Seagate Exos X24 ST24000NM005H — 24TB SED SAS HDD
24 TBSAS 12 Gb/sSEDCMR · 512 MB
The Seagate Exos X24 ST24000NM005H is a 24 TB enterprise-class 3.5-inch hard drive with a native SAS 12 Gb/s interface and hardware Self-Encrypting Drive (SED) security, built for hyperscale and enterprise data centres. Its helium-sealed CMR platform spins at 7200 RPM with a 512 MB cache and delivers up to 285 MB/s sustained. Identified by part number ST24000NM005H (EAN 8719706431149), it is rated for 550 TB/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 12 Gb/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). As a Self-Encrypting Drive, hardware AES encryption is always active; to manage keys and Instant Secure Erase you need a host or controller with TCG/SED 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 12 Gb/s dual-port
A SAS-3 12 Gb/s interface with dual-port capability provides redundant data paths and high throughput for enterprise servers and high-availability JBOD arrays.
Self-Encrypting Drive (SED)
Hardware AES self-encryption with Instant Secure Erase delivers compliant data protection and lets you cryptographically wipe the drive in seconds at end of life.
Helium CMR reliability
A helium-sealed CMR (conventional magnetic recording) platform sustains consistent write performance and RAID compatibility with no SMR shingled-write penalty.
Enterprise endurance
Rated for 550 TB/year workloads, a 2.5-million-hour MTBF and a 0.35% annualised failure rate, backed by a 5-year limited warranty.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The Exos X24 is Seagate’s flagship enterprise drive, and the SAS SED ST24000NM005H targets high-availability servers that need dual-port redundancy plus hardware encryption — a step beyond single-port SATA drives like the WD Gold or Exos X24 SATA. Choose it when your chassis is SAS-based and compliance requires SED; for SATA servers or NAS, a SATA Exos or WD Gold costs less. Building out an 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 24 TB per bay
You require hardware 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
