Overview

High-Performance Enterprise SSD for Reliable Storage

The Hewlett Packard Enterprise SSD 400GB SAS is a high-capacity solid-state drive designed for enterprise environments. Offering fast data access and reliable performance, this SSD is ideal for demanding storage applications.

Capacity: 400GB
Form Factor: 2.5"
Interface: 12 Gbit/s SAS

Pros & Cons

👍 Pros

12 Gbit/s SAS interface provides high-throughput, full-duplex data transfer suited for enterprise workloads
2.5-inch form factor fits standard enterprise server drive bays without adapters
Solid-state design eliminates mechanical failure points, improving reliability over spinning disks in always-on environments
Enterprise-grade build is designed for sustained read/write cycles typical of data center applications

👎 Cons

400GB capacity is limited compared to modern enterprise SSDs, which may require multiple drives for larger storage needs
SAS interface is not compatible with consumer SATA-only controllers, restricting use to enterprise or server hardware
Drive caddy or tray may not be included, adding cost if a compatible carrier is needed for your server chassis
As an older enterprise part, it may not match the performance or endurance specifications of current-generation NVMe or SAS SSDs

Frequently Asked Questions

What interface does this SSD use and is it compatible with standard servers?

The drive uses a 12 Gbit/s SAS interface in a 2.5-inch form factor, making it compatible with HP ProLiant and other enterprise servers that support SAS drives in their drive bays or caddies.

Is a drive caddy or tray included with this SSD?

Check the specific listing for what is included. Enterprise drives are often sold as bare drives without caddies, so you may need to purchase a compatible HP drive tray separately if your server requires one.

What is the difference between this SAS SSD and a consumer SATA SSD?

SAS (Serial Attached SCSI) supports higher throughput (12 Gbit/s vs 6 Gbit/s for SATA), full-duplex communication, and is designed for the continuous read/write demands of enterprise environments. SAS drives are not compatible with standard SATA-only controllers.

Is 400GB a typical capacity for enterprise SSDs?

Yes, enterprise SSDs are often available in smaller capacities optimized for write endurance and performance rather than raw storage. The 400GB capacity is common for write-intensive workloads where durability and speed matter more than total space.

Can this drive be used in a non-HP server?

The drive itself uses the standard SAS interface, so it can physically work in any server with a compatible SAS controller. However, some HP firmware features or drive monitoring tools may not function in non-HP environments.
