Hi guys,

I will be using the drives as storage only. Which one is the best setup? Are there any significant differences in terms of speed?

The drives I will be using are:
ST6000NM0024 - Seagate 6TB ($ 672.55)
ST3000DM001 - Seagate 3TB ($ 150.83)

 
Solution
if it was me, i'd take 2x3tb, since it's cheaper. and if one fails i still have the other. of course that is if i still have sata ports to spare
Hey there, erdem84.

That depends on how much storage space you need. Judging by the prices I assume you mean 2x3TB or 2x6TB, is that correct? Because if this is the case, the it's all up to your personal preference and the maximum storage capacity supported by you motherboard and/or OS.
One piece of advice though, If you plan on having such so much storage capacity available, I assume you might want to store most or all of your data there, so I'd suggest that you don't go for a RAID0 if you don't have any backup of your most important data on a separate drive (which is not connected to your system). As you probably know, with RAID 0 if the worst happens and one of the drives fails, you lose all your files.

Hope that helps.

Hey there, Boogieman_WD.

Nope I was asking about 1 x 6 TB or 2 x 3 TB. Or maybe a 3rd option can be made such as 2x4TB. I need between 6 - 8 TBs. I have a board that supports UEFI and 2 spare Sata 3 ports. I will go with Raid 0 because what I will store is movies, mp3s and such so no important data and I will back them up using DVDs or BDs. I mean will I be able to use this drive as a storage? Up to how many TBs can Win7 handle as storage not for booting? I know that I can use Raid 0 up to 8 disks though I will only use 2 disks.

By the way as I found a representative from WD. What is the best grade hdd of WD? I mean I used green ones but they were real crappy. I assume that WD Black is the top notch excluding Velociraptor. Am I right?
 
Well, if this is the case, I'd go for 2x3TB as @Cons29 has suggested. This way you'll get the extra speed of the RAID 0 configuration, compared to the regular speed you'll have with a single 6TB drive (I guess you are aware that in order to setup RAID 0 you need at least 2 physical drives). In addition, you'll always have an extra drive if the worst happens and one of them fails, which you'd be able to reformat and use as a regular secondary storage HDD.
Windows 7 won't have trouble handling the storage capacity you are describing, but your motherboard might have an issue with that. Usually in the specs for the motherboard it says "up to" and states the maximum storage capacity, which the SATA controller is capable of handling. If you can't find it, just go ahead and contact your motherboard manufacturer's customer support and ask for that info.
Just FYI, I'd double check the prices of the drives you mentioned if I were you, because that's what made me thing you were talking about 2x6TB and 2x3TB.

Well, in my country the cheapest prices of 6TB Seagate 7200rpm is $ 616.52 WD60EFRX (WD Red 6TB 5900rpm) is $ 365.48 and WD60EZRX (WD Green 6TB 5900rpm) is $ 295.27 all including VAT. I have checked the board manual (Sabertooth Z77) and googled but haven't found a maximum storage capacity it only writes that up to 6GB/s meaning it is Sata 3 xD.
 
Well I guess that you won't have any trouble with 6TB storage capacity with this motherboard, no matter if it's a RAID setup or a single drive.
If you are considering WD drives for a RAID configuration I'd suggest that you take a look at the WD Red drive (instead of the WD Green one). They are designed to be used in NAS/RAID environments and feature specific firmware, which optimizes they performance in NAS/RAID configurations. Of course, you should pick whatever suits your needs and budget best.
