    Using as an OS boot drive

    I bought this to use in a server build as an OS boot drive. My OS (Linux-based) installs usually take no more than 4-5GB, so this is total overkill. But this size made it also useful for other purposes and at the price I paid, it was the best $/GB. I read elsewhere that this flash drive has a tendency to get really hot. In fact, because of such reviews I read, I was considering the equivalent Samsung model. In fact, I got both for comparison. What I found out is that in a USB 3.0 slot, under heavy writes, this drive does indeed get hot, but in my opinion not so hot that you can't handle it with your bare fingers; some might have more sensitive fingers than I so YMMV. When compared to the Samsung option, this drives seems to have better sustained performance, where as the Samsung has a tendency to slow down under sustained writes (like if you're transferring a 30GB file). However, when I've used this drive in USB 2.0 slot, albeit with slower performance, it does not get hot at all. So, if you're worried about this thing getting hot, consider the above. Either way, as an OS boot drive, which typically has a lot of smaller files they both perform well. I've been using this SanDisk one in the onboard USB 2.0 slot of a Supermicro motherboards to have a bootable OS that I can use to test out the hardware and run diagnostics. It has worked great in that capacity for quite some time now. Since it has such a high capacity, it allows me to install all the various hardware diagnostic tools I need for multiple platforms. I've been considering partitioning this drive so I can triple boot Linux, FreeDOS, and Windows so I can have access to diagnostic tools from all 3 OS platforms. The FreeDOS is especially useful for doing BIOS/Firmware flashing.

    Expands Macbook Air Storage

    Using this small and relatively inexpensive USB memory stick, you can increase the disk storage capability of any laptop (or desktop) computer easily and compactly. In my case, I used it in conjunction with the internal 128 GB SSD drive on an older 11" Macbook Air to give additional room for file storage. Taking some files external allowed for some free space on the already crowded small SSD storage drive built into the computer. Although the USB stick is very small, it protrudes only slightly from the side USB port. The USB stick is not as fast as the internal SSD drive (not even close!), however, it's speed is perfectly adequate to be used for accessing iTunes music files, photos, saved emails or Word documents,etc, and still deliver acceptably fast file save or load times. Another advantage of external storage is you can use multiple USB sticks and interchange them as needed to provide even more storage space, or use them for designated task purposes (e.g., Music file USB stick, Word document USB stick, Spreadsheet USB stick, etc.). They are very small and do not require much room to stow. Overall, this device meets my performance expectations (i.e., providing additional compact file storage) very well.

    My New Go To Flash Drive

    Ironically, I didn't seek out the SanDisk flash drives specifically, I needed some drives in a pinch to back up some files before I installed a new SSD. These compact USB 3 flash drives were the one's on the best sale at the time and my wife went and got them in the morning for me. I had no expectations, but the read/writes on these little guys was really fast. In fact it was probably the fastest "standard" USB 3.0 Flash drive I've ever used. Granted, I did not benchmark them while I was working but in real world time they seemed much faster than the Adata, Samsung, PNY and Lexar drives I had used in the past. They have better specs than the larger, more basic versions of the same brand, though (maybe because they're newer?) and I wrote over 35 GB's of music to it no problem. Unlike the metal Samsung drive I have, which gets so hot you can cook on it , the temperature of these remained cool. My only complaint is that they are actually kind of too small and they are difficult to pull out of their little cover if you have larger hands. Overall, I was very pleased with this purchase!

    Works flawless on Mac

    This is a great semi-permanent storage solution for laptops. The only downfall is that they can be misplaced easily, but of course that's my fault, not Sandisk. The write speed is actually faster than the typical size USB 3.0 thumb drives I have by Sandisk. It is super fast in my MacBook. I just reformatted the disk to Mac OS Extended using Disk Utility to help make sure I get the best read/write speeds. I have heard that your Mac won't properly sleep unless the disk is ejected. I usually just shut my Mac down anyways sorry it's not an issue. However, if you keep your MacBook in sleep mode at night, I recommend "ejecting" the drive, then put it in sleep mode. No need to physically take the drive out as far as I know.

    Not really 64GB

    • My Best Buy® Elite Plus MemberElite Plus Member

    The great thing about this USB 3.0 drive is it seems to write data at least twice as fast as a USB 2.0 drive even when the socket is USB 2.0 I have never had a problem with the operation of a SanDisk storage device and anticipate no problems with this device. According to the drive "Properties" tab of this drive the usable capacity of this "64GB" USB 3 drive is 57.8GB. Further the actual max capacity of the drive is 61.481 GB. I suppose the consumer electronics community has this uncontrollable tendency towards hyperbole but really SanDisk, isn't a 6+ GB overstatement of stated capacity a bit much? I have purchased 20 or so SanDisk USB 2.0 drives over the years and can state that all have worked reasonably well and are still working; a few have gone thru my washer and dryer several times and they still work! I just shake my head in wonder when a provider of quality storage devices so grossly misrepresents a product.

    Perfect for car USB ports

    My Volvo has a slot for a USB drive, yet traditional sticks tended to get bumped and moved around too easily. This was causing problems with the audio system being able to read the drive, even leading to an instance where the audio simply wouldn't play. After doing some looking online, I found these super short drives, and they have been absolutely great. When you see a picture of them online, it's hard to tell, but most of the length actually slots into the USB port, so all that pokes out is roughly 1/3 of an inch high. This is perfect for my car's USB drive in the center console, since it sits flush, and no longer is anything able to knock against it, or jar it loose. Transferring files is pretty fast, and my car reads and plays the music no problem, no lag. Overall, if you're looking for a great USB drive with a low profile, THIS is the one to get. Awesome product, and I would purchase another one in a heartbeat if I needed to.

    Perfect for Car USB

    I picked this up for the sole purpose of using in my car, which can play music from a USB flash drive. The USB port is in my center console and I didn't want to have a long flash drive that I would hit or knock out of the port when I was getting things in and out of the compartment. This was a perfect fit. Its small, and you would never even know it was there if you weren't looking for it. The price was decent for 64 GB and I haven't had any problems using after several months of use. The only issue I would note is that the device does get very hot--to the point where it will burn your fingers a bit--when you take it out of the port. This doesn't seem to affect the device's use, but is something to consider.
