This article covers SEAGATE Schnittstelle: S-ATA 6 Gb.

Overview

The Seagate ST4000VN000 is a 4TB 3.5-inch internal hard drive designed for NAS use. It spins at 5900 RPM, features 64MB of cache, and connects via SATA 6Gb/s. This model has been a popular choice for home NAS users and small business backup systems, offering a good balance of cost and reliability. It is positioned as an entry-level to mid-range NAS HDD, suitable for bulk storage rather than high-speed access. With its 4TB capacity, the drive provides ample space for photo libraries, video archives, and PC backups. The lower rotational speed helps reduce noise and power consumption, making it a good fit for 24/7 operation in living rooms or small offices. However, users should be aware that the 5900 RPM speed results in slower sequential read/write performance compared to 7200 RPM drives. This is not a drive for frequent large file transfers or high-end creative workloads.

Compatibility Guide

The ST4000VN000 uses a standard 3.5-inch form factor and SATA 6Gb/s interface. It can be installed in any desktop PC case with a 3.5-inch bay or in a NAS enclosure that supports 3.5-inch drives. It is also backward compatible with SATA 3Gb/s ports, but performance will be limited to that interface speed. For RAID setups, it is best to use identical drives to avoid performance mismatches. Mixing drives with different cache sizes or rotational speeds can cause the array to run at the speed of the slowest drive.

Product Info

The Seagate ST4000VN000 was released around 2014 as part of the earlier NAS HDD series. While it has been superseded by the IronWolf line, it is still found in clearance sales or as open-box stock. The standard warranty is 2 years, but this varies by seller. In the current market, this drive sits at the entry-level tier for NAS storage. It does not match the newer IronWolf Pro in terms of workload rate or speed, but for basic file serving and backup, it remains a functional and inexpensive option.

Best Use Cases

File server or NAS backup drive: Ideal for long-term storage of large data volumes. Low power consumption and heat output make it suitable for always-on operation. Budget home NAS build: Use multiple units in RAID 1 or RAID 5 to get redundancy and capacity at a low cost. * Quiet PC secondary storage: 5900 RPM operation is noticeably quieter than 7200 RPM drives, perfect for silent builds. ## Alternatives
A direct competitor is the Western Digital Red 4TB (WD40EFRX), which also runs at 5900 RPM and has 64MB cache. The WD Red is known for better support of TLER (time-limited error recovery), which can be important for RAID compatibility in some enclosures. Another alternative is the Seagate IronWolf 4TB (ST4000VN008), which doubles the cache to 128MB and offers improved sustained transfer rates and a longer warranty. The ST4000VN000 is typically the cheapest option, but for mission-critical setups, the extra reliability and support of the newer models are worth the premium.

Things to Consider

Given the age of this model, even new-old-stock units may have been stored for years, which can affect reliability. The drive is not designed for 24/7 enterprise workloads; its annual failure rate is higher than current NAS-specific drives. Also, it uses Advanced Format 4K sectors, so older operating systems or NAS firmware may experience performance issues without proper alignment. If the price difference is small, newer alternatives like the Seagate IronWolf offer better endurance and longer warranty coverage. Avoid buying used drives, as the risk of failure increases. Always purchase from a reputable seller who provides a return policy.
