Got my new controller and HDs!

[SilverMK3]

So I got sick of my maintaining my file server and dealing with the associated network issues at home. Instead I've opted to add some nearline storage to my main machine and scrap my server altogether.

I just received the first shipment of parts today - I'm still missing a couple of hard drives, but here's what I ordered:

- Intel SRCSATAWB hardware RAID controller
- 1x Western Digital WD6400AAKS "Blue" 640GB drive for my OS
- 4x Samsung F1 HE753LJ "RAID Class" 750GB hard drives for RAID5


Here's a screenshot of my old array's performance (4x320GB in RAID5 on a Highpoint RR1740). It was severely limited by being on a PCI bus:





Here's my 150GB WD Raptor's performance, its kind of disappointing now:

The Raptor is gonna be sold and replaced by this new WD 640GB Blue:

Here's a single Samsung HE753LJ on the Intel SRCSATAWB controller:

Here's 2 of the 4 Samsung HE753LJ's in RAID0 on the Intel controller:

I've only received 2 of the 4 drives so far, I should get the rest tomorrow or the day after. Any ideas what I should hope to see for performance in RAID5?

I doubt you're being limited by the bus, as the controller card is PCIe 4x, which can have a throughput much greater than your benchmark results.

Check to see if write caching is enabled; being a rebranded LSI card, it may be conservative in its data protection and prevent you from enabling it without a BBU.

That first bench is from my old Highpoint 1740 controller, it was just regular 33MHz PCI.

You did bring up a good point about write caching though, I enabled it on my Intel controller and it made a difference:

Here it is with 4 x Samsung F1 RAID 750GB HE753LJ drives in RAID 5
