If you do not take into account the price, than it's even better/worse than usual?
Friends fear a limited number of read/write, but really? How much time will last this Winchester on work laptop?

From personal experience — on a netbook Acer Aspire One such winch 8 GB worked for a year and a half with the operation of an average of 3 hours a day.

To the previous answer add a few points:
1. The advantage is in all modes read and write, but the most notable, as already stated, in random reading, due to the fact that SSDS do not need every time to move the head to the desired sector on the disk. At the same time, a significant advantage is in reading small file fragments — in the region of 512-1024 bytes.
\r
2. According to this indicator (read small fragments) differ in a SSD. In characteristics usually written maximum read speed, which is achieved only when reading relatively large blocks (128KB and above). At the same time, as also mentioned above, a frequently used files just fine, which leads to the fact that two SSDS with almost identical read speed can behave very differently in real life.
\r
3. In the lifetime statistics is really small, however, these manufacturers enable us to conclude that enough long enough. Exact figures can not remember, but it seems to be in the daily record 20Gb SSD are guaranteed to work for about 5 years, i.e. just live up to his own obsolescence.
\r
4. Over time, however, the SSD may significantly decrease performance. To avoid this, you need to follow in order to work properly either TRIM support which is provided by the operating system or built-in garbage collection controller, if any.
\r
5. Compared to the present 2.5 SSDS with 8-16 GB drives that were installed in the first netbooks, makes no sense. Those discs are much less technologically advanced work much slower and generally has long been obsolete.
\r
6. Finally, subjectively, in my experience it makes no sense to chase the speed, trying to take the fastest SSD. In my opinion for the average laptop will get enough speed to 100-150 MB/s reading, then the bottleneck will have other system components.
\r
Ask if there are questions. Wanted habré article about SSD write, but his hands never came...

Better reading speed, sometimes even with the write speed.
If properly configured — more than three years. If you put jurnalismul FS, then maybe a year to die.

The biggest advantage in random read, and to a lesser extent, in random write. The difference with a 7200rpm hard striking.
\r
Simply put, all the software which has a bunch of configs, cache consisting of small files, etc. just flies. First of all it concerns the Windows. Visual Studio, photoshop, many games, too seriously to win.
\r
In terms of statistics is not enough. I have a Intel first-generation works on the desktop for two years.
