HPE EH000900JWCPH 900GB 15K RPM SAS 12GBPS SFF SC Hard Drive New

SAS (Serial Attached SCSI) is a technology used for connecting and communicating between computer storage devices, such as hard drives, solid-state drives (SSDs), and tape drives, and the system's motherboard or host bus adapter (HBA). SAS is an evolution of SCSI (Small Computer System Interface) technology that uses a serial interface instead of parallel, which provides several advantages over its predecessor, including higher data transfer rates, longer cable lengths, and better scalability.

SAS is designed for enterprise-level storage applications that require high-speed data transfer rates, reliability, and high availability. SAS interfaces can operate at different speeds, including 3Gbps, 6Gbps, 12Gbps, and even up to 24Gbps. The technology also supports multiple protocols, including SCSI, ATA, and SATA, which allows for greater flexibility in connecting different types of devices.

One of the key features of SAS is its ability to support multiple devices on a single bus. This is achieved through the use of expanders, which allow multiple SAS devices to be connected to a single SAS port. This feature is particularly useful in enterprise-level storage systems that require a large number of drives to be connected to a single host.

SAS technology also provides several other features, such as hot-swappable drives, which means that a drive can be replaced or removed from the system without shutting it down. SAS also supports multiple port configurations, which allows for redundant connections and increased availability in the event of a failure.

Small Form Factor (SFF) refers to the size and shape of a computer component, such as a hard drive or a motherboard. The term is used to describe components that are smaller than the standard form factor for that type of component.

In the context of hard drives, SFF refers to hard drives that are smaller than the standard 3.5-inch or 2.5-inch form factors. SFF hard drives typically have a diameter of 2.5 inches and a thickness of 7mm or 15mm, making them much smaller than standard hard drives. This small size makes SFF hard drives ideal for use in compact devices, such as laptops and small form factor desktop computers.

SFF hard drives use the same interface as standard hard drives, such as SATA or SAS, which means that they can be easily integrated into existing systems. They also offer similar performance to standard hard drives, with some SFF hard drives even offering higher data transfer rates and faster access times.

In addition to hard drives, SFF form factors are also used in other computer components, such as motherboards and power supplies. SFF motherboards, for example, are designed to fit into smaller computer cases, such as mini-ITX and micro-ATX cases, while still offering the same features and performance as standard ATX motherboards.

SAS (Serial Attached SCSI) and SATA (Serial ATA) are two commonly used interfaces for hard drives, with both offering advantages and disadvantages depending on the intended use case. Here is a comparison of SAS and SATA interfaces:

• Performance: SAS interfaces generally offer faster data transfer rates than SATA interfaces. SAS supports higher RPM (rotations per minute) drives and can provide more bandwidth, resulting in faster read and write speeds.
• Reliability: SAS interfaces are designed for high reliability and availability, making them ideal for use in enterprise-level storage systems. SAS supports features such as dual-porting, multipathing, and hot-swapping, which are not supported by SATA.
• Scalability: SAS interfaces support more devices per port than SATA, which makes them more scalable in large storage systems.
• Compatibility: SATA interfaces are more widely supported than SAS interfaces, as SATA is more commonly found in consumer devices such as desktops and laptops. Most motherboards and storage systems support SATA natively, while SAS may require additional hardware and software support.
• Cost: SATA interfaces are generally less expensive than SAS interfaces, making them more cost-effective for consumer-level storage needs. SAS drives and systems tend to be more expensive due to their high reliability and availability features.
