There are several common types of hard drive PCB connectors. Some of these include:
SATA connector: This is a popular connector used in modern hard drives. It is a small, flat connector with seven pins.
IDE connector: This is an older connector that was commonly used in older hard drives. It is a wide, flat connector with either 40 or 80 pins.
SCSI connector: This is a high-speed connector that was commonly used in enterprise-level hard drives. It is a large, rectangular connector with either 50 or 68 pins.
SAS connector: This is a newer connector that is commonly used in high-performance hard drives. It is a small, flat connector with either 29 or 34 pins.
M.2 connector: This is a small, compact connector that is commonly used in solid-state drives (SSDs). It has a variety of pin configurations depending on the specific drive.
These are some of the most common types of hard drive PCB connectors, but there are others as well. The specific type of connector used will depend on the type and age of the hard drive in question.
