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

Product Information

We devote hundreds of hours of rigorous testing to help make sure your drive is worthy of your best work — and so you know your precious files are in good hands. But how fast is it? We measured a decent read rate of 912MB/sec in our test, which is slightly down from the promised 1,050MB/sec. Write speeds were lower, but they still exceeded anything you’ll get from a SATA connection. It lagged behind SATA rivals when it came to random-access performance, though.

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.

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. Get extra peace of mind with a 5-year limited warranty 3 and a durable silicon shell that offers a premium feel and added protection to the drive’s exterior. 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.

Get fast NVMe™ solid state performance featuring 1050MB/s 2 read and 1000MB/s 2 write speeds in a portable, high-capacity drive that’s perfect for creating amazing content or capturing incredible footage.

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. 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.The result is that in most use cases, the A2000 can compete with the very best on performance for an awful lot less cash. In fact, it’s even cheaper than the likes of the WD Blue SN550 and Crucial P2, so it’s arguably the best budget M.2 SSD as well. SATA SSDs aren’t as speedy as M.2 models, but they’ll still make your computer feel far snappier and smoother than any mechanical disk – and they’re compatible with a wider range of laptops, desktop motherboards and storage appliances. 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.
