Atoch C2S CFast to SSD Solution for Blackmagic URSA, URSA Mini, and URSA Mini Pro (4K & 4.6K)
Key Features
  • Supports the Blackmagic URSA & URSA Mini
  • Supports the URSA & URSA Mini 4K & 4.6K
  • Supports the URSA Mini Pro
  • Equipped with Dual 2.5" SATA Drive Bays
The C2S CFast to SSD Solution from Atoch allows users of the 4K & 4.6K versions of the Blackmagic URSA and URSA Mini, as well as the URSA Mini Pro, to record footage captured by their camera directly onto SSDs, as compared to CFast cards. Operating as a "digital bulk loader," the C2S has two 2.5" / 9.5mm SATA drive bays, each of which is equipped with a wired CFast adapter that plugs directly into each of the CFast card slots on the URSA, URSA Mini, or URSA Mini Pro. Each 2.5" drive bay supports SSDs up to 2TB, for a total storage capacity of 4TB, or the equivalent of 16 x 256GB CFast cards. Not only will the C2S negate the need to carry around multiple CFast cards, users will also be able to swap out drive media less frequently, as larger capacity SSDs are a more cost-effective purchase than CFast cards.

Atoch C2S Overview

The C2S CFast to SSD Solution from Atoch allows users of the 4K & 4.6K versions of the Blackmagic URSA and URSA Mini, as well as the URSA Mini Pro, to record footage captured by their camera directly onto SSDs, as compared to CFast cards. Operating as a "digital bulk loader," the C2S has two 2.5" / 9.5mm SATA drive bays, each of which is equipped with a wired CFast adapter that plugs directly into each of the CFast card slots on the URSA, URSA Mini, or URSA Mini Pro. Each 2.5" drive bay supports SSDs up to 2TB, for a total storage capacity of 4TB, or the equivalent of 16 x 256GB CFast cards. Not only will the C2S negate the need to carry around multiple CFast cards, users will also be able to swap out drive media less frequently, as larger capacity SSDs are a more cost-effective purchase than CFast cards.

In dual card mode, the C2S supports up to 4.6K RAW recording at 60 fps. In single card mode, the C2S is able to record compressed RAW video at any resolution at all available compression levels, which are 3:1 for the 4K sensor and both 3:1 and 4:1 for the 4.6K sensor, as well as all available resolutions and frame rates of Apple ProRes. Additionally, when used with Atoch's recommended SSDs, the C2S supports a greater maximum data rate than the 4.6K version of the URSA and URSA Mini are designed to output.

The Atoch C2S has helped to trim costs and streamline post-production workflows for many projects. This device is powered using the included D-Tap to DC cable and for those who wish to use 7mm SSDs within the C2S' 9.5mm drive bays, two SSD spacers are also included.

General Features
In-Camera SSD Control
Use your camera's user interface to format, record, and playback your footage just like you would with a CFast card. Even though CFast card sizes are limited, your URSA, URSA Mini, or URSA Mini Pro won't know the difference between your inserted SSDs and a CFast card inside the camera, even all the way up to 2TB
Universal Ergonomics
With a 0.25" threaded mount on the underside of the Atoch C2S, it can be mounted as easily as almost any field monitor or external recorder. And with the use of a magic arm, the Atoch C2S can be swung around to nearly any position around the camera for improved ease of use for virtually any shooting circumstance. No need to permanently make your camera longer or wider, possibly making your shooting experience unwieldy, or causing issues on a gimbal. With your choice of magic arm or ball mount, your Atoch C2S is configurable to your specific shooting style
Universal Power
The Atoch C2S takes 12-24V directly and Atoch supplies a D-Tap cable so users can connect it directly to their battery or battery plate; whether you use Gold Mount or V-Lock batteries, the Atoch C2S can be powered with ease. With an LED-verified power switch, users can also see when their Atoch C2S is functioning properly, and even switch it off to save power
Fanless Cooling
Designed with audio in mind, the Atoch C2S helps keep your SSDs cool by allowing natural air to pass over and under your drives. There is no need for any additional power drain from powering noisy fans
Secure Drive Grip
Inside of the Atoch C2S is a SATA connector which grips SSDs tightly and without risking damage to its pins. There is no need to worry about SSDs falling out or remounting them when they've been jostled or bumped on set. The Atoch C2S is well suited for run and gun productions
URSA Mini Pro
Both CFast ports on the URSA Mini Pro are compatible with the C2S using Western Digital Blue SSDs, SanDisk Ultra 3D DDSs (not SanDisk Ultra II), and Digistor Professional Video SSDs.

Atoch C2S Reviews

SLOT 1 for the SSD cards FAILED ON ME

By Wonder
Rated 1 out of 5
Date: 2021-09-09

I cannot record anymore on SLOT 1 SSD because for some reason I get frame drops and then it stops recording. Usually it might last 2 seconds then it stops. Sometimes it might last up to 20 seconds then it stops again. When it's recording you'll get a RED dot with an exclamation point, then the recording stops right after. when looking back at the footage, it gets disappointing. Visual glitches, frame freezes and doesn't pick itself back up again. Do I recommend it? BIG NO, take a visual look at it. It's so freaking cheaply made.

Second unit in a row that has a bad slot #1 (doesnt work)

I REALLY wanted to give this a good review, the first unit I got had a bad Slot #1.  Couldnt get it to work and had to shoot the entire shoot only using Slot #2.  I sent that unit back for an exchange.   The replacement (2nd) unit came in and I had high hopes that it was going to work.  Slot #1 fails whenever you try to move the camera!  So, I guess this solution would work for a camera setup where you dont need to move your camera?  (Forgot to mention Im using this for an URSA mini pro)  Obviously, I have to move my camera because thats how we make money.   Either way, this was the second unit with the same problem: bad slot #1.  Slot #2 on both of the units worked like a charm though.  Overall, Im really disappointed with this product and would give this a 0 star rating because it just doesnt work.   I just got of the phone with the genuinely wonderful folks in customer service at B&H and Im mailing this one in for a full refund.  Guess its back to CFast 2 cards and shorter record times.

We bought this as a solution for our BM Ursa 4.6K for our film students to use. We have had two units fail over the last two years. I just bought a new Black Magic version of this SSD recorder, as their items tend to be more robust. That is what I recommend.

Perfect !

Works perfectly fine with 2 Transcend SSD370S 1 To on Blackmagic URSA V1 ( For an amazing shoot capacity of 2To !!!) Stars in my eyes ^^

An expensive resolution to an even more expensive storage.

Let's face it. If you want to get away from the expense of CFast and go for a more readily available SSD medium for your Blackmagic camera, this is the only way to go. At the end of the day this just works. You plug in all the connections, turn the thing on, bing bang boom, the camera is good to go. 1) I recommend formatting the SSD drives in the camera first to make sure recording things are smooth. 2) Research SSD's and write speeds versus the resolution/format you want to record in first. No two SSD's are created equal and write speed does matter. Now the downsides. The biggest problem with this is that the CFast ports are under the viewfinder door. Meaning, the 10 viewer finder will need to remain open while the CFast cables are plugged in. If you use the screen anyway, this isn't a problem, but if a shoulder rig is your jam it might be a pain. Additionally the price of this guy is a little high for essentially a port converter. However, you don't have a choice since there isn't anything else out there like this, and if you can afford a Black Magic camera most likely cash isn't your problem.

2 lemons in a row--test your purchase throughly b4 keeping

Bought this product with (very high hopes) for work with my Ursa Mini Pro. First one had a drive slot #1 that just would not work. Sent it back as and exchange and got a brand new one. The exact same problem as the first one! Sent that back along with the Hard Drives. The second drive slot did record correctly but the first drive slot would show that it had a drive ready to go, but would record for a second and then stop. It was not a hard drive problem, because I could take the drive out of the 1st slot and move it to the second slot and it would record just fine. What's the point of 2 slots if they don't both work?

question

Minimum accessories needed with this-dr asok
Asked by: Anonymous
This product comes with the D-Tap cable which will allow you to power it off of the battery you are using with the Ursa. From there you'd just need a way to mount it to the camera, such as B&H # IKMA207, and Solid State Drives to record to, such as B&H # SASSDXPS960.

question

With this mounted on top of the URSA Mini, is there enough space for it to sit on a full size Ronin without bumping the top of the gimbal enclosure?
Asked by: Anonymous
We strongly feel this would not be possible to do. We recommend using CFast cards for when you are are on the gimbal. That will be smaller, lighter, easier to balance.

The combination you are asking about is unknown. We would have to say that it would be unsupported by either manufacturer and using it would be at your own risk.

question

Anyone know if it's possible to use SanDisk Ultra II SSDs with the unit?
Asked by: Joe
This unit does not support the Sandisk Ultra II SSDs. Because of the speed requirements needed to record the files that the Ursa/Ursa Mini 4k and 4.6k cameras create it only supports SanDisk Extreme Pro and Samsung 850 Pro Solid State Drives.

question

Would this adapter work with non-Blackmagic cameras that use CFast cards, such as the new Canon C700?
Asked by: Michael H.
As I recall it will not work with the Canon cameras because they have a cover over the card slots that needs to be closed for the camera to recognize a card. At least this is the case with the C300 Mk II, I'm not sure about the C700. The cables prevent the card slot cover from latching.
