The HPE EF0450FATFE (model number) is a genuine 450GB SAS Enterprise hard drive built for the most demanding enterprise storage environments where performance, uptime, and consistent data access are absolutely critical. Spinning at an industry-leading 15,000 RPM with a 16MB cache buffer and an average seek time of just 3.5ms, it's engineered to deliver maximum IOPS and minimal latency for transaction processing, database workloads, and other mission-critical deployments where every millisecond matters. The 6Gb/s SAS interface provides a stable, high-throughput connection with a data transfer rate of 750 MB/s, which is exactly what ProLiant Gen5 through Gen9 servers and HPE storage arrays are built around.
This drive features dual-port SAS connectivity for built-in redundancy, boosting availability and fault tolerance in enterprise environments. It is also hot-swappable, meaning it can be replaced without shutting down the system — minimizing downtime during maintenance. The drive comes with a standard HPE LFF drive tray / Smart Carrier (SC) pre-attached, making it ready for hot-plug installation in compatible ProLiant systems. Because this is a genuine HPE component rather than a generic or rebadged drive, it's manufactured to the same tolerances and firmware compatibility standards as the original server configuration. That matters when you're replacing a drive in a live server — mismatched or unverified parts can cause RAID rebuild failures or degraded performance.
This HPE EF0450FATFE 450GB SAS hard drive is built specifically for HPE's ProLiant server architecture with Smart Carrier (SC) compatibility, which means it's designed to work within the storage enclosures and backplanes that were engineered to support SAS interfaces. Before ordering, it's worth double-checking your exact server model and backplane revision, since SAS storage systems can vary in supported drive firmware across generations. In general, this drive fits into:
HPE ProLiant Gen5/Gen6/Gen7 Servers:
HPE ProLiant Gen8/Gen9 Servers (LFF Bays):
HPE Storage Systems:
Compatibility Notes:
When you're sourcing a replacement drive for an active server, the difference between a genuine part and an unverified clone shows up the first time you need to rebuild a RAID set. The HPE EF0450FATFE is HPE-manufactured with a genuine HPE security sticker, which means it carries the firmware and mechanical tolerances your server's controller already expects — no compatibility guesswork, no risk of a failed rebuild because of a mismatched drive. Here's what makes this HPE EF0450FATFE 450GB SAS hard drive worth choosing over a cheaper, unverified alternative:
This HPE EF0450FATFE 450GB SAS hard drive fits teams maintaining legacy and current ProLiant server infrastructure who need the absolute highest performance storage without downtime. Common deployment scenarios include:
