Drobo Pro two drive failure demo

I was looking at the blue lights lol

"Movie never stopped running" It did now!

How would you rate this compared to a HP MediaSmart server?

[StorageMojo]

Way easier to use. Drobo is a storage device and needs a media server like Western Digital's in front of it. HPMS is, IIRC, a media server itself, but comes with more mgmt overhead.

Drobo is a good idea but it is very unstable i had a drobo but it ended up in the middle of the road, worst £400 i spent suffered complete data corruption TWICE! now i've got a "readynas pro" with X-RAID in dual redundancy mode for £800 and it keeps on running and running and running not had one problem with it. if you look around on the net alot of people have had alot of problems with Drobo.

I have the standard 4 drive drobo and I love it.

I want to buy a drobo pro, but at $1400.00 without drives it's going to be a while before I can budget it.. I may just buy another single drobo to tie me over till I can afford to spring for the pro.

[Finchwizard]

Shame there's no Networking available in it, such as SMB etc.

Otherwise would of been a pretty decent machine.

They're still expensive all these external NAS type devices.

Vital - OK, now pull 2 drives - leaving only one running. Let me knnow how that works for you.

He should be fine, seeing as to match the dual drive config he would be running raid 6, which in fact does offer protection for two drive failures.

If he had raid 5 then he could reconfig the array to use a disk less, and then pull another drive if he was running raid 5 (exactly what the drobo is doing, except it just does that for you) and it'll keep running fine.

[vitalscuba]

Big deal. I'm notified when 1 drive fails, and I can swap in a new drive. Not sure how often 2 drives fail at the same time. Doesn't justify spending astronomical amounts more money for a technology that doesn't seem to really fill a need.

Most modern motherboards seem to come with RAID built in. Why would I spend another $430 on a drobo PLUS cost of drives?

You can pick up a nice raid system with share and drives for $250, drobo share is minimum $630 without drives. No thank you.

[vitalscuba]

Also, the site isn't very clear - but it appears the only Drobo that supports 2 drive failure is the $1500 model. Plus the cost of drives.

@vitalscuba You don't know what you're talking about, clearly. Have you ever heard of URE? Unrecoverable Read Error. When that one drive fails, you go to rebuild the array and you get one of those. That's game over. With large SATA drives, you need double redundancy. The error rate is about 1 in 1x10^14 bits, it's one order of magnitude higher with SCSI drives.

[HoneycombAgent]

@Nater245689

Are you talking about RAID-1 or RAID-0?

[Nater245689]

@HoneycombAgent I'm talking about any non-raided or RAIDed hard drive. In any given number of bits, you will have an unrecoverable read error. It's 1 in 1x10^14 bits (about 12.5TB) in SATA drives, about 1 in 1x10^15 bits in SCSI drives. This is a serious problem for RAID 5 as the array rebuild process will not be able to continue and you'll have data loss.

[vitalscuba]

Big deal, the Drobo is expensive. I can pull a drive on my raid array and not see a flicker on a video.... costs 1/3 the price.

[mejdam]

expensive but worth it. i have a drobo with 3 2tb and 1 1tb drive. LOVE IT

[bobwatters]

how much do they cost

[lappodude]

yeah.. but you can't put in a new disk and the drobo will self "heal" that new disk.. you don't need same size disk in those slots:p
