Hello
I purchased dxtory a few months back and never really used it that much because my studies took over, my pc monitor broke and I didn't have a job so I couldn't purchase a new one until now. I now have a 1920x1080p monitor (my last one was 720p) and I was wondering if my hdd would be able to record in the new resolution. I also need to buy a new hdd to store my recordings so I was looking at the seagate barracuda 2tb 7200rpm sata 6 http://www.amazon.co.uk/dp/B006H32Q3S (http://www.amazon.co.uk/dp/B006H32Q3S)
I am unsure what speeds that hdd would get so if anyone knows it would be much appreciated.
I saw how you calculate the hdd speed required.
QuoteRGB24 YUV24: Width x Height x 3 x fps = bitrate (byte/sec)
YUV420： Width x Height x 3 / 2 x fps = bitrate (byte/sec)
YUV410： Width x Height x 9 / 8 x fps = bitrate (byte/sec)
So It would be
1920 x 1080 x 3 x 30 = 186624000b/s = 177.978515625mb/sBecause I am unsure of the speeds that the hdd can achieve I am not sure if it would be fast enough to record at that resolution. I then remembered that dxtory has "Distribution HDD Writing" that reduces the speed that each hdd needs so if I were to buy 2 of them would that feature make them able to record at that resolution.
If nobody knows the answer I will just buy the drives anyway and test for myself.
Thanks In advance.
Matt.
Update. I read http://www.tomshardware.com/charts/hdd-charts-2012/-05-Write-Throughput-Maximum-h2benchw-3.16,Marque_fbrandx42,2903.html (http://www.tomshardware.com/charts/hdd-charts-2012/-05-Write-Throughput-Maximum-h2benchw-3.16,Marque_fbrandx42,2903.html) and the barracuda 2tb HDD gets a maximum of 203.59mb/s write but the average is only 153.50mb/s. I hope this helps
PC Specs (If it helps)
AMD Phoenom II x6
4gb 1600 ram
2tb 7200 sata iii boot drive
asus 6770 graphics card (so I get over 40fps on almost every game I play)
650w psu
Sorry about really long text.
My recording disk maxes out roughly at 120MB/s, avg. being around 112MB/s and I do 1080p 30fps recording just fine. A codec with lossless/near-lossless compression helps alot.
For instance, Lagarith lossless and Ut Video Codec both compress quite nicely and are pretty fast, if I'd have to take a guess theyd probably take 80-100MB/s pretty much all the time, depending are you using RGB (lossless) or YUV422 (lossy, but not much).

Thanks. I will order one of those hdds now.
Just use Lagarith in YV12 and you can cap at 60fps easily. Capturing above YV12 is pointless as youtube won't even process content which is above 4:2:0. For BF3 capturing at 30fps results in bitrates of about 250Mbps, or 30MBps.
i'm looking for a new 2TB HDD,
can anyone help me to find the best one?
It's important to know the difference between Byte (B) and Bit (b): 1B = 8b
The formula is for the worst-case, the average-case is (much) lower.
For me, 1080p@30fps YUV420 with MagicYUV 1.2 is usually at around 25-35MB/s (or 200-280Mb/s). Pretty much any current harddrive can handle that.

That depends on your price range. I personally use Western Digital and had bad experiences with Seagate.
i found this article on google
http://www.deskdecode.com/top-best-2tb-hard-disk-drive-monthly-updated/ (http://www.deskdecode.com/top-best-2tb-hard-disk-drive-monthly-updated/)
and they suggest me to buy Toshiba Desktop DT01ACA200.
how about that?

This is simply not true. Youtube will accept 4:2:2 and 4:4:4 video, including video encoded to the Apple ProRes codec with 4:4:4 sampling. I'm pretty sure YouTube's encoder samples it down to 4:2:0 (simply because it doesn't make sense for them to stream 4:4:4 video except for business partners), but I'm not sure how to find out.
Regardless, encoding games in a 4:4:4 or RGB format is fairly important if someone is doing editing work on the video, especially if they're going to do any chroma keying.
