SYNOLOGY HAT5310 NAS 20TB Plus Series SATA 3.5" Hard Drive

SYNOLOGY HAT5310 NAS 20TB Plus Series is a hard drive aimed at serious NAS configurations where you need a lot of space and 24/7 stability. The form factor is standard 3.5", so it fits without surprises in most NAS enclosures and server chassis. The 20TB capacity gives you serious volume for backup, media libraries, or work projects. It operates at 7200 rpm and uses a SATA3 6 Gb/s interface, so it is oriented toward constant, reliable data transfer, rather than short bursts like a typical desktop drive.

What you get: a large, NAS-oriented drive with an emphasis on endurance under sustained load. 20TB is more than enough for a serious home server or small office – you can keep years of archives, camera recordings, photos, video, and projects in one place. 7200 rpm helps with faster access to large files and more stable speeds during long copies – useful for overnight backup windows or RAID rebuilds. The 512MB cache buffers I/O peaks and reduces the need for constant “back-and-forth” seeking across the platters, which is noticeable with many small files and parallel requests. Thanks to SATA3 6 Gb/s, you can confidently combine it with almost any modern motherboard/NAS platform, without worrying about interface compatibility.

• The drive is a specialized NAS model, designed for operation in network storage systems and continuous 24/7 use.
• The large 20TB capacity allows you to store huge media collections, backups of several machines, or a multi-camera video surveillance archive.
• The 7200 rpm speed provides lower access times and more stable sequential speeds compared to slower 5400 rpm solutions.
• The SATA3 6 Gb/s interface guarantees wide compatibility with NAS devices and server motherboards, as well as sufficient throughput for a mechanical drive of this class.
• The large 512MB cache helps with frequent small operations and burst traffic, which is typical for multi-user access to a NAS.
• The standard 3.5" form factor and dimensions of 147 x 101.85 x 26.10 mm mean it will fit in almost any standard enclosure or NAS chassis.
• The 36-month warranty gives you peace of mind for long-term use in configurations critical to your data.

It is suitable if you are building or expanding a NAS for a home media server, small office, backup of several workstations, or video surveillance, where having a lot of space and reliability is more important than maximum IOPS performance. It is not the optimal choice if you are looking for a drive for the system partition of a gaming PC – an SSD is much more sensible there, while such an HDD is better as mass storage in the background.

The combination of 20TB capacity, 7200 rpm, large 512MB cache, and NAS orientation makes the SYNOLOGY HAT5310 Plus Series a very adequate solution for serious storage arrays, where you want a lot of space in few slots and long-term stability.
