Whilst the literature claims to the contrary, the drive's sequential read and write speeds are a touch lower than the model it replaces, according to figures produced by CrystalDiskMark.

The Toshiba-powered V+ is competitive when moving 512KB files around, beating out the older drive in both and trading blows with Corsair's X128.

Random 4K read speed isn't great, clearly, but the 4K writing is excellent, which is often the Achilles Heel of all but the very best SSDs.
