In reply to:

Sacher Khoudari: Is this going to replace SD/XQD cards in the future as well? Is there going to be a bigger form factor?

I won't like to stick those tiny things into my camera, I will be afraid to break or loose it. The SD-card size is actually quite handy if you handle them often. This tiny microSD-alike form factor may be appropriate for mobile phones, but cameras don't have that size issues.

I've dropped a couple mSD and never managed to get one wedged in such a way, lucky I guess, but I assure you it's much easier to apply leverage to a larger and more hollow card either way. A micro card is more likely to stick to the sole of your shoe than to split in half tbh.

William Koehler: Just as SD/SDHC/SDXC has achieved market dominance, someone has to come up with yet another flash card format. Good luck with that, Samsung. Maybe you should ask Sony how well MemoryStick worked for them, seeing as Sony has made almost everything they sell work with SD/SDHC/SDXC.

Just because Samsung is the first to debut a removable UFS card doesn't mean all the other players aren't following suit, and UFS it's already in use within phones and vastly more efficient as primary storage than eMMC solutions which more closely referenced SD formats. You don't know what you're talking about, sorry.

Melchiorum: "Hey guys, let's create another format of flash memory, because we clearly don't have enough of them. It will be almost exactly like the microSD, but just barely different to be incompatible with it. Sure, we could just do the same with microSD, but let's not, because we want to push our own format now! Yay".

Your ignorance and willingness to display it is amazing.

Kiril Karaatanasov: Brand new Memory Stick! Wow! How exciting.......

This time from Korea

And from Taiwan, and the US, and... This isn't a proprietary format, it's already in use in non removable form, and it's backed by all the big NAND makers... So yeah, exactly like Memory Stick, in just about no way possible.

Nick Brundle - Photography: Give it 5 years and it will be standard in most electronic goodies

Sony rolled out few propriety formats that only Sony was behind of, this isn't that, do some basic Googling before commenting on something you're wholly ignorant of IMO.

The amount of ignorance (while fully willing to speak out of their a-- on the subject) and tech phobia on display by most commenters is pretty appalling. The article probably didn't belong on DPR to begin with since it isn't something that's coming to camera bodies anytime soon, but it's Samsung's inane marketing that's dropping the ball in that regard.

wklee: Is this another Fujifilm/Oly xD card in the making, like the Sony M2 memory card was? Remember that only Fuji and Olympus supported the xD cards?

It's actually a standard backed by all the major NAND makers and already in use in non removable form inside phones, tablets, etc. So yeah, nothing like Memory Stick or xD.

This isn't a Samsung standard, it's backed by all the major players...

It irritates me to see a new body that doesn't fully exploit UHS-II, it makes a huge difference as far as buffer clear times, hell it almost makes the buffer irrelevant for certain formats or at least extends it's usefulness...

My E-M5 II can shoot RAWs indefinitely at 5fps using a UHS-II card despite having a pretty meager buffer fully inline with it's midrange status, the camera can just write to the card that fast.

Obviously with larger files you wouldn't quite manage that (tho there are faster UHS-II cards than the Lexar 1000x I have and my camera can use), but it's still extend any buffer by a few shots as it's able to clear some before a burst ends, and it can cut total buffer clear times in half.

XEddieX: Yes, this will sell very well, just ask Sony.

This is backed by all major NAND manufacturers, already used internally in phones and other mobile devices, and pretty much the opposite of a pointless proprietary format like Memory Stick. It's also not gonna be relevant on cameras for years anyway... Publishing this kinda story on DPR just seems to cause confusion, consternation, and uniformed commentary (no offense)... Dunno why Samsung's PR would send it over or emphasize cameras within the release tbh.

" I've been doing USB transfers without removing memory cards since the beginning of my entry to digital photography. "

Eh, I might've said that was a decent precaution back in the day of fragile CF pins... But these days it's just a really slow way to offload photos. Even cameras with USB 3.0 (still a rarity unless you're using pro bodies, which already had Ethernet etc) are still usually much slower than a decent USB reader compliant with the latest standards ($9).

Plus it also puts your camera batteries thru extra cycles and heat...

They're probably not aimed at cameras despite the inane PR blurb, see previous comments.

Smaller cards are probably harder to break tho, there's less empty space in them and they're built to tighter tolerances... All my SD cards have at least a tiny amount of flex and visible seams, micro cards usually look like one solid piece of molded plastic.

You probably have a point about handling, tho consumers really shouldn't need to be handling cards in the field... Pros with runners and assistants are another story.

In the long run, cameras will probably benefit from the internal space gained by moving to a smaller format (specially mirrorless) but i don't see it happening in the immediate future. Half the camera makers haven't even fully adopted UHS-II SDs... Some will employ it for 4K then not for stills (cough, Panasonic buffer clear times).

Then pro cameras are on a completely different track... So yeah.

Psql: Not that fast with the write speeds and not correct info from Samsung. For example the new Lexar 1800x UHS-II microSD has 245MB/s write speeds. Only the read speed is lower with 275MB/s. But for high speed bursts the write speed is more important and the Lexar looks quicker.

In tests with 1000MB writing to the Lexar has a speed of 222MB/s. That is way quicker as the 35MB/s Samsung mentions.

See: http://www.cameramemoryspeed.com/reviews/sd-cards/lexar-professional-1800x-uhs-ii-32gb-microsdhc-memory-card/

It's just pointless marketing fluff, it's even more pointless that the story is at DPR at all... Marketing departments love big numbers. Even PC SSD are largely marketed on the basis of sequential transfers despite enthusiasts knowing better and SATA being a 500MB/s bottleneck for years.

Then came PCI-E/M.2 drives and they still brandish 2,500MB/s sequential or whatever all over the marketing materials, even tho the only way you take advantage of those sequential speeds is with another SSD (or an array of slower ones), and even then you'd fill a drive lickety split at those speeds. :p

Marketing finds 2,500MB/s vs 500MB/s and 250MB/s vs 35MB/s a lot sexier than harder to explain concepts like IOPS or smaller numbers representing random I/O like 50MB/s vs 5MB/s or 7ms seek time vs 0.001 or whatever. :p Non removable UFS implementations have already been in use inside phones for the last year or two.

TonyPM: Why make a new format when you can make the existing format better?

What will happen If micro SD manufacturers make those as fast as samsungs new format but cheaper?

It's also not like Samsung came up with this standard and form factor on their own... First off, Hynix, Micron (who owns Lexar), Sandisk, and other major players are all behind it...

There's only about 3-4 major NAND manufacturers who produce all the flash other brands and sub brands use to build flash media like SD cards, and they reserve/price higher grade NAND in a way that only allows it to end up in higher end products (PC SSD, RAM, etc). Removable flash media is pretty far down that pecking order, and no random rogue OEM is gonna come up with a "better mSD".

Lastly, non removable UFS packages have already been in use in things like phones, where you're running a full OS and IOPS matter. Basically the story had little relevance at DPR outside of the vague promise that cameras will someday use this, maybe, when it's cheap enough.

The write bottleneck is on the client/camera/controller side, or more realistically, in thermal limits. With a decent enough controller, just a little room, and enough parallelism you can push flash storage to speeds upwards of 2,500MB/s (see: gumstick sized M.2 drives used on 0.5" fanless laptops). You're still making the mistake of comparing sequential speeds which isn't really what these are about, but they're probably not aimed at cameras anyway... Cameras don't really need ultra high IOPS.

BTW, the other flaw in the comparison of sequential transfers like that is assuming any SD card can actually reach that speed with <50MB files (let alone 5MB JPEGs), vast majority (if not all) won't... They'll reach it while transferring a large video file in or out (sequential), but smaller files quickly drop transfer speeds, even on a high end desktop SSD.

Joe Ogiba: I bet the Samsung S8 smartphone with 4K video will have a HFC slot when it comes out February 2017.

Probably not, unless these are really cheap by then which is doubtful... Samsung hasn't even jumped on USB Type C. They're pretty cautious not to upset the masses...

Might wanna re-read that bit, Samsung was comparing their card to a random UHS-I card which would manage 35MB/s... They say theirs will complete the same op in 7s vs 32s (at 35MB/s)... Although if you extrapolate (32/7 x35) that's still "only" about 160MB/s.

Either way these are pretty ambiguous comparisons of sequential transfers, which probably suffices for a camera (specially as files her larger and/or if shooting RAW), but based on the specs and the IOPS ratings this would kill a regular SD of any kind at random I/O...

Those usage cases would tend to be more common on a PC or smartphone, but they're THE most common scenario in that space.

SSD don't destroy HDD as boot drives because they manage 500MB/s sequential read/write (vs maybe 100MB/s), they're a large leap forward because at random I/O and with smaller files they're 10-20x faster, not just 5x faster. So the usage case for these cards won't necessarily be cameras unless they completely supplant SDs.

That's not true, at all, both Oly and Panasonic have touch AF implementations that work with your eye to the EVF... It sounds a little scary at first but it's really no different than using a touchpad on a laptop, it works.
