Why do you have to read this post till the end? Any server owner with time faces performance issues. Sites start opening slowly, database inquiries take more time, waiting for application response and so forth. We can say that this is he other side ofproject development – huge page traffic, increased size of database and number of users on server. First thing people usually do in this situation is upgrading RAM and processor, and eventually – server replacement to more expensive one. However in most cases replacing HDDs onto more efficient solid-state drives (SSD) solves the problem with lesser expenses. What is a solid state drive? In effect, solid state drives use principles similar to Flash-cards but in terms of technology SSDs moved well ahead. Modern SSD is quite a complex data storage system. Disk controller monitors the condition, adjusts usage of different blocks to make sure that wear-out is even and also replaces bad blocks with new ones from a special reserve. The size of such area in top manufacturers can reach up to 10% of the basic storage capacity. Since SSDs don’t have mechanically mobile heads no time needed to position them. Read/write speed of SDD cell is several times higher than of HDD and transaction can occur in several flows. Absence of moving parts reduces disk overheating and hence energy consumption. Mechanical reliability of SSDs increases year by year. Their life cycle is still estimated on the basis of write cycles, although nowadays manufacturers guarantee at least 3 to 5 years of flawless operation. Perhaps there won’t be full conversion to SSDs in the nearest future, but area of application will definitely continue expanding.
