Just ordered one of these babies and was wondering what results people are getting on HD Tune.
Was also thinking about putting the 640gb and one of my 500gb in Raid 0 .Would that work.?
I know that I will only have access to 1000gb than
But oone of my 500gb has an average read time of 98mb/s which is as good as a 640gb and wanted to take avantage of it by putting it in raid 0 with the 640gb

I do believe since you are putting the new Black drive with an older drive in RAID0, the write speed of the black will be limited by the old drives write speeds. The black is a fast drive, and you will see a performance increase, but not as much as if you had two black drives (unless I missed that the 500gb is a black drive too).

EDIT: Nevermind. I see they are all blacks. I have heard that the 640 do have faster speeds than the 500, so you may get a little limiting, but not much.

Just got my 640gb Black and ran a test using HD Tune.Do these results seem normal,bad, or good.

Honestly, those results are average for a single drive.

On my sig rig (with an Opteron 165), I used to have 2x 1TB Seagate ES.2 drives in a RAID-0. I was getting roughly 250MB/s average with them short-stroked. So when you go RAID-0 you should see a pretty decent performance boost

One questions for you.I want to put the 640gb black and one of my 500gb black in Raid O.Is that possible .Here is the hd tune result of the 500gb black.See below.Its at 98mb/s average.
So therefore the 640 & 500 would be (500 x 2) correct And the average m/bs would be (96 x 2) =192MB/S.Is that right.
Also thinking about short stroking the two drives to about 250Gb than as I dont need the rest of the space

I want to put the 640gb with the fast 500gb in Raid O and than short stroke them to 250gb or so.

raiding them together u'll get 1tb of storage, and ur 640 will be as fast as ur 500, and u wont get double the speed but close to it more like 90% of the theoratical speed.

and remember u shortstroking doesnt make the drive faster it DOES lower access times but all it does is alow the drive to keep a constant speed instead of dropign down at the end.

and lastly if u shortstrok ur 1tb to 250gb ull still have another partition for 750gb which u can use for storage

Not if you want to keep the benefits of the short stroking you won't.

If you use the rest of the disk, you will force the read heads away from your OS partition every time you access your storage partition. This results in LONG seeks, and kills off all the performance benefits that short-stroking brings. The only thing I would consider using the remaining space for would be a RAID1 array containing images of my OS partition as backup (ie files that never normally need to be used).

If you want fast, don't use the extra space. Buy a 1TB Green for storage.

But i can put the 640gb and 500gb in raid 0 right.My 500gb averages 98mb/d whilst the 640 averages 96mb/s average read .So it would be (96 x 2).When i short stroke I wont use the rest of the space It will be left unpartioned.I want to get the best possible performance and use only 250gb of the 1tb.What sort of access times can i get if i short stroke to about 250gb?

Wrong. He will have 1tb of storage.

Huh?
Raid 0 is the version where you write 50% of the data on each HDD.
Therefor being limited by the lesser drive aka 500 gb?

Please enlighten me.

about the HDtune.
The raid0 is slightly faster than my single drive....and I don't think that is something awesome :<

Yup, that's how it works. Why are you confused by my post?
