Hi tntxhy,

The spinning hard drives in my Pegasus R4 show 6Gbs. These are the drives it shipped with.

If the Pegasus firmware is not up to date, maybe updating would help.

Hi R P,

Thanks for your help.

My Pegasus firmware version is 5.04.0000.61.


Is it up to date?

Hi tntxhy,

Yes, your firmware is up to date. The Pegasus 1 is long EOL, there's nothing more that can be done.

I am not aware of any bugs or issues regarding drive connect speeds with the Pegasus 1, but the drives you are using are very recent and the Pegasus 1 was never tested with drives like these. I have 2 old SSDs (200GB and 300GB I think) that I have tested with the Pegasus 1 and they connect at 6Gb/s.
