SanDisk 64GB Ultra Dual USB Drive 3.0 - SDDD2-064G-GAM46

This flash drive is just exactly what I was looking for as I needed to find a high quality OTG and Micro USB Flash drive that works well and fits onto my keychain for travel. This SanDisk 32GB is high quality like other SanDisk Flash drives I have owned before and better.PROS:1) I added a THIN and SMALL ORING (Keyring) and to that I added a small hook (I bought it at a local store). Then I was able to place this onto my Keychain. (See below pictures). I easily slid my thin ORing Keyring onto the the SanDisk Flash drive and it did not interfear with the sliding of the unit at all and it looks great on my keychain without taking up much room. Be sure to take a look at my several pictures to see what I mean.2) It is very small and it is just what I needed as it takes up little space.3) There are no CAPS to lose. I am always losing caps and I like that SanDisk places a slider that slides from the center in which to let out either the Micro USB plug or the Standard USB plug.***Be sure that when you push the center lever that you hear a CLICK sound, this fully extends the plug out (either the Full USB one or the Micro one).***Be sure that you push this firmly to fully unlock the whole USB plug. This is why SanDisk placed the CLICK sound so it will LOCK OUT to the outside and not slide back in.4) The speed is good both transferring data to or from my phone or tablet to my PC. Just about the same as regular USB SanDisk Flash Drive.5) The most important thing is that when I fully extend the Micro plug and plug it into my Samsung J7 that has a cover on it, I do not have to remove the cover like I do on other USB Flash drives.6) This I tested very well on 4 devices: 2 Tablets, my J7 Phone and on a friends phone. It worked perfectly in every device that I tested. In seconds the devices recognized it and read the files, copied the files etc.7) The standard USB Plug easily fit into my picky desktop computer USB port and also into my laptop port with ease! It is plug and play and both computers read it in no time.8) There is some files on the flash drive as you will see in the picture that I took. SanDisk has a handy PDF File on it with helpful info about backing up. So helpful.I am so happy with this, I plan on ordering more. This is just a wonderful and useful flash drive that I can travel with and keep on my keychain.Highly recommended!

I have to have my USB drive hooked to my car key - that way I can't leave without it =) Only problem is they oriented the large USB end such that when installed in a vertical port (Dell minitower), the keychain loop is on top (upside-down). It should be the other way so my key hangs down below instead of awkwardly off the side (grrr). Minor annoyance, I'll get over it.I loved the old Cruzer titanium with the retractable connector. New Cruzer drives are slow and bulky, though. The tab style is nice and tiny but either comes with a cap that you have to keep track of (finally lost mine), or no cap at all. This retractable design is ideal, and I really like the flexibility of the micro connector for tablets/phones/cameras. The integrated wire loop is perfect for attaching to a car key, lanyard, keychain, or anything else.Writes reasonably fast - 13MB sustained average for large files (1.5GB ISO file in under 2 minutes). Wrote 182MB (413 files) in about 20 seconds. That's not as fast as some others, but it's fast enough, especially for the price. My last two tab-style drives, (SanDisk & Samsung) wrote between 20-30MB/s. That was nice, but not necessary. Most cheap thumb drives are still far worse. Also, the smaller file performance was better than I expected. I will say the write speed was noticeably consistent, and I'd rather have a reliable, predictable drive instead of a blazing-fast one that is more volatile.Read speed is INSANELY fast - 150MB/s SUSTAINED to copy the same ISO file back to my desktop's SSD in just a few seconds. That's better than the Samsung Tab I am upgrading from. I guess that takes the edge off the slower write speed, since mostly I'm reading from this drive anyway.I used to carry the full-size Cruzer Titanium, but didn't like the extra bulk. I switched to the "Tab" format drives, which used a little lanyard-style thing to attach to the keychain. I loved how tiny they were, and having the removable clip was nice, but trying to get them in/out of the computer was a pain, especially with my big hands/fingers. I had a Patriot tab first, then upgraded to the SanDisk Fit - it was the easiest to remove because of its molded grip, and lastly the Samsung tab (64GB) was the best performing option. I have grown weary of the super-tiny form factor, and that it dangles off the key. This hangs close, so it won't snag on things in my pocket or tickle my knee while I'm driving (that should be reserved for my wife, anyway).

Love the capacity here! I have a head unit in the car with dual USB ports. Port #2 is for Android Auto hookup, and the first port can be used for a USB drive to store music. This is in addition to the SD card reader behind the panel. With 256GB, I can store a lot of high-res music (many at 24-bit, 88.2kHz or 96kHz) and not worry about running out of space. Combined with the 128GB SD card, I have some decent capacity in the car.Like other USB 3.0 drives from SanDisk, this one runs hot. The first two Sandisk Cruzer Fit USB 3.0 drives I bought ran alarmingly hot but several months later, it apparently does not affect their performance or durability, since they are still working great! If they had made the Cruzer Fit in an affordable 256GB size, I would have bought one of those instead. But for now, for the price, this product is small enough to stay out of the way and works just as well.The neat thing about this is that you can plug it into a standard USB port, or toggle the micro USB connector out of the opposite end to connect it directly to a phone. That, however, is a light drawback, as it makes inserting this drive into a standard USB port difficult at times. There is a small tab that sticks out from the site--you push this in to toggle which end you want the connector to stick out of, or to hide both connectors. The problem here is that when you go to insert this into a USB jack that has limited space, you have no choice but to grip it by the sides, and then the connector is slipping back inside the case. For most users this may not matter, but based on where I have my USB jack located, this is the most difficult of the thumb drives I've used to put in place. This doesn't hurt the function, however--it still operates as it should.
