I'm super confussed with sata, Do all harddrives with with sata if you have the cables and your motherboard supports it?

I just got a new WD 7200rom 8mb cache 120gb harddrive to compete with everyone else who lives here and i'm super confuseed :confused:
 
Do all hardrive's work with sata as long as your motherboard is compatible and you have a sata cable?

Basicaly i got a new WD 120GB harddrive and dont know if i can use a sata conection or not. I know my mobo supports it, but if it will work with the ahrddrive is what i dont know.
 
Doesn't matter, it's only as fast as the harddrive sustained speed which isn't near the max transfer speed of ATA133 let alone SATA.
 
It's sort of like the point of PCIe, most games don't use the full AGP8x bandwidth let alone all that PCIe offers.
At this point it's basically just a smaller cable.
 
but that's MOST games, would this be a MOST of the time deal with a HDD?

Theoretically in my case if I were to use my harddrive, with the adapter to SATA, and theoretically If my harddrive was able to surpass the data transfer of a IDEE cable, would it even be able to use the spee d of the sata? or woud the past that its IDEE and has to use the adapter still slow it down to the IDEE speed anyways?


Also you say at this point? Arn'tharddrive's basically at there maximun potientail :? beucase it's mechanicaly and can only move so fast.

I believe that burst speeds on high quality hard drives can sometimes exceed ATA133, but I seriously doubt you'd notice the difference since average speeds are much lower, and your drive wouldn't fall into this catagory anyway.

No, you'd still be stuck at ATA133, and actually take a performance hit as the adapter has to translate the data

Disc drive data rates have not exceeded ATA100 limits yet, so why should I switch to SATA?
The maximum internal data rate on an IDE disc drive today is around 72 Mbytes/sec. The ATA/100 data transfer rate has not been reached, but one of the reasons IDE performance is where it is today is the expandable data path PATA has allowed. That data path in PATA has reached its limit. SATA allows disc drives to continue to offer performance and reliability at cost parity to PATA. In addition, SATA interface requires less voltage, meaning better power consumption and management in both desktop and mobile applications. The thinner cable allows for flexible designs and improved airflow in smaller form factors.

Will I see a performance difference in SATA drives?
You may see a 1 to 5 percent performance increase from a PATA drive to a Serial drive but, the main performance benefit is in the long run--because of SATA, the hard drive throughput will not bottleneck system performance. In the meantime, system integrators and OEMs will enjoy a big reduction in assembly time and reductions in handling damage due to connector and pin issues.

I can get 216Mbps with my raid, so we're far from SATA2 standards, or even ATA133 as others mentioned. Oh yeah, I removed that from my sig... I've got 2x 36.7G Raptor 10,000RPM drives.

No, it's all the time.Keep in mind that 216Mbps is across 2 lines so it's really ~108Mbps per drive

True, but I read somewhere that WD Raptor drives can have peak transfer speeds of up to 140MB/s, perhaps it was just a bad test though. In any case, you wouldn't notice the difference as this would probably last for less than 1 second!
