WD Ultrastar DC HC590 0F59373 — 24TB SED SAS HDD

24TBSAS 12GB/sTCG SEDCMR · 512 MB

The Western Digital Ultrastar DC HC590 0F59373 is a 24TB data-center-class 3.5-inch hard drive with a native SAS 12GB/s interface and hardware TCG self-encryption (SED), built for secure, high-availability enterprise storage. Its HelioSeal helium-sealed CMR platform with OptiNAND spins at 7200 RPM with a 512 MB cache and delivers up to 298 MB/s. Identified by part number 0F59373 (EAN 0829686009042), 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 drive with a SAS 12GB/s interface — it requires a SAS controller, HBA or SAS backplane and will NOT connect to SATA-only motherboard ports (SAS ports accept SATA drives, but not the reverse). It is a TCG self-encrypting drive: hardware AES encryption is always active, and to manage keys and Instant Secure Erase you need a host or controller with TCG Opal/Enterprise support. No mounting screws or cables are included, and it ships unformatted for initialisation in your host.

Best For

✓Hyperscale and enterprise data centres
✓SAS servers, RAID controllers and JBOD
✓Security-sensitive storage requiring SED
✓24/7 high-capacity bulk storage
✓Dual-port redundant-path SAS arrays
✓Dense multi-bay high-availability chassis

Key Features

 
Native SAS 12GB/s dual-port
A SAS-3 12GB/s interface with dual-port capability provides redundant data paths and high throughput for enterprise servers and high-availability JBOD arrays.
 
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.
 
CMR + OptiNAND reliability
A HelioSeal CMR (conventional magnetic recording) platform with OptiNAND and ArmorCache protects data and cache during power loss — no SMR shingled-write penalty.
 
Data-center endurance
Rated for 550TB/year workloads and a 2.5-million-hour MTBF, backed by a 5-year limited warranty for continuous 24/7 duty.

Frequently Asked Questions

Will the 0F59373 work in a SATA port?
No. It is a SAS 12GB/s drive and needs a SAS controller, HBA or SAS backplane. SAS ports can host SATA drives, but SATA-only ports cannot run a SAS drive — check your server or RAID controller before ordering.
What does TCG SED encryption mean?
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.
Is the HC590 a CMR or SMR drive?
It uses CMR (conventional magnetic recording), so it offers consistent write performance and full RAID compatibility — unlike SMR drives, which can slow under sustained writes.
What do I need to know before buying?
It is a bare internal 3.5-inch SAS 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, and the SAS SED 0F59373 targets high-availability servers that need dual-port redundancy plus hardware encryption for security and compliance. Choose it when your chassis is SAS-based and you require SED; for SATA servers or non-encrypted needs, a SATA HC590 or WD Gold costs less. Building out 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
Your server or JBOD is SAS-based and needs 24TB per bay
You require hardware TCG SED encryption for compliance
You want dual-port redundancy and a 5-year warranty
Skip it if
Your system only has SATA ports — choose a SATA drive
You do not need self-encryption — a standard drive costs less
You need sub-millisecond latency — choose an enterprise SSD
