This article is a must read for anyone contemplating buying a SSD in the near future.What is SSD and how is it different from traditional hard drive?
SSD stands for Solid State Drive. It is used for mainstream modern day PC/laptop. PQI SSD includes double headed USB cable for use as an external hard drive. SSD is shock proof and provide faster read/write speeds over traditional hard drive.
How Fast is Fast?
Presently, the only SSD capable of reaching stable performance results of 170MB/s read and 100MB/s write speed is PQI SSD.
The performance misconception
The true performance of an SSD cannot be understood unless one has had the opportunity to utilize one. Even watching a short deom is not a fair representation. We are so used to grading the performance of a HD by its read and write benchmarks that we instinctively look to this from the SSD as well.
The magic of the SSD comes less so from the read and write benchmakrs and more so from the incredible access speed that it can achieve. An SSD searches similarly to that of your PC. It finds something by index and then retrieves it as the computer would from RAM.
With the typical consumer owned hard drive, it take 10-15ms, on average, to find information and retrive it because of the disk spinning, arm pivoting above and having to find the information on each pass and so on. This is compounded by the fact that a large file on a HD can take several passes to retrieve, each pass being 10-15ms on average compared to the 0.1ms total time of the SSD. This is why so many programs seem to open instantly with an SSD. Diagram of SSD:
Since there are no moving parts in SSD, this occurs as quickly as 0.1ms.
How long will they last
"The SSD will outlive the hardware for which it was built for."
