Average Bench: 25.8% (138th of 639)

Based on 4,492 user benchmarks.  Device: VID 0781 PID 5583 Models: SanDisk Ultra, SanDisk Ultra Fit

The 32GB Sandisk Ultra Fit has both a tiny form factor and a respectable performance profile. With peak sequential read/write speeds of 136/55 MBps and peak 4K read/writes of 6.6/2.0 MBps the 32GB Ultra Fit sits amongst the top 25% of 32GB flash drives. In terms of value for money the Ultra fit fares even better and is bested only by the Sandisk Extreme. Comparing the 32GB Extreme and Ultra Fit shows that the Extreme has over double the effective speed yet the extreme is only 32% more expensive than the Ultra Fit. To conclude, the 32GB Ultra Fit has good peak performance (sustained performance is far less impressive) but its key strengths are its tiny form factor and reasonable price tag. [Oct '14 USBFlashPro]

USB Flash Drive Rankings (Price vs Performance) December 2018 USB Rankings.

We highlight the best USB flash drive in terms of balanced performance and value for money using current prices, sequential read, sequential write , 4k read and 4k write speed. The speeds are combined to form a single effective speed which measures performance for tasks such as copying photos, music and videos. Effective speed is adjusted by current price and capacity to yield value for money. Finally thousands of individual user ratings are used to validate our benchmark figures. [USBFlashPro]

Ultra-small and low profile drive...

Yeah, so this thumb drive looks like it gets throttled after about half a second of writes (down to ~20MBPs), presumably so that it does not actually melt your computer (it gets quite hot). In short bursts, it is very fast, perfect for holding an OS, which is what I use it for, hence the high rating. Not the drive for moving lots of data around.—Jan '16

I like it, but it gets hot after a few minutes (even if that doesn't matter)

I bought this pen drive after watching it's write speed of 80+ MBps on this website and it turns out that it doesn't provide write speed of more than 20 MBps even on USB 3.0. This website is not very trust-able.

I have two of these and both frequently disconnect in the middle of use (every 10 seconds)

Heats up and write speed drops dramatically

Lightning fast Read. But write speed seems to throttle after a few seconds and goes down to around 20 MB/s


Above average

I just have no idea why they build a such fast pd that is capable of 90 mbps write speed in a such small form factor that it gets throtled after 5 seconds and drops down to 20 mbps. Why didnt they build a nice little heatsink on it, or a metal case that can dissapate the heat? It's a pitty. However the 140 mbps read speed is still freaking amazing :)
