SanDisk SDCZ43-064G-G46 (Flash)

Ultra Fit USB 3.0 64GB

▲ 531,620 ▼

Release date: Q3 2014.

Average Bench: 26.4% (138th of 639)

Based on 12,481 user benchmarks.  Device: VID 0781 PID 5583 Model: SanDisk Ultra Fit

The 64GB SanDisk Ultra Fit is the largest capacity available in the Ultra Fit range. Both the 16GB and 32GB siblings fared well in terms of peak performance but with the majority of flash based products larger capacities are faster. Unfortunately for the Ultra Fit this proved not to be the case. Comparing the performance leading Mushkin Ventura and 64GB Ultra Fit shows that the Ventura is around 600% faster but just 60% more expensive. Although the Ultra Fit is a contender in the 32GB and 16GB capacities it doesn't fare well against the 64GB competition. If you are looking for a tiny form factor the 64GB SanDisk Ultra Fit is superb but otherwise there are better alternatives available with better peak and significantly better sustained transfer speeds. [Oct '14 USBFlashPro]

This USB thumb drive from Sandisk is extremely small compared to most thumb drives. I can store all my work files, encrypt the USB thumb drive for security and have it attached on my key chain and in my pocket. It is not big and bulky at all. Very practical and useful device Sandisk - Excellent work!!! I will be buying bigger sized (i.e. GB) in the same form factor in the future from Sandisk. Keep them coming (i.e. very small USB Thumb Drives) Sandisk!

Well probably one of the densest thumb drive ever. Suggested to buy something that are larger but priced same and offered better performance instead. One Finnish user noted heating issues for this thumb drive. This thumb drive is intended to fit in an ultra compact spaces, are light and small.

Overheats after sustained loads, which hugely slows it down
