Performace HDDs in RAID 0 for high resolution video capturing

Hey guys,
I am planing to upgrade my current storage configuration which is currently for capturing gameplay videos a Seagate Barracuda 7200.12 ST31000528AS 1TB (DiskMarkx64: 120 MB/s read, 115 MB/s write).

I can only capture around 45 FPS at 1440p. But due to my GPU config, I could capture at least 90 FPS, if I had a storage config that would not bottleneck in write performance.

I thought about SSDs in RAID 0 or caching with an SSD but due to my limitation in budget, which is a maximum of 150 € so about 120 Pounds, nether of those to options are applicable.

So I found that two performance HDDs in RAID 0 could be the solution. I am now comparing the brandnew Seagate Barracuda like this one

and the newer WD Blacks like this one http://www.aria.co.uk/Products/Storage/Hard+Drives/3.5+Inch+SATA+Drives/640GB+-+1TB/1TB+Western+Digital+Caviar+Black+WD1002FAEX+3.5%22+SATA+III+Hard+Drive+-+HDD+?productId=40242

I am also still not quite sure about the capacity, should be at least 1 TB per drive.

Thanks

Dude because your GPU plays at 90FPS when you start recording the recorded FPS does drop....

Even does on a Titan mate its normal.

I m aware of that fact, but when I record to my RAM Disk which is obviously not big enough but is not limited performance wise, I can record at almost 100FPS in Battlefield 3 on Ultra. (dual GTX 680s 4GB )

Id honestly think about an SSD mate.

I thought that with writespeeds of 120 MB/s I can record 45 FPS.
So if I want to record double FPS (90) the solution would be to have double the writespeeds (240 MB/s), wouldnt it?
And two performance HDDs can deliver that speed, right?
So why spend lots more money for an SSD which at the end of the day will not be big enough, considering that I am recording 2-3 hours per day. That amount of data is just too big for any SSD I can afford, even for a 480 GB one...

Well there's more risk of data loss with the HDD's. If you just record, then play with the footage and send it on its way, then i guess there's no reason why you cant use HDD's. If you keep all your footage on there then id certainly take a look at the SSD's

After loosing 2TB of data I've switched to SSD and gone with a raid z for HDD storage. If the data is important to you don't do a raid 0 with mechanical drives.

2 drives doesnt mean double the speed.

After recording, I edit the video, upload it and empty the drive afterwards, so not a big risk.
And yes, 2 drives doesnt mean double the performance, but when one new drive can write 180 MB/s, two drives schould easily do the trick...
I just still dont know which HDDs to choose...

You can get a 240MB ssd now that is 500MB/s+ for less than 150.

I certainly wouldnt be putting noisey ass mechanicals in my rig if it was me.

I don't really know what i'm on about in terms of performance, but if 2 mechanicals cant hack it, could you not just use 1 large HDD and get a SSD for caching?

240 MB are filled up in about 45 minutes of recording.

I am running a quiet rig and that is why I wanted to know which HDD perform well and are not noisy ass ones.

With caching the SSD would be filled up pretty soon, due to the bottleneck of HDD write performance, wouldnt it?

Again... "I don't really know what i'm on about in terms of performance".
I'm just throwing ideas around mate.

I am just telling about the performance.
And I also thought about solutions with SSD, I only doubt that they would work for my particular situation...

I think I might just get two of those and if it doesnt work, Ill just send 'em back.

Ill let you know...

So I setup the two Seagate Barracuda 7200.14 2TB ST2000DM001 HDDs in Raid 0 in the bios with the intel storage controller. I had to plug my SSDs running in AHCI in the AsMedia controlled sata ports which increased boot time to about 20 sec with Win8, but my system is almost 24/7 on anyways and the performace I get out of this RAID 0 is just freaking amazing, IMHO.



That is almost double the performace of a single drive that benchmarks online show, especially in ATTO.

Yes they are only filled to 4 %, and yes performance will decrease when the drives get full of data, BUT now I can record up to 140 FPS in 1440p. Well at least games like Counterstirke, in BF3 my 680 outputs around 75-80 FPS which is totally fine for the gameplay videos I am making out of the footage, considering Youtube using a 29.73 FPS codec.

And they are really not "noisey ass mechanicals". They are quiet, not silent - of course due to moving parts etc. - but I cant hear them over my Noiseblocker eLoop fans at 1000 rpm that sound to me very similar to Noctua NF-F12 at 7V.

So, brilliant drives, IMHO.
