No, that's not accurate. Hard drives typically have two main connections: one for data transfer (usually a SATA or SAS cable) and one for power (a power cable). The data connection handles both reading and writing operations, as hard drives can read and write data on the same channel.
SATA cables.
Drives are linked by cables called SATA cables, these send data through the motherboard
Many newer systems don't have any ribbon cables at all. Ribbon cables were used for IDE drives, SCSI drives, and floppy drives. The number of cables will depend on the number of drives in the system (16 drives per SCSI cable, 2 per IDE cable, and 2 per floppy cable).
Small Computer System Interface (SCSI) cables are used to connect computers to certain devices such as hard drives, tape drives, printers, CD drives, and scanners.
IDE cables in computers are used to connect Hard Disk Drives and CD/DVD Drives to the motherboard. - Neeraj Sharma
It is called an optical drive because the mechanism for reading and writing information is optical (light) based - it uses lasers.
This is a data ribbon cable is used for computer drives, like hard disk drives, Optical disk drives, and floppy disk drives. They are also referred to as PATA cables. They connect to parallel ports consisting of 20 pins in one row, and 19 in the second, for a total of 39 pins. IDE cables are now considered old, having been largely replaced by SATA cables, which connect to newer drives which run at more RPM. The SATA system communicates more quickly that the PATA system using IDE cables.
To connect SAS drives to a SAS controller in an HP xw8600, you need to use the appropriate SAS cables, as SATA cables are incompatible with SAS connectors. Ensure that you have SAS breakout cables that have the correct connectors for both the SAS controller and the SAS drives. Connect the SAS drives to the breakout cable, and then attach the other end of the cable to the SAS controller. Make sure the drives are properly seated and the controller is configured to recognize them in the system BIOS.
They don't. Jumper cables are used to charge a car battery. Hard drives have no use for such a device.
becase they should
Raid level 5 supports reading and writing, but writing performance is slower than raid levels 0 and 1.Raid level 5 requires a minimum of 3 drives.
Notebook's use 2.5 hard drives and they have 44 pin connections 3.5 hard drives used 40 pin connections BUT they make adapters to use either or
