I have read 104.2 degrees F on this unit. It moves any sizeable amount of data and it gets very hot and the write speed slows to a crawl, as does anything computer related when it overheats. Not impressed. Caught on sale and used best buy points on this, paid $7 and still feel like I overpaid. Can't recommend this at all.

Great item for saving all your important files in on the go

Fast flash drive with easy to use support for usb c. Great overall product. Will be purchasing more.

Works good. As expected. Ordered this to store pictures.

Good value for price, and use to backup on my laptop.

love the product was able to move documents from computer to cell phone. excellent product

It’s ok, I would not recommend if you’re transferring 6 plus gigs of information.. takes a long time

Do not buy overheats way to easily and i would not recommend either

Very nice thumb drive thas is handy to carry around with dual connections.

Easy to transfer, smooth to work with. Perfect for on the go work flow.

Worth the price easy to carry and connect to mobile as well great one

This Sandisk flashdrive packs a lot of storage space into a tiny package. It's only slightly bigger than the two connectors; one usb c and a regular usb making it more versatile. Nice metal case with a swiveling cover and loop for keyring or lanyard. It's pretty small so try not to lose it. I transferred about 14 G of music files to test it out. It's write speed started out pretty fast at about 50+MB/sec but after a few minutes slowed down to around 15 MB/sec. This is pretty normal for large file transfers to a flashdrive but likely will be fast for a smaller transfer. I then transferred them back to my hard drive to test the read speed and was pleasantly surprised as it showed consistent 140+MB/sec and was done in just a few minutes. Very fast! If somebody told me a few years ago that you could get 512 GB (490 free) in such a small device and this fast I would have had a hard time believing them (maybe not). I've used many Sandisk storage devices and all have proven reliable. Great brand! It does get kind of warm when using it but the metal housing should act as a heatsink so it hasn't been a problem for me.

Good USB c drive for storage and archive retrieval.

I didn't like that it didn't have instructions on transferring files back and forth.

I thought it would work with my iPhone but it is not the correct one

I'm using this with a 2019 MacBook Pro, using After Effects. It FAILS OUT if I try to write outputs directly to the drive. This is the whole reason I bought it and I'm annoyed. I never had this problem with USB drives. I don't know if it's a compatibility problem or a MacBook pro problem.

This flash drive became so hot that I was afraid it would damage my PC. Don’t buy it.

The SanDisk Ultra Dual Drive Luxe 512GB USB 3.1, USB Type-C Flash Drive is a well thought out device housed in a metal case. The dual USB device can be accessed using either the USB Type A or USB Type C connectors which are located on either end of the device. The USB-C connector allows access to Android devices that connect using Type C USB which allows offloading of photos, music, etc. saving space on Android smartphones. The 512GB capacity and metal outer cover should provide years of storage use at a reasonable price. This device is well designed, easy to use, and built to last.

SanDisk - Ultra Dual Drive Luxe 512GB USB 3.1, USB Type-C Flash Drive - Silver This 512GB Dual USB drive is the latest generation of the dual drives from a year ago. It supports a slightly faster interface and is small in size, all metal, larger capacity, but has no closed (capped) position. When testing I used my main PC that supports the latest USB standards as well as my Android phone. I used 2 programs. 1st was Crystal Benchmark, the 2nd was USB Flash Benchmark. The read speeds are stated as up to 150MB/s. I got 154.88MB/s on SEQ1M Q8T1 setting, with 114.36 on SEQ128K Q32T1. The write speeds were considerably slower, but they always are. My test shows 35.75MB/s SEQ1M Q8T1 and 40.73 SEQ128K Q32T1. When inserted it comes up as a USB 3.2 drive. I tested it against last years Dual drive that was USB 3.0. It was no faster in the Sequential reads and writes. However, the new drive did obtain 2.5 time faster Random Reads and about 2 times faster random writes. So, all in all it is a slight improvement from last years device. The real jump comes in capacity. Last year the largest drive I was able to get my hands on was 128GB. I was just unable to get anything larger for whatever reason. With the 2nd program I could see that the speed of the drive drops off at around 256KB in file size. With larger files it toped off at 158.9 MB/s read and 69.8MB/s write. Smaller files took much longer, as normal to any drive trying to handle them. I am very happy with this new larger capacity being available. The price will start to drop as more and more factories come online. A thing to note, the all metal case gets very hot when being pushed to write. Reading does not seem to get overly hot, but writing is above normal. This could just be because of the metal case is transmitting more of the heat outside, as a way to cool the flash chip. Larger capacity means longer writes, and they have to get rid of the heat somehow. The bottom line for me is this is a great drive. It’s slightly faster than any other drive I have and is 4 times larger in capacity while being smaller to have on your key chain. My only negative is I wish it had a closed position, but hey, that’s just me. Oh, and one other thing. I almost had to use a chain saw to get it out of the packaging. I cut at the line, then lower, then lower, then got my razor knife and started in on the plastic around the drive.

Love SanDisk products. Needed to free up memory from my Droid. This always does the trick.
