How long does it take to empty a 64gb red ssd card?

[Brian Iannone]

Do you mean something like those Epson P-6000s? Except, instead of transferring to CF cards, going directly to large 2.5" SSDs?

That would be convenient.

Won't really work that way. SxS are ExpressCard and limited by the ExpressCard interface. Which happens to be PCIe, same as Thunderbolt, but we're capped at the speed of the EC interface. Essentially, it's PCIe X1 (single lane). And SxS is yet another key point on which to question Sonnet's thinking here... The Sonnet reader should work as a standard ExpressCard interface, meaning they will support SxS media. So once again, WTF is Sonnet thinking??? Why not make a dual-slot model with pass-thru and it would be one badass SxS reader. Support EC2.0 and it could be a dual SxS Pro reader that could unload two SxS Pro cards simultaneously with bandwidth to spare. ...Nice going Sonnet, you missed the boat by at least 10 miles.

Kinda makes me think about canceling my order, but no one else has announced a similar (let alone, better) product.

Got pretty excited when I bought the thing at Melrose Mac and the packaging it comes in has "Supports SxS Cards" printed on it...false advertising, apparently.

Perhaps Sonnet realizes if it was a $150 SxS card reader, it would totally undercut their own $800 Qio card readers...

I'm doing offloads on a shoot today. DIT cart has an '09 Mac Pro and I grabbed some times for you. Using a 128GB RED SSD that has 82.2GB of data on it. Mac Pro has 4 x 2TB Hitachi UltraStars in a RAID-0 as well as G-Tech G-Speed ES connected to eSATA via an ATTO H680. Dual RED Station SSD readers on the ATTO card as well.

82.2GB offload to internal RAID - 5 minutes, 50 seconds - approximately 240MB/s. (via iPhone stop watch)
82.2GB offload to G-Tech RAID - 6 minutes 22 seconds - approximately 220MB/s.

Tried a couple via FW800 for comparison...
82.2GB offload to internal RAID - 18 minutes, 58 seconds - approximately 74MB/s.

82.2GB read from internal RAID out to Seagate 1.5TB 7200rpm 32MB cache HDD in Rosewill eSATA+FW800 enclosure, connected to front FW800 port - 20 minutes, 34 seconds - approximately 69MB/s.

These were all straight drag and drop times in finder.

Wow! Those are good times. Consider me a True Believer! I have to admit, I was surprised to find out not all FW800 controllers are created equal. That's the last time I buy anything but a G-Tech external. Though that Rosewill enclosure looks good! Is that just a regular one you might find on Newegg?

Thanks Jeff -- and Brian -- for setting me straight on this. If I ever see you at a Red event, I owe you a beer

Hi Brian,

Where did you get that from, please ?
As far as I know, LaCie is a company with a very good reputation and high prices.

I've had two mirrored lacie raids, both have "lost" my data.. without even needing a drive failure or any kind of human intervention..

think lacie, think crap .. your mileage may vary..

So to resurect this tread, it seems between 2012 and 2013 the single limiting device in a laptop type data transfer solution is the (usually) single drive parked on the end of the system. The only think i can think of to improve matters is to use twin SSD card readers assuming that is if you want to transfer 2 in parallel to two target drives. Possible I might add an Thunderbolt to eSATA hub to the system to increase the buss speed but Im not convinced that will help.

Any one any insight on improving data transfer rates ?

I had issue recently with 3 lacie raids not mounting due to journal errors. Disk Warrior fixed the issue in a couple of minutes.

I seem to recall that REDmags/MagReader are limited to 220mb/s or so. That basically means USB3 maxes them out. On the HDD side you'd need at least a two drive RAID0, but any more than that will not help your offload speed. Otherwise, even entry level SSDs are now pushing more than 200mb/s these days (the problem is above 256gig they tend to get far less cost-effective.)

That'd be ~5minute offload for 64gig (sans integrity checking), which is about 25-35mins of footy depending on compression ratio... Not bad.

Does anyone know off-hand if (and by how much) slower using bus-powered REDmag reader and portable drives would be? The laptop would (ideally) be plugged in, I'm just talking about the drives... Like having a very small/portable footprint for no mission critical jobs.
