Title: SSD Cage for Chronos 1.4/2.1-HD - 3D-printable
Post by: tesla500 on March 25, 2020, 03:13:49 PM
This is an SSD holder for the Chronos 1.4 and 2.1-HD. This accessory is invaluable when shooting DNG on the go; save speed is vastly improved compared to an SD card. The camera can write about 60MB/s to a SATA SSD instead of ~12MB/s to most SD cards. DNG saves at about 12FPS on the 2.1-HD and about 18FPS on the 1.4, at full resolution.

We plan to offer this for sale in our store eventually, but you can 3D print one right now! The attached models have been updated from the pictures shown, the SD card opening was widened so you can easily grab an SD card with your fingers instead of needing pliers to remove it.

We're in the process of ordering custom versions of the eSATAp cables that have a short cable length to avoid the need to coil up the extra cable.

3D Printer to print the SSD cage (see attached files)

3D Print Instructions
This file has been tested on the Makerbot Replicator 2X
Recommended settings:
Print with raft, raft expansion 12mm
Print with supports
Orient the part with the drive opening pointing straight up

We've been using these at Krontech for the last few months and these mounts are incredibly useful, let us know how they work for you! One modification we were thinking about is centering the SSD above the camera. Currently, it overhangs the screen and makes it harder to see if you're looking from an upward angle. Thoughts?

You can use the m2 SSD on the top of the camera and they may not cover the screen

Not yet, I'm waiting for my camera.

through this adapter, you can use m2 SSD. And with the help of a 3D printer you can make a housing

What is the maximum speed of the SATA connector? And in General, all the connectors through which you can write files, how can you find out their maximum recording speed? USB, SDcard.

Or is it the maximum write speed of 12 MB / sec, regardless of the speed that the SD card can write

Not Quite sure, but i think its more of an internal Limit bevore you will hit the Limits of the SD-Cards or SSDs (There are sure some Pretty slow and old SD-Cards or drives that will limit Write Speed, but i am not talking about that...). At Least, if you have an reasonable fast Card or Drive, i would expect the Bottleneck to be more inside the Camera in Reading out The Data from RAM/ Compressing / Computing /Whatever happens else to the Sensor data inside the Camera.

According to the SD card specs, we should theoretically be able to achieve 24MB/s on the Chronos 1.4/2.1, but in practice I have never seen any card exceed 10MB/s.

The vendor for our CPU quotes an ideal throughput of a little over 100MB/s for the write speed of the SATA port, but when dealing with filesystem access patterns and overhead we are more likely to see the performance of the SATA interface top out at a little closer to 60MB/s.

Hi,

I did some tests a while ago:

http://forum.krontech.ca/index.php?topic=442.msg2307#msg2307

I guess SATA speeds with very fast random access SSD drives will be even better performing!

All the best

I finally found the time to also print this SSD holder. I forgot to add supports for the print, but my printer handled it very well even without them.
I did some very quick tests an the SSD is about twice as fast as the SD card when saving DNG files, MP4 is about the same. Currently I have it formatted to FAT32, maybe I'll "upgrade" the filesystem to EXT3 or even EXT4 and see how it does then.
However reading EXT formatted Devices from Windows sucks :D


EDIT: I just saw the mounting-holes for the m2x10 screws, what are they for? As far as I can tell the holder works perfectly fine without those screws in there...

The m2 screws are to secure the SATA cable in the SSD holder to prevent it from moving/shifting when connected to the SSD.

Just installed a M2 NVME SSD drive (Crucial P1 500GB) using a external case that connects directly with a USB port (resembles a flashdrive). Testing transfer speed on computer goes as far as 300MB/s for large files.

Tested camera (C1.4) export with DNG, TIFF, H.264, RAW, managed to get only 8fps. Tested on FAT32 and EXT3, no difference...

A bit disappointed with the speed, I was hoping for the 18fps, perhaps Tesla500 has something to add on this.

Should I try a SATAP cable with a "less fancy" SSD (2.5" format with printed case)?

Well, another batch of tests here.

I bought a NVME SSD, so the cheap adapter linked above would not work. Opted to sell this SSD and buy a new one...

Opted for a regular sized 2.5" SSD.

Got much better speeds with this new setup, using simpler (cheaper) parts, tested only Raw 16 bit export and got 13 fps, not the 18 fps stated above, but I can test EXT3 file system and other types of exports to check speeds... Anyway, happy with the results for now.

The question remains whether a M2 (not NVME) would result in better speeds...

as long as the SSD and M.2 SSD are both connected to the Sata-Port on the Camera i would say no or not much better speed, as it seems like the bottleneck for the Data would mostly to be the Interface itself, not the Drives (unless you have a very, very cheap (like Very sketchy Online Seller from China levels of Cheap) or generally pretty slow SSD). but only testing would tell, if that is actually the Case. If the SSD is somewhat recent and reasonable Quality, my guess would be no.

I also think you are limited by the USB ports data capability. As far as I'm aware, the Chronos uses a USB 2.0 port combined with an eSATA Port. If at all possible, use the eSATA connection which is much faster than the USB one.q

DNG saves at about 12FPS on the 2.1-HD and about 18FPS on the 1.4, at full resolution.

 .
 Well, i just read that again, and tesla500 states 12fps for the 2.1 at full res. The 18fps you are thinking about where actually for the 1.4 Save-Speeds.
 So, with 13fps you are allready better than what he said.
 .
 I finally got myself an m.2 with an Adapter (also first got an NVME one, which wont work with the Cheap Adapters, needs to be an NGFF M.2 ...) and i am getting around 10fps Average for DNG; a bit over 10fps (like 10,5 average) for Raw16; about 13fps Average for Raw12; and 25fps Average for H.264 (full Resolution Saves on the 2.1)

Hi There! I have recently acquired a Chronos 2.1 and LOVE my camera! This is my first post on this forum. However, I was very inspired by the 3D printable SSD Cage. I have taken it a step further and buried an M.2 SSD into a handgrip for my Chronos. I have made a brief video to showcase it and (hopefully) attached an image to my post. Let me know what you think:

https://youtu.be/okWUfRP2YLg

I have provided a BOM in the description of the video in case you would like to make your own. I am also prepared to build up a few for anyone who might want one that is plug-and-play.

Tried to have a look at the 3D-File linked in the Video, but both, the Grip itself and the Inserts just lead to an Error-Page. Also the Link for the Rosette and the Standoff seem to be swapped.
 I Personally would want something Protecting that Cable Coming out at the Bottom, so if i set the Camera down or it falls over or something, the Cable wouldnt take all the Stress from that. Extending the 3D-Printed Material Down a bit on the "outside" would do. I would want that material to extend at least 1x or 1,5x the Thickness of the Cable beyond the Point where its Fixed (aka, the Point it would bend from, so the Cable would have at least a bending Radius of something like R=2xD or R=1,5xD, which would be worlds better for that Cable than a Sharp bend at Full Force.
 As Far as Mounting goes, i would use this:
 https://www.ebay.de/itm/255280846968 (https://www.ebay.de/itm/255280846968)
 (Standard Arri-Rosette with a Slot For Adjustable Mounting on 1/4" Holes)
 To mount to the Left Side of My Cage i am Building (see: https://forum.krontech.ca/index.php?topic=683.0 (https://forum.krontech.ca/index.php?topic=683.0) . Just Posted some Updated Images of the Progress there.). That Plate seems Fine and sure works fine if you dont have a Cage, but as i soon have a Cage, that is just More Streamlined. Still need to Tap these with 1/4" 20TPI, would probably end up using the Lower two of these (see Image).

I have a question regarding the disk and cable used. Do you have any links?
Is the enclosure for the disk 3d printed?

I like the small disk but in my setup I would prefer the disk below
the camera like a winder or vertical grip or mounted to 15mm rails
as the camera would almost exclusively  be used in a studio with a 1st assisant
and remote screens.
Have you tested your dis for max dng write speed?

Apologies for the delay - I was traveling. Anyhow, I think I fixed the links...

Your suggestions are very do-able - I like the idea to protect the cable with a guard that extends from the handle. I could modify the design for you if you like.

You cage design is EXCELLENT! However, your rosette mount would only save a few millimeters of thickness as compared to the one I am using. I also don't understand how it will attach to the cage as you need a male base on the rosette and that one looks to be female. Unless you plan to use the slot to screw through - in which case, I think it would work but puts the point of connection well outside the rosette and could prove to be less robust.

Having the disk below, like a winder/V-grip is a good idea. I opted against above/below due to my need for solid tripod mounts and the fact that I wanted a better grip for handheld shooting.

Yes, the enclosure is 3D printed. Below are the links to the drive, adapter and cable I used. I have not tested the drive to find it's speed - it is much faster than SD card though...

thanks for the info

It looks like I will have to get a Blackmagic recorder for my setup as well so I can reply to clients requests and replay earlier shots (no longer on the camera)
In that case I will probably just add the disk to the extra monitor/recorder with a cold shoe or nato clamp

would be interesting to know if the M2 to Sata to eSatap is slower than directly to a 2.5 disk, I am not enough of a compter geek to know if there are any additional bottlenecks...

 Yes, it is intended to just have 1/4" Screws Bolted through the Slot, which are provided with the Thing from the Seller. I couldnt find anything with a Matching Hole Spacing for Two Screws to my Grip Design in the ~20 Minutes i spent Searching for that, but that one will fit for sure, as the Slot makes That Adjustable. I am Very much aware, that this is not the Most Solid Solution Possible, but i first want to see, if i even like the Way that would Feel, Look and Work. And that Adjustable Arri Rosette is a Cheap and Easy Way for me to figure this out without spending a ton of time on it.
 I Have the Tools to just go and Make a Custom one of these any time I wanted, and if i feel like its not Stable Enough, i would end up using Stainless or Toolsteel for such small Parts anyways. Its just a Small Metal Plate with some Holes (and maybe a Slot, but if i make a custom one anyways, i might as well make the Holes to fit my Design), no big deal Really.
 So Rigidity is currently not my Main Concern, as its still Metal, and should be able to take at least some amount of force. Will See after some Time of Testing, if i trust the Thing enough to use it permanently in this configuration, or if i will change it later on.
 .
 Main Goal with that Grip/ Cage Design i am doing there is also to be able to break down the Whole Rig as fast as possible on the Field, and assemble it as Quick as Possible, while taking up as little space as possible for Transportation. I use a Hard-Shell Briefcase (its Like a Flight-Case the Size of a Briefcase, Protected Corners, same Locks, and a really Durable and Comftable Grip) for the Chronos, and that has to also hold a full Set of Prime Lenses, a Small-HD Monitor incl. Accessories and a ton of Batteries, a Wall-Power adapter for the Small-HD, A Ton of Batteries for the Chronos, Cleaning Stuff, some Tooling, SSDs, lot of different Cables, including 5m BNC Cable and a Remote Trigger button to attach to any Normal BNC-Cable (can use that for the SDI-Out of the Small-HD also), Some Chargers, Screw on Filters and Filter-Thread Adapters for the Lenses, a bunch of different Firmware Versions on SD-Cards each A Color Checker, some Mount Plate Adapters, a Exposure Meter and a Speedbooster. And Eventually a Power adapter Plate for V-Mount Batteries also. So Space is VERY limited in there, that Briefcase is a lot heavier than you would expect from looking at it. But really Compact, Durable way to Travel with this Camera.
 .
 Thats why i like to have a as small as possible / Practical version of this.
 This Grip should really help with that, as so far (talking setup time, would use more space in the Case however, but should be well worth it), i just plugged the m.2 SSDs in and let that hang from the eSata-Port, completely Naked PCB and all. Still very surprised, this so far has not caused damage to the SSD or anything else there, that is one Sketchy setup, especially when you shoot in the Rain, anything involving Splashing Water or Snow/ Metal Shavings (usually used at least a Plastic bag to protect the SSD in those Cases, which i taped onto the Drive). Somehow has worked well enough so far.
 That Grip should make this a fairly Clean and well protected setup, and would take just barely longer to setup than my current solution (usually still needing to Plug the SSD into the Adapter for the eSata cable, which in this case could and will be left as one single part for Transportation, while adding the Step of needing to screw that into the Arri Rosette every time). Even if its not as Stable for use as a Grip, that alone, protecting the Drive, would make this very much worth it to have and use.

Having the disk below, like a winder/V-grip is a good idea. I opted against above/below due to my need for solid tripod mounts and the fact that I wanted a better grip for handheld shooting.

 Was also thinking about an Above-Below solution for an External Battery (V-Mount+ Voltage Converter for much longer Battery life than internal ones could Provide) and SSD.
 But the Top is pretty much the Only Place i can put an Monitor onto, and the Bottom also is kind of needed for Tripod Mounting, and even though i sometimes do quite a bit of Handheld Shooting as well, i need to change between a Tripod Mounted Camera and Handheld Shooting very quick and sometimes often, so no time to Play around with removing SSDs from the Bottom or something like that.
 Also, the Center of Gravity on that Camera is already fairly high, when used with an External Screen (at least on some of the Smaller Video Heads i am using, not too much of a Problem on the Big ones), and Putting anything below the Camera additionally would make this much worse for Tripod use.
 When you posted that Grip Design, i honestly still was not completely sure how i would do a proper SSD mount for that Cage, but about where you put it would also have been pretty much the only Place to have it, without being in the Way somehow.
 I Thought about using something like this however:
 https://www.bhphotovideo.com/c/replacement_for/1488834-REG/tilta_ta_bsp_v_g_bmpcc4k_v_mount_battery.html (https://www.bhphotovideo.com/c/replacement_for/1488834-REG/tilta_ta_bsp_v_g_bmpcc4k_v_mount_battery.html)
 With Tripod-Quick-Release Mounts (i am Personally using a Arca-Swiss Style Quick Release System on almost anything) on top and Bottom of it, so i can very Quickly remove it if needed, or just keep it on, and Mount the Whole Rig to the Tripod, for example if Battery is Low on the Camera, but i need to finish a Save or something.
 Also need to figure out how to Rig this Adapter Plate i already have
 https://www.globalmediapro.com/dp/A2HG93/Globalmediapro-VLP-U-V-Mount-to-DC-Multi-Voltage-Converter/ (https://www.globalmediapro.com/dp/A2HG93/Globalmediapro-VLP-U-V-Mount-to-DC-Multi-Voltage-Converter/)
 To that Tilta Baseplate / modify that to Replace the Existing V-Mount.
 For Handheld Shooting it wouldnt bother me nearly as much to have something below the Camera itself, as that would honestly be the Only Place to put the V-Mount Battery where it wouldnt annoy me (besides maybe a Belt-Clip with a long Cable, but that has its own Draw-Backs).
 While i am At it, i might as well add some Way to Mount Rails to the Tilta Thing, or make a Custom new Top Plate for it to replace the Existing one, so i would have a Rig, where i can very Quickly add Rails and a ton of Battery Capacity (even Recharge the Internal one on the Go while Shooting), and just as fast also remove it again.
 But first i need to Finish that Cage. Then i will see how i end up doing all of that.
 .
 @mkonrad:
 That Tilta Baseplate thing might also be a good way for you to mount an SSD, or any Similar Product like this, if you dont mind having it below the Camera and have a big/ Serious Video Head (i sure hope so/ would expect you to have one, if you shoot with RED Cameras and a Flex4K), so the Higher Center of Gravity is not an issue.

Hello everyone, just finished a custom M2 case, it's smaller than the regular one, but still bigger than I expected. Seems that the M2 adapter is to blame here (despite cuting an inch from it already).

If you find one that is smaller please let me know, I'll happily switch for a smaller version...

Nice work! I like how it mounts into the holes on top of the camera.
