Product Information

From SanDisk, the brand professional photographers worldwide trust to handle their best shots and footage.

Es más pequeño que un iPhone 6, lo que lo hace muy cómodo para transportar ya que cabe en un bolsillo y además es muy ligero apenas pesa nada. Another thing about the flash memory is the indurance of the cell, how many times the memory cell accepts write/erase cycles until it starts to "wear" and not store anymore the information. That number is in the hundreds now days. If you read correctly the specification of an SSD drive, you will find a specification called "TBW", total bytes written. Dividing that number by the capacity of the drives yields the number of erase/write cycles that will wear the cells. There are some caveats. QLC is slower than TLC, so the 870 QVO can lag behind the rest of Samsung’s typically blazing-fast SSD catalogue, and the larger models are serious investments. Then again, measured on a cost-per-gigabyte basis, their immense size does result in a certain kind of value: the 8TB model, for instance, works out at a mere 5p per gigabyte.However, its size makes the Samsung T7 Touch a perfect travelling companion, while the biometric scanner will provide peace of mind.

The small and light form factor of the Extreme PRO® SSD means it couldn’t be easier to keep your content with you whether you’re crossing town or traveling to an international location. For most people, any SSD will be fast enough to provide a snappy experience. But if performance is important to you – perhaps you’re a photographer or video editor working with very large files – there are a few metrics worth looking at. The first is sequential speed, which reflects how fast a drive can continually read and write large streams of data, such as raw video files; we use the CrystalDiskMark benchmark to measure this. The second is random-access performance, which gives insight into how a drive will fare when lots of programs are accessing it at once. We test this by copying a folder full of small files to and from each drive and measuring the average transfer speed. Is it safe to keep my programs and files on an SSD?Now, to answer your question, powering up the drive containing that memory does not refresh it's content. You can keep it powered up continuously, the information stored in the transistors is NOT UPDATED OR REFRESHED by the power applied to device, unless you write again the information. This principle of refreshing the data from time to time is used in the RAM memory in computers, and losing power leads to losing data.
