samsung f1 question

Raid 1 is just mirroring I think, and so the speed will not be any different, maybe a slight overhead in sending the data twice, but on todays computers it makes no noticeable difference, RAID 0 is splitting where the PC splits data over 2 drives to make it faster, it WILL be faster on read/write times, but only noticeable on huge files, also your pc may boot faster, random access speed wont be any different, if you want 'snappyness' get a 10k or 15k rpm drive
 
My new drive:


Now compared to my 2x WD 640GB in RAID 1:

Not sure why mine is faster in RAID 1 as I have seen other peoples single drivers get 1 or 2 MB faster.
 
negligible

The difference is not vast, so thats fine. RAID 1 is just writing the same data to both drives at once, creating a mirror image.

Some drives of the same model/type/capacity are sometimes just faster than others. My Samsung F1 is slightly slower than some benchies I have seen on here, and her access time is 17ms, compared to some that are 13-14.
 
some raid1 controllers allow you to read data from both disks, increasing performance. I dont know if any of the onboard controllers support this. It obviously doesnt apply to writes, since both disks are doing the same then.
 
RAID 1 uses an algorithm to distribute read requests between the disks, which improves read performance. So the slight write speed loss isn't so bad if you take that in to consideration :)
 
There's no technical reason why RAID1 shouldn't offer twice the read speed of a single disk as it could split the data to be retrieve equally and get half of it from each drive. Why don't the controllers do this?
