SanDisk's poor Vista performance

Down to SlowDisk SSD speed?

SanDisk's complaint that its solid state drive (SSD) products don't accelerate Vista PCs and notebooks because Vista is not written to use SSDs could be cloaking a native SanDisk SSD performance problem.

Here are some comparative performance numbers at the 60-64GB capacity level:-

	Write Speed	Read Speed
SanDisk SSD SATA 2.5-inch	47MB/sec	67MB/sec
Super Talent SATA II 2.5-inch	100MB/sec	120MB/sec
OCZ Core Series SATA II 2.5-inch	90MB/sec	133MB/sec
RiDATA SATA Ultra-S Plus 2.5-inch	to 80MB/sec	to 128MB/sec

The figures are for sustained read and write speeds. SanDisk uses a 1.5Gbit/s SATA I interface.

The SanDisk product is substantially slower in its native performance than competing SSDs. Vista may well be written without efficient code to use SSDs but, that being the case, faster SSDs will outperform slower SSDs and it looks as if SanDisk SSDs are SlowDisk SSDs.

We can expect a radical overhaul of SanDisk SSD speeds within the next few months.
