Synology introduced the Plus series drives

HAT3300 drives are intended for installation in NAS servers of the Plus series and below, which were manufactured after 2018.

Synology has introduced its first series of HAT3300 SATA HDDs, dedicated to the Plus series, specifically designed to meet the reliability, durability and continuous data storage performance requirements of entry-level and mainstream Synology systems1.

The new drives have undergone thorough performance testing with Synology systems. Testing confirmed reliable and consistent performance in multi-user environments. The Plus series joins the existing line of Enterprise hard drives and brings the proven quality of Synology hard drives to users in less demanding environments.

Key features of Synology Plus series hard drives include:

  • Reliable continuous operation: with 1 million hours mean time between failures (MTBF)2 and 180 TB annual workload3 provide up to three times more endurance than conventional hard drives.
  • Tested for maximum reliability: more than 300,000 hours of rigorous compatibility and performance testing in stressful situations ensures smooth operation even under loads with a larger number of users.
  • System software updates: Users can update disk firmware directly from Synology’s DiskStation Manager (DSM). Thus, there is no need to stop the system, remove disks and perform manual updates.
  • One stop support: customers access technical support directly through their Synology account.
  • Four different capacities: Plus series hard drives are available in 4 TB, 6 TB, 8 TB and 12 TB storage models to suit different needs and budgets.

“The drives are designed for use in Synology systems and are ideal for users who need reliable storage while also receiving convenient system software updates within the DSM operating system and a single point of contact for support for all system issues,” said Peggy Weng, product manager at Synology.

Synology Plus series hard drives offer the perfect balance between reliability and convenience for home and small office users, providing a reliable solution to meet their storage needs, whether for file sharing, data backup or security camera footage storage.

Full list of technical specifications for the Plus series

  1. Take a look compatibility listfor supported storage systems.
  2. Mean time between failures (MTBF) is not an estimate or guarantee of product life. This is a statistical value associated with average failure rates for a large number of products and may not accurately reflect actual performance. Actual product life may differ from MTBF.
  3. A workload estimate is defined as the amount of data written, read, or verified by commands from the host system.
  4. “3.5-inch” describes the form factor of hard drives. It does not indicate the physical size of the drives.
  5. Definition of capacity: When describing hard disk capacity, a terabyte (TB) is defined as 1,000,000,000,000 bytes. However, computer operating systems report storage capacity in powers of 2 for the definition 1 GB = 230 = 1,073,741,824 bytes. This means that operating systems will report less available memory capacity. Available storage capacity will also vary based on file size, formatting, settings, software and operating system used. Actual formatted capacity may vary.
  6. The warranty period starts from the date of purchase as stated on your proof of purchase. read moreabout our limited product warranty policy.
