SATA revisions are typically designated with a dash followed by Roman numerals , e. First-generation SATA interfaces, now known as SATA 1.
The theoretical burst throughput of SATA 1. During the initial period after SATA 1. Bridged drives have a SATA connector, may include either or both kinds of power connectors, and, in general, perform identically to their native-SATA equivalents.
Native SATA products quickly took over the bridged products with the introduction of the second generation of SATA drives.
SATA revision 2. It is backward compatible with SATA 1. Second-generation SATA interfaces run with a native transfer rate of 3.
The theoretical burst throughput of the SATA revision 2. All SATA data cables meeting the SATA spec are rated for 3.
Announced in August , SATA revision 2. Announced in February , SATA revision 2. Third-generation SATA interfaces run with a native transfer rate of 6.
The theoretical burst throughput of SATA 6. In general, the enhancements are aimed at improving quality of service for video streaming and high-priority interrupts.
In addition, the standard continues to support distances up to one meter. The newer speeds may require higher power consumption for supporting chips, though improved process technologies and power management techniques may mitigate this.
The later specification can use existing SATA cables and connectors, though it was reported in that some OEMs were expected to upgrade host connectors for the higher speeds.
Released in July , SATA revision 3. Released in August , SATA revision 3. Released in February , SATA revision 3. The new Power Disable feature similar to the SAS Power Disable feature uses Pin 3 of the SATA power connector.
Some legacy power supplies that provide 3. Released in June , SATA revision 3. Connectors and cables present the most visible differences between SATA and parallel ATA drives.
Unlike PATA, the same connectors are used on 3. Standard SATA connectors for both data and power have a conductor pitch of 1. Low insertion force is required to mate a SATA connector.
A smaller mini-SATA or mSATA connector is used by smaller devices such as 1. A special eSATA connector is specified for external devices, and an optionally implemented provision for clips to hold internal connectors firmly in place.
SATA drives may be plugged into SAS controllers and communicate on the same physical cable as native SAS disks, but SATA controllers cannot handle SAS disks.
Female SATA ports on motherboards for example are for use with SATA data cables that have locks or clips to prevent accidental unplugging.
Some SATA cables have right- or left-angled connectors to ease connection to circuit boards. SATA cables can have lengths up to 1 metre 3.
Thus, SATA connectors and cables are easier to fit in closed spaces and reduce obstructions to air cooling. 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.
SATA connectors may be straight, right-angled, or left angled. Angled connectors allow lower-profile connections. Right-angled also called degree connectors lead the cable immediately away from the drive, on the circuit-board side.
Left-angled also called degree connectors lead the cable across the drive towards its top. One of the problems associated with the transmission of data at high speed over electrical connections is described as noise , which is due to electrical coupling between data circuits and other circuits.
As a result, the data circuits can both affect other circuits and be affected by them. Designers use a number of techniques to reduce the undesirable effects of such unintentional coupling.
One such technique used in SATA links is differential signaling. This is an enhancement over PATA, which uses single-ended signaling.
The use of fully shielded, dual coax conductors, with multiple ground connections, for each differential pair  improves isolation between the channels and reduces the chances of lost data in difficult electrical environments.
SATA connector on a 3. The two different pin lengths ensure a specific mating order; the longer lengths are ground pins and make contact first.
SATA specifies a different power connector than the four-pin Molex connector used on Parallel ATA PATA devices and earlier small storage devices, going back to ST hard disk drives and even to floppy disk drives that predated the IBM PC.
It is a wafer-type connector, like the SATA data connector, but much wider fifteen pins versus seven to avoid confusion between the two.
Some early SATA drives included the four-pin Molex power connector together with the new fifteen-pin connector, but most SATA drives now have only the latter.
The new SATA power connector contains many more pins for several reasons: . There are also four-pin Molex-to-SATA power adapters that include electronics to additionally provide the 3.
Pin 1 of the slimline power connector, denoting device presence, is shorter than the others to allow hot-swapping. There is also a micro data connector, similar in appearance but slightly thinner than the standard data connector.
Standardized in , eSATA e standing for external provides a variant of SATA meant for external connectivity. It uses a more robust connector, longer shielded cables, and stricter but backward-compatible electrical standards.
The differences are:. Aimed at the consumer market, eSATA enters an external storage market served also by the USB and FireWire interfaces.
The SATA interface has certain advantages. Most external hard-disk-drive cases with FireWire or USB interfaces use either PATA or SATA drives and "bridges" to translate between the drives' interfaces and the enclosures' external ports; this bridging incurs some inefficiency.
Some low-level drive features, such as S. In those cases SATA drives do not have low-level features accessible.
Therefore, eSATA connections operate with negligible differences between them. As of mid few new computers have dedicated external SATA eSATA connectors, with USB3 dominating and USB3 Type C, often with the Thunderbolt alternate mode, starting to replace the earlier USB connectors.
Still sometimes present are single ports supporting both USB3 and eSATA. Desktop computers without a built-in eSATA interface can install an eSATA host bus adapter HBA ; if the motherboard supports SATA, an externally available eSATA connector can be added.
Notebook computers with the now rare Cardbus  or ExpressCard  could add an eSATA HBA. With passive adapters, the maximum cable length is reduced to 1 metre 3.
Both USB and eSATA devices can be used with an eSATAp port, when plugged in with a USB or eSATA cable, respectively. An eSATA device cannot be powered via an eSATAp cable, but a special cable can make both SATA or eSATA and power connectors available from an eSATAp port.
An eSATAp connector can be built into a computer with internal SATA and USB, by fitting a bracket with connections for internal SATA, USB, and power connectors and an externally accessible eSATAp port.
Though eSATAp connectors have been built into several devices, manufacturers do not refer to an official standard. Mini-SATA abbreviated as mSATA , which is distinct from the micro connector,  was announced by the Serial ATA International Organization on September 21, Slim 2.
By combining the data signals and power lines into a slim connector that effectively enables direct connection to the device's printed circuit board PCB without additional space-consuming connectors, SFF allows further internal layout compaction for portable devices such as ultrabooks.
Pins 1 to 10 are on the connector's bottom side, while pins 11 to 20 are on the top side. SATA Express , initially standardized in the SATA 3.
The host connector is backward compatible with the standard 3. It was concluded that doubling the native SATA speed would take too much time, too many changes would be required to the SATA standard, and would result in a much greater power consumption when compared to the existing PCI Express bus.
In addition to supporting legacy Advanced Host Controller Interface AHCI , SATA Express also makes it possible for NVM Express NVMe to be used as the logical device interface for connected PCI Express storage devices.
It replaces the mSATA standard, which uses the PCI Express Mini Card physical layout. Having a smaller and more flexible physical specification, together with more advanced features, the M.
The M. While mSATA took advantage of the existing PCI Express Mini Card form factor and connector, M. Supported host controller interfaces and internally provided ports are a superset to those defined by the SATA Express interface.
Essentially, the M. Like M. In order to provide maximum backward compatibility the U. The physical layer defines SATA's electrical and physical characteristics such as cable dimensions and parasitics, driver voltage level and receiver operating range , as well as the physical coding subsystem bit-level encoding, device detection on the wire, and link initialization.
Physical transmission uses differential signaling. The SATA PHY contains a transmit pair and receive pair. When the SATA-link is not in use example: no device attached , the transmitter allows the transmit pins to float to their common-mode voltage level.
You can run up to four drives, but the system has power connectors and space for only two - for the others you'll need power converter cables and to find a place to mount them either in the floppy bay or using a 5.
I have finally bought another sata drive and need to decide if it will be internal or external. I would prefer internal if at all possible.
I understand your comments on the power connections. I currently have 2 sata drives, 2 optical drives and a floppy drive and ATI X XT PE video card which required it's own power connector over and above power from the bus.
Even if I was able to get a connector that allowed me to add the drive internally I am a little concerned my power supply may not be up to powering all the devices.
Hope this helps. Post the issue in the appropriate Board, where they will be answered. Thanks for the info and links.
The problem is that I don't know if I have a 4-pin molex power connector left free to convert for use on another sata drive.
I rather thought I did not as I have all the drive bays full with the hardware I mentioned above. Unfortunately the PC is located in a spot that it is difficult to take out for opening up, but it may just be what I will have to do in order to find out if I have any additional connectors available.
Too bad they don't have the same cables as a Y-connector so it could still feed the original drive as well as a new sata drive. You are right.

If this helps it's the motherboard from a Dell XPS MT. And also will SATA 1 or 2 bottleneck RPM drives?
I know 3 won't because that can't even bottle neck SSDs at the moment. Eximo Titan Ambassador. May 27, 17, 87, 4, That motherboard is likely to have SATA II with the intel chipset.
It may have a third party controller that offers SATA III. SATA I 1. A new standard will be available called SATA Express in the near future.
SATA III will be the consumer standard for the next several years. Jul 2, 12, 38 64, 2, Almost positive it's SATA 2. Feb 11, 0 11, Dereck47 Splendid.
