One of the problems associated with the transmission of data at high speed over electrical connections is described as noise (Common mode and differential), which is due to electrical coupling between data circuits and other circuits. Left-angled (also called 270-degree) connectors lead the cable across the drive towards its top. Right-angled (also called 90-degree) connectors lead the cable immediately away from the drive, on the circuit-board side. Angled connectors allow lower-profile connections. SATA connectors may be straight, right-angled, or left angled. Although they are more susceptible to accidental unplugging and breakage than PATA, users can purchase cables that have a locking feature, whereby a small (usually metal) spring holds the plug in the socket. Thus, SATA connectors and cables are easier to fit in closed spaces and reduce obstructions to air flow cooling. However, cables up to 35 in are readily available. PATA ribbon cables, in comparison, connect one motherboard socket to one or two hard drives, carry either 40 or 80 wires, and are limited to 18 in length by the PATA specification. SATA cables can have lengths up to (3.3 ft.), and connect one motherboard socket to one hard drive. The SATA standard defines a data cable with seven conductors (three grounds and four active data lines in two pairs) and 8 mm wide wafer connectors on each end. Standard SATA connector, data segment Pin # SATA is full duplex, differential, with a transmit pair and receive pair. The SATA cable results in a higher signaling rate, which corresponds to faster throughput of data. Data is moved one bit at a time between a SATA drive and its host, using a seven-pin data cable and 15-pin power cable. As its name suggests, a Serial ATA drive transfers data in serial fashion. PATA is Half Duplex, meaning transmit and receive cannot occur at the same time. The SATA SSD transport layer differs from PATA drives, in which data bits are delivered simultaneously across a 40/80 -pin-wide ribbon cable. Technical Differences Between SATA and PATA ![]() The redundant array of independent disk (RAID) mode supports both AHCI functions and RAID data protection features. Setting a SATA controller to Advanced Host Controller Interface (AHCI) offers higher performance than IDE mode, and enables features such as Hot Swapping on SATA drives. Putting SATA in IDE mode means the hard drive is recognized as a PATA device - a situation that provides better compatibility with older hardware, but comes with the tradeoff of lower performance. Serial ATA hard drives connect to a computer’s motherboard via SATA Controller hardware that manages the flow of data. SATA cables are thinner, more flexible and smaller than the ribbon cables required for conventional PATA hard drives. SATA SSD has several advantages over the Parallel PATA hard drives developed in the 1980s. It evolved from PATA, and shortly after its introduction replaced PATA in PCs and other systems. **If there is any DOUBT though I'd buy a better power supply.Serial ATA was introduced in 2003. You'd have a major PROBLEM if it was an overclocked FX-8350 or FX-9590 or similar though. Some overclockables ones are also fine but it varies by the overclock. Most modern CPU's use between 70 and 150W (including motherboard)… any modern Intel that's not overclockable should be fine. If we assume 350W as a worst-case for sustained power draw then you've got 200W for the rest of the system. The fact that the graphics card only has a 6-pin PCIe means it's not going to draw 150W of power. I won't bother discussing how RAILS work but for this post the answer to should he be worried is: The 12V power draw ends up coming from the same source. If you know what your PSU can do and the power draw of the system then adapters are perfectly fine to use. Just shows that the power supply isn't adequate to run your setup. ![]()
