A standard SATA cable, per specification, can run up to 1m (3.3ft) of length without signal losses.
An eSATA cable can, per specification, run up to 2m (6.6ft) of length without signal losses.
18 inches was the technology's specified maximum length. 45cm for metric. There are a few 65cm cables out there that work without errors (25.5 inch cables), but they are more expensive and are typically guilded and braided in order to address interference. 90cm (35.5 inch) cables were also made, but I've found these do not work properly outside of specific cases.
18 inches was a good limit, and ensures error-free operation.
PATA cables have a maximum length barrier of 18-inches (46 cm). This information is readily available through Google.

The current maximum length for a serial cable is around 50 meters. Different cables have length limits with the maximum varying.
No disadvantage one disadvantage is that you can't use it in an IDE only box. --- Sata drives can be used in an IDE only computer using a cheap sata to IDE reversible interface. IDE<>SATA SATA<>IDE Another disadvantage is that serial devices driven at high speed can be subject to interferrance if the cable length is too long. This is not unique to SATA (IDE suffers from this too) But until an alternative system such as Fibre optics cable is introduced it will limit lead length. ---
Check the motherboard. You can connect two drives to a single parallel cable. Most traditional motherboards have two IDE sockets and you can run a maximum of four drives. (one cable per socket, two drives per cable) but you need to configure the drives with jumpers as "primary" and "slave". Many of the newer motherboards have a "SATA" (Serial ATA) socket or some combination of SATA and IDE but you'd have to use a SATA drive with a SATA cable to use the SATA socket.

The maximum length of a cat 5 e cable with out a repeater is 100meters
You cant connect two devices to the same sata cable.
40 Pins and 80 wires. Maximum recommended length is 18" but can purchase 24" cables.
maximum is 100 meters or 328 ft
SATA, or serial advanced technology attachment, connects the motherboard to hard drives and optical drives. This cable is inserted into the SATA slot on the motherboard.
