Let's just discuss the time scale. The processor of your computer lives by the nanoseconds: the majority of the CPU can do several things for one nanosecond; generally, these are the simple math and the comparisons. To make this perception easer, we assume that you are the processor, and instead of nanoseconds you live and work second by second. In order to make it clear, we apply this metaphor to the single-core processor.

Improving performance of the disk subsystem is the most topical issue today. This is caused by the low cost of HDD that takes a leading position in the mass segment. More than a half of the resource-intensive applications have a "vulnerable spot" that are the spindle drives. In this case, everything does not depend on the bandwidth of SATA interface, but it depends on the physical capabilities of the mechanical components of the magnetic disk. The bandwidth of SATA-II and SATA-III interfaces makes 300MB/s and 600MB/s respectively, and the maximum performance that can provide a regular HDD does not exceed 150MB/s. Therefore, the transition to SATA-III-interface will be reasonable only for SSD, but it is not suitable for everyone.

In order to evaluate and to test the effectiveness of different types of disk subsystems were chosen following solutions:

1. OCZ RevoDrive X2 PCI-E SSD 100Gb


2. Plextor PX-128M2S SSD 128Gb

Here are the results of user poll on the SSD reliability that could be useful.

Let us begin with the size statistics.


The picture shows that the most popular formats are 120, 80 and 60, which are released only by Intel.
It is also noticed that the drives with capacity of 120 / 128 are particularly popular among users of alternative operating systems (including OS X).
