What kind of hard drives do servers use?

Servers typically use high-performance hard drives, such as solid-state drives (SSDs) or hard disk drives (HDDs).

Here are some types of hard drives used in servers:

1. SSDs

Preferred for their fast read and write speeds, making them ideal for applications that require quick data access.

2. NVMe drives

The latest technology in server storage, providing higher performance and lower latency compared to traditional SSDs. They come in various form factors, including U. 2 (2.5").

3. SATA (Serial ATA)

The most common server hard disk drive interface today. It offers faster data transfer speeds than PATA, and it is more reliable.

4. SCSI (Small Computer System Interface)

A more advanced interface than SATA, and it is often used in high-performance servers.

5. SAS (Serial Attached SCSI)

A serial interface for connecting hard disk drives which is based on SCSI command sets. SAS interface operates at a rate up to 1,200Mb/sec. with the throughput up to 12 Gb/sec.

When buying a hard disk, you can consider things like: Storage capacity, Transfer speed, Security, Compatibility, Durability and portability.
