Is it a good drive for a cache disk?

 

Dan

1TB is pretty huge for a cache drive. Will you need that much space in a single day? When I'm moving to the server it's always under 50GB in a day, so I could get away with a much smaller cache drive.

based On my needs here

http://lime-technology.com/forum/index.php?topic=47701.0

 

One of my needs is

2- Have a shares to expand the programs Installation/running disk for apps that are not use daily on the 3 computers: Not sure of that one

 

Let me explain.

I have all SSD in my 3 PC

Main PC 240GB evo 840 SSD + secondary a crash 2Tb disk

HTPC 64Gb crucial SSD + secondary 1 TB HD

Lap top 120GB SSD No secondary

 

As far I lost the secondary drive on my main PC I lost Programs/apps that were install on it. I did backuped files(pictures and documents) on a small WD My Booklive nas

 

So I wants to get rig of all the secondary HD in each PC.

So the programs that were used to be install on the secondary drive would be now install on the cache disk on unraid!

 

Note that is not for OS but only for apps/program that are not used very often.

 

So I was thinking of that:

 

1TB ssd

3x 200GB share for programs installation for every computer total 600GB

4x 50GB users share for document Total 200GB

100GB for use in VM and plex and others

the rest for the cache disk

 

My question is does the performance of the Shared programs will be fast enough to be usable or I should keep the secondary drive architecture? Or add SSD in the computer itself and buy more smallest SSD?

 

Any comments regarding my solutions is welcome as far I'm a newbie with unraid.

I just have 2 drive right now with a 30 days trial test.

 

Thanks

If the SSD can read at 500MB/s that will likely be higher than your network can deliver. I have never been able to get anything remotely close to those numbers and my server is a few feet from my PC.

 

Do you have any way to test this idea before buying the SSD?

I just got a kingston  240gb for testing.

 

If my Math are correct.

A normal HD 7200 rpm is about 100MB/s write Speed so about 900Mb/s

Since the SSD is in the Unraid server the bottleneck is the network (1000Mbs) not the SSD

I should have similar performance with the SSD in Unraid vs an 7200rpm HD in the PC!?

 

I will make some test

 

Thanks

 

Dan

Theory doesn't always work in the real world Best is to test your actual network.

I did some test and seem very unusable because of the variation on the lan.

so I will keep my 240GB ssd for the cache.

 

Thanks

 

Dan

Glad to help
