SATA vs SATA II Hard Drives

[Oorja]

Can anyone tell me what the difference between SATA and SATA II is? If there is a motherboard which has SATA II, should it support SATA hard drives? If not, then is there any workaround? Do you think that the SATA II hard disk would work has a SATA?

The difference lies in the speed of data transmission. With SATA it is 150 Gbit / s and at 300 Gb / s with SATA2.

You can also add a SATA drive to a SATA2 port hang, because it is backward compatible.

It thus means that there is absolutely no difference between SATA I and SATA II standard, except the theoretically possible speed. The point of this is that the current drive by no means a 150Mb / s of data can continue. If you are looking for a SATA drive, look for data that count, such as whether the drive supports NCQ, or a power save mode, etc. A disk class SATA I or SATA II is not important.

Technically, there is indeed no such thing as SATA2. It is officially still just SATA; there are only a few revisions that we have been popularly called SATA2 and SATA3. Glad you called NCQ - that's just one of the new tricks that the second revision of SATA introduced (so SATA2).

The most striking difference would be the speed, about whether you can connect a SATA II motherboard that supports a single SATA, if you can but would work as SATA, if not so would have no gain in speed.

The SATA II and SATA are configured so that they do work on any SATA controller if you had SATA II, is set according to the manufacturer gives as some are with jumpers or some software to achieve that SATA II. And soon came SATA III come to 600MB / s.

I would add that in addition to the theoretical speed difference between SATA 1.0 and SATA 2.0, is the technology support NCQ (Native Command Queuing). NCQ is supported only since SATA 2.0 or SATA II. For this to work both hard disk controller must be SATA 2.0. Now, there is no problem if your disk is SATA 2.0 and your motherboard only supports SATA 1.0, NCQ technology simply is not activated but as you uses the disk on your system. The benefits of NCQ is noted mostly takes place in environments where large numbers of disk requests randomly and simultaneously.

The speed at which the specification refers is not the average speed that will take your HD, if not the maximum speed that could theoretically reach. And usually not even in burst HDs reach this maximum. Burst is called to read faster than you have a HD and this happens when reading directly from its internal cache, not the disc.

The first SATA hard drive with a serial interface were not native, but included a bridge between parallel and serial ATA and now SATA hard drives support natively. After the initial phase of the ATC 1.0, now in the stage 1 of the second version of SATA or SATA II Phase 1. The SATA 1.0, in fact, does not include certain features needed for server configurations and network storage and high-performance workstations. A superset of the SATA 1.0 specification and is introduced in two phases, of which the first of some interest for those who buy a new computer.

SATA II disk has to be "configured" to work as such. It seems like there are not many SATA II penetration technology (Many still work with PATA), these are factory configured as SATA (they do work on any card with SATA ports) and you have to enable SATA II as if it has a card with this support ... The configuration, as I know, it is depending on the manufacturer, some by jumper (like PATA) and others through a utility which you can download from the same manufacturer's website.

In the IDE compatibility mode, two SATA channels are grouped logically (e.g. SATA channel 0 +2, 1 +3, 4 +5) and the connected drives can be addressed simultaneously. As with the connection of drives on an IDE cable, they must take turns at the same time use, which halves the available bandwidth. Only when the drives are not both connected to the same logical network (i.e. the one drive on channel 0 and the other on channel 1) is either the full bandwidth even at the same time use available.

If you can you will work in SATA1 but you have two options, one is to put it on and walk out alone and another is to have a jumper to move it to SATA1, just plug it well and you see that wave.
