HDD Synology 4TB 3.5" SATA HAT3300-4T

The Synology HAT3300-4T is a 4TB 3.5" SATA internal hard drive engineered for network-attached storage (NAS) environments. With a 5400 RPM spindle speed and a SATA interface, this HDD balances capacity and energy efficiency for continuous operation. Designed by a brand focused on storage solutions, it supports sustained read/write activity and is suitable for multi-drive NAS arrays where reliability and low power draw are priorities.

Advantages

The drive provides a large 4 TB capacity in a 3.5-inch form factor, enabling significant on-site storage without occupying multiple bays. Its 5400 RPM design reduces rotational noise and power consumption compared with higher-speed drives, which helps maintain lower operating temperatures in enclosed NAS chassis. The SATA interface ensures broad compatibility with most consumer and small-business NAS systems, and the model is optimized for 24/7 operation to support continuous access and background tasks.

Suitable for

• Home and small office NAS systems for centralized file storage
• Media libraries and streaming servers storing video and audio collections
• Backup repositories and snapshot storage within multi-bay enclosures
• Archive and cold storage where capacity and low power usage are important

Key specifications

• Capacity: 4096 GB
• Form factor: 3.5-inch
• Rotational speed: 5400 RPM
• Interface: Serial ATA (SATA)
• Designed for continuous 24/7 operation

How to use

Install the drive into a compatible 3.5" bay on your NAS or desktop that supports SATA connections. Mount the drive securely with appropriate screws or trays, connect the SATA data and power cables, and power on the system. Use the NAS management software to initialize, format, and add the drive to an existing volume, RAID array, or as a standalone disk. Monitor drive health and temperatures periodically through the NAS administration interface to ensure continued reliable operation.

Usage recommendations

For optimal longevity and performance, operate the drive in a well-ventilated NAS chassis with active cooling, keep firmware of the host NAS up to date, and configure regular backups and drive-health checks. When deploying multiple drives, use RAID levels appropriate to your redundancy and performance needs and avoid mixing drives with significantly different speeds or ages in the same array.
