WD Ultrastar DC HC590 0F65672 — 26TB SED Data Center HDD

26TBSATA 6GB/sTCG SEDCMR · 512 MB

The Western Digital Ultrastar DC HC590 0F65672 is a 26TB data-center-class 3.5-inch SATA hard drive with hardware TCG self-encryption (SED), built for hyperscale and enterprise storage. Using an industry-first 11-platter CMR design with HelioSeal helium sealing and OptiNAND, it spins at 7200 RPM with a 512 MB cache over SATA 6GB/s. Identified by part number 0F65672 (EAN 0829686009172, model WUH722626ALE6L4), it is rated for 550TB/year workloads and a 2.5-million-hour MTBF. Typically in stock with fast delivery across Cyprus.

Compatibility & Setup
This is a bare internal 3.5-inch SATA drive for servers, RAID controllers and data-centre chassis that support 26TB drives. It is a TCG Encryption self-encrypting drive: hardware AES encryption is always active, and to manage authentication keys and Instant Secure Erase you need a host, HBA or RAID controller with TCG Opal/Enterprise support — used without key management it still works as a standard SATA drive. No mounting screws or cables are included, and it ships unformatted for initialisation in your host.

Best For

✓Hyperscale and enterprise data centres
✓Servers and RAID/JBOD arrays
✓Security-sensitive storage requiring SED
✓24/7 read-intensive workloads
✓Backup, archival and cold-tier storage
✓Dense multi-bay high-capacity chassis

Key Features

 
Industry-first 11-platter CMR
A CMR (conventional magnetic recording) 11-disk HelioSeal platform reaches 26TB while keeping consistent write performance and RAID compatibility — no SMR shingled-write penalty.
 
TCG self-encryption + Secure Erase
Hardware AES self-encryption (SED) with TCG support and Instant Secure Erase lets you cryptographically wipe the drive in seconds for secure decommissioning and compliance.
 
Data-center reliability
Rated for 550TB/year workloads, a 2.5-million-hour MTBF and 1-in-10^15 error rate, with OptiNAND and ArmorCache protecting data and cache during power loss.
 
5-year limited warranty
Backed by a 5-year limited warranty for data-centre-grade assurance in mission-critical, always-on deployments.

Frequently Asked Questions

What does TCG SED encryption mean on the 0F65672?
It is a hardware self-encrypting drive: an on-board AES engine encrypts all data automatically. With a TCG Opal/Enterprise-capable controller you can set authentication keys and use Instant Secure Erase to wipe the drive cryptographically in seconds. Without key management it still works as a normal SATA drive.
Is the HC590 a CMR or SMR drive?
It uses CMR (conventional magnetic recording) on an 11-platter design, so it offers consistent write performance and full RAID compatibility — unlike SMR drives, which can slow under sustained writes.
Does it work in a standard server or RAID array?
Yes. It is a SATA 6GB/s drive for servers, RAID controllers and data-centre chassis that support 26TB drives. Confirm firmware support for high-capacity drives and, if you need managed encryption, TCG Opal/Enterprise support.
What do I need to know before buying?
It is a bare internal 3.5-inch SATA SED drive with no mounting kit or cables, and it ships unformatted for initialisation in your host. Typically in stock with fast delivery across Cyprus.
Singular Expert Insight
The Ultrastar DC HC590 is Western Digital’s data-centre flagship, a notch above the WD Gold line: the 0F65672 adds TCG self-encryption (SED) for security-sensitive and compliance-driven deployments, while sharing the same 550TB/year workload and 2.5-million-hour MTBF. If you do not need hardware encryption, the non-SED HC590 or a WD Gold drive costs less; if you are scaling a secure array, pair it with matching drives from our enterprise/server HDD range. For latency-critical tiers, an enterprise SSD is the complement.

Buyer’s Guide

Buy it if
You need 26TB per bay with hardware TCG SED encryption
You run secure or compliance-driven data-centre storage
You want 550TB/yr workload and a 5-year warranty
Skip it if
You do not need self-encryption — a non-SED drive costs less
Your controller cannot address 26TB drives
You need sub-millisecond latency — choose an enterprise SSD
Also consider
WD Ultrastar DC HC590 non-SED for lower cost
WD Gold 26TB (WD261KRYZ) for server use without SED
Seagate Exos X24 24TB SED as a SAS alternative
