HITACHI HUS724020ALA640 2TB 7200 RPM SATA 3.5in Hard Drive - Reliable

In this review the reviewer finds the HITACHI HUS724020ALA640 is a sensible choice for users who need reliable, high-capacity internal storage without paying for brand-new enterprise drives. The bottom line: this renewed 2TB HGST Ultrastar model delivers solid performance at 7200 RPM and a hefty 64MB cache, and its long MTBF makes it a dependable option for bulk storage, backups, and legacy desktop or server upgrades. This review focuses on who benefits most and what to expect from a professionally inspected, renewed unit.

Key Features

• 2TB capacity: Provides ample space for large media libraries, disk images, and file backups without frequent juggling of files.
• 7200 RPM spindle speed: Offers faster sustained transfer rates than typical 5400 RPM drives, improving load times for applications and file transfers.
• SATA 6Gbps interface: Ensures compatibility with modern SATA controllers and supports higher throughput on capable systems.
• 64MB cache: Smooths burst transfers and helps with multitasking workloads by buffering small reads and writes.
• HGST Reliability: Built on the Ultrastar 7K4000 platform with an MTBF of around 2.0 million hours, aimed at long-term use in desktops and entry-level servers.

Who It's For

This drive suits desktop users, small office servers, and system builders who want a cost-effective, high-capacity internal hard drive for mass storage, media editing scratch space, or archival backups. Anyone refurbishing older systems or populating RAID arrays with reliable spindles will value the Ultrastar lineage and 7200 RPM performance.

Those who should look elsewhere include users who require NVMe SSD speeds for operating system responsiveness or workloads that demand very low latency. Also, people seeking brand-new factory-sealed hardware with full retail warranty may prefer a new retail drive instead of a professionally renewed unit.

Frequently Asked Questions

Is this drive compatible with modern desktops?

Is this suitable for a NAS or RAID array?
It can be used in entry-level NAS or RAID setups for bulk storage, though enterprise-class drives may be preferable for always-on, heavy-duty multi-bay systems.
