WD Ultrastar DC HC580 - 3.5" Enterprise HDD Variants
About WD Ultrastar DC HC580 - 3.5" Enterprise HDD
The Ultrastar DC HC580 is WD's latest mainstream enterprise hard drive, available in 22TB and 24TB. It achieves the highest areal density in the Ultrastar lineup at 1,210 Gbits/sq. in. (24TB model) using improved EAMR and a 10-disk helium-sealed design with 2.4TB per platter.
Enterprise Specs
7,200 RPM, 512MB cache, CMR with EAMR, available in SATA 6Gb/s and SAS 12Gb/s. Workload rating is 550TB/year with a 2.5 million hour MTBF and 5-year warranty. Helium-sealed with OptiNAND and ArmorCache. Available in both 4Kn and 512e sector formats.
Sustained transfer rate is 298 MB/s on the 24TB model. Idle power is 5.5W on SATA, giving the 24TB the best power efficiency in the Ultrastar lineup at 0.23 W/TB idle.
Drive Security Variants
The last character of the model number indicates the security mode:
- SE (Base) -- No encryption, sanitize overwrite only. Available on both SATA and SAS. SATA models include ATA Security Feature Set as standard.
- SED (Self-Encrypting Drive) -- Hardware AES-256 encryption with TCG Enterprise protocol. Available on both SATA and SAS.
ISE and SED-FIPS variants were offered on earlier Ultrastar generations (HC520-HC550) but are not available on the HC560 and later.
Current Generation
As the newest Ultrastar, the HC580 commands a retail premium and is not yet widely available on the used market. For homelabbers buying new, the 24TB model offers the most storage per slot and the best power efficiency in the lineup. For those building on a budget with used drives, the HC550 (18TB) or HC570 (22TB) are more cost-effective per terabyte until the HC580 enters the secondary market in volume.
The Ultrastar Lineup at a Glance
All Ultrastar DC models share the same core specs: 7,200 RPM, 550TB/year workload, 2.5M hour MTBF, 5-year warranty, helium-sealed, SATA and SAS options. The differences are capacity, cache size, recording technology, and power efficiency. Newer generations pack more storage per drive while using less power per terabyte.
Best for: New-build NAS and storage servers where maximum density per slot and power efficiency justify buying at retail pricing.
Avoid if: You are building on a budget. Used HC550 or HC570 drives offer better value per terabyte until the HC580 hits the secondary market.
