Samsung unveils the first UFS memory card set, world's fastest

How would you like it if your expandable storage is as fast as an SSD drive, if you could read a 5 GB movie in 10 seconds, or shoot and write to it RAW photos in sequential bursts? Well, Samsung swoops in to the rescue, as it just outed the world's first UFS cards in the microSD format. UFS stands for Universal Flash Storage and the second edition of this standard is what you can find as internal memory storage in the better Galaxy smartphones.

i'm starting to become a samsung fanboy. they are the only ones who do anything that interest me and they excel in all products.

BTW anyone else find it weird PA didn't put the speed numbers? The 256GB version is faster than the internal storage of the S7 and 6S 530MB/s sequential reads and 170MB/s sequential writes 40,000 IOPS random reads and 35,000 IOPS random writes

Nice! Thanks for the info.

yeah. idk why they would skip the most important part. i mean the title says worlds fastest but they didn't tell us how fast.

Well the iPhone 6S uses the macbook-grade NVMe flash storage so I don't think the UFS 2.0 sd cards would be faster than that. Since the 6s has faster storage than the galaxy S7 (which also employs UFS 2) I am sure to be right on this. But I would like anyone to correct me if my statement is wrong though.......

You're wrong from the get go. The iPhone flash memory is only faster than the S7 in sequential read/write, the S7 UFS2 is faster in random read/write. Since most memory operations in a smartphone are random...

I would have liked your reply if it didn't just pull out the test results from Anandtech's page without reading the reason why the results could be limited. They say it's likely they are looking at a bottleneck of testing methodology as the queue depth for the test was 1. The printed circuit board limitations make it unreasonable to have several NAND dies working together as in a laptop. That could be the reason for such low random read/write speeds. The sequential speeds for tasks such as downloading a movie are record setting though. At the end, we don't know if the random speeds are actually low against UFS 2 or not. I am not a tech engineer to figure that out. But the 6S opens apps faster than any samsung phone so that's what matters than these technicalities i guess!

"But the 6S opens apps faster than any samsung phone" Cause of higher sequential speeds (even then its miliseconds and resolution is also a major point here. Random is still more importanter than sequential in everyday use:https://www.youtube.com/watch?v=RzHp_IBbYYY

Mr. Ordinary I get you; the random speeds for storage types are always more important in most cases. What I want to say is that we don't know if random speeds of 6S are slower than S7's. Anandtech themselves states that the lost of iPhone in their tests is due to some big reason which I stated above. And yes, I also know opening apps only requires sequential speeds. I just want this argument to end as it shouldn't matter to us which storage is the better one. If iPhone is overall the fastest, that's what we and the developers need to consider. Feels good to share and listen to everyone's replies, but the argument is pointless unless our words can make the galaxy faster overall, or we become tech scientists in some way. Everyone should go their ways from now on. Good chatting mr. Ordinary!

Yeah beside when downloading something its mostly all random.

according to anandtech iphone 6s : sequential read=403mb/s sequential write=163mbs

Note 7 going to have supper fast speed as it uses the new ufs

This doesnt even come close to the iphone 6s which is more than 3 times faster, which has mobile classleading NVMe with >=1.7GB/s seq read - so sub-1.3s to read entire RAM (2GB) from "disk". It's weird that noone could match these speeds so far especially that the iphone 7 is around the corner, with probably even faster speeds.

I'll take that 64 GB baby.

Sole supplier + high demand = EXPENSIVE!!! I hope i am wrong, most likely will make Apple storage pricing look like a good bargain.

Samsung won't be the sole supplier The UFS card standard is published by JEDEC (same with UFS, eMMC, LPDDR4, DDR4, HBM, GDDR5X, ...) I expect Toshiba, Micron, SK Hynix, ... to release some soon as well I doubt the 32GB UFS card will cost $100

At least Samsung trying to be the pioneer.

What i want to know if its compatible with current phone with SD slot. If yes will its be limited in any way ( because i found out my LG G5 get much higher speed on my SD card than my old moto x play )

Nope, it's not compatible, it has be a hybrid slot which would support both micro SD and ufs

and if U take 256gig Note 7, then a combined capacity would be half a terra!!! damn it!

Damn Samsung....UFS internal memory + UFS card + Exynos 8893 = speed demon

256GB internal + adopted 256GB card = big fat speed demon, lol..

Yeah, where are the people who said SD card will never be as fast as internal storage?
