Which existed before ATA drives?
scsi
Which ata standard allows for serial ata and serial attached scsi to coexist in the same system?
ATA/ATAPI-7 -Serial SCSI standard is compatible with serial ATA drives in the same system
What terms does not describe parallel ATA devices?
SCSI
What is sata ide scsi hard drive?
IDE is an older disk communication protocol. (http://en.wikipedia.org/wiki/AT_Attachment) SATA is perhaps the newest, it stands for "serial ATA). SCSI stands for "small computer system interface" and allows for connection of more than just disk drives.
What are 3 samples of a Hard disk?
SATA , ATA and SCSi
What are three common standards CD drives use to interface with a system?
Geoff Housers mom The three common interface standards for a CD drive are EIDE (aka parallel ATA), serial ATA, and SCSI interface with a host adapter. You can also hook up a portable or external drive via USB, Fire Wire, or a SCSI port.
Which ata standard allows for serial ata and serial attached scsi to coexsist in the same system?
ATAPI-7
How do you make 3 Partitions on hard disk?
sata,ata,and scsi
How many pins does a PATA cable have that supports ATA-5 and UDMA66?
A PATA (Parallel ATA) cable that supports ATA-5 and UDMA66 typically has 40 pins. This 40-pin connector is used to connect devices like hard drives and CD-ROM drives to the motherboard. Additionally, there is a 80-wire version of the cable that improves data transfer rates while maintaining the same 40-pin connector.
What are the CD ports on computers called?
Internal CD ROMs and DVD ROMs plug into either SATA, ATA (PATA), or SCSI sockets. External drives plug into USB, E-SATA, or Firewire sockets.
Name three ways a CD drive can interface with a motherboard?
A CD drive can interface with a mother board using an EIDE, SATA or SCSI interface.
What is difference between ide sata and scsi hard disk?
For years the parallel interface has been widely used in storage systems. The need for increased bandwidth and flexibility in storage systems made the SCSI and ATA standards an inefficient option. A parallel interface is a channel capable of transferring date in parallel mode - that is transmitting multiple bits simultaneously. Almost all personal computers come with at least one parallel interface. Common parallel interfaces include SCSI and ATA. SCSI(sku4zē) Short for small computer system interface, a parallel interface standard used by Apple Macintosh computers, PCs and many UNIX systems for attaching peripheral devices to computers. Nearly all Apple Macintosh computers, excluding only the earliest Macs and the recent iMac, come with a SCSI port for attaching devices such as disk drives and printers. SCSI interfaces provide for data transmission rates (up to 80 megabytes per second). In addition, you can attach multiple devices to a single SCSI port, so that SCSI is really an I/O bus rather than simply an interface. ATA(Also known as IDE) is a disk drive implementation that integrates the controller on the disk drive itself. ATA is used to connect hard disk drives, CD-ROM drives and similar peripherals and supports 8/16-bit interface that transfer up to 8.3MB/s for ATA-2 and up to 100MB/s (ATA-6). So, what do parallel interfaces have to do with SAS (Serial Attached SCSI) and SATA (Serial ATA)? A lot, actually. It is the architectural limitations of the parallel interfaces that serial technologies like SAS and SATA address. In contrast to multiple parallel data stream, data is transmitted serially, that is in a single steam, by wrapping multiple bits into packets and it is able to move that single stream faster than parallel technology. Serial Attached SCSI (SAS)Abbreviated as SAS, Serial Attached SCSI, an evolution of parallel SCSI into a point-to-point serial peripheral interface in which controllers are linked directly to disk drives. SAS is a performance improvement over traditional SCSI because SAS enables multiple devices (up to 128) of different sizes and types to be connected simultaneously with thinner and longer cables; its full-duplex signal transmission supports 3.0Gb/s. In addition, SAS drives can be hot-plugged. Serial ATA (SATA) Often abbreviated as SATA, Serial ATA is an evolution of the Parallel ATA physical storage interface. Serial ATA is a serial link - a single cable with a minimum of four wires creates a point-to-point connection between devices. Transfer rates for Serial ATA begin at 150MB/s. Starting with SATA, it extends the capabilities of ATA and offers transfer rates starting at 150MB/s and, after years of development, has moved to the mainstream of disk interfaces. The successor the SCSI interface is SAS at speeds of up to 3Gb/s. Additionally, it also addresses parallel interface issues such as drive addressability and limitations on the number of device per port connection. SAS devices can communicate with both SATA and SCSI devices (the backplanes of SAS devices are identical to SATA devices). A key difference between SCSI and SAS devices is the addition in SAS devices of two data ports, each of which resides in a different SAS domain. This enables complete failover redundancy. If one path fails, there is still communication along a separate and independent path. Cables & Connectors Another big advantage of SATA over ATA is the cabling and connectors. The serial interface reduces the amount of wires needed to transmit data, making for much smaller cable size and making it easier to route and install SATA devices. The IDE cables used in parallel ATA systems are bulkier than Serial ATA cables and can only extend to 40cm long, while Serial ATA cables can extend up to one meter. In addition to the cabling, a new design of connectors is also used that reduces the amount of crosstalk between the wires, and the connector design also provides easier routing and better air flow. The Benefits of SAS & SATA in Storage Serial interfaces offer an improvement over older parallel SCSI (with a serial version) in storage applications and environments. These benefits include better performance, better scalability, and also better reliability as the parallel interfaces are at their limits of speed with reliable data transfers. SAS and SATA drives can also operate in the same environment while SCSI and ATA cannot. For example, using faster SAS drives for primary storage and offloading older data to cheaper SATA disks in the same subsystem, something that could not be achieved with SCSI and ATA.
