The low profile 128GB CZ43 Ultra Fit USB 3.0 flash drive from SanDisk offers a read speed of 150 MB/s to provide fast access to your videos, images, music, and files. This flash drive features USB 3.0 technology that moves data between devices ten times faster compared to USB 2.0. With a tiny design so you hardly know it is there, the flash drive can stay attached to your notebook, game console, TV, in-car audio system, and more, to provide an ever present storage capacity of 128GB.

SanDisk includes two downloadable software programs that provide security and recovery for data stored on the flash drive. SanDisk offers SecureAccess software compatible with Windows and Mac systems, which creates a password protected private folder on the flash drive. The folder is 128-bit AES encrypted, so you can share the flash drive with other people while protecting your sensitive information. In addition to the security software, for one year SanDisk also includes RescuePro for recovering accidentally deleted files from the drive.

    SanDisk SDCZ43-128G-A46 reviews

    128GB CZ43 Ultra Fit USB 3.0 is rated 4.3 out of 5 by 116.
    Rated 1 out of 5 by from Runs extremely hot, mediocre speeds I bought two of these and returned them. The average read speed I got on them was around 60MB/s and they ran very hot. The first time I used one, I went to pull it out and burned my thumb on the metal. I put a meat thermometer on the outside of it and it registered 120 degrees. I was afraid the heat would ruin my USB ports. While the size of them was certainly impressive, the performance and heat were completely unacceptable. SanDisk is generally a great brand and I use many of their other products with great success for video and audio projects, but stay away from these little guys.

    Rated 2 out of 5 by from Lots of storage and inexpensive, but poorly made/designed This USB key gets really hot. In some computers, it's not a problem, but in others (maybe when it's connected to a powered USB hub?), it gets so hot that it goes in what I assume is thermal shutdown, and it disconnects from the computer, after 1-2 minutes of use. Then, as it cools down, it reconnects. And disconnects again after a short period of time when it gets burning hot again. When it's not overheating though, it works as expected and provides lots of storage for cheap.

    Rated 5 out of 5 by from SanDisk Ultra Fit USB 3.0 I had been looking for this product in the U.S. for over a month and couldn't find it. But then I finally found it and B&H Photo. I got the thumbdrive in 2 days and it is everything I wanted from the extra storage. It is fast, hardly noticeable, and holds a lot of data. I use it with my work laptop to hold a lot of documents, portable applications (utilities) I use throughout the day, backup of my most important files, and even threw in a couple of ISOs on there. I can't say enough good things about it. And the price from B&H Photo was about $$less than anywhere else where I was able to find it. I highly recommend it.

    Rated 1 out of 5 by from Do not believe the Read/Write Speeds I like the size of this device but that may be a contributing factor to its problems during heavy usage, i.e. small size equals not enough heat sink area. This device works okay for brief periods of time during writes but then slows to a stop for a period of time before continuing. Write speed on USB3 starts at 70MB/s then slows to about 10MB/s. Previous reviewers have indicated that they had excessive heating problems on this model and I believe that SanDisk has fixed that problem by throttling the write operation. Essentially the write operation just stops when the heat level reaches the device limit and then resumes after it cools down. Avoid this product, it has problems.

    Rated 4 out of 5 by from Works Great so Far - Will Probably Purchase More of Them I've purchased three of these 128GB CZ43 Ultra Fit USB 3.0 devices for various applications. So far, they all are working as intended. I think the small form factor will reduce the possibility of accidental damage to other components or devices that a larger form-factor thumb-drive that could cause. This smaller form factor does not extend out from the USB port and seems less likely to snag or be hit by other objects - in my case the USB ports in my vehicular entertainment system or my laptop computers. The four-star rating is because I have not had a chance to fully test this device in all the probable applications I envision for it. So far this device has fully met my expectations in my applications.

    Rated 1 out of 5 by from Doubles as a portable stove. I just bought two of these. The drive gets so hot when plugged in that I burned myself on the metal plug when I pulled it out. A little research revealed that this is a recognized design flaw with the drive. There are a handful of reports of it damaging equipment and blistering the plastic on usb hubs and such. I won't be using these things for fear that they will damage my laptop. Do the research.

    Rated 5 out of 5 by from Fantastic This flash drive is fantastic. To address some of the negatives people have posted: Yes it gets hot, but this hasn't been an issue for me. Yes your computer only reads this as 115GB. This is because of the way your computer and storage manufacturers count how many MB are in a GB. Storage manufacturers count 1000MB per GB, your computer counts 2^10 or 1024MB per GB. No this is not false advertising, and hard drives do it too (750GB HDD shows up as 698GB, etc). The flash drive comes formatted as FAT32, so single files larger than 4GB (like some movies) won't transfer onto it. Reformatting it to exFAT or NTFS will solve this issue, although it may cause incompatibility with some other devices. I get speeds of 40+MB/s over sustained writes to the flash drive, consistent 120+MB/s read from the flash drive onto my SSD. Also people complaining about size: really?? It's meant to be small, it's marketed as a small form factor, duh it's going to be small. If that means it's too easy to lose for you, get one with a bigger form factor. Not exactly rocket science. Overall I'm very happy with it, especially for how cheap it is too.

    Rated 5 out of 5 by from Works I'm only running it on USB 2.0, but works fine. I keep it in my dead USB port on my laptop when not in use because it does get hot if you leave it in an active USB port. Never too hot to touch, but quite warm. My hard drive on my 10 year old laptop is only 160GB, so this is a nice edition for some extra storage. Nice and small to leave plugged in all the time. Only sticks out about a 1/4 inch. Plugged in on my XP machine it shows 115GB total, formatted FAT 32. Write stats for a 1GB file to and from my 5400 RPM laptop drive: From hard drive to flash drive : 1' 11 From flash drive to hard drive: 0' 40
