[Q] USB OTG is there a difference between a flash drive and a micro sdxc? - Nexus 10 Q&A, Help & Troubleshooting

When I mean difference I am talking about performance, battery usage, video play back etc. Also what do you prefer so it can help me make my choice between a 64gb USB Stick or a Micro SDXC.

usb speed

Hey guys,
i just got an 8gb sd card for my xda star. when i used it with the shipped card reader i was very pleased to achieve about 20mb/s
now that i have it in my phone it's only about 1mb/s maybe even less.
how fast does your usb interface work?
1mb/s=10Mbits
10Mbits=USB1.1
It's normal speed for phone without usb2.0
ok,
the specs say, it's a usb 2.0 link so i expected more
My card is Sandisk 1GB, but it slow too...

External SD Capability/Support

Like the title says, does the Nexus 7 support external sd? I think it does, but I want to be sure before spending $50 more for 8GB, when I can go and buy 16GB micro SD card for $15-$17. So yeah, does the Nexus 7 support external SD cards (micro or regular)?
It hasn't micro sd card slot!!
** and no memory card slot expansion at all!!
The lack of SD slot really annoys me (the damn Raspberry Pi has one, FFS), but after some him-hawing around, I decided to get it. I just wish my ISP was not so sucky. I imagine I will do lots of reading and gaming on it, mainly.
Despite the lack of microSD, it is a nice piece of kit.
it may support usb otg but the micro usb port needs to be at 5v not 3.3v. no one has confirmed this officially but if it has the requirements then you can use a flash drive with an adapter. asus's other devices have supported it so hopefully this will too.
Not having external SD support is only a minor inconvenience but this device is still worth buying.

Help of flash drive

Hi,
I need some advice here.
I was about to back the kickstarter project for the mini microsd card reader http://www.kickstarter.com/projects...-smartphones-and-ta/posts/458396?ref=activity
However, I saw a usb drive that has a micro usb slot. http://list.qoo10.sg/item/UNUS-SMART-X-OTG-USB-FLASH-MEMORY-4GB/409872086?banner_no=3053
I am intending to use it to store games on it.
I tried using the long otg cable with my sd card to store games previously but i found that there is a certain lag to it.
Do you guys think getting the usb drive will speed up the perfomance? or will the mini microsd card be better?

Not necessarily. It's probably the class rating of the SD card. I would first try to verify what the speed class rating is of your microSD card. If it does seem to be substantial, then you might pursue one of those devices. I'm willing to bet that you just need a faster card.

Dual USB Stick for OP5

Hey guys,
since Thema OP5 is using USB C I can't use my micro USB to USB A dual stick anymore. Is there a dual USB with a USB C Port to use it with the OP5 that you'd recommend.
From what I've read, the sandisk ones are overheating easily and therefore drop massively in writing speed.
Thanks in advance.
Do you mean one of these?
Look at this on eBay http://www.ebay.co.uk/itm/182584294759

If Samsung S10+ has max SD Card size 512GB, can I use USB OTG hub with 1tb card?

Hello,
The title is pretty self explanatory. I have a Samsung S10+ that is constrained to a maximum internal SD Card size of 512GB.
I wonder if I can use a USB Type-C OTG hub along with a 1tb SD card? Or will the phone fail to cooperate with the full 1tb external storage.
Thank you.

There's not really a simple answer for this. Generally, Android can support storage far into the terabit range, so SDcard size limits are generally dictated by artificial limits in the software. An external SDcard and USB OTG are both considered removeable storage, so limits that apply to one will likely apply to the other.
However...
OEMs tend to fib a lot when it comes to supported SDcard sizes. My T290 supposedly only supports up to 128GB but I've used a 512GB in it with no issues. They do this so that you'll buy a higher priced device, and sometimes implement artificial limits as described above.
I'd say just try it. Get a 1TB card on Amazon, and if it doesn't work, return it. If it does, make sure you let the S10 community know what you were able to "get away with".
Wow, amazing response thank you. I have ordered the 1TB SD card and will let you know how it goes. Hoping it will work just by slotting it in, without the need for the USB OTG hub.
It probably won't be able to use or address the full memory if used in the SD card slot. Not sure how it will respond with a OTG porting?
A OTG hook in will be substantially slower than using a V30 rated SD card in the SD card slot.
I won't buy anything slower than V30 rated SD cards because of this.
SDXC is *technically* limited to 2TB. The maximum sizes often reported in specs is the card size it is certified (ie tested) with. There can be bugs for larger sizes sometimes. That being said, I can mount my 1TB card in el $150 chinese tablets that say they can mount 64GB cards... so I don't see the reason it wouldn't work on your S10+ in particular...
While you can use USB OTG with Paragon ASF, its just too much of a flimsy thing compared to plain SD card.
