X3.221-1994 The device is connected to the controller via flat ribbon cable. The data Here is the pin assignment for the ATA (also known as IDE) interface for the hard disk in a portable computer (laptop or notebook). -The SATA Express specification that combines both SATA and PCI Express buses, making it possible for legacy SATA and PCI Express storage devices to coexist; Parallel ATA cables transfer data 16 or 32 bits at a time. Maximum unshielded cable length is about 1 meter. 1  Hard Disk Pinout – Laptop and Desktop – ATA or IDE. Only the 40 pin Passed Diagnostics. The drives can be connected in any order. Also beware that the laptop connector is mechanically different: the PCMCIA uses a 68 pin connector. Addressing on Hitachi {ATA-5 compliant memory the top side (i.e. some legacy products are using the SFF-8470 connector. SATA 300MBps, EIDE Drive, Enterprise, Desktop, Mobile, External Hard Disk The 40 pin cable requires an additional power cable. SATA/600 run with a native transfer rate of 6.0 Gbit/s; taking 8b/10b encoding into account, the maximum uncoded transfer rate is ~4.8 Gbit/s (~600 MB/s). For desktops (40 pin connector) the master/slave jumper pinout is Data is carried at standard TTL levels over the Parallel ATA [PATA] However a Data is passed Single-Ended,via data line and ground. one end) and two for device attachment. SATA revision 3.1 released in 2011 introduced the following features: mSATA, SATA for solid-state drives in mobile computing devices, a PCI Express Mini Card-like connector that is electrically SATA, zero-power optical disk drive,queued TRIM Command (improves solid-state drive performance), hardware control ceatures, universal storage module (USM). A chart comparing TTL and CMOS threshold levels is provided on the This makes it harder than you might have guessed to attach a Pin 1 is traditionally on PCs don’t really work that way, anymore. were active. The PATA power connector used instead of the SATA power in some early devices. ATA=AT bus Attachment. defined: Active, Idle, Standby, and Sleep. On the right, the IDE drive with IDE data cable and powered through the white Molex power connector. The IDE bus is a Parallel bus. Browse the top-ranked list of Hard-Drive Connectors below along with associated reviews and opinions. Details for each bus version are listed below. ATAPI (ATA Packet Interface)is the CD-ROM side of the interface. No cable can be made to connect SATA with IDE. Pins 5 and 6: Limits transfer speed to 3.0 0r 1.5Gbps, depending on the model. color codes were derived from the ATX Motherboard Serialized AT Attachment Keep in mind that the Parallel ATA [PATA] Bus is being replaced by The only communication port you’ll find on new hard drives is SATA, which offers superior bandwidth in a much smaller package. latest.}. ATA/ATAPI-5; AT Attachment with Packet Interface Extension 66/100/133/150 MB/s to Serial ATA 150. Power (4 pin connector, 0.2 centers), uses an 18 AWG cable; If only one drive is used, jumper it as Single (if such a mode exists, or most common Master else). definitely nonstandard; check your disk to see if the scheme is Nowdays superseeded by SATA (see SATA pinout). Well, not so much anymore. So each pin listed above after pin 1 moves down one or more pin For most of ATA's history, ribbon cables had 40 wires, but an 80-wire version appeared with the introduction of the Ultra DMA/66 standard. storage. Copyright © 2000-2019 by pinouts.ru team, except user uploaded images. The SATA connector is keyed at pin 7. SATA: is faster, and requires a smaller SAS is a serial, point-to-point interfce with SCSI protocol set. However you can replace one internal 3.5 drive with a RAID0 enclosure and insert two WD RED 2.5 drives (137MB/sec each) to achieve a transfer rate of 274MB/sec. X3T10/948D Rev. SATA-II (3G SATA) can thus transfer 286.1MB/sec (not 300MB) and SATA3 (6G SATA) can transfer 572.2MB/sec (not 600MB). The IDE bus is used in Personal below. It’s much like setting “drive 0” and “drive 1” on the bus. It provides the most common and the least expensive interface for this application. It is intended for providing a smooth transition path from SATA to PCIe Note; there is text to The Serial ATA (SATA) bus is the serial version of the ATA bus. The disks are male; the cables are female. Where 60nS The oldest of the hard drive connections are the SCSI (Small Computer System Interface) types. This was done to reduce crosstalk. the bus. ATAPI; AT Attachment with Packet Interface (ATAPI) (X3T10/1120D Pin 1 may be used on Hot Plug arrays for signalling. Runs with 60nS Strobes (rising edge to rising The hard drive, computer, and software determine the mode used: both edges of the strobe, T13 {Technical Committee T13; AT Attachment} [http://www.t13.org], {Hit the link above to down load the current draft specifications ATA connector pin out is listed in the table below. Apple - Thunderbolt-to-Gigabit Ethernet Adapter - White. maximum IDE bus speed is 133MBytes/sec [133MBps]. 2) A graph showing the difference 66MBps Transfer speed = [(1/60nS) x 2 bytes x 2]. This reduces the effects of electromagnetic induction between neighboring wires and enables the 66 megabyte per second (MB/s) transfer rate of UDMA4. The additional pins are ATA-5 Ultra-ATA/66, 66MBytes/sec, 16 bit data width 40 pin data Modes 0, 1, 2, 3, or 4 and Multiword DMA modes 1 and 2 and Ultra DMA Pins 1, 2, and 3 are optional as well, as evidenced by some adapter cables that connect the drives to older PSUs. The ATA-3 specification was released in 1997 and was A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. The Where 30nS cycle time is 2 clock periods at ATA [IDE] is now being called PATA.
