SSD winchester

Question

Solid State Drives

If you do not take into account the price, how is it even better / worse than usual?
Familiar people scare with a limited amount of writing / reading, but how is it really? How long will such a hard drive last on a working laptop?

Answer 1

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

Answer 2

I will add a few points to the previous answer:
1. The advantage will be in all read and write modes, but the most noticeable, as already mentioned, is in random reading, due to the fact that the SSD does not need to move heads to the desired sector on the disk each time. At the same time, there is a significant advantage in reading small fragments of files - in the region of 512-1024 bytes.
2. It is by this indicator (reading small fragments) that many SSDs differ from each other. In those. characteristics usually write the maximum reading speed, which is achieved only when reading relatively large fragments (from 128 kb and above). At the same time, as also mentioned above, many frequently used files are just small, which leads to the fact that two SSDs with almost the same read speed can behave very differently in real life.
3. There are really few statistics on the lifespan, however, manufacturers' data allow us to conclude that it will last quite a long time. I don’t remember the exact numbers, but it seems that with daily recording in 20 GB, SSDs will be guaranteed to work for about 5 years, i.e. will definitely live up to their own moral obsolescence.
4. Over time, however, SSDs can noticeably degrade in performance. To prevent this from happening, you need to make sure that either TRIM, which is supported by the operating system, or the built-in garbage collection of the controller, if any, works properly.
5. It makes no sense to compare modern 2.5 SSDs with 8-16 GB drives that were installed in the first netbooks. Those disks are much less technologically advanced, work much slower, and are generally obsolete.
6. Finally, subjectively, in my experience, there is no point in chasing speed, trying to get the fastest SSD. In my opinion, for a regular laptop, a speed of 100-150 MB / s of reading is enough, then other components of the system will be the bottleneck.
Ask if you have any questions. I wanted to write an article about SSD on Habr, but my hands never reached ...

Answer 3

Better read speed, sometimes even write speed.
If everything is set up correctly - more than three years. If you put a journaled FS, then it can die in a year.

Answer 4

The biggest advantage is in random reading and, to a slightly lesser extent, in arbitrary writing. The difference with 7200rpm hard is striking.
Simply put, all software that has a bunch of configs, a cache consisting of small files, etc. just flies. First of all, this concerns the Windows itself. Visual Studio, Photoshop, many games also win big.
There are not enough statistics for the time being. I've had a first generation Intel on my desktop for two years now.
