Samsung T7 Touch Portable SSD

PostWed Apr 29, 2020 3:45 pm

Hi,

Does anyone know if the Samsung T7 Touch SSD works with the MBPCC 6K, and whether it's faster than the T5 to the extent that it can be used to record in 6K RAW?

Thanks

If it is not in this list, it is not recommended: https://www.blackmagicdesign.com/support/faq/59026
Just because a drive or disk works, does not mean it will work correctly or reliably. A new release of a drive, while it appears to be an upgrade, may have a different FW that may or may not work correctly on the camera. All portable SSDs are really computer portable data drives, and were not made for the demands of video recording. That said, some are good enough, that they work.

On the other hand CFast cards were designed for video capture and work more reliably, and are the recording media of choice for my use.

The Samsung T7 was only launched three months ago and we don’t know whether Blackmagic has even tested them.

B&H says that these SSDs should work with the Blackmagic 4K/6K, but I haven’t read of anyone trying it.

Recognising that the limiting factor is read/write, I think that the question is whether these SSDs are more efficient than the T5 SSDs within those limits.

That was my point, it is a new, relatively untested (it may be in the process of being tested) drive. Use it at your own risk, at this point, then perhaps you can post your results here to help others... :roll:

It looks like inexpensive and fast (double the speed of T5) SSD. Not sure how the finger print reader would work with the camera?

Would be nice if BMD test it.

My understanding is that a non-fingerprint version is imminent. I’ve also read, but can’t confirm, that the fingerprint feature can be disabled.

I can share that the T7 is not working my Video Assist 12G HDR. I was able to format the drive attached but within milliseconds after starting to record it flashes a red ! in the lower right corner and stops, resolution/codec/framerate doesn't seem to make a difference.

I have no problem copying files to the T7 when it's attached to my computer at 600MB/s+.

I bought this T7 disk and connected to the new one BMPCC6k.
Just in case I upgraded camera's software to the new one.
But unfortunatelly it doesn't work.

Camera recognizes it but you can not record anything, even a second.
If you press record button you get error immediately.

I don't know what's going on.

Guys, as Kristian Lamp has pointed out, the T7 is Not on the BMD approved media list. Get the T5, which has been tested. The Samsung specs are for computer packet writing speeds, not continuous video recording.

Thanks Denny - we realize that. As many SSDs not official on the list do also work, it was worth a shot. I would think it's a reasonable assumption that BM will add support for the T7 in the near future, being the higher performing successor to the T5. Perhaps they are waiting for the non fingerprint reader model to be released...

It has to be frustrating when a vendor offers a product that is so much better than its predecessors and yet it fails as you discovered when applied to BMD video. These very large manufacturers are targeting the typical computer user and I’m confident they don’t own recent BMD cameras to test their products for suitability.

I’m not saying this is the case with this particular drive, but vendors have been known to base their claims using data that fits within a limited high-speed cache or performance that is only sustained when a fraction of the drive’s capacity is used such as the first layer of a multi-layer cell design. BMD testing uses the entire capacity of all cell layers.

For those needing a comparable product, please consider the Wise Advanced Portable SSD or similar product as they do own the new Pocket cameras and they verify they’ll work. I believe Angelbird also tests their products with their BMD camera.

I don’t like sounding like a broken record, but I’m hoping folks that are considering this type of solution will make their purchases according to BMD’s approved drives or based on Wise Advanced or Angelbird’s own assurances of compatibility after their own testing with BMD cameras. Sometimes the least expensive solution isn’t a solution.

Sorry, but you have got this the wrong way round. BMD firmware supports a specific class of recording media, and has chosen drives that meet BMD’s recording standard, not the other way round. Camera FW is not tailored for any specific drive, but rather for a drive that can provide the sustained writing throughput recording a continuous video requires.

BMD tests specific drives, and determines which ones will work with BMD specifications, then those drives/cards are added to the list. It appears the Samsung T7 didn’t pass the test, and is not suitable for recording the high bandwidth video signal from BMD cameras. Yes not all SSD cards have been tested, but quite a few have been. Some non-tested/approved cards Work for some recording applications, normally for short takes less than 10 minutes, but I would not put a project or job at risk using one, just to save a few $£€.
Time to move on and get a card that is on the list.
Cheers

I must have missed that, could you point me to where they shared it "didn't pass the test"? It's certainly not for the lack of throughput capability of the drive...

It could be any number of things that BM's USB mass storage driver are currently incompatible with, USB 3.2, fingerprint reader etc etc, so no, I don't think I have it "the wrong way round".

I have a couple of T5s that works just great... and is on the list.

I do not know why the T7 did not pass muster, but for whatever reason, it does not work. Your comment about BMD should update camera FW to make a particular media card work, is not the first time. This came up last year over the changes SanDisk made to their Extreme Pro SD cards, and they no longer worked. BMD started then, they work with media manufacturers, providing the specs needed for BMD compatibility, and camera FW updates were not the solution to incompatible recording media.

I didn’t intend to be sharp with you on this, my apologies. Yes, the T7 issue could be the USB interface, the fingerprint security feature, or a host of reasons, which prevents it working. Since their are SSD drives that do work, and have been tested, I was just suggesting using one on the list, which is why BMD created the list. Not all SSD drive, or all SD cards are going to work. This has been the case since the first camera was made, and the first Hyperdeck recording to a SSD drive was released.

Samsung has now released the T7 without fingerprint verification: https://www.macrumors.com/2020/05/19/sa ... -launches/

B&H has it for preorder, $20 cheaper than the “Touch” version: https://www.bhphotovideo.com/c/product/ ... e_ssd.html

Capacities up to 2TB.

I’ve been changing from hard drives to SSDs for external storage, except for backups/archives, for the last 18 months, and will be purchasing one or two of these.

Ah that's interesting, let's see how the T7 plays out in the future, more hopeful for the sensorless version.

B&H now has the no-touch Samsung T7 in stock. It's selling the 1TB T7 for US$200 and the 1TB T5 for $180. The T7 is much faster.
