SSDs are known for helping accelerate boot times. Queue depths during Windows start-up can easily exceed four, as the operating system accesses multiple files in quick succession or at the same time. This is exactly we see when Windows 7 loads up under VMware Workstation. Fewer than half of the operations occur at a queue depth of one. The vast majority of the transferred data is sequential, with about two-thirds of the operations 64 KB in size.
VMware Workstations takes as little as 30 seconds to reach the desktop. In comparison, our two Caviar Green drives in RAID 1 take about 50 seconds to get there.
I/O Trends:
- 38% of all operations occur at queue depth of one
- 55% of all operations occur at queue depth between two and five
- 75% of all data transferred is sequential
- 18% of all operations are 4 KB in transfer size
- 64% of all operations are 64 KB in transfer size
