That all depends on what you considerers constitutes "decent".

I agree snuke. So far the iPod Nano has left the USB thumb drive in the diet for speed.

I've just looked through the manual (yes, a rare thing) hoping to find the specs for the USB ports. I assume they are only USB2. It would have been nice if they were USB3.

I'm going to take another crack at loading up an SD Card and testing the speed. The one I used ws a 32GB (6) and I think I have a 32GB (10) which "should" be much faster. The manual does make one statement I find hard to believe. It says when you first connect a device it takes about 5 minutes for every 1000 songs to get set up and "browse" can't be used while that process is under way. For 6400 songs it was much less than 5 minutes.

My preference for the SD card is due to the fact that a USB drive will stick out whereas the SD card is virtually hidden. To me the advantage is security and that beats leaving an iPod in the car.

In my Town & Country I loaded about 400 songs on the internal HD when I got it so I could test it. It worked reasonably well but I've wondered what it would be like with 6000 songs. I never really continued because for the last 7 years we've found we enjoy SiriusXM on long trips. Recently it come home to us just how much music we have in our iTunes library. My Dear Wife (DW in RV lingo) asked me why I have not sold all the CDs stored in several large bins. There are over 700 of them. I had to educate her in the ways of BMI and ASCAP and the fact that since we loaded all of them into our iTunes library we have to keep them as ownership is required to comply with the law. I recently had other reasons to study the BMI and ASCAP operations in the US and I've concluded that I certainly don't want to have a run in with them - they rarely lose in court.

We only have perhaps 200 or so songs purchased on iTunes - mainly because we have so many to listen to already and we can't even scratch the surface. Anything I want I do buy on iTunes (some damn good deals in the jazz area) but DW continues to buy a lot of CDs in the jewel cases at garage sales. She has a dozen now she wants me to add to the library and put on either the USB drive or SD drive so she can listen to them in her Cherokee. I think she now understands why we have to keep these large bins.

whoops, "diet" should be "dust" but after what I consumed today "diet" might be a good idea.

I have been a professional electronics engineer for 30 years, so by decent I mean fast and reliable from a well respected manufacturer. Thumb drives are commodity now, there's nothing to them, just a couple of chips and a housing. So even the cheap ones work well. We give them away as promotional items, 4GB are the smallest we can get and they cost us a couple of bucks each with the company name and URL printed on in 500 off quantities. To provide context, we make 64TB flash storage arrays. If you are in the server business, they take 3U of space (less than a hand width vertically) and contain two fast servers as well as the flash subsystems. We manufacture from scratch in local factories using parts sourced in the far east. We don't used SSDs or SD cards, all the boards are our own design. One of my responsibilities is the USB interfaces we use to permit local software updates for systems not connected to the Internet, so I've done a lot of USB testing and have a great many USB keys lying around. Well you did ask. I am pretty sure I know a decent USB key.

PNY Attach 3 128GB $52.97 from Amazon. 4 stars from 267 reviews. Usually if something scores 4 or above then the majority of the negative reviews are bone heads and bad luck. I signed up for Prime so it might be here on Friday with free two day shipping. I buy a lot of electronics. Amazon deals with failed hardware well, but in 15 years of shopping from them I have only needed to return two items. Better still use a local vendor who will price match, then you are keeping at least a few pennies in your community.

The only problem might be the length of that drive, but you can get good small 64GB USB keys for relatively little. Or how about a Sandisk Professional 128GB SD card for $74? Over 4/5 from 1101 reviews. We tested them to death and they should last years from what we saw. SD cards work faster and last longer if you leave a lot of free space, but for this application bandwidth requirements are trivial.

Anything else you'd like to know?

Yes USB 2 only, and the other reasons you listed are also why i went SD.
The class system is broken, and there are a multitude of speeds for class 10.

I got this Sony 64GB SD XC card because if it quick read and write speeds.



The read times from Uconnect don't seem to make a huge difference, but it was there. The few minutes I saved copying the files across however was very noticeable.

Work well they may do, but it hurts my brain having to wait for files to copy, so a fast as well as a reliable stick is important to me. And even that is not as simple as USB 2 vs USB 3.
I purchased a couple of cheapish but reliable USB 3 sticks, and they were 1/3 the speed of my good quality Patriot USB 2 stick.

The quicker the media can be read or written is important to me.

USB1 was rated at 12Mb/s, USB2 is 480MB/s, USB 3 is 5GB/s but most devices can't do anything like that. The highest rate needed for music is 320kbps, but finding what's there is the hard part. Accessing the system is much the same on USB2 or 3 because the drive or iPod can't use the full bandwidth. USB3 would be always on, at 2A you might not like what happens if you leave your iThing plugged in for a couple of days.

The problem with uConnect is the slow processor in the head unit. Reading a few dozen directories takes it several seconds. That is an age for even a cheap modern processor. These systems are much slower to start and run than competitive systems. Browsing is much slower on these than some of the others (I rent often, so I have used Ford, Infiniti, BMW and various others recently). A good example is entering a word in the navigation, on a current BMW it searches as you type and can keep up, on the current uConnect it took several seconds for each letter after the first. Browsing the iPod was faster in the Alpine head unit in my 2003 VW. Sad to put a slow system in a $50k+ SUV which is otherwise great.

Yes, you have to buy decent ones. I wouldn't consider the cheapest ones.

PNY Turbo 3 128GB drives claim up to 130MB/s write speeds. But I'd be very surprised if they could achieve that in the long term. If you try to fill it I bet it would drop to a quarter of that by the end. $80 according to their web site.

Shop carefully. Merry Christmas.

What firmware are you on?
This got fixed two releases back, mine has been instant since day one, but it is only a month old so had new faster firmware from the get go.
Many mentioned it had a big increase in speed / drop in lag.

Re: Music people: uConnect confusion- help plz

I put the 6400+ songs on a PNY 32GB SD card class 10, 20MB/s read speed last night. Tried it this morning. Too darn slow. DW will not really use anything this slow. I'm going to have to look at an 80MB/s theoretical read speed card when we get back to Florida in a couple of weeks.

The cards I have now are 2 to 5 years old and are not really adequate for my cameras so I'm going to have to purchase more than one anyway.

Any suggestions?

..... just went back out (even cool in the garage in this weather) and put the USB drive back in. Takes a bit of time to start up the first time but after it is up it is much faster than the SD Card. I put it in the port in the armrest/glove box to keep it out of site and hopefully it won't get pulled out accidentally.

If she finds it acceptable I won't bother getting an SD card for her.

Re: Music people: uConnect confusion- help plz

According to UConnect, SDXC wont work in the 8.4 because of the exFAT file system used. Interesting to see some reports here of it working.

See my earlier post Sony 64GB SD XC card working well- Music people: uConnect confusion- help plz

I just ran Black Magic Speedtest on it and here are the results, as usual, not close to the claimed max speed, but lower than I expected.
It loads quickly in the car. I was using FAT32, it will be interesting to see if I notice it load quicker now that I have just switched it to NTFS.
It shouldn't, as the read difference is only 3.9%

FAT32



NTFS
