SanDisk Cruzer Ultra 16GB USB 3.0 Flash Drive SDCZ48-016G-U46 up to 100MB/s (Pack of 5)

These drives have a relatively low capacity, but that was what I needed in this particular case to share some large files with friends. All Sandisk files I have ever purchased have been reliable, and these are no exception.

Work exactly as intended. I needed a couple of relatively fast but affordable USB 3 sticks with 16GB+. This pack fit the bill. I use them mainly for writing ISOs to and installing OSs on computers. Using them to install Windows (10, server 2016) and Manjaro Linux on machines with SSDs usually takes 5-10 mins tops to install (so pretty fast). They of course work for putting files on as well with decent write speeds and good read speeds. I like to have a couple on hand and occasionally lose one here or there so I am very likely going to purchase another set in the near future. I would certainly recommend these to anyone needing a handful of relatively fast, reliable and affordable USB 3 drives

I am extremely pleased with this merchant, and will buy again, and again. I train entrepreneurs, sales managers and their sales people, along with client/customer - and it is always a tremendous positive when you receive service nearly as quick as the speed of light!

I bought these to have a set of administrator images for various software packages that I manage for my company. For that purpose they work fine, read speeds seem to be good and the lanyard loop lets me keep all my drives together so I can find the one I need easily. The problem, as others have stated, is the write speed. At an average of 9-10MB/s it is painfully slow for a USB 3.0 device. Its not a deal killer for me since I am writing once and reading many times rather than constantly changing the files on the drives but for anyone using them for actual data transfer, look elsewhere for something that at least approaches the claimed speeds. Up to 100MB/s is seriously misleading when I have never seen one of these drives achieve anything better than 12MB/s for any length of time. And for those who may try to discredit my comments, the speeds Im seeing are consistent across over a dozen PCs of varying ages and specifications as well as transfers of many small files or a single large file. If i was using these for anything other than static storage I would have returned them immediately.

Very easy to order. Great prices.

work great, use for extra storage capacity

Formated well with no bad spots, worked well.

I love that these have an easy way to add a keyring to each one. They have enough room to create a label on each USB. These are great for college - I am studying I.T. so these really helped to keep my programs and studies organized.

Why buy 16 GB flash drives when 32 GB are only a buck or two more? Because sometimes all you need is 14 GB or less, like when youre creating a Windows 10 installation drive. Why do I keep referring to 14 GB instead of 16? Because 14.3 GB is the amount of usable space on a 16 GB drive. (Its because GB means different things to Microsoft and to drive manufacturers.) By the way, when they say up to whatever MB/s they mean read speed. Write speed is much lower.

Bought my wife a new truck with a really nice stereo and were using these for music. Ive used SanDisk Flash drives before for this purpose in My truck. Ive had cheaper brands fail, but Ive never had that problem with my Sandisk drives.
