SanDisk Ultra CZ48 32GB vs SanDisk Ultra Dual Drive

0 port. Sustained read speed is about 38MB/s which is close to the limit of USB2.0. Burst write speed is about 22MB/s for about the first 1GB, then the sustained speed drops to about 17MB/s

SanDisk Ultra Dual Drive Luxe:. - Decent reads at 150 MB/s and writes at 50-60ish MB/s.

Great thumb drives and 3.0. Love the retractable port ends. No frills, does what I bought it for; very pleased

I got this because I don't like having to buy adapters and carry too many things with me and I just needed portable storage that could work on Windows, mac and iPad. USB-C is the way only convenient way I could actually do that, but my college still uses desktops with USB ports so I needed both, this is BOTH. Hopefully it's durable, the brand is reliable so I'm guessing it will be, I also got this on a pretty good deal considering the regular price. - Works on Macbook air - iPad air - Windows Kind of wish iPhones came with USB-C but airdrop works for me

I have only used this a couple days now but it seems to be everything it is advertised as.

I teach in multiple classrooms, and hence I go through a lot of USB flash drives, and typically replace my primary one once a year. My new laptop had only USB-C ports while many of the other computers I need to use only have USB-A, so I thought this flash drive would be perfect. (There are not many alternatives with dual connectors either.) In this regard, it did what it was supposed to do

However, they have provided security software on this stick that is very poorly written and even dangerous to use. It is entirely possible for that software to delete the ORIGINAL FILES on your hard drive that you are trying to back up on the stick. I have sometimes saved the situation by pulling the stick out when I get the erroneous message, but once the program succeeded in deleting the source folder on my hard drive. If you don't use their security software, this is a fine product

Also same price on B&H:

You also got to remember it is san disk, it is a trustworthy brand and over the years they have become more durable (remember during the usb 2.0 flash drive days san disk drives use to break quite often). It definitely a good drive.

While I appreciate the dual end design and I will continue to use this drive as long as it lasts (I'm sure the heat will eventually destroy it), this USB drive needs a longer Type C end so that it can be used with thicker phone cases.
