Remote USB Port, 2.0 or 3.0?

Anyone know the speed of the remote USB port that comes with the 2013 models?

not 100% but I would assume its 2.0 since its mainly for mobile devices/iPods.

It's 2.0. USB 3 has a different connector.

that's what I would assume too, but want to find out for sure. getting a new rubi and it'd be great if it was 3.0. pop a big hard drive in there and have my whole music library at my fingertips.

actually, the connector for 3.0 looks the same and is backward compatible with 2 but has additional pins. I don't believe 3.0 would be of any benefit in playing music.

You would not want to use a regular hard drive because of the moving parts...maybe a solid-state drive. I have a tiny $30 thumb drive (literally the size of my thumbnail) plugged into my USB port. It's 32Gb. So far, I have 100 albums (ripped at the least-compressed setting) on there and it is only about 1/3 full. Contents are readable on the 130 display.

I can see USB 3.0 is beneficial only when you have to copy GBs of files to and from the hard drive regularly to save you some minutes.

USB 3.0 can use the same Standard-A connector as in USB 2.0, you might not notice the difference unless you look closely for the additional connection points inside. So far I've seen all motherboards and laptops are using the Standard-A connector for USB 3.0.

Technically USB 2.0 has effectively 280Mbps bandwidth which is way more than most MP3's 320Kbps. USB 2.0 is sufficiently enough for Blu-ray movies. So, I see no difference to have 2.0 or 3.0 port in a vehicle.

BTW, USB 2.0 memory drive does have speed rating, just like memory card for camera. If you found copying files to your USB 2.0 so very slow, very likely it's because your USB memory drive is slow. A fast USB 2.0 memory drive can make 10x or more difference.

This is not necessary true. USB 3.0 is much faster than USB 2.0. Where this will help, especially if you have a large amount of data, is your initial startup time as well as searching for songs in the tree structure and possibly starting a song. The reason your USB stick works so well is because it's flash memory and your head unit can read it very quickly. USB 3.0 would offer a similar ability to quickly read data from a device, even one that isn't all memory

I don't think USB 3.0 will help that.
SSD or memory is fast because it has virtually minimum seek time.
A hard drive is slower because it has significant seek time to move the magnetic head and rotate the platters. Sequential read and write on hard drive can be very fast once the head and platter is in place, but random read and write is where it's slow.
Pure data transfer rate once the drives retrieve the data from its physical material between SSD and hard drive has no difference, it's all about the bus speed. USB 2.0 and USB 3.0 should have no difference in transferring such little amount of data about song information.

So, on USB 3.0 hard drive, you will still be hit hard on the seek time when it has to search and read song information randomly on the disk.

USB 3.0 has a blue connector in the female (internal) connection. They look alike, except 3.0 is blue.

agreed, i was thinking more in terms of a bottleneck with 2.0. Granted, I have no idea how much data is being passed, I was just going by some reviews I read where people were saying they were have long startup times. Could certainly be attributed to the head seeking on the platter. anyway, got my answer, seems like we're still at 2.0 on the jeeps

I also read some of those reviews where people were saying it took forever to read the info from their input device. It could be because they had slow cards in their devices. I don't know what they were using, but my little flash drive starts up in a flash. It says "initializing" for a few seconds...then it says "reading" for a few seconds...then picks up where it left off. Total time may be 6-7 seconds...haven't actually timed it.

One semi-aggravating thing is that you always have to press auxiliary for it to play...even if USB is the last thing you were using. Everytime the stereo or vehicle is turned off, the head unit reverts back to AM...or maybe to the last thing used before USB.

this probably has to do with when you hit the usb button it mounts the usb drive. Probably safer for the data on the drive

How big of a stick have you guys used? I drilled a USB port in the glove of my 07 and want to know how big of a drive I can leave in there for extra music.

That's what I really hate on the stock 130. I think it reverts back to radio because it has to take significant time to remount the drive and read all the music information again. If I hit AUX right after I start the car, it will show something like "not available", and I need to hit it again later. However, I'd rather it takes some time to resume the music when I start the car than I need to press the AUX again.

The software could have first just read the file where it's stopped last time and resume playing from there, and then continue reading other file information at the background or put some cache files in the drive like many camera do in storing thumbnail pictures. Probably they have hired some dumb programmer to do the job.

Might be they want to use that to justify the upgrade to 730N with built in hard drive.

Even the Chinese made MP3 add-on player with USB and SD to stock stereo in my Miata will resume right where I turned off last time in a few seconds after I start the car.

It remounts and starts reading when you turn on the car, but seems like it has to read all music information before it will show as available.

I use this: Cruzer Fit USB Flash Drive by SanDisk

32Gb and $23 from Amazon.

Takes up pretty much zero space.

you can get something like this
Amazon.com: Sandisk MobileMate Micro SD & M2 Reader (SDDR-121, Bulk Package): Computers & Accessories

and add this
Amazon.com: SanDisk Ultra 32 GB MicroSDHC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-032G-AFFP-A): Electronics

the class 10 is the faster reading cards., check your's and you should see a number surrounded by a circle and that should be your class speed. The benefit of using the adapter is next year you can just remove the 32GB and install a 64GB, assuming the radio can read it.

Usually the smaller the stick, the slower it is because they usually uses MLC cells which need fewer physical cells and space and uses less sophisticated controller.

Just some rough figure found here
USB Flash Drive Speed Tests - VID = 781 (SanDisk Corp.), PID = 5571
Sandisk Cruzer Fit: Average read 18Mb/s write 5Mb/s
Sandisk Extreme: Average read 30Mb/s write 25Mb/s

I use a right angle adapter so my usb will flush with the wall rather than stick out, something like this.

So will my music be more uptempo with a faster drive? I wouldn't want the vocalists to sound like they've been snorting helium.

Unless I'm totally missing the point here... Aren't we talking about getting music off of the drive? I, personally have a 16GB Fit... It is GREAT! I would highly recommend it to anyone. That being said, if the average read speed is 18Mb/s and you can't access/play your music, you are definitely doing something wrong. I use my Fit and run video files from my iPhone 5 straight off of it (on the computer) and it does just fine. I actually have one set up as bootable with Ubuntu and run media off of that without so much as a hiccup. For my two cents, the Fit is a great drive and will do well in the Jeep... If I didn't have my iPhone or Sirius, I would have one dedicated with my music on it. When I first got it, I tested it out without any problems at all... Just so we all know...

PS
Drives do have different speeds and this one has enough.

PPS
Here's a look at my fit:

My slow drive must be the reason all my Alvin and the Chipmunk tunes sound like Bill Medley.

I think I want to just keep it in the port in the glove box, with dedicated music the girl doesnt like to hear, and use the hard drive for her...I don't think she knows how to get to the USB source on the mygig. It usually two pushes of the wrong buttons and the usual "I don't get this stupid thing"
