Windows Forum / Windows 98 / Disks / File System / November 2004SATA and IDE
Any way a SATA disk can be connected to an IDE header please? You can use a Promise Technology PCI adapter, such as the SATA II 150 TX2 plus which gives you 2 SATA ports and two parallel 133 ports, as well as supplying 48-bit LBA addressing, if your BIOS doesn't have it, or other such cards. Price is about $60. You probably won't see all that much of a bandwidth improvement over parallel 133, though, since SATA I isn't a huge step in speed over UDMA133, i.e, 150MBps isn't much more than 133MBps. http://www.promise.com/ There are connectors to connect a parallel HD to a serial port, but I don't know of anything the other way round. Hope this is of some use, Joe > Any way a SATA disk can be connected to an IDE header please?

Google it, man! Though short on explanation here's the math: http://english.aopen.com.tw/tech/techinside/ata133.htm  SignatureRichard G.

I expect you're right about the 150; if it's ver. 2.2, it would offer 66MHz operation, but not on the secondary, or card, bus. My chipset is presumably 2.2 and has SATA onboard, but that's clearly the primary PCI bus. If it happens to be PC-X 1.0, which dates from late 1999, but probably not on any machines seen before 2001, then it could handle the 150MBs card since it shares bus width between 32- and 64-bit devices. My impression is that this might be more detail than ATK wanted, though. Hope this satisfactorily amends my previous remarks.

Many thanks for interest shown - I suspect cost is not worth it. > 33X4B/cycle~133MBs, as always, an upper limit figure. > I expect you're right about the 150; if it's ver. 2.2, it would [quoted text clipped - 25 lines] >>> Joe >>>> Any way a SATA disk can be connected to an IDE header please? |
