4 Common Types of Hard Drives

4 Common Types of Hard Drives Are you looking for a hard drive for your Dell PowerEdge Server? You first need to understand the following four different types of Dell Poweredge Hard drives available to meet your storage requirements without any hassles.

1. SAS (Serial Attached SCSI) It is a communication protocol, which is most commonly employed in Enterprise hard drives and tape drives. Serial Attached SCSI us a pointto-point serial protocol that swaps the older based parallel SCSI bus technology. It makes use of the general SCSI command set and has additional connections through the top of the SATA connection.

Essentially, it is popularly known as a hybrid between SAS and SATA.

2. SATA (Serial ATA) These hard drives are base hard drives in Dell PowerEdge servers that are designed to swap the older parallel ATA (PATA) standard. These Dell Poweredge hard drives are known to offer more than a few benefits over the older interface, including: •

• • •

Trimmed down size of the cable and cost since there are seven conductors rather that forty More proficient transfer by means of an I/O queuing protocol More rapidly data transfer with the help of higher signaling rates Native hot swapping On smaller servers with a controller, they can still be cabled for the reason that such systems will not have a backplane. Cabled hard drives are not hot swappable.

3. SSD (Solid-State Drive) It is a device to store data and makes use of an integrated circuit assembly as a memory for the purpose of storing data persistently.

This technology makes use of an electronic interface, which is attuned with customary block I/O (input/output) hard disk drives. SSDs don’t make use of any sort of moving parts that differentiates them from conventional magnetic disks like hard disk drives that are electromechanical devices including spinning disks and movable read/write heads.

4. Near Line SAS These are enterprise SATA 3.5IN drives with the media, head, SAS interface, and rotational speed of customary enterprise-class SATA drives with the completely competent SAS interface typical for classical SAS drives.
