Will i notice a difference between SATA I and III?

[Smoblikat]

I know that on paper there is a massive difference between the two, but in real life will I notice it? I have a RAID card with 4 ports but theyre all sata 1.5 and i was wondering if I would notice a difference in speed if i set up RAID 10 on it with 4 2TB drives, versus them all running in SATA II or III mode.

No.

General HDD's such as a WD Caviar Blue max out their sequential read and write around 130MB/sec. SATA 1.5Gbps (SATA I) has a max transfer rate of 150MB/sec.

If you're using WD Blacks, or Raptors then the 1.5Gbps limit may cut the top off but other than that you will be fine.

Thats what i thought, i just wanted to double check. Thanks.

Well SATA 2 SSDs were 275 to 285mbps . SATA 3 SSDs are 550mbps ,

Hard drives, SATA1 is 100mbps SATA 2 is 275mbps and SATA 3 550mbps

Big big difference... Go SATA 3 and grab a nice SSD ,,,,,,, and you already have your hard drive which youll put stuff in like backup or installers etc....

That literally makes no sense. I have dual velociraptors so my OS drive is plenty fast, i want to amke an array of 4 2TB drives, not a small SSD that wears out over time.

Those Velociraptors and 2TB HDDs will "wear out" long before the SSDs will.

I agree. It really would be nice if this post could be deleted. If you're gonna geek out, it's either SATA Rev 1, SATA 1.5Gb/s, or SATA 150MB/s. There is no SATA1, SATA 2 or SATA 3. And you've got the speeds all wrong.

And most of all, you totally ignored the OP. They said the controller is a SATA Rev 1 controller. So "go with SATA 3" is not indicated.

SSDs should not even have been brought into this thread.

The OP wants to make an array of 4 x 2TB HDDs. It's clear from that he wants to make a large storage array. a) an SSD would be far too small for this and b) it's likely this array will take quite a hammering, so there is a fair chance it would out-live an SSD.

This array would go into a NAS that gets written to and read from daily.

Neither of us has enough information to make an accurate judgement call on which will outlast which but if it is indeed a storage array then SSDs are not the way to go.
