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. In performance tests, however, the BX500 acquitted itself very well. It blasted through CrystalDiskMark’s standard sequential read and write tests at a very decent 562MB/sec and 525MB/sec respectively, giving the Samsung 860 Evo a run for its money. It struggled more in our small-file tests, with read and write speeds dropping to 257MB/sec and 301MB/sec respectively, but this is still a drive that will give your PC that unmistakable SSD snap at a great price. 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.

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.

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. It does come with a caveat: the drive has a relatively low write endurance of 120TBW for the 480GB model. That should do you for many years if all you want to do is run everyday apps and games, but we’d be wary of recommending it for a productivity workstation.

As for external drives, most current models use custom designs that don’t match up to either the SATA or M.2 standards. And that’s not a problem – focus on performance, size and other factors instead. Is it worth paying for the fastest speed possible? 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 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. SanDisk Extreme Pro leverages our lightning-fast in-house NVMe technology to dramatically increase transfer speeds to up to 1050 MB/s 6 and fully saturate the USB 3.1 Gen 2 interface. 6 So you’ll be able to edit right from the drive – providing full-frame editing with little interruption while saving you time and keeping your computer’s internal storage free.Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: So I spoke to and shipped the product to Western Digital (SanDisk is now owned by them) as it was still under warranty. They SAID they are going to send me a replacement. 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. 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?

En estos momentos y hablando de interfaz de conexión SATA, puedo decir que SanDisk ofrece una calidad precio estupenda, ya que por apenas menos de 10€ de diferencia respecto a proveedores más económicos tienes un disco de buena calidad, con una tasa de transferencia más que aceptable para el tipo de conexión que utiliza, 500 - 550 MB/s de lectura escritura (secuencial).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. The Extreme PRO® SSD works with PCs and Mac™ computers right out of the box and connects with USB Type C and Type A, 3 making it easy to start and keep working in almost any situation. 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. Up to three-meter drop protection and IP65 water and dust resistance 5 mean this durable drive can take a beating. 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.
