 x1 while the 6805E is PCI-E 2.0 x4. Both are 128MB cache.
If I take the 6405E, will the PCI x1 bandwidth bottleneck be really visible? This won't be a system drive, just data.
NB: Other Adaptec models might better suit my needs/budget (eg: 6405), but I can't find them online.
PS: Yes I know, the battery module is not included (6405E) / not possible (6805E)
