Thread: SATA versus SATA 2 Hard Drives Hardware

Can someone tell me what the difference among SATA and SATA 2 is? If there is a CPU board which has SATA 2, should it support SATA hard drives? If not, then is there any workaround? Do you imagine that the SATA 2 hard disk would function has a SATA?

The dissimilar lies in the velocity of information transmission. With SATA it is 150 Gbit / s and at 300 Gb / s with SATA2. You can too include a SATA drive to a SATA2 port hang, because it is backward compatible.

It thus means that there is perfectly no difference among SATA I and SATA 2 standard, except the theoretically possible velocity. The point of this is that the recent drive through no means a 150Mb / s of information can continue. If you are excepting for a SATA drive, look for information that count, such as whether the drive supports NCQ, or a power save mode, etc. A disk class SATA 1 or SATA 2 is not significant.

Technically, there is surely no such thing as SATA II. It is officially even only SATA; there are just a some revisions that we have been popularly named SATA2 and SATA3. Glad you named NCQ – that is only one of the fresh tricks that the second revision of SATA introduced.

The most striking dissimilar would be the velocity, about whether you can attach a SATA 2 CPU board that supports a individual SATA, if you can but would function as SATA, if not so would have no increase in velocity. The SATA 2 and SATA are configured so that they do function on any SATA controller if you had SATA 2, is fix according to the producer gives as few are with jumpers or few software to get that SATA 2. And soon arrived SATA 3 come to 600MB.

The velocity at which the specification choose is not the average velocity that will assume your HD, if not the maximum velocity that could theoretically reach. And commonly not still in burst HDs reach this maximum. Burst is named to read quicker than you have a HD and this occurs when reading exactly from its inner cache, not the disc.

If you can you will function in SATA I but you have 2 alternatives, one is to insert it on and walk out alone and another is to have a jumper to impress it to SATA1, just attach it well and you see that wave.
