Conclusion 
Average Bench 26.4%

We really like this drive, it's one of our favourites. The JetFlash 780 has superb benchmark scores, at 170 MB/s this drive has the highest sequential read score we have ever seen on a consumer grade flash drive. Very interestingly the performance profile on our test unit exceeded even the manufacturers claimed speeds by over 30MB/s! The 4K write speed is less impressive, but passable at 0.3 MB/s. With reasonably solid all round performance and a reasonable price point of £23 this drive represents outstanding value for money. [Jun '12 USBFlashPro]

MORE DETAILS

We like this drive, it has the highest sequential read speed we have seen to date and the remainder of its performance profile is also respectable. At 198 MB/s the read speed is almost double the speed stated on the drives box, and 33% higher than the speed quoted on Lacies website, an unusual result that needs verification (comments from owners welcome). In terms of form factor we are very disappointed with the oversized orange cap and can't realistically see anyone leaving it attached to the drive. Without the cap this drive is superbly strong, ultra compact and performs respectably, we like it a lot. The only problems we do have with the Lacie RuggedKey are its price which is simply not competitive at this time and we would have liked to have seen higher random 4k speeds for this top end drive. [Aug '12 USBFlashPro]

ALL FAQs »

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
