Enterprise-ready

The HAS5300 series drives leverage the low-latency SAS protocol. When paired with high-performance and highly scalable Synology HD, SA, or UC series solutions, they ensure that mission-critical workloads always have access to dependable and fast storage.

Back to peak performance faster

Building on two decades of storage expertise, Synology HAS5300 drives run on firmware optimized for critical workloads that matter. They allow Synology systems to repair degraded RAID arrays up to 27% faster than similar-class and capacity drives.

Hard drives designed for SynologySee how Synology hard drives deliver reliability, consistent performance, and simplified system management through deep hardware-software integration.

Validation

Rigorous tests and compatibility verification ensure maximum reliability on Synology systems, even while handling the most extreme workloads.

Synology Enterprise Series SAS drives undergo over 1,000 stress test cycles and and more than 200,000 hours of cumulative testing to ensure maximum reliability

Dependable

A 2.5 million-hour MTBF, support for up to 550 TB per year workloads, and persistent write cache technology come together to safeguard data integrity.

One-click firmware upgrades

Automatic firmware update notifications and one-click installation through DSM minimize maintenance workload and reduce the chance of oversights.

Faster issue diagnostics and resolution

Deploying Synology hard drives has led to nearly 40% fewer storage-related incidents and more efficient issue resolution for our users.

Notes:Mean Time Between Failure (MTBF) is not an estimate or guarantee of product life; it is a statistical value related to mean failure rates for a large number of products and may not accurately reflect actual operation. Actual operating life of the product may be different from the MTBF.The warranty period starts from the purchase date as stated on the receipt of purchase.Maximum sustained data transfer speed of HAS5300-16T drives.Performance testing was conducted by Synology using 12 drives on an SA3600, configured using RAID 5 and a Btrfs file system, against similar capacity (12TB) and class (Enterprise) drives. Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured.Among the HAS5300 series drives, over 200,000 hours of tests have been conducted on SAS-compatible Synology devices to ensure compatibility and performance expectations of these drives when used on Synology solutions.Based on Synology customer support statistics over the past few years, the use of validated drives results in nearly 40% less storage-related issues and faster issue diagnostics and resolution.Product images are for illustrative purposes only.
