SanDisk Extreme Portable SSD 500GB up to 550MB/s read

Product Information

There’s no getting around this: the KC2500 isn’t cheap. It is, however, outstandingly fast, in both sequential and non-sequential workloads; its CrystalDiskMark scores of 3,445MB/sec in the read test and 2,795MB/sec in the write test are just one showcase of its power. From SanDisk, the brand professional photographers worldwide trust to handle their best shots and footage. SanDisk’s Extreme v2 is a bit bigger than the original, measuring 101 x 52 x 9 mm and weighing in at under 63 grams. With a carabiner loop integrated and a durable silicone coating, the Extreme v2 features a functional, portable, and enduring design for those on the move in tough conditions. But unlike the Extreme Pro, the Extreme v2’s case and internal structure is made of plastic rather than rigid aluminum. This makes for a small and compact design that is also pretty light, but a little less resistant to twists and bending. 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.

SSDs are the best choice when it comes to storage. They’re far faster than old-school mechanical hard disks and a lot more compact. It doesn’t hurt that SSDs are also completely silent.

Game Longer

Muchas veces llegan a mis manos equipos portátiles o equipos sobremesa que quedan obsoletos y el dueño solo los utiliza para ver el correo o navegar por internet. Flash memory based drives have now implemented a special "wear" algorithm, such that new data is written on cells that are not progammed with data, and so files are moved continuosly across the drive to mentain a balance of erase/program for all the cells, otherwise if a file is continuously written and modified on the same memory cells, these will wear after those few hundred of cycles and not be able to be used anymore. That is why a worn out SSD drive, that has reached a TBW spec, will not retain the information for long. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:

However, while speed is important, it’s not the only consideration. We also look at the price of each drive, its TBW rating, and any bonus software or accessories that come with it. For external drives we also consider the physical design, particularly the portability and toughness, before arriving at our recommendations. 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.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?

Yes, there are cheaper alternatives out there, and most of them are fine for casual usage. But if you’re looking for a fast and reliable SATA SSD, Samsung’s 860 Evo is your best choice. Of the models on offer, Samsung’s 860 Evo is our favourite. It’s not the cheapest, but it’s one of the fastest SATA drives available, with performance that hits the very limits of the SATA connection’s capabilities. In CrystalDiskMark’s sequential read test, the 860 Evo averaged an unbeatable 563MB/sec, with equally impressive sequential write speeds of 532MB/sec. It also achieved an average of 479MB/sec in the large-file read test, which again puts it in the very top rank of SATA drives. Up to three-meter drop protection and IP65 water and dust resistance 5 mean this durable drive can take a beating. Ruggedized design with a forged aluminum body to protect the SSD core and dissipate heat. Plus, a durable silicon rubber coating seeks to deliver higher impact resistance with its IP55 rating for water and dust resistance. 1 Aunque para equipos de gama alta de última generación no recomiende este tipo de discos a no ser que se requiera la interfaz SATA obligatoriamente (M.2 es mucho más rápido), como técnico puedo decir que para el usuario medio estos discos aportan una solución más que aceptable que aumentará el rendimiento del equipo exponencialmente, de hecho, muchos clientes han quedado asombrados con el antes y el después de la actualización.

We've rounded up the best SSDs for slick, speedy and clutter-free computing

When it launched last year, the A2000’s amazing price-to-performance ratio instantly made it a top M.2 SSD, and even against the ravages of time – and newer, faster drives – it still stands out today.
