Hard Drive Question

[Funyuns101]

I'm sure someone knows this stuff...

So now there is this Sata II thing... what's the diff between that and SATA I ?

also, what is 7200.8 or .9?

just curious as i was browsing thru newegg~

7200.8=NCQ 1.5GB drives SATA1
7200.9=NCQ 3.0GB drives SATA2

both of these are just model numbers that are used only by Seagate.

sata II doesn't really matter that much because even if you have a sata II mobo and a sata II hard drive, you cannot push anywhere near the theoretical 300mb/s.

Check it out holmes.

7200.8 and .9 denotes different generations of Seagate's hard drives. The higher the number, the newer the generation (and usually, faster performance). The difference between SATA and SATA II is really with its featureset. Its rather confusing at this point, as some SATA II drives operate at the original 150MB\s rate, but offer NCQ (Native Commande Queing), Hot Plug Aware, etc. Others can say that they are SATA 3G which can mean that they are 300MB\s, but not offer support for SATA II features.

Also remember that the rate at which the drives operate (150MB\s, 300MB\s) does NOT mean that the drives will always run at this speed (some people get confused about this, so I thought I should mention it). It is simply a ceiling of how fast the drives can THEORETICALLY operate.

Hi, Just a reminder. SATA drives are Serial Devices and IDE drives are Parallel. Serial drvices are rated in BITS PER SECOND and Parallel devices are rated in BYTES PER SECOND. Divide the SATA specs by 8 to get BYTES PER SECOND. Jim
