  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Why I am Loving SSD

Eric.

Yeah. It's just my general belief that shooting ratios have gone through the roof. As a person who edited for many years I can see it as milking the day sometimes.

Depending on the type of film I mostly like smaller drives as a way of rolling them over more often. That's a safer approach to data based acquisition. I guess I mean it more that way.

I love the CF card too. I was one of those people who hoped that CF would replace tape.

...Area i work is usually on a boat, island or camped out....so i've been faced with most of these questions. Genset is best way to handle them. Then if camped out on the coast in my van, i run an inverter tied into two deep cycle batteries that are charged either by my van's alternator & solar panels. So go out shooting, then back to van to run power and offload...

Plan to do some way out there shoots...and wondering about the
usefullness/efficiency of solar. Do you have any info. links to solar panels.

I understand that, and in my own general experience, when I'm managing data, I can always discreetly persuade camera department to offload at reasonable intervals at a convenient time of course. Actually most camera teams I've dealt with so far (albeit generally short term productions with single cameras) actually offer to offload after shooting around 32GB without me asking.

If it really came down to camera dept/director refusing to do so, I'd only need to have a word with the producer that a) it'll cost the production overtime to offload an unreasonable amount at the end of the day and that b) they won't know they have the show in the can until I do!

depends much on your power requirements and how long you'll be in the field. 9.9 x of 10, it's much more convenient and less equipment to bring a genset and fuel. For solar, you need to first asses your power requirements and then work backwards and design a system based on those power requirements. Then that usually means 12volt battery system, 110 inverter, solar panels......gets into a lot of gear. Biggest of that are 12 volt deep cycle or 6volt deep cycle batteries. In fact i just bought new 6volt batts for a base camp i have....44 batts in all which is over 2000lbs in batteries. if i ever have the option, i go gas genset.

but glad to assist if you have detailed questions.
 
You know, if you've spent a long day coding and then glance at reduser, and see this thread, I'm sure it actually read: "Why I am Loving LSD"

I'd actually like to see them with some higher capacities. I like 256gb. If SSD is like HDD...then as you near say 65% or 70% capacity there is quite a noticable throughput slowdown with the disk. I'd found that with the RED drives if for any reason i shot with one that was near full. Reasons for shooting were typically a short one or two day shoot in a remote location with no power to offload data.
Very rare indeed, but at 128gb....what can you actually hold or shoot before you get disk slow-down? 80 or 90gb? or does this no longer apply to SSD as with HDD?

It does not apply. Spinning drives have varying cylinder size, as they are like vinyl Lps - the outside has longer grooves than the inside, and thus random access is slower. SSDs have uniform cell distribution - each data point is as fast as any other.
 
I shoot live concerts, up to 10 Reds with single 2 hour takes. Larger capacities are a must!

I have shot 320GB to within 4% several times and never missed a frame.

I'm going to have to think hard about how to get through the next year as capacities build up with SSD. :blink:

Existing Red Drives are an option but I imagine we will start seeing widespread issues as time goes on and they get older. :crazy:

Can I assume RedLSDcolor is about to be released?
 
Confusing. Red.com has recently been updated.

And now it says:

RED continues in that vein by offering 2 robust, flash-based recording solutions for EPIC, which will be available when EPIC ships; Compact Flash (CF) card, by virtue of it being an industry standard, and SSD, for its durability and long recording time.

I thought that Jim had said that CF was not supported for the Epic.
 
While I am neither an expert on the subject, nor am I aware of what RED has done as far as their new 1.8" SSD drives. In general:

SLC SSD drives: offer less capacity but increased reliability and an approximate 10x life compared to an MLC-based architecture; require less time to read and write the data to each cell, and therefore afford better sustained performance.

Conversely, MLC: has a 2x-4x increased capacity; has a 10x less lifespan and are more prone to data integrity problems, especially when approaching the end of useful life; require more percent of the drive's physical capacity due to over-provisioning (user unaddressable space) per GB. Often times provisioning as much as 10-15% of the total drive capacity.

However, at a certain point the throughput of many of the SSD SATA2 drives are not the only limiting factor. Mind the fact that SATA drives are still governed by the limitations of the southbridge chipset which controls, among other things, the SATA channels. For example, the Intel ICH10 chipset the limit is 3.0 Gbps per channel.

Wow, RED SSD are really SLC drives ? That explains the pricing. Are they SATA ver.3 (6 gbps) ?

I think that complete technical specs should be displayed for every item on the RED store . A picture & a price are not enough when you buy that expensive stuff.

I don't know if the new RED 1.8s are using SLC or not. Perhaps they have released the technical specs and I have not seen it. However, I would personally make that assumption, given the obvious benefits of the more robust performance, data integrity, and life-cycle benefits compared to MLC.

Frankly, I am glad that they have decided to go with SSD. There are other numerous benefits, some of which have already been pointed out, like the physical durability for example. Also, by and large they consume much less power compared to spinning drives and have no moving parts to wear-out. And while CF cards are flash-based, they simply cannot sustain the sequential writes needed to handle things like HDRx, 5k RAW, and high framerates, and are therefore obsolete for such purposes.

It would be nice to have tech specs for the drives, and perhaps the data architecture that they have chosen, even if for a cursory understanding by the electronic geeks among us.
