I am looking at completely upgrading my storage solutions for my desktop.
I do a lot of recording HD videos (1080p) and i am looking for a solution that will allow me to record well onto my HDD/HDDs.
I am currently looking at getting either:
4 x WD Green 2TB to go in raid 10 for $376
4 x WD Blue 1TB to go in raid 10 $268
or should i just go for a single 4TB Black on its own for $335 (but i heard the black drives are very noisy)
Like i said i am mostly looking for performance that will allow me to record HD vids without problem but the amount of storage capacity and noise output would be a large factor. (I'd obviously need enough space to store a large amount of video data.)
I think the black would give you highest performance at less noise than the others.
4 HDD's running together tends to kick out alot of irritating noise due to the way they resonate.
I have 2 caviar black and haven't found then noisy but even a loud single drive will be quieter than many driver. I think the green is a no go area as they tend to perform very poorly as anything other than storage space for films or documents.
Another option is to get a large SSD (512GB or two 256GB's in RAID from the budget) and use that. Will perform better than the HDD's, no vibrations to deal with. Just got to move the video's off the drive to a HDD when your done so you don't accidentally max it out. http://www.newegg.com/Product/Product.aspx?Item=20-148-...
I'v run a computer with maxed out HDD bays (about 6 HDD's + an SSD), if you have a decent case with some form of padding on the mounting system then drive vibrations wont be an issue.
Reds are optimized for 24x7 runtime and RAID but not parking their heads as the Green drives did for power. This should not be an issue with the blacks like it was with the Greens. Blacks will be far faster the reds.
As stated above TLER is disabled on Green, Blue, and Black drives which can lead to data lost especially in a Stripped environment like RAID0 or RAID10 since the controller might drop the drive out of the RAID.
WD Red are designed for small RAIDs up to 5 drives anything above that RE drives are recommended.
That being said I would suggest either get the Black single drive, which is fast and reliable, or build a RAID out of WD Reds
While you are discussing storage can I ask how you plan to back up all those recordings or is ok to lose it all if the drive dies? I'm only asking to get you thinking realistically about what you really need.
by the way - a 2TB drive holds about 1000hrs of raw HD recordings. My wife records quite a few shows which backs up to the windows home server I built with 8tb of storage. At one point she was 3 months behind, thankfully some soaps got cancelled. LOL
Yeah she would kill me if she lost 3 months worth of shows; hence the server which cost about 500 total. (back when drives were dirt cheap)
Im not extremely worried about backups as I already have a 4tb NAS for all my backups. Also ive looked into the RED drives and they only appear to come in sata 2, would this heavily affect my read/write speed? Would it force me to use them in raid 10 for recording HD. Otherwise i may just go with a single black drive.
Theres no difference between SATAII and III on a HDD, they are nowhere close to saturating SATAII's bandwidth.
Only exception is if the data being requested is already inside the HDD's cache, but that's fairly unlikely and will have no appreciable performance loss.
If you are going to backup your data regularly to another device, you can go with the Blacks for RAID. This will be the fasted of the solutions mentioned. If you have a problem with the array you can simply reimage from your backup.
