I just installed a Samsung Evo 850 in mine and it appears to work fine. The only concern is that you don’t use a Sandforce chipset-based SSD. Since Samsung designs their own SSD’s it was a fairly safe choice.
You can install it at any time; doesn’t really matter. To my knowledge it’s only used as a read cache, so it won’t get clobbered as you add data to the Drobo (and it won’t harm anything if it fails).
My Drobo 5D went into read-only mode when I inserted a 250gb Samsung Evo 850 mSATA. Went back to r/w when I removed it. I figured the 850 was incompatible until I read in this thread that @diamondsw got it to work. Firmware and Drobo Dashboard are latest versions. Running Mac OS Yosemite. Any ideas?

Hey Paul, thanks for the response. I actually was able to get the drive mounted r/w by hooking it up to a different machine and then switching back. Likely just needed to be power cycled. As for 128 vs 250, I have no idea. It was $30 more for 250, so I figured I might as well. Hopefully it’s not a performance detriment.
ok joel its good that its back to r/w again,
i dont think youll get a performance detriment, (usually people just tend to say that there isnt much justification in getting a larger one for a speed boost)
I’m using a 120GB Samsung EVO 850. The mSata was fine at first and then died after 3 weeks of usage in the 5N. I sent it back thinking it was a faulty unit, but the replacement card died 6 weeks afterward… I’m waiting for the replacement unit once again.
If this one fails I’ll probably try an Intel 525 as listed on the compatibility page.
A quick update.
The replacement of the second unit is a little more cumbersome than expected, so in the meantime I found a super deal to get a 120GB mSata Intel 525 and I bought it instead.
I’ll get the EVO 850 replacement unit and I’ll sell it online sealed to get my money back.
I don’t know if it is the EVO 850 that is incompatible with the 5N or my specific setup that is to heavy for the mSata drive. I’m a pretty heavy user of my 5N. I’ve got 12TB on it, with multi-millions small files for work that I need to access constantly and I also use it as my main storage place for music files, movies for Plex, etc… So it is under a daily, constant and heavy load of activity.
I had a 128 GB SanDisk X110 in mine. It was reported as failed. I took it out. It works fine in a NUC. I won’t bother replacing it in the 5N. I store mostly big files and it made no discernible difference when it was there. YMMV.
