Product reviewsSanDisk Extreme PRO USB 3.1 Solid State Flash Drive - 128GB SDCZ880-128G-G46

Fastest usb flash I have tested

Fastest usb flash I have tested. It's at least 4x as fast as Samsung Fit Plus 256GB in write speed. But compared to my past gen Extreme 64GB (not Extreme Pro) it's about 10-15% faster in transferring large files, but for small files the difference is just a few %. Flash drives were connected to USB3.0 ports, maybe the difference would be bigger if connected in 3.1 but I doubt it, since while transfering large files Extreme Pro has spikes of 340MB/s but 99% of the time the speeds are ~200-240MB/s. I also noticed that sliding mechanism is better on my previous gen Sandisk drive. This one has smaller notch which your finger has to grab to slide the mechanism, cause the rest of the surface is very slippery.
Would I recommend this drive. Yes I would.
But if you want the fast drive with better value I would suggest going with Extreme Go which is ~30% cheaper. If it is fast as it's previous model (Extreme USB 3.0) that is best buy.Read full review...

Highest speed if set up correctly

At first I thought it was lacking the advertised speeds - but this is because you need to disable quick eject (in windows - haven't tried it on any other o/s) - which enables write caching and allows the full speeds to be obtained (less than half without - c. 120MB/sec write speed - if quick eject enabled.) So very pleased as I bought it for high speed transfers - and it does that. Other than that its just a normal well designed usb stick - don't know about reliability yet, but can't imagine it won't be reliable.Read full review...

Great portable memory from Sandisk

I always use Sandisk Pro SD, microSD and Pro USB pen keys. I use them in mobile phones, cameras and with my computer and TV. They perform brilliantly. I can typically copy from my laptop onto an Extreme Pro USB at 220Mbps! Great for such a small device.
Highly recommended.Read full review...

ASTONISHING DATA TRANSFER SPEEDS

I bought this after being seriously disappointed with read and write speeds on virtually everything else. I tended to opt for a cheap high volume alternative with sticks and cards but these days I do a fair amount of exchanging project footage/audio in one go onto someone else's laptop or system. And it's embarrassing when it starts reasonably fast then slows to 2mb/s and you may as well put the kettle on.

All that changed with this beauty. Considering I'm using a 6 year Thinkpad, I never thought I'd see speeds in excess of 300mb/s on data transfer. Without even using the USB3 ports on the docking station.

The next stick I buy will probably be the 256GB one.

Couldn't recommend it more highlyRead full review...

superfast but expensive

pro:
- Incredible fast both to write and read
- perfect choice for a Raspberry Pi 4 b+

contra
- a bit bulky, not too easy to plug anything next to it to the other 3.1 USB port
- quite expensive for a low-priced computerRead full review...

Robust, Reliable and fast memory sticks.

Had various SanDisk memory products over the years, they've always been robust, reliable and fast (as much as the technology allows at the time) - these new memory sticks are no exception.

Worth spending the money

I use this to record live mixes on a Pioneer XDJ-XZ as previous USBs didn't have the write speed. Does the job perfectly...so far! :•)
