I have two servers that have failed hard drives. They are each about 3 years old.
I am considering replacing the drives, and their controllers by SATA controllers and SSDs. However, I have been told by a number of local experts that often times the SSDs are not properly recognised, and also that at least some require special drivers.
I suspect your local experts are talking about PCIx-based SSD when they talk about special drivers. They are the top of line in SSD performance, but are in general are not supported under linux. Exceptions exist (I think).
For SSDs that use SATA as their command/data interface, special drivers should not be needed.
As to geometry (partition alignment), it should be default now to align on 1MB boundaries. If you ensure that is where your partitions land, you should be fine.
