More information about the internal structure of SSD


SSD or Solid state drive - it's such a hard disk, which as a carrier of information are the chip NAND, and not magnetized plate, as in the conventional HDD (Hard Disk Drive).That is, it has no read heads, spindle and so on. N. It is has no mechanical components.

SSD consists of several parts, assembled and functioning harmoniously together.The first and most important part is the controller.It controls the operation of the drive and is a sort of "heart" of the device.The second part - a set of NAND flash-memory, where it stores all recorded information.

Since the controller controls entirely all the processes of reading and writing t
o the SSD drive, and performance of the device depends on the part.In modern SSD controllers are used, in which 4 to 10 channels for parallel connection of memory chips.The more channels, the higher the speed of data recording.

More from SSD available in its own cache memory.However, she is not used to increase the speed of reading, as it is made from the HDD, as a temporary data storage.Today, there are the SSD 128, 256 and 512 MB of cache memory on board.What will be specifically used for the memory SSD, it depends on the volume.The larger the volume, the larger the cache, but the price is then much higher.

What will replace the HDD to the SSD


If you replace an outdated today HDD to a new and modern SSD, the notebook user will receive a significant reduction in time load Windows.The growth rate will be around 60% in relation to the conventional hard drive.Start working much faster all Apps.For example, Windows 7 is fully loaded on a laptop with SSD's in about 15 seconds after switching on.

notebook will operate on battery power for much longer, if it is installed SSD instead of HDD.In addition, solid-state drive (SSD) due to lack of mechanical components, able to withstand more mechanical overload.

replacement HDD to SSD


Since all modern SSD made in the form of 2.5 inches, replace the standard notebook HDD is not be easy, because it has the same dimensions.First of all, turn off the laptop and remove the battery from it.So you completely disconnect the device.

Now look carefully where the HDD.All laptops are usually its location is indicated with a special icon.After determining the location, remove the screws and remove the cover.Usually HDD is optional in a special basket and fastened to it with screws, unscrew them too.

Remove the HDD from a special basket, instead install SSD and repeat the procedure in reverse.Tighten all screws, replace all covers.Try to carefully remember which screws where, lest confusion.Replace the battery and charger.Be sure to install the SSD in the new Windows, it is not necessary to transfer, copy or clone the old system from the HDD.Since old operating system was put on the HDD, and the service it started to work with this device.On the SSD, these services not only did not accelerate, but can also contribute to a more rapid deterioration of the disc.

Now, when the notebook is in an assembled state, turn it on and press F2 several times to get into the BIOS.It is necessary to make a special setting for SSD.Find the Advansed / Sata Configuration.Set the mode AHCI.In the Boot Priorities set the first boot drive or USB CD / DVD-drive, looking where going to install Windows.Save the settings by pressing F10, restart the laptop and start the further installation.Do not forget when choosing a system disk to specify precisely the new SSD.
