High-Capacity Archive Drive

The Seagate Archive HDD ST8000AS0022 is an 8TB 3.5-inch internal hard drive built for bulk data storage. Its 5900 RPM spindle and 128MB cache suit write-once, read-many workloads such as media libraries, backups and long-term archiving. The SATA 6.0Gb/s interface connects to standard desktop motherboards and external enclosures. Shingled magnetic recording optimises areal density for cost-effective capacity.

Compatibility Checklist

Verify your system has a free 3.5-inch drive bay and a spare SATA data port on the motherboard or controller card. A SATA power connector from the power supply is required. The drive measures 146.99mm long, 101.60mm wide and 26.10mm high; confirm clearance in compact cases. Host-aware SMR operation works with modern operating systems, but older RAID controllers or BIOS implementations may not support ZAC commands.

Upgrade Context

This drive replaces smaller-capacity desktop hard drives when a single-volume archive is preferred over spanning multiple disks. The jump is worthwhile when 8TB consolidates several older drives, reducing power draw, noise and cabling. It is not suited for primary operating-system boot drives, heavy random-write databases or applications demanding sustained high IOPS. Buyers needing low-latency transactional performance should consider alternative storage technologies.

Questions about this item

Does the ST8000AS0022 include cables, brackets or mounting screws, or must they be purchased separately?

The drive is supplied as a bare 3.5-inch unit; SATA data and power cables plus mounting screws are not included and must be sourced separately.

Which capacity and cache combination should I choose from the Archive HDD line for maximum storage?

This model provides 8TB capacity with 128MB cache, the highest capacity offered in the Archive HDD series.

How does the 600MB per second burst rate translate to real-world throughput on a SATA 6.0Gb/s port?

The 600MB per second figure is an instantaneous burst limit; sustained transfers are governed by the 5900 RPM platters and SMR architecture, typically well below the burst peak.
