Silicon power is probably one of the best companies for product registration and warranty support. On the flash drive is an exe that will direct you to a web page to submit your name and email. Its really that simple.
The Silicon Power USB 3.0 J80 Jewel flash Drive is definitely a very durable but fashionable device, being made of Zinc Alloy with a Titanium finish. Like the SP J07 Jewel Flash Drive, this is waterproof, dust proof, shock proof, and vibration proof. I like that this uses a true cap-less design, making it very easy to use without fearing a design flaw will obstruct usage.
I first tested the claim with this product being waterproof. I placed the flash drive in a 10 foot bucket of old water for roughly an hour, and sure enough, the drive worked perfectly after being plugged into my computer. On first glance the drive is officially 28.8GB. I then performed a test using CrystalDiskMark, a benchmarking program for testing the speed of the flash drive. This test results are from the average of 5 tests of 1000MB. I’m unsure of the speeds this drive will achieve because there aren’t any claims on the website or packaging.
Read: 39.24 MB/s
Write: 10.22 MB/s
The write speed of 10.22 MB/s is abysmal for a US 3.0 drive. These are speeds you’d see for USB 2.0, not USB 3.0.
▶ Final Thoughts
I like the build of the drive but not the performance. I can’t give a good rating to a flash drive that gets USB 2.0 speeds, which is why this gets a 3 star rating. Buy this product only if you need the durability aspect.
+ Very unique but sturdy design.
+ Waterproof, dust proof, shock proof, vibration proof
+ Uses true cap-less design.
- Flash drive speeds were very slow for a USB 3.0 device
