Hard drives have an important role in the life of enterprises. An HDD is an important part of a storage system, responsible for answering requests, providing access to data, and storage. It is crucial that the hard disks used by enterprises are reliable, durable, perform well and fast, have excellent data integrity and can handle the higher workload of an organization. Especially in cases where vital data is stored, for example in the case of a database, it is essential that the drives are able to handle large amounts of data reliably - as in with a minuscule chance of outage or critical failure. Another important factor related to reliability is the data integrity. Even a minimal corruption of data can have dire consequences, for example critical loss of data. HDDs meant for enterprise use, should also be able to handle a high amount of work - while HDDs meant for desktops are mostly used within work hours, so 8 hours a day and 5 days per week, the hard disk drives in storage networks run 24/7. This is why the performance of the drive (such as the rotational speed) is a good idea to consider when selecting your next HDD.
 Serial Attached SCSI (SAS) is the logical evolution of SCSI including its long-established software advantage and the serial physical connection interface. With enterprise storage requirements escalating and becoming more complex factors such as larger capacity greater density security scalability and accessibility are more critical than ever. Enterprise data centers must be online all the time fulfill requests from numerous users simultaneously allow for constant growth and expansion and be maintained while in operation. Serial Attached SCSI (SAS) meets all these demands while providing the highest performance.
 HPE offers different solid-state drive (SSD) solutions to meet different customer needs. Enterprise SSDs as a class are unique to client or consumer-based SSD in terms of reliability, performance and architecture. While consumer-based SSDs, such as those utilized in notebooks are designed with a focus on consumer-based workloads, rigidity and battery life, enterprise-class SSDs are designed around enterprise application I/O (input/output) requirements with the primary attribute focus being on random I/O performance and reliability.
