HDDs for HD video screen/gameplay capture!

Hello everyone!

I want to make a series of gameplay (and maybe screen) capture videos in 1080p and good quality. The system I have right now has about 80GB free, but with a 20min long video it easily goes down to 60GB or less. So I want to buy some new HDDs.

I am probably going to buy 2x2TB and make a RAID (mirror), so that I work with (a little more) safety. I will have more HDDs in the near future for backups. So the logic is 2x500GB (RAID) as system drives (I already have those) and 2x2TB for storage and gameplay capture.

I am concerned about 3 things:
1) price: I would like to stay below 250euros (341USD)
2) noise: I also word as an audio engineer and I record Voice Overs or other sounds in the same room, so I would like to keep noise levels to a minimum.
3) bandwidth: Is the bandwidth of a 5400 or 5900RPM HDD going to be enough for capturing HD video? I am considering low RPM for the noise issue, but if it's not going to work, then I will find another solution for the noise.

I made some quick calculations and found out that the videos I capture must run at about 18MB/s... A 2 minute video I captured is 2.16GB so:
2.16 x 1024 = 2211.84 MB / 120 secs = 18,4 MB/s

If the way I calculated that is correct and according to this article about WD Caviar Green:
"In our large file transfer tests, the disk's performance was in line with its full-speed rivals, averaging 139.8MB/s based on a write speed of 133.1MB/s and a read speed of 146.4MB/s. However, its slow spin speed makes an impact on its performance in small file transfers. Here, it averages just 47.1MB/s with a slow write speed of 37.6MB/s and a read speed of 56.6MB/s. That makes it better suited to being used as a data disk than as a system disk."
then it should work. I just want to ask if you guys know something more or have tried something similar and what results did you get, so that I don't spend my money to get something that won't suit my needs.

ps: I record 1920x1080p, 25fps, AVI, and the software gives me "low/normal/high" quality settings. In low the quality is obviously worse than normal. In normal I can actually not spot any flaws compared to what I was seeing when I recorded the footage, so I don't care about the high setting. The software I use is Mirillis Action.

1: Lots of people use them (greens) in raid but they can cause problems and the only help you'll get is : they are not intended for raid. I think you'd be fine with raid1 though I counter with asking you to consider the RED series of drives which are raid ready and don't have the early sleep issue the greens do.

2: The speed you see is the maximum speed the drive can attain which is at the outter edge. I'd recommend setting up a small partition first used solely to record to and then a large second partition for the main storage . This will guarrantee the reording has top speed. When you are done recording copy it to the main storage partition. It sounds like a 100gb partition would meet your recording needs for quite some time.

If you want more bang for your buck, look for hard drives on ebay. Lots of cheap new/good used ones there.

Also, what are the specs of the rest of your system, because that will affect the recording speed as much as the HDD will. What are you recording with?

Also, have you ever considered H.264 over AVI? I believe that H.264 takes up less space when all is said and done.

@ss202sl: Why is that?

@axehead15: My system specs:
Cpu: Intel Q6600 @2.7GHz
Ram: 4GB DDR2 5 5 5 15 1066MHz
Mobo: Asus P5E
GPU: nVidia GTX550 Ti 1GB
Windows 7 64bit

In some heavy games I experience some lag, though I know it's because of the pc specs and not the HDD. I mean, the games that run fine, without recording, run pretty fine when I record too. That's ok with me, it's something I am aware of and can work with. So the question is: If the specs don't (or didn't) get in the way, will (or would) a 5400 RPM drive and a 7200 one, perform equally for gameplay capture?

The software I use does not give me the option to record in H.264 1080p, but only up to 720p. I guess that is to avoid overloading the CPU, because of the bigger encoding work there is to be done when converting to H.264. It gives me the option to convert and delete the original later though, so that won't be much of a problem.

Edit: What about the WD AV-GP Drives?

- actually in thinking about it I would record to the 100gb, when done, copy (not move) it to the 500gb (which gives you a backup copy left on the 100gb) and then edit with the destination being the 900gb (will actually 831 after formatting). When the edit is uploaded & backed up, clear the file from the 100 & 500.

Green drives sometimes have been known to cause issues with their sleep cycles as well. I would just use a 7200 RPM HDD. The WD Blues work fine, and they are fairly cheap. You can usually find a good deal on Newegg for new ones, or on ebay for refurbished/new/used ones.

I would happily go for Blue (which seem to be more universal) but unfortunately there is no 2TB model. I won't consider green ones because appart from performance during capturing, I want to use them generally for storage.

Now that Green are out of the way, I am still a bit worried about the RPMs. The RED ones seem to run @ 5400.
@poapatim: Can i set the partition for recording to be on the outer edge to achieve maximum write speed?

Maybe I should go for seagate? I wish WD had a 2TB 7200 Blue model... Maybe I should give a few extra bucks and get 2 Se?

I think I 'll go for 2x2TB REDs and in case they don't work as good as my current drive, I 'll just create a small partition in my current drive (7200RPM) which is tested and working perfectly and then copy the files I need to the 2TB HDD RAID. It seems like a safe/best option, considering price, noise and performance. Thank you all!

@popatim: I am not sure if that is what you meant I got a little confused by your post, but at least that idea came when I re-read it.

So as I see it you will have two 500GB drives in raid1 and two 2Tb drives in raid 1. The main idea here it to avoid forcing one drive to both read and write which is why having a seperate recording drive helps alot.

I would partition the 2tb, as mentioned, into two. First create a small recording partition, lets call it R: for recordings. Partitions are created on the drive from the outside in so creating the small one first insures it gets the fastest part of the drive. The size is up to you.

After that's created partition the rest of the drive. Lets call it D: for data.

Now when you are playing your game from the 500 you can record to R: and you wont have to worry about the 2tb trying to read and write at the same time, which kills its speed btw.

When you are done recording copy it from R: and to C: (copying insures that you have a backup copy of the recording still on the R: drive)

When editing - Edit the C: copy of the recording and setup your editing software to save to D:
You will find that this setup, reading from one drive and writing to another, will improve your rendering times (saving your edits)

After you make sure your edited video on D: drive is good to go (I would) make a backup of it (DVD is fine) and maybe burn the original recording too. Then you can delete the original recording from both C: and R:

I'm not sure how important these recordings and edited videos are to you so if its not very then you don't have to back them up but keep in mind that when the 2tb drive fails everything that was on D: and R: dies with it too.

I don't seem to be able to reselect the best answer (I was in a bit of hurry yesterday), but this makes it all clear for sure! Thanks a lot, that was very detailed. :)
