Silicon Power Jewel J80 USB 3.1 Gen 1 Flash Drive 64GB

I purchased 7 of these USB 3.0 Flash Drives. I was expecting higher 3.0 Write speeds, but I'll end up keeping these. Drive #1 ----------------------------- Test finished without errors.

I really like the design of this USB drive. It feels very slick and polished. I like the capless design and the ring on the end. I threw it on my key chain and it looks great and is not clunky feeling.The design tapers out at the ring a bit, but I don't think the ring is any wider than a standard USB flash drive. You shouldn't have any issues with it bumping next to another connected USB device. After connecting it to a USB 3.0 port on my desktop computer, I opened and ran CrystalDiskMark. I have recorded the results below. CrystalDiskMark Bench Test: Sequential Read: 167.MB/s Sequential Write: 21.15 MB/s 512K Read: 155.7 MB/s 512K Write: 1.165 MB/s 4K Read: 11.32 MB/s 4K Write: 0.025 MB/s 4K QD32 Read: 12.20 MB/s 4K QD32 Write: 0.028 MB/s I felt that the sequential ... MoreI really like the design of this USB drive.

I changed USB ports and ran the test again. I won't post the next findings but I will mention the average (out of 5 tests) sequential write speed was even lower at 20.62 MB/s. Benchmarks may not mean a lot to some users, but I was expecting no lower than 40 MB/s write speeds. I had a very similar experience when testing the Silicon Power 32GB Blaze B05 USB 3.0 Flash Drive. The drive does read faster by about 30 MB/s though and is faster overall. I figured, I'd give it one more shot with a real life test and copied a 3.81 GB ISO image to the drive via SATA III to USB3.0 speeds. It wrote at 22.4 MB/s at it's highest and dropped as low as 16.6 MB/s. It took about 2 minutes and 30 seconds for the transfer. I ran a quick format to NTFS and tried the file transfer again. Results were the same with the highest cap at 22.2 MB/s and the lowest at 16.6 MB/s. Again, the transfer took about 2 and a half minutes to complete. The drive is formatted as Fat32 by default, but you'll probably want to change it to NTSF or exFAT for larger files. It also comes with recovery software pre-loaded. Overall, this is a standard USB drive that will be just fine for most users. If you are looking for a super fast write speed, this won't get you there. However, if you want a sleek drive that you can throw on a backpack or key ring to hold files for class, this is your drive for the price.

The metal housing of this flash drive is quite nice; it provides for a durable design that is easy to attach to a key-chain and the loop makes it much easier to pull out of a USB port. Metal conducts heat much better than plastic so this drive does get notably warm to the touch when in use, but this is a common trait of metal housed flash drives. I would have liked to see an activity light and some sort of cap (which would be immediately lost) to keep pocket lint out of the connector, but aside from these two complaints I cannot fault the design. The flash drive was detected immediately by every computer I tried it in and the speeds are pretty solid for a budget minded drive. My drive arrived formatted in FAT32 with exactly 60 GB of free space.

The flash drive was detected immediately by every computer I tried it in and the speeds are pretty solid for a budget minded drive. My drive arrived formatted in FAT32 with exactly 60 GB of free space. CrystalDiskMark benchmarked the drive with a sequential read of 132 MB/s and a sequential write of 51 MB/s; transferring a video file yielded speeds of about 120 MB/s read and 40 MB/s write. There are flash drives that are much faster than this, but they are much more expensive. I don't have the equipment to properly test the shockproof claim, but the drive did survive several minutes of use as a cat toy on a tile floor. I was, however, able to test the waterproof claim. I put the drive in a glass of water for just shy of 23 hours and after about 10 minutes of drying, it continued to work perfectly fine. I also stress tested the drive with over 70 passes of writing and wiping the drive and it has yet to have a single problem. Plus, if something does go wrong with the internals of the drive, Silicon Power offers a lifetime warranty. Overall, I like this flash drive. The metal housing is robust while remaining compact, the fact that it is waterproof further adds to the peace of mind, and the speeds are nothing to complain about. Couple that with the low price and the lifetime warranty, and I would definitely recommend this flash drive.
