SAS vs. SATA is a key consideration when selecting server storage, as the two interfaces differ in performance, reliability, fault tolerance, and cost. Both connect hard disk drives and solid-state drives to server controllers, but they are designed for different requirements and workloads. This article compares SAS and SATA in terms of command processing, fault […]
SAS (Serial Attached SCSI) is a serial point-to-point communication standard for connecting storage devices in server and enterprise storage systems. SAS supports, among other features, full-duplex data transmission, SAS expanders, and, with corresponding enterprise drives, redundant data paths through dual-port connections. When evaluating enterprise storage for database servers, virtualization hosts, or RAID arrays, data sheets […]
A JBOD — “Just a Bunch of Disks” — is a disk enclosure architecture that exposes individual drives directly to a host system or external storage controller without performing hardware RAID operations. The key difference between JBOD and RAID lies in where the storage logic and redundancy are implemented. Unlike intelligent storage arrays with onboard […]
RAID combines multiple drives into a logical volume — but which configuration matches your requirements? The choice between RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10 determines usable capacity, performance, rebuild duration and failure tolerance. This article explains how each RAID level works, which deployment scenarios they serve, and how to weigh […]
