Hi,
I have a 1TB Samsung F1, I want to increase disk performance. Would I gain much performance by adding 2 additional Samsung F1s and have them running in RAID 5?

Thanks for any help in advance.
 
Thanks for your help, will it be quicker then RAID 1? I know the RAID 0 is quick, but don't want risk one of the drives failing.
 
Thanks for input everyone, much appreciated, prolly can't justify spending the money on the 4th drive, I will check out RAID 10.
 
Were you planning on using onboard RAID? If you have a decent controller, RAID 5 would be fine.
I'm running 5 Sammy F1 1TB drives in RAID5, on an enterprise class controller and am very happy with the performance.
 
get two smaller drives for raid 0 if you want all out performance, and a the best price/gb large capacity drive as a 3rd for backup. hell, get as many drives as you want and raid 0 them, then a huuge one on its own for backup.

So far in about 12 years or raid 0 using I'm fairly sure I've yet to lose data from raid array dying, over, maybe 7-8 different raid setups, most used for ages before being retired.

Maybe theres something to the fact that though spinning all the time like any other drive, read and writes might be faster but are spread out across the drives. Its more likely the mechanical parts fail than anything else and with each drive doing half the workload it probably helps with reliability tbh.
 
If you have a proper (hardware) RAID card, RAID 5 won't be any slower writing and may be very slightly faster when reading (RAID 0 performance improvement is over-rated), and will clearly be more reliable. With on board RAID, the performance will be ever so slightly muted.

But to be honest, the F1 is arguably the fastest standard SATA drive available. It even competes well with the Raptors...

You can possibly squeeze extra performance out by careful disk management. I have OS and apps on different drives and the key volumes are on the outer edges of the disks (ie the first volume on each disk) where the transfer rate is the fastest (more sectors per track than inner tracks).

Is this an intellectual exercise or do you have a perceived speed problem? You have an o/c Q6600 and fast RAM, so I suspect you PC can already hold it's own.
 
Thanks again for everyone's input, I'm learning a great deal with all this information, therefore much appreciated.

I think my system is quick, but I want work on the HDD department to get bit more performance, but I don't benchmark anymore, So it would have to feel quick in general use for me to notice the difference,

I will be using onboard RAID as I don't want to spend money when I got one onboard, saying that I got given 2 x 36GB 2.5" SAS SCSI drives the other day, so I have been looking on auction site to see if I could get a cheap SAS controller.

HD Tune is reporting the wrong volume size for some reason, should be ~3.8TB
