Drobo 5d and FCPX anyone?

[Gary Adcock]

SInce the Drobo unit is not yet shipping and the Promise Pegasus has a proven track record why is it an issue?

The Pegasus does allow you to swap out drives- just purchase a couple of extra trays.

You cannot expect just any unit to achieve these kind of read write speeds using just anybodies plain old drives that you have lying around however

My Pegasus as 3T Sata3 disks at 15K RPM- this sample data rate was achieved using a current gen MBP_Retina with 16G ram and SSD drives

Wow, pretty impressive. I think I’ll just go with Promise then. Too bad you can’t buy the enclosure without drives. It’s quite an expense to remove the ones that come with it and swap in your own. . .

you are kidding right?

the apple store lists the 12 TB unit for $2499.00 (US) ( that is $208 perTB)

just 5 short years ago that 12T would have cost about $ 15,0000 Us

to attain those read write speeds over fiber will cost a user about 3X -5X as much (depending on fiber card)

Fair enough. Fair enough. Still, why don’t they just sell an empty unit? Doesn’t make sense to me. . .

That is a nice, flat graph with no nasty slow spikes.

Thank you for noticing, not many do.

I kept it with in the cache system on the drives, performance is always about having the system tuned regardless of the content you are working with.

Okay, now I’m really interested.

Forgive me. I’m just an editor who somehow ended up as the post supervisor and am now responsible for planning equipment purchases and workflow for a growing production company. . . moving from a one man band environment to more of a production house. So I don’t have a tonne of experience here, but I’m learning fast.

I’ve heard about this idea of “tuning” and how important it is, but I never understood exactly what this meant. Can you explain? How do you “tune” a storage array?

Now, this is a little off topic, but we almost went to shared storage this year, but XSAN was too expensive and I wasn’t sure a gig-e NAS system would meet our needs, so we are continuing with local storage for now. If you have any tips or resources for better understanding the options (especially for use with FCPX) that would be much appreciated as well!

Best,

Oren

Oren,

there are any number of ways that your setup can slow down data transfers or editing in general.

Block Size – adjusting the media block size when formatting a drive can effect speed most drives by default segment volumes in fairly small block sizes. FAT32 uses a blocks as small as 4k, and that can be problematic when you have to read and write files that are Gigabytes in size, but can waste space when using smaller files.

raid level this is a big one, yes RAID 0 is fast and RAID 1 is slow, finding a place where redundancy is offset by speed is always a difficult process. I work with my portable systems in RAID 6 where I can loose 2 drives without loss of data ( but a much longer rebuild time)

Another thing that can be done is limit other software from infringing on resources, Itunes and safari both rob low powered systems of needed resources.

the list is long.

Fascinating! On my older MacPro, I have often noticed editing performance is slowed down significantly if Safari is running.

So, I know how to set-up RAID levels, but how about block size and protection from infringing apps? Is this something I can do in disk utility or preferences, or do I need specialized software (or a specialized person!!!) to help me with this?

Is there somewhere I can go to learn more?

Cheers,

Oren

Now my company is using Drobo.It is solid, Synology NAS too, just kind of depends what you’re after. If it were me though, I’d do a multi-drive NAS with another directly attached HDD over USB. I use a 2-bay Synology for time machine backups and storing media files, with a WD external hard drive that runs backups of the Synology. I get the coupon code from this website before buying this products in drobo.com – https://share-coupon.com/drobo-promotional-code
I got $150 off through the web site.
