Since you are dealing with a large amount of storage with movies and then having to transfer that data when you copy/move and play it, you should go for performance. If the data is just for archival backups, go for the Green. But since you will be access this drive often.... playing it, encoding, backups, etc.... go for the Black.
AND... dont stop at 1TB.... go for the 2TB Black. By the way, this particular model - WD2001FASS Reason is that this hdd is FASTER than even the Velociraptor 300Gb drive.
Thanks, glad you got what I was asking. I've noticed with computer components and frankly almost all hardware you can't get efficiency and performance and I would hate to have poor performance when playing back video.
Yeah, I was leaning towards the black myself, just because I have been so pleased with the two I already have, but thanks for pointing out the higher capacity model I was unaware that there was one.
...I would hate to have poor performance when playing back video.....
With your system, I think you really have ZERO need to worry about the difference in performance between the two drive types while actually playing the videos.
Your main performance issue would be transfer rates while loading to the drive, and even then I think you're probably talking differences of less than a minute rather than minutes in initially transferring an 8gb set of files to the drive. Larger files would of course take a bit longer. To me, one-off loading of large files is just a personal preference and cost issue.
If I were going to be concerned about it, I'd be more concerned with determining the optimal cluster-size allocation setting for the drive given your application will be for movies. That can make an overwhelming difference in actual MB/sec transfer rates. The default allocation in my experience is generally a performance killer. You'd need to experiment with different allocations with a file or two (To do the comparisons I'd set up a small test partition because you will be formatting at least several times between tests). Testing to optimize is needed because the drive, the interface, the cache, etc. can make a difference in baseline performance.
Same for your other drives as well, by the way.
edit to add:
And, cluster-size allocation will also have a major impact on the initial file loading transfer times as well...likely more of an overall impact than those two drive types performance differences.
edit: "8gb file" to "8gb set of files"
edit to add:
And of course, overall transfer rates will depend somewhat on where on the drive a given partition is physically located. Historically, the primary partition has also been the fastest, but this will likely change with new technologies. I assume under your intended application fragmentation is a virtual non-issue.
Thanks for the advice with tweaking the drives, I will look into that.
As for the power supply, I have had it for about a month and have had no issues with it what so ever. This is my first build and the only examples of computers I have to compare it to are 8+ year old gateway and my parent's 4 year old PC so take my opinion with a grain of salt due to my lack of suitable hardware to compare it to.
So far the noise has been minimal, I can hear a slight hum coming from the PC but in comparison to the noise the video card makes its nothing. I haven't had any other issues with it either.
with the Black, you are given the rpm within the specs becuase this is a fix item... in this case 7200rpm
BUT.... with the GREEN...... there is no given rpm within the specs.... because the rpm varies from 5400rpm on upwards to 7200rpm.... but its goal is to stay at the lower rate because its priority is power savings....
I am new to this, how do I go about changing cluster-size allocation... is that a setting in my OS (windows 7) or an option in my BIOS.
Looks like the caviar black 2tb will be the winner.
Not in Bios with a non-raid hdd. After connecting the hdd to the system... boot up to desktop. Go in to computer management and then in Disk management. Choose the new drive. Right click and do a format. There is a point prior to actually formating.... there is a question able cluster size. Default is 4k. You can choose sizes like 8K, 16k, 32k, 64k, 128k, and so forth......
this is from my old feeble old memory cells....... hopefully it is correct...
