Meet CHEETARA (Dreamt This Forever. 2013 will be great (portable) year eva')

With MBP (r) added Just two seagate backup Plus (New version, 7200 rpm) via Seagate thunderbolt adopter (Stripped) and I get this... WOWOWOWOW...

I will return Drobo mini (tomorrow) and get two more Backup plus and two more thunderbolt adopter total 12TB (stripped) = CHEETARA on STEROID in my backpack... D.I.T TECH SLAP (lol)

i have the seagte thunderbolt adapter as well and it rocks.....but it only has one tb port...how are you planing on connecting all these drives?
there are a couple of small raided boxes coming out but they either need AC power (LaCie) or run at lower speed when bus powered (promise)....
as far as your idea to make a striped array with all these adapters and HDs.....you are aware that if only ONE drive fails, ALL you data is gone....right? especially on location this is really risky.....i would probably go with ssd drives...yes, more expensive but you get R/W faster then that from a single drive and there are no moving parts, so the risk is much lower...and you obviously don't have to stripe them to get those speeds which reduces the risk immensely......
lacie now makes their rugged portable line with ssd with thunderbolt and usb3....very fast, very reliable....
and realistically a year from today we will see 1-2TB ssds in the same price range as HDs are today....

since kwan is talking about a portable solution, i was assuming he meant the portable (bus powered) TB solution....which only comes with one port....all the portables do, otherwise it draws too much power....promise has a portable mini raid but speeds are much slower when bus powered...

Sorry Paul, There is no way you can have 3/4TB 2.5 7200rpm HD any time soon. Todd is correct.

I meant portable solution comparing large and heavy raid bay system like;
Maxx Digital's ThunderRAID 8 Bay (16TB) $3,995.00
ARECA
Pegasus R4 and R6
Sonnet Fusion

Without any doubt, Above systems are the best but prices are crazy high plus they won't allow you to swap drives (unless they offering now - lol)

I get have 12TB Thunderbolt raid for under $1300

And Yes, I use SSD with this system without any problem, That is why I'm returning Drobo Mini (lol).
I wish if seagate has 2 TB port in mini adapter, Those Little Things That can Make Life Much Easier - lol
 
Hi Kwan, I'm going to follow your lead on this-unsecured drives in the rocketstor are too risky! The seagate back up drives also have uzb3 and fw800 so are. Fairly compatible across the board! Thanks for the recommendation!
 
Hi guys

Just for info; we've had some serious data loss issues with external hard drive caddy's (Voyager Q's) connected via FW800.

If our Mac's crash or lock up and we have to force quit, drives have not been recognised when we re-boot and we've had to re-initialise these.

For field use, we always make 3 copies before we reformat our Red SSD's - G-Raid mini's in raid 1 config have worked well for us.

Another thing I'd suggest is when buying and setting up Raid systems, is to seriously test them before you start using them for critical work - yank out a drive, pull power etc and see how they cope.

We have a 8 drive Raid 6 unit which should survive a 2 drive loss - ours didn't and we lost a serious amount of data. We had most of this backed up elsewhere and only lost some low level footage that we can live without BUT it scared me big time!!!!

Best wishes

Scott
 
There ust be some serious quality issues with these Seagate TB to SATA adapters. We've picked up 4 for our lab and 3 of this are lucky to hit 95MB/sec write speed while the 4th screams (280MB/s write, 302MB/sec read) using the same SSD drives. We've contacted our Seagate OEM team about the discrepancy.

If you do go this route, make sure that you can return and get a replacement if the speed isn't correct.
 
i dont like open trays for disks if they are used intensive as for copying red files: the cooling is far from optimal, which is not good.
if we dont go the usb3 route with a fast 4 port usb3 hub, 2 usb3 drives and the red reader connected to it, we recommend the lacie 2big thunderbolt drive, and buy extra spare trays. you can also buy the new lacie 5big thunderbolt for extra trays/drives and use the 5big during postproduction, the trays are compatible with the 2big thunderbolt. The drives are formatted as jbod in the 2big and when sending to postproduction, they can put 5 masters disks in one box. as both the 2big and 5big have 2 thunderbolt ports, you can put a lot of disks on a machine = 6x 5big/thunderbolt port. We mostly work with the 3TB trays as they have the best price-capacity ratio and they are fast : between 100-150MB/s.
We dont recommend the use of a raid1 or raid0 configuration - you could switch to raid0 if you work with arriraw files, as they need approx 175MB/s and use two 2big boxes for the 2 copies, but for RED files, single drive is plenty fast enough.
Raid1 = mirror seems also nice, but when doing a checksum verify, you cannot know which drive was used during the reading of the verify, so it could be corrupt without you knowing.
The disks in the 2big/5big are in a tray, but you can unscrew them - you loose the 3 year warranty :-( and they can work this way in a macpro-trays or other disk-housings-trays. They have the same formatting as if you would format them in a macpro.
Attention: they are NOT compatible with the newer 2big usb3-version. the old usb3 version was fine, the new one uses a special raid0-1 controller which makes the disks outside this usb3 box incompatible with other housings. Stay with the thunderbolt 2big/5big.
