Question : SAS HBA - PCIe 1x?

Does anyone know of a SAS HBA that is either PCIe 1x or PCI?

All the PCIe ones I can find are 4x or 8x.  

I need it for an LTO4 tape drive.

Thanks.

BTW, I think the x1 only supports 250mb/s, I don't think there are any x1 SAS cards out there as x4 and x8 are standard to get at least 300mb/s throughput
