Description
This item is brand-new, factory sealed.
Engineered for Demanding Workloads in Enterprise Environments
Synology HAS5300 is designed to meet the capacity, efficiency, and reliability needs of modern enterprise deployments. Built to handle workloads up to 550 TB per year, it empowers host systems to serve large pools of concurrent clients. With a 2.5 million-hour MTBF1 and backed by Synology's 5-year limited warranty2, HAS5300 meets the highest standards of dependability.
Perfect for scalable and high-availability systems
Synology HAS5300 SAS hard drives are specifically developed and tested to provide tight integration with our SA, HD, and UC lines of storage systems3. Enabling your applications to take full advantage of the bandwidth available, they are the ideal choice for high-capacity, mission-critical workloads that require 24/7 operation.
Optimized firmware and integration with Synology's DiskStation Manager (DSM) operating system running on Synology storage solutions result in up to 19% faster RAID array repair speeds4, greatly reducing the time the system spends in a degraded state.
Maximum durability and strong data protection
Rated for a 550 TB per year workload at a 2.5 million hours MTBF1, HAS5300 series drives are a safe and reliable choice for any critical data storage application. Persistent write cache technology bolsters data integrity protection and enhances overall write performance.
Over 200,000 hours of validation and stress testing with Synology systems guarantee interoperability for each HAS5300 drive, ensuring maximum reliability on Synology solutions under even the heaviest workloads.
Combined with backup and replication solutions running on Synology DSM, HAS5300 series SAS HDDs provide an additional layer of protection.
Integrated maintenance
Using Synology drives and host systems simplifies IT deployment. HAS5300 series drives are backed by Synology's 5-year limited warranty, providing you with long-term support for your entire system.
Drive firmware update capability within DSM reduce required maintenance while increasing your systems' service availability.
