Sure the Z30 doesn't have UHS-II, but you can still use those and profit from the faster read-out speed on your PC or Mac. Especially the cheaper UHS-II V60 cards are great in terms of price/performance in that regard.

Cobalt and Gold are different CFx cards for different purposes. The *Cobalt* line is using pSLC NAND Flash (therefore odd capacities like 165 or 325 GB), *Gold* uses normal TLC NAND (256, 512 GB and so on). pSLC is 3x more expensive per GB, because each cell contain 1 instead of 3 bits. But on the other hand much more reliable (p/e cycles) and faster. So if you e.g. shoot 8K RAW video, pSLC is your best bet for uninterrupted videos. For standard video (h.264 or h.265), TLC cards like the Gold series are fine - and much cheaper. Size: Depending on you needs. One will be OK with 64 GB for a day, another may need 4x 2 TB.

@@memory-card Thank you for response. I'm looking the high end choices that my camera gives me just in case. So if want to capture 6K Raw video for 30 minutes i should pick one of the Cobalt line with at least 325gb memory? Where can i check online for the storage of every video mode on my Z6 iii? Theoretically, because if i need to pick a memory card i have to know how much it "costs" every mode i choose. Thank you.

We have no samples from Suneast here, but in theory it should. Everything up to 2 TB is usually fine. 4 TB an beyond can be tricky.

Yeah, but not in the highest framerate. 2160p24/25/30 will work (150-190 Mbit/s).

No, you can achieve 11 fps with any memory card and no, the A6700 does not support CFexpress Type A in the first place.

@@memory-card fantastic! Now I just need to know how 1/8000 fully electronic shutter images look like because that's literally the very thing that keeps me up at night whenever I think of getting the A6700 in a year or so

No, obviously RAW in #1 (CFe) and JPEG in #2 (SD).

Since you can't use those in the Nikon Z6 III, as the camera only supports CFe Type B: No. But we have tested the Pergear in a Sony Alpha 7 IV: www.memorycard-lab.com/-Cameras/Sony-Alpha-7-IV-CFe

V30, V60 and V90 are video speed classes, defining a *minimum* writing speed of 30, 60 or 90 MB/s respectively required for the certification. Just to say V60 card A and B may have way different results, even though both are V60. An example for the A7RV: Both the Lexar 1667x and 1800x are UHS-II V60 cards, but the 1667x is reaching ~110 MB/s during continuous shooting, the 1800x ~180 MB/s. Since the camera starts writing immediately, the "buffer size" (# of shots at full speed) differs. Rule of thumb: 55-65 shots for fast V60 and V90. But lossless compression is recommended anyway :)

Neither nor^^ You don't have to use one SD + one CFexpress, but you can. But it's not a Sony Alpha alike combined slot (Dual CFx A + SD in case of some high-end Sony cameras).

@@memory-card can I use two SD cards at the same time?

No. As written above: one SD + one CFexpress card.

Yeah, same for the EOS R7.

Uff... Hard to answer. Everything up to 2 TB is usually fine, 4 TB and beyond is not supported by most cameras.

@@memory-card oooo....thank you for the reply

That's totally fine :) More information on the website linked in the video description.

No, currently only the X-H2(S) and GFX series.

Could be both, Firmware or Software. And no, we obviously don't have a storage room with 100+ cameras here^^ So we may test it again in 1-2 years, but a fix is unlikely anyway. Also there's no indication in the changelog.

No, the first Z6 is featuring both: No SD card as well as a much slower CFexpress implementation. But we have tested the Z6 as well: www.memorycard-lab.com/-Cameras/Nikon-Z6

Wenn diverse UHS-II SD-Karten nur im UHS-I-Modus laufen, läuft da kameraseitig etwas schief.

Yeah, that's totally fine.

Since when is the Sony a6700 capable of recording uncompressed/RAW-Video (internally)?^^

@@memory-card XAVC S-I Codec is uncompressed easy to use while editing other more compressed and I need to use proxy files and as u know 4K (4:2:2, 10bit) 59.94p (600 Mbps) is really massive files so my v90 card writes it but playback issues when reading...

No, uncompressed 4K 10 bit with 60p would require ~14,930 Mbps (3,840 px * 2,160 px * 3 color channels * 10 bit color depth * 60 fps) or roughly 2 GB/s. XAVC S-I is just an all I-frame encoding - so pretty basic H.265 or H.264, just without P- and B-frames. Since most modern PC and Mac have pretty decent HW decoding, it's just wasted HDD space for 99 % of all use cases. Anyway: The playback issue is weird, since cards are usually always faster in read-mode. But could also be a problem with the Sony Firmware. Maybe there is an FW update available?

Not really. The power consumption of UHS-I/II SD cards is usually between 1-2 W during read/write operation and 0.x mW in idle. Not enough to make it difficult.

@@memory-card thnaks. I have some issues with delkin sd cards v60 uhs-ıı

No, neither the A7C II nor the A7CR have a CFexpress Type A slot.

Was heißt "geht nicht" konkret? Fotografieren solltest Du ohne Probleme können. Filmen nicht, da Sony auf den XAVC-S-Container setzt, der Dateien größer 4 GB produziert und das geht nur mit SDXC-Speicherkarten (exFAT-Dateisystem).

Sure you can. But depending on your camera settings, the actual speed of the card and how many pictures you take in a row, it may take minutes to safe everything.

@@memory-card appreciate this, I figured it out on my a6700 when I shot continuously and it spent 10secs writing photos lol

@@memory-card 256gb v90 on the way lol got a good deal on Amazon for $159 usd

Well, a Nikon D6 has 21 MP and can shoot 14.5 fps and is also using fast CFexpress cards, so the actual buffer isn't that big either^^ A 45 MP Nikon Z 8 with up to 30 FPS RAW or 60 FPS JPEG has a larger buffer, just to achieve a similar number of frames :)

1.) The write speed is measured (bytes written divided by the time the indicator was active). 2.) We are transparent about that fact. You'll find the explanation at the bottom of the G9 II table: *Please note:* _The results above were measured using a Panasonic Lumix S5 II. Based on a 6-point random examination, measured values are applicable to the Panasonic Lumix G9 II as well. The deviation between both cameras is below ±1 percent._ It is common practice for camera manufacturers to use the same type of image processor, image sensor or in this case memory card controller for various cameras. Sometimes the controller is within the image processor. For example, Sony used the same (very slow) controller across almost a dozen early Alpha 7 and Alpha 6x00 cameras. So we do not "assume" uniform behavior, but measure a reasonable sample size (in this case 6 out of 41 cards, so ~14 %), including the fastest card and across various (interface) speeds such as UHS-II V90, UHS-II V60 and UHS-I.

Since there's no CFexpress Card Slot... Nope

Feel free to use our test results as a reference: vturl.de/g/27d :) But as also mentioned in the video: A good UHS-I card ist good enough in terms of write speed.

We do not have an 1 TB card here (512 GB is the current maximum). But technically there is no reason why not. The X100VI supports the SDXC standard, therefore anything within SDXC shall be compatible (from 64 GB to 2 TB).

Yeah, it's probably fast enough for 95% of use cases. It would have been great, if you copy the files directly from the camera via USB-C though.

its a flagship camera so its expensive for everyone lol

After our video was released and the issue forwarded to the SD Card Association, all products mentioned in this video were removed from Amazon, worldwide.

As mentioned in the video, feel free to check out the link in the video description for all test results and hourly updated price/performance recommendations: vturl.de/g/1ze Video is just a bad medium to present such data, especially for ober 80 SD cards.

i hear ya, but its at least worth putting some of your hard work on the screen for relevancy. otherwise, it just comes off as unresearched opinion 🤷‍♂ you've got incredibly valuable info that a LOT of photogs want to learn, but it gets burried by the overly loose & candid style of video and links that look like click-bait traps. not trying to be an a-hole here, but some small refinements to your format and I think you'll see your audience & engagement grow (which I'm guessing is the goal) @@memory-card
