SSD (solid-state drive) is a data storage unit It is an electronic assembly of flash memories (solid semiconductor while our good old record hard (HDD) combines electronics and especially mechanical operation. The defects of the latter are friction which causes wear and noise as well as a certain fragility. An SSD is less fragile than a disk hard, the trays of the latter being most often made of glass. SSD offers more access time shorter than a conventional hard drive (130 times faster!), Their speeds can cap at 550 MB/s in reading and 500 MB / s in writing in SATA III. Electric consumption being low, the SSD is an ideal candidate for laptops, ultra portable as well than tablets. The first SSD models had the huge disadvantage of seeing his performance decrease over time.

This still exists because a slowdown can be noticed when all cells have been enrolled. Rewriting on a registered cell is a little longer compared to blank cells. Fortunately a parade exists, it is the TRIM command that exists since Windows 7. The TRIM is responsible for resetting at the following, in real time, the sectors marked “Deleted”. The performances will therefore be maximum see you next time on this cell. There are two types of flash memory: MLC (Multi level cell), the least expensive and therefore rather reserved for General public. The SLC (Single level cell), more oriented to the pro. The difference ? The MLC is less efficient and has a lower lifespan than the SLC. 10,000 against 100,000 entries erasures.

Optimizing the system for SSD I pass on the installation of the unit SSD in the tower or laptop, because it installs like a HDD in SATA. We must now get to the heart of the subject, install Windows (or others system) Before that, enter the bios (attention this is for users only warned!) to verify that the management storage units be well in AHCI, because the SSD works in mode AHCI. AHCI mode allows connections hot and high speeds among others.

Why optimize your SSD?

Simply for him to work to the maximum of its capacity and that it’s as long as possible. In the end to fully enjoy of your purchase. Don’t fall into paranoia like some believing that your SSD has a minimum lifespan! It must also be said that, by comparison, an HDD can have more easily loss problems data and case. While the SSD is more solid, and does not afraid (too much) of shocks. Besides even when a cell is “dead”, the data is always accessible. Its speed is 6 to 8 times that of a HDD. Gourmet (पेटू) software’s such as Adobe Photoshop opens at a speed more than appreciable. Work with an SSD and you don’t you will not be able to do without it! I’m done for explanations.

Performs much like a Hard Disk but is extremely fast and also extremely expensive. These drives are being used in smaller laptops/notebook computers and on some tablet computers where you don’t require large amounts of storage space. These drives can also be useful where you need fast data transfer rates, such as for video editing, playing games and recording audio/video. These can be over 2TB, however large capacities are expensive. The average size in use is about 250GB.
