PCMark Vantage is the first objective hardware performance benchmark for PCs running 32 and 64 bit versions of Microsoft Windows Vista. PCMark Vantage is perfectly suited for benchmarking any type of Microsoft Windows Vista PC from multimedia home entertainment systems and laptops to dedicated workstations and high-end gaming rigs. Regardless of whether the benchmarker is an artist or an IT Professional, PCMark Vantage shows the user where their system soars or falls flat, and how to get the most performance possible out of their hardware. PCMark Vantage is easy enough for even the most casual enthusiast to use yet supports in-depth, professional industry grade testing.


FutureMark has developed a good set of hard disk tests for their PCMark Vantage Suite. Windows users can count on Vantage to show them how a drive will perform in normal day to day usage scenarios. For most users these are the tests that matter since many of the old hat ways to measure performance have become ineffective to measure true Windows performance.

Here we see Vertex 4 next to Vector, both in 256GB capacities. Like us you have to be wondering what happened since the Vertex 4 delivers 300MB/s sequential read and Vector delivers just 350MB/s.

Here we see the latency at different sizes. AIDA64, our latency test can only measure 64KB, we've asked for the ability to change the transfer size, but after a year we've given up on the request. Anyhow, here we see that Vector is able to finish an operation faster than Vertex 4 at a queue depth of 1. At the 512 byte size Vector is nearly twice as fast.


What we think is going in Vantage is this. Vector can finish a read operation and start the next faster than Vertex 4. That is how Vector can actually outperform drives with SandForce controllers in Vantage despite being limited to just 250MB/s sequential read. Remember, Vantage is based on heavy low queue depth reads.
