Seagate Enterprise Hard Drives — Exos & Savvio Series
SAS and SATA enterprise HDDs for servers, SANs, and storage arrays
About Enterprise Hard Drives
Seagate's enterprise hard drive lineup is the backbone of data centers worldwide. The Exos series delivers industry-leading capacity per drive (up to 24 TB), while performance-tier SAS drives handle transactional workloads that demand high IOPS.
We maintain deep inventory across the full Seagate enterprise range — from 600 GB 15K SAS drives for legacy arrays to 20+ TB Exos nearline drives for capacity-optimized storage tiers.
Seagate Enterprise Drive Families
- Exos X (X20, X18, X16) — Nearline SAS/SATA, 7.2K RPM, 12-24 TB. Optimized for sequential throughput and capacity density. Ideal for backup, archive, and file storage.
- Exos 10E2800 — Enterprise performance SAS, 10K RPM, 600 GB-2.4 TB. The go-to for transactional workloads and mixed I/O patterns.
- Exos 15E900 — Maximum performance SAS, 15K RPM, 300-900 GB. Highest HDD IOPS for legacy applications that haven't migrated to SSD.

Frequently Asked Questions
What is the difference between Seagate Exos and Barracuda?
Exos drives are enterprise-grade: 24/7 duty cycle rated, 2M+ hour MTBF, vibration-tolerant for multi-drive arrays, and available in SAS interface. Barracuda is consumer-grade: designed for desktop use, lower MTBF, no SAS option, and not rated for RAID or 24/7 operation. Never use Barracuda drives in a server — use Exos.
How long do Seagate enterprise drives last?
Seagate Exos drives carry a 5-year warranty and are rated for 2.5 million hours MTBF. In practice, enterprise drives deployed in properly cooled environments with vibration isolation commonly operate for 6-8 years. We recommend proactive replacement at 5 years for mission-critical systems as a risk management practice.
SAS vs SATA — which Seagate Exos should I buy?
Choose SAS (12 Gbps) if your server/array has a SAS backplane and you need dual-port redundancy. Choose SATA (6 Gbps) for servers with SATA-only connections or when cost per TB is the priority. Performance is similar for sequential workloads; SAS wins for random I/O and multi-path environments.
Can I use Seagate Exos drives in HP or Dell servers?
Absolutely. Seagate Exos drives are standard SAS/SATA devices compatible with any server. Ensure you have the correct drive caddy for your server model (HP, Dell, Lenovo, etc.). We include the matching caddy upon request — just specify your server model when ordering.
