Know before you buy
No, this drive uses a SAS 12Gb/s interface, which requires a dedicated SAS controller or a server-grade motherboard. It is not compatible with standard SATA ports found on typical consumer desktop PCs.
Conventional Magnetic Recording (CMR) provides more consistent write performance and better reliability for data-intensive workloads compared to SMR drives. This makes it the preferred choice for enterprise environments where data integrity and sustained speeds are critical.
HelioSeal technology replaces the air inside the drive with helium, which reduces internal friction and turbulence. This allows for a higher-density 11-disk design, resulting in lower power consumption and cooler operating temperatures.
The Mean Time Between Failures (MTBF) rating of 2.5 million hours indicates the drive's high level of reliability for 24/7 continuous operation. It is a statistical measure suggesting the drive is engineered to withstand the heavy, constant read/write demands of a data center.
No, this is sold as a bare drive. You will need to provide your own mounting screws, drive trays, and SAS cables to install it into your server or storage enclosure.
OptiNAND integrates an iNAND embedded flash drive with the traditional magnetic media to improve drive capacity and performance. It helps manage metadata more efficiently, which enhances overall system responsiveness and data protection.
