Great card but only for up to 2tb capacity drives,
Verified Purchase(What is this?)
This review is from: Syba 4 Port SATA II PCI-Express x4 Controller Card Optional 2 Port eSATA (Personal Computers)
Fitted this to an aging AM3 motherboard / setup that i've recycled into a media server.
Added 4 ports to the existing 5 ports to make a 9 drive server.
Installed the card, recognised in bios straight away, installed drivers in Windows 7 64 via supplied CD (can also be downloaded from Windows Update).
All works fine, speeds are excellent too.
I fitted this in a spare PCI-E x16 slot and it works absolutely fine :)
Update (20-MAR-2013): The card doesn't appear to support the full capacity of 3tb drives, even when set to GPD, Windows wouldn't reveal any more than 2tb with this card.
Plugged the drives into the motherboard and Windows now registers all 2.72tb.
I couldn't find any firmware update on the Symba website so i guess this card is good but only up to 2tb drives.

Are you sure this problem is not due to a metric to conventional memory conversion? Traditionally, memory is converted between units by a multiple of 1024 and this is the way Windows and most programs read it.
1024 bytes make a Kilobyte
1024 Kilobytes make a Megabyte
1024 Megabytes make a Gigabyte
1024 Gigabytes make a Terabyte
However recently hard drive manufacturers have been beginning to use a multiple of 1000 for reasons of simplicity and to make their drives seem bigger.
In this case,
1000 bytes make a Kilobyte
1000 Kilobytes make a Megabyte
etc... and you end up with a Terabyte that is significantly smaller.
3 metric Terabytes = 3,000,000,000,000 Bytes. I divide this by 1024 four times to get to conventional Terabytes. 3,000,000,000,000/1024/1024/1024/1024 = 2.72848..... Try this yourself on a calculator. Its not the SATA card that's at fault but the hard drive manufacturer. You will probably find something in tiny print at the bottom of the packaging for the drive saying "3TB = 3,000,000,000,000B" and this is what makes this dodgy marketing technique legal.
