@ Samuel Lucifer: A quick Google search tells that CFexpress is a standard proposed by the CompactFlash Association. @Sup YallIf you are shooting with camera like A1, cost of a memory card probably shouldn't be even a concern? The capacities are clearly lagging behind. Comments on this article may be moderated before they are made public. Nothing more proprietary about it than SD/miniSD/microSD, except Sony is the only one that's bet on the CF-A form factor. Well its not that much cheaper vs Sony's offerings and V90 SD cards takes care of most things and as far as functionality is concerned, there's no lacking with the SD cards. Seems like it could be handy and fast for when you need speed, and offload from the SSD to a computer or SD card later when speed isn't important. Its specifications namely are the exact same as Sony's own. I must confess, despite 45 years in the technology industry, and despite some familiarity with Cirrus Logic and Lexar, I'd not yet heard of ProGrade. Comments for which I thanked them. So I don't need more than 128GB, nor do I need that write speed since I am not doing video. m.2 is just another form factor that is designed for internal use and not to be replaced often, it has rather delicate connector and needs to be secured with screw. They thought people would want to use their SD cards for a while yet, especially the more expensive ones that pros tend to buy. I guess I should have been more specific that I was mostly thinking about a "Why not both?". Build in memory for phones is fast because it's natively integrated into the chipset data lanes and SD cards were historically pretty slow, with old interface. If M.2 SSD can't built-in in camera, why not make M.2 SSD slot built-in in camera's hand grip? If you knew the history of this company you would know why they legitimately call it ProGrade. Sony charges $200 for the 80GB card a whopping $400 for the 160GB version, but you can now pre-order the ProGrade 160GB version for a more reasonable $330. For you CFE-A cards are the better solution as you articulated. In fact given the prevalent use of SD over CFE-A in some very high powered cameras by some very skilled users, one has to wonder if CFE-A even offers that much of a real world advantage, or if it's just marketing hype. We could be carrying 10-20x larger drives than this CF-A card with 5-10x the speed for the same price. Better yet, you can get the new ProGrade card in a two-pack for $590, increasing your savings to $210. Thats performance and reliability combined with the compactness bolds well for the continued use of Type A. Im an A1 user and I do use cfa for one reason; I shoot stills and video clips on the same jobs and often have to quickly grab a video clip after snapping stills. When you purchase through links on our site, we may earn an affiliate commission. @ panther fan: You can copy data from one card to the other after shooting a sequence. Even if I had an A1, I would not be spending +1k on storage. At 400MB/s, the card can record video across a wide range of codecs and resolutions, including 6K ProRes 4444, 8K ProRes 422 HQ and more. "because when your camera costs 6500 the 590 you spend on the cards shouldnt matter. If someone release battery grip with built-in M.2 SSD slot will sell.. M.2 and CFExpress are both form factors. You only need 512GB - 1TB cards when shooting RAW if you're holding the shutter button non stop, but I've seen that happening only to amateurs. CFExpress is the future. Prices vary between countries quite significantly at higher capacities, and ProGrades Cobalt series CFexpress cards appear to offer the best continuous write performance available in 2020. Why!? Add an m.2 slot in camera and call it a day. If you need more speed than V90 you record 8K+ and probably have a decent camera rig. Designed to speed up your workflow, eliminate obstacles that may limit your creativity, and give you peace of mind. Have to send camera back for repair? The Sony cameras wont let you start recording a video until the buffer is cleared, and with SD that can take 8 or 9 seconds to clear instead of 1 or 2 seconds with the cfa. Well with the CF type A you could have 1 SD and 1 CF in one slot so potentially you could save real estate on the camera while still having redundancy but it still has terrible dollar for capacity and not much capacity to begin with. Matthew is available to hire as a DP in Japan or for work anywhere else in the world. Below show M.2 SSD slot built-in in USB hub.6:30 https://youtu.be/Zoaum42hGyA. They are effectively PCI Express SSDs but with a different connecter and an astronomically higher price while offering lower IOPs than many budget m.2 NVMe offerings. I'm less motivated to do so with yours however. Luckily you can still use regular SD as well.The question is more, for how long. @Alam12 "why use 2 if 1 never fail? Speed losses when doing something like shooting video are much lower in a well-designed CFexpress card. Meanwhile, the Sony Tough CFexpress series, based on the Type A standard, offers burst write speeds of 700MB/s, and sustained writes at 400MB/s. SanDisks highly regarded Extreme Pro series are a solid mid-price option, and will be the first choice for many. The Sony and new ProGrade cards each offer maximum read speeds of 800MB/s and top out at 700MB/s write speeds. While the CFexpress Type A format is smaller than the more ubiquitous SD card and up to three times faster the format has struggled to take hold, for two reasons in particular. This card also takes advantage of an NVMe PCIe 3.0 host controller interface. The Sony system is really smart with double duty card slots for SD cards and CF express cards in such compact format. The Long Gop 120p on the A7siii is pretty much good enough that you don't need the All-I option that is allowed with the type A. The card is resistant to temperature extremes, shock, vibration, and X-rays. The only difference is that CFExpress is only PCIe 3.0, and 1/2/4 lanes for A/B/C, while there's (up to) 4 lanes of PCIe 3.0 and 4.0 (which is 2x faster than 3.0) for M.2. If I use media card, I can also use that in multiple cameras if I want. Agree. now, compare the size of the BMPCC to a Sony ILC. They need to give those cameras M.2 slots rather than CFexpress, or make a connector passive adapter that are more robust for the wear of repeated insertions. ProGrade announces $330 160GB CFexpress Type A card with max read And you get 1TB for around $200. I think when you consider that these are simply an upgrade option for power users, you start to realize that they are not meant for everyday Joes, and then the price makes more sense. Theres still a question mark over Type C cards in general, before we even think about the next CFexpress standard. Because we need six of these $330 cards to have 960GB (for $1980 in total). The SD Association, the organization that administers SD card standards, has come up with an alternative to CFexpress. Or perhaps you are offering us a new and unfamiliar usage of the term "need"! Does Sony just have a blind spot for storage? In the early days of computers and digital cameras, proprietary was the norm everywhere. First, Sony is the only camera manufacturer that currently has cameras with the slot and support to use the media. It's fragile format, and sadly 2 card slot is became a norm, why use 2 if 1 never fail? For the price of that 160GB CFexpress card, you can get a 2TB M.2 NVMe SSD with a read speed of 7GB/s and a write speed of 5.3GB/s. Key Features. Hey look at that, our first agreement;)I did mention that SD are fine for professional use scenarios, and fully agree with you. . Many excellent photographers who know what they are doing are using the SD cards and are not seeing their work compromised in doing so. Even raw video is much less than 7000MB/s. If it does then you made a mistake at the 6500 part, not the 590 part.". Using these half baked technologies just makes no sense at all. So maybe Canon will switch to Type A as well in the future, to redce their overheating problems. So far it seems that most are just using SD. That's an absurd claim. And you illustrate perfectly why CFE-A is not taking off in the market and hence why costs are not being driven down. But they are more reliable than SD cards. Delkin Devices Unveils 80GB and 160GB CFexpress Type A Cards SONY Cfexpress type A 80GB // moorlandsafaris.com Why do they need to make the CFX twenty times more expensive? This performance is good enough for ~95% of A1 shooters and therein lies the problem. All three formats. I am not sure why Sony made SSDs are important. By calling themselves ProGrade, the implication is that everything they ever make will be pro grade, because they say so. There's someone active on these discussions who has an A1 and uses SD cards. so how do you feel about Sandisk and their EXTREME to the max lines? With internal SSD I am limited of courseso that the storage I pay for is less flexible in usage. The real question is why did other manufacturers choose the larger, less flexible format? Otherwise the actual memory chip will the same, no matter if it's in USB-C, m.2, or CFExpress form factor, that's not the issue here. You can also get it in a 2-pack for $589.99 USD. It only takes 10-20sec to fill (or copy) such card at its max speed. What about spending $10 for one spare battery too? Tell that to all the nikon guys frustrated that Nikon only put 1 XQD slot in their initial Z series cameras. Matthew has won 48 ACS Awards, including five prestigious Golden Tripods. MikeRan - those XQD slots in the initial Z have been made 100% compatible with CFexpress. What if someone wants/needs more on a single card? Perhaps it's because I've not been in the market for CF Express cards in the past. BMPCC 4K/6K support M.2 SSD via USB slot on camera. A 256GB v90 card holds about 4400 compressed RAW files from an A1 and the camera still shoots at 30FPS and the buffer clears at a rate of 5 frames per second. Need to give the A type cards some more time. For type A cards too, prices will drop, speed will raise, and compactness will stay. We explain the new kid on the memory card block. This is usually a celebration sequence that goes on longer than a normal play. An m.2 drive needs no frequent replacement. They have been doing this since the days of Betamax, Sony does it because they don't just sell cameras, arguably cornering the storage medium has the potential to net way more profits.

CFexpress cards look like a pocket-drainer at first glance, starting at $199.99 / 210 for 80GB. The answer is that we need to build a SSD into these cameras instead of paying outrageous amounts for flash memory. It all started with memory stick, memory stick duo, and then memory stick pro.

This is madness. @Magnar WFor idle power consumption modern high end SSDs are pretty low at around 20 to 30mW. Why are not cameras using m.2 SSDs? They don't make 32 gb anymore for xqd or cfx, the cheapest is a 64gb for $100. You can offload to any external storage when done. WTH!? OnePointTwo.thier is a lot of things in life i can afford but don't buy because the price they are are not good value to me or my use ..i pay 2.25K for my R6.. in the UK canons batteries are 115 but i refuse to pay that .. does that mean i should not of spent the 2.25K on the R6? And if they need the speed they can use Dual CF Express cards. Pros know when to press the shutter, and that way they save a lot of space, and also there will be fewer photos to cull, which accelerates the workflow. I guess when they took over ownership of Lexar, they were hoping to eventually lose the Lexar name. @Sup Yall has the right point. As a reminder, CFexpress Type A uses the same high-speed CFexpress technology as the type B cards, so the Cobalt card can deliver burst read/write speeds of 800MB/s/700MB/s and sustained write speeds of 400MB/s. ProGrade CFexpress Type A Cobalt Memory card - Newsshooter ProGrade appears to be the model where they first offered a premium product and then wanted to expand their potential market downward. An IP57 rating also means theyre highly water and dust resistant. Fourth, it would make it harder to sell the camera, and you'd have to do a complete overwrite to prevent someone else recovering your shots. They are more expensive than the faster CFExpress Type B cards and of course, certainly more expensive than SD cards. You may have heard: theres a new kind of memory card in town, and its called CFexpress. But that'ts not what ProGrade is doing here is it. I have been waiting for these reasonably priced cards. No need to format the card right after you copy the files to your computer (unlike most people do). I'm usually with you, such a name makes me sceptical but they're fine. The key is how many of each type of photographer is out there. These cost $199 / 279 (128GB), $399 / 449 (256GB) or $599 / 699 (512GB), and come with a lifetime limited warranty that covers failure, but not wear-and-tear or you accidentally snapping them. For consumer targetted part of market it would tottaly make sense, but manufacturers like to sandbag the lower models so they are writing memory slowly on purpose. Its been a year where they mostly were out of stock, especially the 160Gb version. If SSD fails, then what? I mentioned the A1 because some people seem to think because the A1 shoots 8K and because the A1 takes CF-A cards that CF-A cards are required for 8K. @ trungtran: You have to save money somewhere after buying a Sony A1. To me, the z6 and d750 file size and speed are almost the same so a cheaper 32 sd card works great for still photographers. Perhaps they had too much nostalgia for the old large and bulky CF cards, which is a format that I don't recall Sony ever supporting. ETOU-tvilProGrade Digital () COBALT 800R CFexpress A Why can't we have some reasonably priced 512GB or 1TB CFX? They have storage oddities across their lineup: the APSC and RX cameras are still crippled UHS-I/Memory Stick Duo slots, the third generation FF MILCs were one fast one slow slot, and now they've standardized on a slower, pricier card type. And as a result, two commenters were kind enough to clue me in about their actual pedigree. @PredatorsPrey, @ewelchThanks for the context. With its Tough branding, Sony's card boasts some impressive durability. Many more "everyday Joe's" will use that model over the A1 or A7SIII. But just as SD more or less steamrolled Compact Flash for years, it seems that CFexpress has already won this fight and its use in cameras like the Sony A7S III is proof enough. As for CF-A vs CF-B it's one lane in a 1568mm^3 form factor vs two lanes in a 4360mm^3 form factor. Sony's adopting CF type A is probably a precursor of what is to come, their use on the A7S3 and A1 seems more like testing the waters, at least you're not pigeonholed into using them. To be fair, to save space I suspect. SD cards are everywhere and I'd think they will beat out CFExpress Type A, B And C. That leaves little future for Type A. I feel like the company is determined to be as far behind in storage as possible, from their crippled UHS-I implementation on their APSC/RX cameras to their mismatching UHS-I/II cards on their Gen 3 bodies to their exclusive use of CF Type A. As soon as they have been in stock they have been sold out again. Nikon Z fc Hands-on Review: Is Nikons stylish new camera more than a pretty face? They are not optimized for embedded use and the shortest form factor has only couple models to choose. Business-wise, it's a smart move - people can't complain much because each slot still supports the fastest SD cards, but Sony benefits from selling the (MUCH) more expensive Cfexpress cards that only they currently make. It is not about CF Express A. Accidentally formatted a card, or deleted a photo, or dropped and lost the card somewhere. The way BMPCC cameras record to external SSD's over USB-C is a good start tho to incorporating consumer drives as storage options. And I think 8K does require them. Much better deal. The other A7 cameras I am not sure. i think I sued to spend $30 for sd card on sale, not $330. The size of cameras will keep shrinking when technology advances (for example in few years they will get rid of the mechanical shutter completely) and dual Type-B is just a pain in the ass. The marketing department rarely thinks past the current and next model, so they come up with naming schemas that won't last. Anyway Id like to see your reliability data on SD compared to other formats, especially if you consider the tough-type fully molded parts available from a few manufacturers they are virtually indestructible mechanically. I think that's a fair summation: that right now CFE-A is for a very narrow niche. But things are about to get a little more complicated.
