Summary: This is third one of these I own. I just got another one for my smart TV. This drive writes at 13MB/s with many files approx 4MB each, and 16Mb/s with a single large file. It reads at 30MB/s. For comparison, 100MB LAN operates at about 11MB/s, and laptops copy files at about 26MB/s, so this drive can keep up with standard usage. Above average performance. I like the slim compact design. I have noticed some delays after writing files for refresh to complete.
Summary: I am buying one or two more of these units, but with or adding a means of keeping them on a lease.
Pros: It makes all the other USB flash drives I own seem like they are running at USB 1.0. I bought it to display pictures and there is no delay in changing to a new 1 - 2 MB image. I can't imagine how fast USB 3.0 would be with drive.
Cons: Case is missing a means to keep the drive with me. I lost it. I did not find a dongle attachment point and had it lose in my pocket.
Summary: This flash drive is still the USB 2.0 technology, which is fine with me. Some people may gripe about that but it clearly states it in the description, and at the current time, there aren't that many computers/products that utilize the technology for USB 3.0 yet. However this product is still quite fast. I have used it for various reasons. I have loaded the installation of Ubuntu on it and burned a copy of Ubuntu 12.10 from this drive to a CD and it performed quite well.
Summary: I purchased this item based on the reviews and the claims of speed. I just got it and quickly did some basic tests copying several files ranging between 40MB to 1.6GB from my hard drive to this pen drive. The pen drive is connected to a powered USB hub, not directly to the computer. The speed indicated by Windows (7 64-bit) while copying goes between 14 and 20 MB/s. I found this speed to be more than acceptable.
Summary: Might make sense for them to attach it to chain or wire. I can see it being very easy to lose, so I took some string and tied to another chain of flash drives I already have so everything is in one place.
Pros: Works as stated, simple plug-n-play. I was able to copy significant movie/music files over with relative speed.
Cons: Drive came with 29.8gigs of space. Not a big issue, but definitely not 32gig.
Summary: I use a thumb drive to replace what I once used a portable hard drive to do - mainly backup important files frequently and keep them with me wherever I go. You never know when you might stagger into a library and need to take a quick listen to your latest pirated music collection! So far, this drive has plenty of space left for files but I do notice that smaller files take longer to access compared to my previous drive (a 4GB Transcend).
