Seagate IronWolf Pro 4TB

Top performance and maximum reliability

The IronWolf Pro series is designed for always-on, always accessible operation required in NAS systems. Advanced AgileArray technology makes it extremely reliable and responsive. The device provides easy scalability with RAID support and features advanced power management that saves energy and delivers the right power at the right time.

Designed for commercial and corporate use

Both its parameters and name make it clear that the Seagate IronWolf PRO series is designed for true professionals and is ideal mainly for large corporations and other big enterprises. The SATA III interface provides high speeds reaching 600 MB/s, but the disk is also backward compatible with SATA II and SATA standards. The platters rotate at 7200 rpm and there is a 128 MB cache for better responsivity.

Reduced drive vibration

IronWolf drives are equipped with special sensors that reduce drive vibrations to ensure consistent performance and reliable operation even in multi-bay NAS units. Meanwhile, the RAID performance is optimised to maximise responsiveness and uptime with NAS-aware Error Recovery Control.

Active data protection

IronWolf Pro is equipped with advanced features to keep your storage solution running smoothly and extend its service life. Synology DiskStation Manager 6.1 automatically analyses the disk, updates you on the state of your drive, and offers recommendations for improving your data security.

Multiple user access

NAS storage is optimised for multiple-user access 24 hours a day, 7 days a week. The unit can handle a workload of up to 300 TB per year. With remote access, your files are always available and easy to back up or share from almost anywhere.
