Bests & Worsts Reviews from Amazon

I own both this flash drive and the Kingston DTSE9, which is very similar (capless, all-metal design). Both are great drives. I think this drive may have a slight advantage in long-term durability, since supposedly the DTSE9 suffers from a problem where the metal casing separates from the innards of the drive (though this hasn't happened to mine). In terms of putting the drive on a keyring, this is definitely the superior drive... the thinner loop works much better on a key ring. However, the flare of the loop may obstruct USB ports that are located side-by-side (ie the ports on many laptops). The DTSE9 does not obstruct other ports. Both drives are pretty good-looking, but this drive wins out because the Kingston has a dissimilar metal that lines its loop, making the inside of the loop look jagged. As far as fit goes, my DTSE9 is better... it fits perfectly in all USB ports I have tried. This Silicon Power drive is always very snug in the USB port.. sometimes so tight as to be concerning. There are two reasons that I ultimately like this drive better than the Kingston. First, this drive is waterproof. A lot of flash drives will survive water, but I like that this drive explicitly states that it is waterproof. The other reason is heat. My DTSE9 gets very hot, while this drive hardly gets warm. I don't think the heat is really damaging (silicon can get pretty hot before it is damaged) but I still prefer to have a cool drive. EDIT: failed catastrophically after one year of light-medium use. I am pretty disappointed considering I have had generic "freebie" flash drives that lasted longer... I noticed something was wrong when the drive started to have a very noticeable "seek time" when browsing for and opening files. I feared the worst and tried to copy my files off of the drive. The copy errored out. I used Unstoppable Copier to get as much as possible off of the drive. Some stuff recovered okay but most of the photos were corrupt and wouldn't open or had large color bars across the image. Tried reformatting a couple different ways including with Diskpart, but always received I/O errors. Meanwhile, the four DTSE9 drives that I carry daily have not given me any problems, and they get used/abused much more than this drive ever did. Don't think I will trust Silicon Power with my files again.
