HPE 804677-K21 1.2TB 2.5inch Small Form Factor (SFF) Power Loss Protection (PLP) Digitally Signed Firmware (DS) SAS-6Gbps Smart Carrier Write Intensive Solid State Drive for ProLiant Gen8 Gen9 Gen10 Servers (Brand New with 3 Years Warranty)

HPE Solid State Drives (SSDs) deliver exceptional performance and endurance while reducing power consumption for customers with applications requiring high random read and write IOPs performance. These drives deliver higher performance, better latency, and more power-efficient solutions when compared with traditional rotating media.

HPE Server Write Intensive (WI) Solid State Drives (SSDs) deliver high performance and endurance for customers with applications requiring a balance of write IOPS performance. HPE (WI) SSDs typically have an endurance of >=10 drive writes per day (DWPD). All HPE SSDs are backed by over 3.35 million hours of testing and qualification ensuring reliable, high-performing drives. The self-describing icons on the HPE Smart Carrier take the guesswork out of a drive’s status, and a “do not remove” button prevents data loss from human error. You can also monitor the lifespan of your SSD with HPE SmartSSD Wear Gauge compatibility in management tools, allowing you to determine if any drives are at risk of failure.

HPE SSDs offer High Performance, Exceptional Reliability, and Efficiency for Faster Business Results
Ideal for big data analytics, cloud computing, active archiving, database applications, and data warehousing.
Achieve higher IOPS to enhance the performance of your data center.
Maintain data accuracy with full data-path error detection.
Choose from a broad portfolio of enhanced solutions in capacities up to 15.3 TB and growing.
12 Gb/s SAS, 6 Gb/s SATA, and NVMe.

Smart Carriers
HPE Hard Drives with smart carriers are designed to provide an interface to communicate critical status and management information. System status LED icons and a spinning activity ring reflecting the data-writing process notify users of the current system status. A blue LED located behind the handle can be activated remotely to guide users to a specific drive tray, while a do-not-remove icon positioned on the tray's eject button lights up to warn users when the removal of the drive would cause data loss.

Digitally Signed Firmware: Prevent unauthorized access to your data with the expansion of integrated HPE Digitally Signed Firmware (DS) on new drives; providing the security and assurance that drive firmware comes from a trusted source and protects against malicious attacks.

The HPE 804677-K21 Write Intensive Solid State Drive has a 2.5 inch form factor and a 6 Gbps data transfer rate. It has a 1.2 TB capacity. This Small Form Factor Solid State Drive with Digitally Signed Firmware uses a SATA-6Gbps interface and comes with 3 Years Warranty.
