Intel G530 NAS performance - part 1

As you have read here, I have recently installed my new home NAS. I think it's a good idea to share the performance I get in order to allow other NAS-owners to compare their results. My build is based on the following parts:
  • Intel Celeron G530 processor undercloked to 1.6 GHz
  • 8 GB G.Skill Ripjaws DDR3 underclocked to 1066 MHz 
  • MSI Z68 motherboard with integrated Gigabit NIC
  • Crucial M4 64GB SSD
  • 2TB Western Digital Caviar Green WD20EARS 5400 RPM
  • 500GB Western Digital WD5000AAKS 7200 RPM
  • 350 GB Samsung HM320JI 5400 RPM
  • OS: Windows 2012 Server
In this first test I have used CrystalDiskMark 3.0.2 to test raw sequential read and write performance over a gigabit network.

From my test machine I mounted the Crucial M4 SSD (with letter Z:) and the 2TB WD Caviar Green (with letter Y:). This PC is networked with 10 meters long Cat 5e network cables.

Here's the results I got reading and writing 500 MB of sequential data for the Caviar 5400 RPM HDD:

* MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s]

Sequential Read :    36.213 MB/s
Sequential Write :    54.934 MB/s

Let's see a graphic compating those results:

My NAS performance compared to gigabit network and SATA speed
As you can see there is clear difference in performance between an SSD and a 'legacy' HDD. While the performance of the SSD is limited only by the Gigabit network (90 MB/s), the mechanical HDD is limited by its capacity to sustain 64-Kb reads and writes.

That's all for this first post on the performance of my NAS. I'll delve into more detailed benchmarks in forthcoming posts and I'll also test these hard drives without using the network. I'all also see how my configuration can be tuned to deliver faster results if possible. In the meantime, do not hesitate to share your own NAS results but remember to detail your build configuration for other to be able to compare!

  1. Can you do some speed test with bitlocker activated?

    I want to build a nas with the same processor and would be curious to see how it handles encryption.

    Thanks!
