alright so i missed out on the 640 black deal.
but i saw these blue 640gb:
http://www.amazon.com/Western-Digita...9273869&sr=1-1
and i was wondering if these set up with RAID 0 would be better than one of theses.

What do you guys think?
Also any other good drives out there for about the same price range?

Significantly... Pretty much any >320GB 7200rpm drive in Raid0 is faster than any other 7200RPM drive.

Each of those 640GB's alone is slightly faster than the 1.5TB.
SO you think those are a better deal than de 1.5 tb?
2 640s will smoke any single hard drive.
do you guys know of any other good hard drives on deals?

If you wanted 1.5TB for some reason Newegg has them for $97 I believe.

Yes, and the cows are capable to fly.

I doubt that the black (not the blue like those in the link) are faster than the 1.5TB. The blue are slower.

Remember that a RAID0 improves only the transfer rate, not the access time. If you are using it for the OS, a RAID0 setup is virtually useless (in normal OS use, you access a lot of little files so, only the access time is important).
An OS on a RAID0 is a valid solution only using SSDs, because usually the SSD are slow in transfer rate.

If you need it for OS, I suggest you to go for the 1.5TB or for WD black(s).
If you need it for storage, the transfer rate of the 1,5TB is higher than every WD (a single HD, not a raid0!).

So for gaming/ everyday use of a comp there really is no need for RAID0?
Orr like what software actually uses RAID0?
Hmm 1.5tb for 100 bucks or 2x 750gb black?

A raid0 improves the transfer rate of the HD, ie when you transfer big files.
A raid0 probably improves the loading time of the games. But it's virtually useless when the OS access to a lot of very little files (4 Kb or less).

If your target it's to use it as main HD (the only hd really), 2x750 black are faster than a single 1.5TB. The access time is probably the same (and there is no improvement in the OS loading/normal work), but the transfer rate is better and you can gain performance when you load games or when you transfer big files.

You have to choose if you prefer a better performance sometime (not always), or if you prefer to save money (I think that 2x750 WD black is more expensive that a single 1.5TB).

I went with the 1.5 tb on amazon for 89.99 =]. I think it was a grat money saver as the other ones came out to be about 130 shipped. http://www.amazon.com/Seagate-Barrac...9321008&sr=1-1
I have 5 1.5TB and I'm happy with them. Here in italy is difficult to find WD black (and I hate WD, so I'm not a fair source...).
The 2x750 are faster (probably the overall transfer speed will be about 150-180% respect a single 1.5TB), but 130 is about 1.5 times the price of the 1.5TB... I can't suggest you what to do. It's all about if you think that the faster speed worth the additional 40$.

Without getting into an argument here, you could check out this article on RAID-0 for further reading.
http://www.hardwaresecrets.com/article/394/1

I personally run multiple RAID-0 arrays on my workstation, but I also happen to work with a lot of virtual machines, where the files sizes are 80GB - 200GB in size, so it makes a difference for me. Overall, you'll probably notice a real-world "snappiness" on a RAID-0 array, but not a doubling of speeds vs a single drive.

I agree. When I wrote about the transfer rate improving, it was the maximum possible speed. The real increase depends from the type of use of the HD.
I'm also using several Raid0 arrays, but mainly for data storage/transfer.
For the OS I preferred a single SAS 15K rpm disk (I don't trust SSD for now).

If the access time remains unchanged, and the read / write speed is drastically higher, then what's not to like about the RAID? I don't know exactly how fast the 1.5TB drive in question is, but I get better access time with my two 640 blues in RAID0 on the ICH10R than I do with a single 1.0Black on the same controller. Also, I think many will agree with me that there is a noticeable difference when running your OS on an array.
