Raid 0 and hdd format

[Matas]

For now I have 1x Samsung HD160JJ (Sata2/8Mb/NCQ) and I'm going to buy the second HD160JJ and put them into Raid 0.
The question is: before putting them into Raid 0, should I format my Samsung HD160JJ to have it clean?

No need.

Once in raid format the pair, I recommend against using the Quick Format option.

Is it necessary to format after putting them in Raid?

In most instances, the RAID array creation process will "destroy" all the previous data on the HDD. If your RAID creating process does this, you will have to treat the array like a new HDD, i.e. format it.
