Transfer rate is "Up to 150MB/s" which technically is not wrong. and the READ speed as shown in my CrystalDiskMark holds true.
The WRITE speed... is Slower then a decent USB 2.0 drives.
I'm keeping it just for the read speed and space.
It is extremely inaccurate its maximum speed achieved on usb 3 is 18 MB/s. Read speed is 140MB/s.
I tested today on USB 2. At the beginning copy speed is 18MB/s and after some time it drops to jawdropping 2.3KB/sec!!!
People stay away from this flash drive.
I use the SanDisk Ultra 128 to transfer photos from an Android smartphone to a Windows 10 PC.
Of course, I can transfer photos via Bluetooth (although slowly), and I can connect the smartphone directly to the PC via a USB cable. But, the convenience factor of this product is, I don't have to be tethered to a PC in the event a call comes in, and I need to be away from the PC during the call. I can still take the call, freely walk away from my desk and backup my photos at the same time.
The only caveat is . . . its tiny form factor has somewhat of a tradeoff. That is . . . because this thing is so tiny -- it can be easily lost or misplaced (at least for me when I am not focussed).
This flash drive is amazing. I was able to "move" and/or "copy" dozens of files from my fone's internal storage as well as it's additional external storage chip. One copy/transfer was 3700 images/videos and took less than 8 minutes to complete (phone to Sandisk).
The only "issue" I have with the SanDisk Ultra 128GB Dual Drive is that the "ports" are exposed to the elements. I would have left a 5 star rating, but it needs some sort of dust cover or caps for the plug ends, as I plan to keep one on my keychain, and there is no protection for dust, dirt, or pocket lint!. Maybe someone makes something for it, I hope.
