Hi everyone.. just want to hear your opinion and suggestion concerning my current SSD and HDD raid configuration. I am using a Dell T5600 workstation for my workplace (please see specs screenshot). It arrived pre-configured already from Dell and I never tweaked anything. It's been 2 years old and so far, it's running well.
Recently, I decided to do a little hard disk speed test (since I also plan to build my own personal PC with SSD+HDD). As shown in my specs, I have two storage drives. 1st- Intel SSD 250GB, used as main system and current projects drive, and the 2nd one is a 1TB as files archive drive.
CrystalDiskMark's data shows that my SSD is a clear winner.
But for practical test comparison, I used two of my biggest & slowest sketchup files, first a 150MB file. Next is a 350MB file. The test files was put on SSD and HDD respectively. How I tested: 1. I opened it (timer start), 2. Save as to a new file afterwards (timer starts).
To my Surprise, the results are almost identical, and HDD even won a few seconds when testing the 350MB file. This changed the direction of my query, towards the raid configuration. Honestly, I don't know why Dell preconfigured it in this manner or why put a PCI controller (I assume it being a workstation build standard practice). Sadly, I can't find enough info of my harddisk's brand and specs except that it's on raid. In bios- I see these in first boot sequence: "(BUS 02 DEV 00) PCI RAID ADADPTER)"
My questions:
- Do I need to change anything with the Raid settings to improve my SSD perfomance?
- Is the result above indicates that my SATA HDD is performing faster than average HDD, and on par with SSD because of the PCI raid adapter? (I don't mind if this is the case, I regard it as good setup)
- Or is my SSD slowing down, and functioning like a regular HDD because of raid set up?
Thanks so much for looking. Cheers!
