We go to SSD?

Internal SSD 240GB, which can be used as a storage drive in place of or in complement of your current hard drive data (very quick access to data, energy saving because no rotation as on a traditional hard drive).

But who will be ideally used as a hard disk boot, allowing extremely fast computer operation (Quick Start, Quick Launch applications) with increased energy efficiency.
This requires a bit more knowledge and handling: do a cloning its current boot drive on this one before the swap (and possibly keep the old disk as data after formatting if the transfer went well)
Neophytes in IT, it's not for you, but those who do not hesitate to lay hands "on dirty" will find all the information and tools on the net. Windows 8 users, your task will be made more difficult (it's beautiful the "progress") but solutions exist (for me, at the time, it is rather passed by eradicating win8, but everyone's choices ).

The size of the hard drive might seem a little narrow for a C drive, but at the cost of SSD, few would have hard drives larger capacity 240GB and is even pretty good!
On Windows, if you do not yet had the habit (though essential for many reasons), you will now avoid storing or install everything and anything on your boot drive (the base being already to have a 2nd hard drive that will be devoted to data, and possibly installing some programs too "heavy" or for which the speed of execution you will matter).

Even him about the disc, no complaints this time.
It is obviously quiet and fast compared to a conventional dd, and also very light.
In order to assess its speed compared to others in its class, it would make quantitative test, which exist in the press. In my personal use, I think in any case the same accabit other SSD that I used.

The anxiety about the SSD is still the life, but it seems theoretically correct given the average life of a PC and nothing can say more now. For your important data, make copies on multiple media remains the rule anyway.
Sandisk is also a mark with a rather good reputation, and the disk is guaranteed for 3 years. Download sandisk management utility (Dashboard SanDisk SSD) to keep an eye on your drive, the "usury", functioning, and to enable its possible updates.

Total: SSD that brings well-known advantages over traditional hard drives, which in its category seems to have very good performance for a fair price too. Reliability assess over time.
