SD cards UHS-1....got some questions

Alright, so I have seen these new SD cards that are the new UHS-1 speed class and I was wondering if anyone has seen a crystalmark speed test on them. I know they can write and read fast....at least in sequential but I was wondering about random speeds.

Also what devices support them? Do the laptop SD ports support them? I read that only certain cameras support them because they need a new interface for those speed classes, which I personally find silly. I know if the device doesn't support UHS-1 it runs at class 10 speeds....why wouldn't it just be capped? It gives the impression that it is like two cards in one lol. (I figured it would be like a SSD hardrive plugged into a slower port like SATA3 drive in a SATAII port but i guess not?)

Thanks for all ur help.

 

Do you have an SD card reader? Why not run CrystalDiskMark for yourself - the card will most definitely be recognized.

You are correct that only certain cameras support them; mine does I believe but tests from other owners of my camera (Panasonic GH2) have shown the UHS-1 cards actually have worse performance than some non-UHS cards regarding sequential write speeds. The UHS cards simply weren't that stable.

Regardless, the UHS cards aren't going to be even close to SSD speeds.

 

I don't have one...I wanted to see if you guys had any here to test because I don't have the money to just drop 100 bucks on a 32g one. As for your comment on the sequential write...you sure the UHS-1 card was not running in class 10 mode? I would like to get one but i am afraid that my laptop wont recognize the UHS-1 speeds and just run at class 10...which would be completely pointless

 

Yeah. Are you thinking about buying the card for a camera or just for storage ... ?

 

well more so as a fast ready boost/use it in camera/use it as USB drive...kinda all of the above ^^

I know my camera wont support UHS-1 but i am not worried more worried about laptop internal SD slot and my usb adapter

 

I would go for a fast class 10 card instead for reliability reasons.

A little background - my camera takes some of the highest-quality 1080p video on the market. I have it hacked to do 176Mbp/s - that's 22-23MB/s. Unless the SD card can write that amount of data indefinitely, the recording fails immediately.
There are only two or three SD cards available today that are capable of sustaining that kind of write performance; one of them is the SanDisk Extreme HD Video cards (Class 10) - the 16GB models specifically. Get one.

The UHS-1 cards may peak at 45MB/s but the models I've seen tested fall into the teens during lengthy sequential writes.

 

alright i guess i'll pass since i dont have the money to spare to take a chance.

 

Buy stuff when you have a defined need for it.

IMO Ready Boost is a waste of time; you're better off investing in more RAM and/or an SSD.

If you want a USB flash drive, then buy a USB flash drive.

If you need an SD card for your camera, then get one.

Right tools for the right job.

P.S. put your computer specs in your sig ... if you ask questions, it helps people answer them based on what you have.
