Anyone can tell me if there is an increase of working transfer or networking speed on NASLIte-M2 if I use 2 GB of Ram instead of 1 GB ??
If yes how much in percentage ??

Regards - Michele.

Just really effects the write behind caching. If you got it, use it. If not then save your money.

So a very little percentage in power processing gain ... which are the real effects of write behind cache ??

When you write to the NL server it is actually writing to the cache. The server then writes to the drives as fast as the drives can take it. Obviously writing to solid state memory is going to be far faster than to a mechanical drive. What this means to you is that a write of a file or files that are under the cache size are written at wire speed and/or the limit of the processor of the machine up to a point. Say you have a 100MB file to write and you have about 980MB of cache, the write will finish as fast as the network can move the data to the server. In the case of GigE that would be in the 70-80MB/sec range on in other words, about 1.3 seconds. Where this will really shine in in multiple clients writing to the server at the same time. In this case the random writes will kill the performance and drag just about any drive other than a solid state drive to a crawl. Even the fastest of SCSI, SAS, and FC-AL drives on high end controllers will help little in this case, cache makes all the difference in the world.

Fantastic ... you're really a great "professor" ... many thanks !!!

If I would like to Test (real) write/transfer speed from Windows Client to my NASLite-M2, what kind of (free) software should I use ??

Most people seem to use Diskwriggler and you can DL it here.

(use the XP version and run it in a cmd window with the parameters that you can see others using (Mikeivers are a good place to start))
