Can a PCI SATA controller-card support 3Gb/s data transfer rate?

[Guest]

(My only PCIe-slot is used for graphics, so Can a PCI-slot SATA controller-card support 3Gb/s data transfer-rate?; if so, how many SATA-ports per PCI-slot @ that speed, max? Or, if 1.5Gb/s is the highest throughput a PCI-slot can handle, again, what's the max # of SATA-ports one can handle?
In any case, any recommendations for specific cards? (System-specs follow)

thank you, very much, for any help,

Old but small. May give you some idea as to what card to buy.
Comes down to the chipset on the card it`s self also.

On thought, i would think the pci slot would be the problem, if you wanted 3Gb/s transfer.
Does your board not have a 4 lane Mini Pci-e also, as you can buy Sata II cards to work in that slot you know.

My main question is really basic: simply, are PCI-slots engineered to be able to handle a 3Gb/s data transfer-rate; or, put another way, what's the max (realistic) throughput a PCI-slot can be expected to handle.

thanks for your reply, Shaun O;
As to the ad-summaries for PCI-slot SATA controller-cards themselves, so far, one states, 'capable of supporting UP TO 3Gb/s' (thus not being clear that it actually does run at that speed), & the rest, if speed is mentioned at all, state that they run at 1.5Gb/s.
Nope, no mini-PCIe-slot, only: 1 PCI Express x16 (added EVGA graphics) & 3 PCI, one of which has a TV-tuner card, so 2 PCI-slots available (the modem-card in 1 of the 2 isn't used).

any help very much appreciated,

No, a the PCI bus can manage roughly 1Gbps and that's shared between everything on that bus (so your TV tuner and modem will use some of that bandwidth).
So really it will struggle to cope with even one SATA-I device.

Your motherboard has 4 SATA-I ports, so I'd stick with them or replace the motherboard.

Its 3gb not 3 GB. It supports up to 150 MB/s. PCI sata card can't support more than 1.5gb/s (that's 150MB read max).

Its 3gb not 3 GB, we're talking gigabits not Gigabytes. The PCI SATA card won't support modes above SATA 150, that is your PCI sata card can't support more than 1.5gb/s (that's 150MB/s read max). It'll always limit your computer that way.
