Test what? Results for what? What kind of usage? What file server? It all depends on what data you store where and how much is it accessed. Just adding an SSD is not going to change anything unless you make it usable in some way.

Test result for file transfer speed over 1gb lan, usage fore large files server,

I assume you're new to Enterprise server networking?

 

What is the SSD doing? How is it configured? What Operating System is the server using?

 

Basically just adding an SSD to your server doesn't magically make file transfers to your Network Share faster. You have to configure it in such a way as to take advantage of the SSD in some capacity (As a two tier storage array, or as a cache, etc).

 

However, in reality, any decent HDD can sustain 1Gbps networking at full speed. 1Gbps network is only ~125 MB/s. An SSD might help if you are transferring thousands of tiny files, but if you're working with larger files, you'll see little performance difference.


For Sale (lots of stuff):

* Crucial M4 128GB SSD (Primary) * Hitachi 500GB HDD (Secondary) *

* Gigabyte HD 7950 WF3 * SATA Blu-Ray Writer * Logitech g710+ * Windows 10 Pro x64 *

There are four metrics used to determine the best choice: Size / Transfer-rate / IOPs / Seek Time. You have to pick which is most important to you, as it will not only tell you Spinner or SSD, but which grade of SSD you should buy. If your only purpose is to transfer at 120/mbyte/s then anything you buy will be fine.

 

If you want to run virtual machines off a shared datastore, then a consumer grade SSD that can handle ~80,000IOPs will be fine (for 10-20vms depending on what they are).

If you're running an enterprise SQL server with heavy traffic then are SSDs designed for write-intensive operations (extremely expensive).
