Msata SD Chip not being recognized

Just got a new Drobo 5N last week. I also picked up a Patriot Pyro M3 128GB Msata card.

After popping it in and starting up the Drobo, I expected to see in the DroboDashboard the area that says ‘hot data cache’ turned to on. However I have had the drobo running all weekend and it still shows it set to off. I have been doing a lot of reading from the drives, but still have yet to see the hot cache turned to the on state.

Does it only show as enabled when it is actually performing caching operations, or should I be seeing the hot data cache enabled immediately upon restarting with the chip in. If that is the case…need to figure out why it is not showing up as enabled, if it is the Drobo or the chip…

Any info would be helpful.



It looks like you have a SandForce-based mSATA card…


SandForce SF-2281 Powered
SATA III 6 Gb/s Compatible
TRIM support (O/S dependent)


Taken from the Specification page of this link >

Drobo does not support SandForce-based cards, so this is likely the issue.


NOTE: Currently we do not recommend the SandForce based cards, for more detailed information refer to this knowledge base article. - See more at:


Thats a pretty good reason :slight_smile:

Thanks for the info! Looks like I’m heading to Fry’s tomorrow to see if I can swap it out…

Thanks for the information!
