Seagate Exos X24 3.5" Internal Alternatives: 6 Similar Picks Compared

How alternatives compare to X24

Western Digital AV-GP 1TB 3.5-Inch Hard Drive

The WD AV-GP offers 1TB of storage, which is significantly less than the 12TB capacity of the Seagate Exos X24. It uses a 64MB cache and lacks helium sealing, relying on standard air-filled construction. This drive is designed for basic surveillance recording rather than high-performance data center workloads. You get a much smaller form factor and lower weight, but you sacrifice massive storage density and advanced power management features. It fits users who only need small capacity for simple recording tasks. It is not suitable for hyperscale deployments or applications requiring low latency and enhanced caching. Choose this if you prioritize budget and basic function over enterprise-grade reliability and high capacity.

Toshiba 14TB Enterprise 7200 RPM HDD (Renewed)

The Toshiba MG07ACA14TE provides 14TB of storage, exceeding the 12TB capacity of the Seagate Exos X24. It features a 256MB cache, which is larger than the Exos X24’s unspecified caching, and runs at 7200 RPM. Like the Exos X24, it uses helium sealing for robustness and leak protection. This drive is built for demanding server environments and enterprise NAS setups. You gain higher capacity and potentially faster rotational speeds, but you may find it heavier and larger in dimensions. It is ideal for users who need reliable, high-capacity storage for heavy workloads. It suits those who value proven enterprise reliability and helium-sealed design for large-scale deployments where maximum storage density is critical.

Western Digital RE 4TB 7200 RPM Hard Drive

The WD RE 4TB offers only 4TB of storage, which is much lower than the 12TB capacity of the Seagate Exos X24. It features a 64MB cache and runs at 7200 RPM. This drive is designed for sustained performance and reliability in small business servers rather than maximum capacity. You get consistent data throughput but sacrifice significant storage space. It is ideal for users who prioritize performance per drive over total capacity. It fits environments where moderate capacity is sufficient and reliability is key. It is not suitable for hyperscale data centers needing massive storage density. Choose this if you need reliable enterprise storage for specific workloads where 4TB is adequate and consistent performance matters more than high capacity.

Seagate Exos 7E8 6TB Enterprise Drive

The Seagate Exos 6TB provides 6TB of storage, which is half the capacity of the 12TB Exos X24. It features a 256MB cache and is designed for 24/7 server and NAS workloads. Like the Exos X24, it is built for enterprise reliability, but it offers less total storage. You get a specific 6TB capacity option with high workload tolerance, but you sacrifice the higher density of the X24. It fits users who need a specific capacity with proven enterprise reliability. It is ideal for expanding storage where 6TB per drive is sufficient. It is not suitable for users needing maximum storage density. Choose this if you require a smaller capacity drive with high reliability for 24/7 operation.

Seagate Exos X14 14TB Renewed Enterprise HDD

The Seagate Exos X14 14TB offers 14TB of storage, which is greater than the 12TB capacity of the Exos X24. It runs at 7200 RPM and uses SATA III interface. This drive is designed for high-capacity enterprise storage needs. You gain higher capacity and proven enterprise reliability, but it is a renewed product, which may affect warranty or condition compared to a new drive. It is ideal for users comfortable with recertified hardware to save costs while maintaining performance standards. It fits those needing large-scale deployments with high storage density. It is not suitable for users requiring brand-new units with full manufacturer warranty. Choose this if you prioritize capacity and value over new condition.

MFerraz 6TB Enterprise 7200 RPM Hard Drive

The MFerraz 6TB offers 6TB of storage, which is less than the 12TB capacity of the Seagate Exos X24. It features a 256MB cache and runs at 7200 RPM. This drive is designed for dependable 24/7 performance in standard drive bays. You get a solid option for expanding NAS storage where 6TB is sufficient, but you sacrifice the higher capacity and advanced features of the Exos X24. It is ideal for users needing reliable enterprise specs in a standard form factor. It is not suitable for hyperscale data centers requiring maximum storage density. Choose this if you need a specific 6TB capacity with high workload tolerance for NAS expansion where 12TB drives are not required.
