My application is to use TMS320C6678 to access SSD and I choose Marvell 88SE9230 as SATA Host Controller.
The TMS320C6678 can access 88SE9230 through 2 lanes PCIE at 5.0Gbps.
Here is my question:
1.My write and read speed requirement is above 450MBps,is it possible with one SSD?(The SSD can meet that requirement and I use Linux)
2.If the requirement can not be met due to the filesystem,how about use Raid?(like Raid 0,using 2 SSD)
3.As 88SE9230 can support hardware Raid,should I write my own Raid driver or just access the Raid through ahci platform?
