sata conversion rate

[kleentribble78]

Am a bit confuddled right now....how can Sata II which transfers data at 3gigabit per second be equal to 300MB

It does not compute

it should be either 375MB/s (based on 1000) or 384MB/s (based on 1024). I'd have thought. I've looked at several websites and worked out gigabits to megabits then megabits to megabytes.

can anyone help

not quiet getting your question but a gb/s is a gigabyte per second....I think LOL

If you think SATA goes at 3GB a second...

Wow.

If only lol.

(humble pie baked and ready for eating just in case)

One champion for the cause is microsoft not seemingly recognizing the manufacturers purchasing of the byte convention.

They still record data movement as it should be said. None of this gigi killi megi blah blah bs

i think i've worked it out

RAID II transmits data at 3gb/s which is advertised also as 300MB/s

normally to convert gb/s to MB/s would be as follows:

3gb x 1000mb/s = 3000mb/s(megabits)

then

3000/8=375MB/s (HERE is the problem)

375MB/s is not the 300MB/s as stated on the SATA II specs

however theoretically it is 375MB/s but then when you take into consideration "overheads"

the 375MB/s becomes 300MB/s as 20% is used up in overheads and is not actual hard data.

i.e. 80% of 375MB/s is 300MB/s

sorry to waste time, problem solved.sorry ppl.

U gotta remember also, that although the connections *technically* are rated that high, similarly to the way ethernet, firewire and usb are rated, u will never experience those speeds in practice due to the protocols that are used over the connections.

I believe SATA1 is yet to be saturated.
