I'm using a SATA SSD drive connected to the TE0803 PS. I built linux based on the StarterKit image. I needed some changes in the rootfs like adding hdparm and mkfs.ext4.
The thing works except for the read/write speed that is far below the stated in the SSD datasheet (560/ 440 MB/s). I'm not even getting half of that which I think it's an indication that something is missing somewhere. I'm not asking for the very top, I just need an average of 250 MB/s over 5 minutes that I think it should be perfectly possible (?)
Hi,
SATA is realised over GTR, performace depends on PS setup and Xilinx drivers. We did not configure for fast speed on our reference design.
