USB 3.0 Flash Drive KOOTION 10 Pack 32GB Thumb Drive 3.0 USB Stick Keychain Memory Stick Swivel Jump Drives, Mixcolors

This is a review of the USB 3.0 32GB drive 5 pack. Not the USB 2.0 drives also in this product listing. Thumb drives are a commodity for the most part so looking at performance vs price is my metric. I wanted a set of assorted color drives to use in my IT practice to carry around various bootable tools including various version of portable Windows. This pack was exactly what I needed and they perform very well for my purpose. I ran a CrystalDiskMark on one of these in a USB 3.0 port on my laptop. Sequential reads were just under 110MBs which is about 2.5X what I get from a USB 2.0 drive, so USB 3.0 performance for sure. Random reads were less than 1/20th of the sequential reads at about 5.5MBs. Writing for sequential and random writes was *much* slower than reads. So what does this mean in my "real world" assessment? These drives are mostly reading files sequentially. After creating them there will be a lot of reading and very little writing to them. In other words they are well suited for my techie needs. Other applications where these might shine are to store or as a backup for music or photos where you write once or when you add more media and read a bunch more than you write. These are not the fastest USB 3.0 drives I've owned by quite a bit. There are some very fast thumb drives! But generally speed comes at a price and these are very inexpensive for USB 3.0 32GB drives. Construction is typical for economical thumb drives which isn't bad. I expect these will hold up to lots and lots of plugging and unplugging. In conclusion what matters to me is value and for their low price they give me everything I'm looking for. If you are looking for a good drive at a low price this may be an excellent choice. If your priority is a super-fast thumb drive and you're willing to spend more, then maybe not. Since they hit the mark exactly for me I'm giving this 5 pack of thumb drives 5 stars.

Worked as described. All came in FAT32 format so if you need to store larger files you will want to reformat to NTFS or exFS before you start using the drive.

A lot of large USB sicks for the money. Great for OS recovery, and large single use.. LINUX, windows and Pagefile were quite bad performance Jumping around and WRITES simply not what USB thumb drives are for.. REAL LIFE PERF now WELL USED, Over half full and at one point FULL used drives are much slower I think I even beat on this one as LINUX + Pagefile on a 2GB DRAM system for 2 weeks Write to that is a worst case.. 2 GB very compressed ISO to 90 sec to copy from SSD Windows said 20 MB/s TRUTH My paging tasks will go to much more premium drives not optimized for lowest cost and size. .. 50MB/s was fairly common when new USB3 5gb would be 400MB/s real life with SSD These $6 ea drive.. could never compare. I WOULD BUY AGAIN for normal peoples usage

Good performance and an excellent value

Works great for transferring movies or data from iPhone to computer.

Great for photo and data transfer off line with cell phone.

A funcionado muy bien

I bought these to set up recovery images for my computers. They work fine.

Relación calidad precio

Igual que las demás memorias caras que tengo, funcionan bien, rapido y no se han trabado. Compré el paquete de 5 y probé las 5, cero problemas... Las recomiendo, sobre todo para poder pasar datos a otros sin estar esperando ver si te regresaran tu memoria.. por el precio son buenas para eso.

Llegaron en el mismo empaque antes de lo esperado. Funcionan correctamente.

Siempre de buena calidad es mas ahorita voy comprar mas

Ahorras mucho al comprar el paquete y funcionan muy bien y rápido
