SanDisk Ultra 3D ssd 500gb Review: Quick, quick, slow
SanDisk Ultra 3D ssd 500gb Review – For a while, SSDs were faster than hard drives but pricier, so they competed to offer even more speed to justify the outlay. It’s now got to the point where every decent SSD can reach speeds of over 500 megabytes per second (MB/s), which is about as fast as the SATA III interface can handle.

That leaves only two options for manufacturers: switch to a new interface and offer even higher speeds, or compete on price.

SanDisk reckons this can deliver up to 560MB/S read speeds and 530MB/S write speeds, slightly faster than Samsung’s popular 860 Evo (see our review, Issue 530). Doing the simplest of file transfers, the Ultra 3D even beat these figures, but in more demanding tests the Evo was 50 per cent faster. In real-life tasks they were closer, but the Evo still won.
