Gigabyte bios updating software
250MB/sec is still faster than a hard drive, but you're capping the performance at less than half of what the SSD could do.
Some commenters below have reported getting an error when trying to install Windows 8 at this point.
The non-K OC is really easy and can be done within few minutes.
Few days ago I published a short article about overclocking non-K CPUs.
I don't see any mention of an SSD issue in the BIOS update notes over the years though.
To be on the safe side, especially if you are having issues, its recommended installing all the drivers. the Gigabyte Brix was named after Colin Brix, who is a marketing director at Gigabyte's Motherboard Business Unit.
I think the problem here is PCIe 1.1 and that limitation has already been noted (aginst my suggestion.) I was under the impression that there were still PCIe x4 controllers.
There are, but they're full on RAID cards and priced to the point where you'd be better off replacing the CPU/Motherboard/RAM than fix it that way.
You can download the BIOS update tool from the Gigabyte website.
Here is the BIOS download page for the Gigabyte Brix GB-BXBT-2807 model:
