SanDisk Ultra Plus vs Crucial V4

Intro

SanDisk-Ultra-Plus-SSD-300x229The Sandisk Ultra Plus SSD is one of two solid state drives simultaneously introduced by SanDisk at the start of 2013. This SATA III 6 GBps drive can deliver peak perfomances of 530 MB/s and 445 MB/s for sequential read and write respectively while IOPS for 4k random read is 82,000. It uses Marvell’s 88SS9175 controller, an improved version of the 88SS9174.

crucial v4In comparison, the Crucial V4 is a low-cost SATA 2.0 (3 Gbps) drive based on Phison’s PS3105-S5 controller. The maximum sequential read and write speeds in the V4 are 230 MB/s and 190 MB/s, respectively. The V4 is available in the capacities 32 GB, 64 GB, 128 GB and 256 GB and uses 25nm MLC NAND modules from Micron.
