ST1800MM0129 – 1.8TB Enterprise Hard Drive
The Seagate ST1800MM0129 is a 2.5-inch enterprise-class hard drive built for data center workloads that demand fast random access in dense storage configurations. With a 10,000 RPM spindle and SAS 12 Gb/s interface, it suits virtualization, transactional databases, and high-IOPS tiered storage where capacity per watt matters. As a spindle-based drive, it complements rather than replaces SSDs — pair it with flash tiers for hot data and use it for cost-efficient mid-tier performance storage.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model | ST1800MM0129 |
| Brand | Seagate |
| Capacity | 1.8TB (1800GB) |
| Form Factor | 2.5-inch (ideal for high-density chassis) |
| Interface | SAS 12 Gb/s (Serial Attached SCSI) |
| Spindle Speed | 10,000 RPM (higher random I/O than 7,200 RPM class) |
| Cache | 128MB |
| Data Transfer Rate | Up to 210 MB/s (sequential, outer tracks) |
| Designed for | Enterprise and data center environments |
Good to know
- Requires a SAS-compatible controller or HBA — the SAS 12 Gb/s interface will not connect to standard SATA ports, so confirm backplane and controller support before ordering.
- Within Seagate’s enterprise portfolio, this 2.5-inch 10K class drive fills the performance tier between capacity-oriented 3.5-inch 7,200 RPM drives (such as the Exos series) and SSDs, trading capacity per unit for faster access times.
- For high-density enclosures, the 2.5-inch form factor allows more drives per chassis — verify your server’s drive bay count and power/cooling headroom to size the array correctly.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
