Is sata-300 the same as sata-II

Hi there recently i've been thinking of upgrading my Acer 6935G's Hard Drive. At the minute from what I have checked I have a Seagate Momentus 5400rpm 250GB 2.5" HDD. Online I have found a 2.5" Seagate Momentus 500GB 7200.4rpm HDD Which i am going to buy, one thing that puts me off is that it says it's "Sata-300" which I have never come across before. Will this hdd be compatible to replace my current drive?

Cheers,
Lone

BTW here are the specs and link to the HDD Specs:

Laptop: Acer Aspire 6935G

  1. SATA 3.0 GBps is the SATA II standard. SATA 6.0 GBps is SATA III. http://en.wikipedia.org/wiki/Serial_ATA#SATA_revision_3.0_.28SATA_6_Gbit.2Fs.29

    SATA-300 is not a recognized standard and is sales-speak of some vendor.
  2. Ok thank for clearing this up, so i'm free to just swap out the old one?
  3. "SATA-300" is a poor slang, VERY likely meaning SATA II. The proper term is SATA 3 Gb/s. A lot of people convert Gb (Gigabits) to GB (Gigabytes) by simply dividing by 10 - a reasonable approximation. 3 Gb = 3,000 Mb = 300 MB. and that's where the "300" comes from.

    There is no such thing as SATA II, or SATA 1 or SATA 3.

    Those are Sales talk.

    There is only SATA, and then you got the quality(speeds) Where you got 150, 300 and 600.
    where;

    SATA 150 = 1,5 Gb/s
    SATA 300 = 3,0 Gb/s
    SATA 600 = 6,0 Gb/s

    But the therms are so often missused it has allmost become the norm.

    Check out this video from Linus Tech Tips that tells the whole story.
