Hi All,
I just bought me some new storage (3X3TB WD disks) because i wanted 1 central place for all my data (for all the devices in my network).
I'm currently running a 5 RAID array on my pc
(later the RAID5 setup wil be moved or recreated on my Windows home server 2011, but for the moment the WHS is still running on an old motherboard that can only use 750GB of each 3TB drive
So for now, i'm testing it on my desktop.
Desktop specs:
Intel Extreme DP67BG Motherboard
I7 2600k sandy bridge @ 3,6GhZ
16GB of DDR memory
1 x OCZ-VERTEX 3 SSD 120GB on sata 6gb/s ports
3 X 3000GB Western Digital WD30EZRX (in RAID 5, configured at boot with intel raid tool) on sata 3gb/s ports
At first everything was working really great, amazing read/write speeds.
And i mean really insane write speeds (copying 1GB from my SSD to the rAID5 array beneath a second)
But then I realized only the first +-1,5GB writes insanely fast to the RAID5 array, afterwards the speed drops to... +-40MB/s
I have no idea what's causing this?
Can somebody explain to me?
I've also made a screen capture so you can exactly see what happens.
Movie can be found here
Please help me out! All information is welcome!
It would be really great to keep those insane write speeds for "unlimited" amounts of data...
Thanks in advance
