What's the Maximum Read/Write of SATA II (3Gb/s)?

[Yamcha]

Hi Guys,

I'm just curious as to whats the maximum read/write capability of SATAII (3GB/s)? I'm asking because I bought a SATA6GB/s SSD and would like to know what speeds I should expect with SATAII?

3gbs = 375MBs

so 375MB/s theoretical maximum, maybe reduce 15% for overhead, around 300MB/s

Maximum speed is 3Gb/s /(10B/b)=300MB/s. Remember, the encoding scheme that SATA uses has 10bit bytes (essentially).

Real life tests with SSDs seems to get around 285MB/s for the SATA 2. I guess SATA 3 would be useful for a RAID with cards using the Port Multiplier function although even that would be kinda complicated and overpriced given the thing you can get that Supermicro card that doubles as SAS/SATA RAID adapter for less than 100$, I mean the AOC-SASLP-MV.
