Silicon Power 64GB Flash Drive Firma ZN F80 USB 2.0 , Gray Aluminium (SP064GBUF2F80V1S)

I ordered the 64 gig version of the Silicon Power Firma ZN flash drive and the similar, but smaller Kingston Data Traveller USB drive. The Silicon Power flash drive is very nice. It fits on my keychain very nicely with a key hole that is perfectly sized to allow wiggle room when using the flash drive with keys still attached. The Kingston flash drive is much smaller, but that makes it hard to handle and it doesn't have any room for your key chain loop to wiggle when you use it still connected. The Silicon Power drive is fast, works great on my Mac and PC as I have it formatted with the factory FAT filesystem. It has held up well for the last three months on my keychain and shows virtually no signs of rubbing against my other keys. I agree with another reviewer who mentioned that the photos make it look like it is curved. It is absolutely flat and actually tapers where the loop is, which makes it fit on a keychain even better. I do find it AMAZING that I am able to carry around 64 gigs of storage on my keychain. Years ago that was a whole stack of hard drives.. many years ago it was unfathomable to have that much space, much less own it for $40. We are the Jetsons! What will my kids have access to???

I recently bought a new vehicle - one in which (for the first time, for me) had an audio system capable of playing music stored on a USB thumb drive. I bought my Silicon Power Firma ZN 64GB USB 2.0 Flash Drive based partly on price and partly on it's simple physical design. Otherwise, it's hard to say why I picked it out of the wide array of other, similar, hight-capacity USB sticks. I suppose, also, that the one negative review of my second-choice as being sluggishly slow to transfer data was another. But, when the product arrived I was totally delighted at it's tiny, tiny, tiny size (an aspect that none of the pictures of on Amazon do justice to). This thing is very small . . . and works perfectly well for what I wanted it for. I stick it in the slot in the dashboard and not much more than the ring shows - yet it holds nearly 640 CDs/albums. That's right, not just 640 tracks . . . 640 whole albums. That is a significant chunk of my entire iTunes collection from my computer. If I buy maybe two or three more I think I will have my entire MP3 library completely contained in the glovebox of my car. I really like the simple, small, and unobtrusive design of this product. The big ring makes it easy to handle and pull in and out of the socket, but isn't an obnoxious distraction sticking out of the dashboard. I was very much unprepared for how small it was, but was delighted when it arrived. I will definitely buy more and recommend them highly.

Had this device for a week now and the functionality is fast and efficient. It comes with backup software which I am experiencing two issues so far. One on win7 LT - when you open the .exe that is initially copied into the drive it resides on and must remain there for use going forward, what is called SP Widget application a visual basic error returns however, it opens each time on this win7 laptop. XP desktop- the .exe file attempts to open and returns error- Widget failed to load. Anyone who is tech-savvy knows this can be related to the PC and/or current settings so I do not weant to put the entire blame on the application. The brighter side is this is optional software which is a nice thing but you surely can manually copy / backup everything easily, efficiently and plenty of 64GB space. Transfer speeds are not bad- will not bore myself and list speeds, etc. It's just good. Very reasonable price. I would lay out 5 stars but for the software glitch may I offer 4.

This product is the winner of multiple awards, and it was quickly evident why. First off, it's small. After years of clunky, chunky flash drives, I was surprised by one measuring less than two inches or so in length. Next, it doesn't require a cap. I've lost more covers to things over my lifetime than I care to consider, so this was a definite plus. Other users on Amazon swear that it is in fact waterproof. I like it too much to test that theory, but I'll take their word for it. The circle on top is easy to thread through a key chain, or in my case, a carabiner. No messing with needle-size openings and embroidery thread here. The same opening makes for a convenient grip when removing from USB ports. As someone who hates dealing with instruction manuals and set-up guides, I was glad to find that all I had to do with this flash drive was plug it into the port, let the driver install itself, and then save away. (Note: an internet connection will be necessary so that your OS can find the drivers for the self-install.) The saving process is incredibly fast, enough so that I could work on my Powerpoint directly from the drive without any noticeable lag time as I (compulsively) saved. One less thing to store on the desktop. The 64 GB storage is also pretty amazing, especially when the price tag is in the neighborhood of thirty-four dollars, plus free shipping if you have Amazon Prime. Not too shabby. Lastly, this drive really is fingerprint- and scratch-proof. I had it in my pocket with keys, and it still looks like new. No fingerprints, either, which is remarkable since I had my grubby paws all over it as I worked on my presentation between flight delays, multiple airports/layovers, and a brief train ride. Color me impressed. All in all, the Silicon Power 64 GB Firma ZN F80 USB 2.0 Flash Drive was absolutely a worthwhile, durable purchase. It gave me one less thing to stress about in the midst of a hellish travel day. Just make sure you keep it attached to something, or it may get lost. alice[unblocked]

I ordered the 64 GB version Pen Drive of the Silicon Power .The Silicon Power Pen drive is very Fast. It is able to write at 20 MB/sec.The Silicon Power drive is fast, works great on My Laptop and PC as I have it formatted with the factory FAT filesystem. I do find it SUPERB that I am able to carry around 64 GB of storage on my POCKET.

Works great but lost a star because the actual available space is 61 GB. Still a good product, works very well and solidly built.

I bought 20 of these as a give-away for a training event I was organizing. When loading the data onto them, one "died" and reported as "write-protected" when trying to reformat. I was in the process of writing to SP to make a warranty claim when I noticed that their web page had a downloadable utility for low level format of their devices. I ran the application and my "dead" drive came back to life. Very happy with the drive, love the design, and the relatively huge loop makes it easy for my fat fingers to insert and remove this tiny bit of metal from a usb port. The only down side I can see is that the small size could make it easier to lose in a pocket.

Appearance is excellent. But damn slow in reading & writing. Hence not user friendly.

The design is unique and practical. Although it is USB 2.0 but I am more than happy with read/write speed. The build and structure is solid. I instruct photography and I am using this device to store all my classes material and it is in my key chain where will stay with me all the time.
