Storage and Performance - Post Your Results!

[msobon]

So I gueess this is an offtopic but we're all storage users!!

 

I did some benchmarks on my current setups as I'm moving to unraid (need for more cost affective storage) but i'm also perfomance junkie and jsut wondering what people are getting on their drives. below are some benches I've run:

 

You Can get the Benchmark tool here:

OCZ 120GB Revodrive PCI-Express SSD (basically two SSD's on a Raid 0)

 

Two 1TB Western Digital Caviar Black 7200 RPM 32MB in Windows Mirror

 

Promise Supertrack 8350 with 4x Seagate 1.5TB 7200RPM and 4x WD 1.5TB Green 5900RPM in a Raid 6 config

(I ordered wrong drives and didn't bother exchanging hence the miss match, must hinder the potential for better performance but still gives good results)

Drool-worthy results.  Here's my crude benchmarks in using two different budget SSDs as cache drives in unRAID (just as straight drives, no RAID 0):

 

SSDs as cache

 

The gist of it is that the fastest speed I saw was around 73 MB/s, which is only about 10 MB/s faster than a 7200 rpm drive.  Not terribly inspiring.  My conclusion was that SSDs as cache drives are not worth it for the performance benefits, but still may be worth it for the low power and lack of spin-up lag.

I think if we all had a common set of rules it would make for a fun experiment. You know.

 

Common testing app.

Common File size

 

Real world testing to me would be testing across the network since most of us already have our drives installed.

I'm attaching the tool I used, it's mainly for SSD's but works on normal drives too.

Umm, who uses SSD's with unRAID? having SSD speds is unrealistic. Of course they are going to be super fast, very fast. Seeing speed tests with real world setups would be more constructive in my opinion.

People using an SSD IN there array is not a very good/constructive use for one.  When I rebuild my server in a new case in the next couple of months I plan on using an SSD for a VMWare install.

I use CrystalDiskMark (open source project at sourceforge).

you can configure the loop count and the file size.
