In general, its read speed is rather impressive. This drive allows you to handle files directly from it and don’t have to copy the content to the hard drive. There are four available capacity standards (128GB, 256GB, 512GB and 1TB) for this drive. Es cierto que se calienta el USB durante su uso, pero no es algo relevante, ya que no influye para nada, no reduce el rendimiento, y es algo común en las memorias USB, de hecho es mejor que se caliente que no que esté frío, ya que si se calienta significa que está disipando correctamente el calor, mientras que si no se calienta puede significar que los materiales exteriores son aislantes y no disipan correctamente el calor, quizás el exterior esté frío, pero en el interior puede estar demasiado caliente.

SanDisk boasts that a full-length 4K movie can be transferred in 15 seconds. It took about 40 seconds to transfer Avengers: Infinity War with an average write speed of 135 MB/s as we reached the upper limits of what our internal hard disk could handle (about 140 Mb/s).

After testing by UseBenchmark, the 4k-read speed of Samsung Fit Plus is 14.3 MB/s and the 4k-write speed is 12.2 MB/s. It has a capacity of 128GB. If you use a portable operating system, this drive is helpful for performance enhancement. Read speeds up to 420MB/s, write speeds up to 380MB/s. USB 3.1 Gen 1 or USB 3.0 port required. Based on internal testing; performance may be lower depending upon host device. 1MB=1,000,000 bytes. There have been some questions about my testing on this drive. Thought I would add a bit to how I came to my 3 star rating. I am adding a photo that shows a few different test. The first two at the top are the Sandisk on my Surface Studio. I did test it on a 2016 Macbook pro that has 3.1 built in and as you can see it does get a bit higher numbers. For full disclosure since this is type a connector had to use a dongle but I get higher speeds through that dongle with other drives.

Corsair Flash Voyager GTX has the fastest read speed, so it can also be considered as the fastest USB flash drive. Its read speed can reach 368 MB/s even tested by UserBenchmark. The advertised write speed is 440 MB/s, but the tested speed only reaches 175 MB/s. Generally speaking, solid state drives are faster and perform better than their hard disk counterparts. We expected to be blown away by the SanDisk Extreme Pro, especially since it advertises transfer speeds around 400 MB/s. Unfortunately, the results didn’t quite add up.

Compré esta memoria USB en mayo del 2020, por unos 54 euros, actualmente ya ha bajado a entre 35 y 40 euros, en su momento era 3.1, ahora es 3.2. Las velocidades que dice que se alcanzan en el anuncio son reales, tal cual, pero solamente se alcanzan en archivos grandes, lógicamente, ya que cuando son archivos pequeños, la transición entre un archivo y otro hace perder velocidad, algo que ocurre con todas las memorias, pero aún así la velocidad es muy rápida.In the end I still give this 3 stars as it should perform reasonable on both Windows and Mac. (IMO) If you are only using Mac than this would be 4 stars. Also the random read and write are simply just sad slow compared to other drives. Where this can be felt is loading a large Premier project with lots of little video clips. In my testing it took at least double the time to load the same project compared to the T3 or 850 Pro. J'aurais pu ajouter des photos (saisies d'écran), pour illustrer les vitesses de transfert de fichiers. Mais je n'en ai pas fait. Désolé !... Je ne vous dis pas de me croire totalement, malgré le fait que j’ai un talent de persuasion évident, je le conçois ! Mais je vous demande de croire en mon objectivité et transparence absolue ! Blazing-fast performance lets you transfer a full-length 4K movie to the drive in less than 15 seconds1 or 1000 photos in less than 25 seconds 2. The SanDisk Extreme PRO USB 3.1 Flash Drive features an elegant yet durable aluminum metal casing to help protect the drive from everyday wear and tear.
