The HPE 804677-B21 is a high-performance solid-state drive designed for use in servers. It is a 2.5-inch small form factor (SFF) device with a storage capacity of 1.2 terabytes (TB). The drive is based on Serial Advanced Technology Attachment (SATA) technology and offers a data transfer rate of 6 Gigabits per second (GBPS). It is equipped with a smart carrier (SC) that allows for hot plug capability. In this article, we will explore the features of the HPE 804677-B21 in detail.
Serial Advanced Technology Attachment (SATA)
The HPE 804677-B21 is a SATA-based solid-state drive. SATA is a widely used interface for connecting storage devices such as hard disk drives (HDDs) and solid-state drives (SSDs) to a computer's motherboard. SATA was introduced as a replacement for the older Parallel ATA (PATA) interface, which had been in use since the 1980s.
SATA offers several advantages over PATA, including faster data transfer rates, better scalability, and improved error correction. SATA also uses a thinner cable than PATA, which makes it easier to route within a computer case.
6 Gigabits Per Second (GBPS) Data Transfer Rate
The HPE 804677-B21 offers a data transfer rate of 6 Gigabits per second (GBPS). This is the maximum theoretical speed of the SATA III interface, which is the latest version of the SATA standard. The SATA III interface is backward compatible with earlier versions of SATA, so the HPE 804677-B21 can be used with older SATA II or SATA I interfaces. However, the data transfer rate will be limited by the slower interface.
A data transfer rate of 6 GBPS is much faster than the maximum transfer rate of a traditional hard disk drive (HDD), which is typically around 150 Megabytes per second (MBPS). This makes the HPE 804677-B21 an excellent choice for applications that require fast data access and retrieval, such as online transaction processing, data warehousing, and multimedia streaming.
1.2 Terabytes (TB) Storage Capacity
The HPE 804677-B21 has a storage capacity of 1.2 terabytes (TB). This is equivalent to 1,200 Gigabytes (GB) or 1,200,000 Megabytes (MB). The high storage capacity of the drive makes it ideal for storing large amounts of data, such as databases, media files, and virtual machines.
2.5-inch Small Form Factor (SFF)
The HPE 804677-B21 is a 2.5-inch small form factor (SFF) solid-state drive. SFF drives are smaller and lighter than traditional 3.5-inch drives, making them ideal for use in space-constrained environments, such as blade servers, small form factor desktops, and laptops.
Smart Carrier (SC) with Hot Plug Capability
The HPE 804677-B21 is equipped with a smart carrier (SC) that allows for hot plug capability. Hot plug capability means that the drive can be inserted or removed from a server without the need to power it down first. This feature makes it easy to add or replace drives in a server without interrupting the operation of other drives.
The smart carrier (SC) also provides additional information about the drive, such as its serial number, capacity, and firmware version. This information can be useful for system administrators who need to keep track of multiple drives.

Compatibility for Write Intensive SSD
- To ensure compatibility for a write-intensive SSD with the HPE servers listed, it is recommended to check the server's technical specifications and storage requirements for compatible SSDs. HPE provides a compatibility matrix for their servers which lists compatible storage devices.It is also important to check the SSD's interface (SAS, SATA, PCIe NVMe) and form factor (2.5 inch or 3.5 inch) to ensure it matches the server's requirements.In addition, it is recommended to consider the workload requirements and endurance rating of the SSD to ensure it can handle the write-intensive workload. Endurance rating indicates the number of program/erase cycles an SSD can handle before its performance and reliability are affected. It is recommended to choose an SSD with a higher endurance rating for write-intensive workloads.
