Such is life of a Drobo I guess. Heh. Kind of surprised this whole SSD thing not only passed the notoriously rigorous Drobo Q&A but also made its way to the recommended list of SSDs. Funny how things work out.

I still believe it is an issue with the m4.

The Intel 525 I installed in February is still showing 100%.

I write about 125GB week and read around 250GB week.

That's comforting. Looking forward to your results.

I get the impression that DashBoard didn't accurately indicate the health status of (at least) the M4 SSD until release 2.5.2.
Drobo mentions nothing about this in their release notes. They are either unaware of any problem, or they are not revealing all they know.

I wouldn't completely trust DashBoard on this.

This is undoubtedly good advice.

Mine's still at 100% after four months and at least a dozen terabytes written. All I can say is YMMV.

I too am under the impression that the health meter essentially wasn't active until this last release. What happens when the SSD runs out of "health," well, I guess we'll find out sooner than we otherwise should.

RE: mSATA Life Failure w/ Dashboard 2.5.2 and Firmware 3.0.7
hi does anyone know more about the "logic" behind the data aware tiering processes?

what i'd like to learn more about is the "IF this do this, ELSE this" statements behind it. im guessing business sense would mean that the process is patented (which is fair play for a business to do), but im also hoping that if the patent process is also public knowledge (like the original drobo patent was on the web before) does anyone know where to find more information on this?

i think ive posted someting similar in the past but it would be really helpful to know more about the data aware tiering process (and scrubbing) on what it does/doesnt do, when it does it, and why it does it because we might be able to restructure our side of the drobo content accordingly, to be more efficient in tandem?

(btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused)
& a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)
  • btw i did a sustained (write) operation for about 6 hours, and got 13.2MB / sec ...objection? "sustained" :)
    (16.7MB/s on a v2 & 47-96MB/s drobo-s)

I believe the patent gets published after approval. It's currently pending, so we'll have to wait.
