Affordable external SSD
Installing an SSD (solid-state drive) inside your PC, and making it the drive Window’s starts up from, is a very effective way to reduce loading times for games and software, and make your system feel faster in daily use. But if you don’t fancy undertaking an internal upgrade, the USB 3.0 (and faster) ports found on all recent desktop PCs and laptops let you take advantage of SSD speeds with external storage, and it needn’t even be expensive.
This 240GB drive is cheap, and looks it, with a basic textured plastic case. Inside, however, is an SSD chassis much like the ones sold as internal SATA drives, and with no moving parts it should be hard to damage. Adata claims read and write speeds of over 400Mbit/s, but we weren’t surprised about getting results just shy of 300Mbit/s, falling to 148Mbit/s write and 227Mbit/s read with smaller files. It fell further to 27Mbit/s in the challenging random-access tests.
These are expected and acceptable speeds even for an internal SSD, so plugging in a drive rather than opening up your PC is definitely a viable option. It also means you could use the SV620 to share data between a desktop PC and a laptop, for example, because it’s small and light enough to slip in a bag, and doesn’t require a mains power supply. Per gigabyte, it’s expensive compared with a traditional hard drive, but not unreasonably so. A 480GB model, works out cheaper per gigabyte.
