Supermicro X9DRD-IF onboard raid opinion
So , I was planning to configure this mobo which has onboard raid 0 1 1+0 facility , In my opinion onboard raid for 4x SSD drives should hit the marks of 2 GB/s I/O , similar to RAID CARD although i think onboard raid would not put load on CPU + mobo doesnt have to contact the raid card on a pci slot making the stuff even faster .
But what do you guys think ?
will be using 64 gigs of ram +2x E5-2620

You're probably right. However, I personally prefer to use LSI/Adaptec cards as you can pack more drives with them. Just imagine the I/O when you have 6x 900 GB SSD on a LSI Card w/ Cachevault add-on.
Also +1 on using E5-2620's
Yea planning to provision a few under this configuration
2xE5-2620
64GB RAM
4x512GB Samsung EVO pro SSD
OnBoard RAID10
125 IPv4
10TB @ 1GBPS
HostDime DC Orlando FL USA
Free OS reloads
@ $300/m
I wonder if the price is good compared to market
Umm... How exactly do you think the onboard controller communicates with the rest of the system then?
Onboard raid will be slower than a decent raid card.
will try to run a benchmark on it after my first build then will compare it with a lsi raid card variation
On board will be slower than the add on raid card.
Also do you have a spare motherboard/card on hand for the systems should one take a dump and you need to recover the data?
Ofc spare parts will be available for immediate replacement including drives will stock on WD's blacks and Samsung evos
Nope. You'd be lucky if you get something over 500MB/sec
I guess @serverian is right waiting for your results though
@serverian Lets see , even im not sure what kind of I/O speed i'll be experiencing , it is a SATA III RAID , the onboard raid you mentioned is SATA II which is limited to 500 mb/s
No, he's right. You'll find out soon
You are running RAID-10, on-board controller vs addon controller will make no real difference.
Plus an addon controller is introducing a SPoF - Single Point of Failure -- for no reason.
You also lose TRIM/garbage clean up by using raid cards -- which actually means DECREASED PERFORMANCE.
Good price with that overall expensive hardware config.
