Know before you buy
This drive is engineered for cloud data centers and enterprise environments that require high performance and consistent low latency. It is specifically optimized for read-intensive and mixed-use workloads, making it an ideal upgrade for servers currently running on legacy SATA interfaces.
Yes, the SN630 supports hot-swap and hot-plug functionality. This allows you to replace or add drives without powering down the entire server, which is essential for maintaining high availability in data center operations.
The drive includes Instant Secure Erase (ISE) for rapid data sanitization and supports AES-256 encryption. Additionally, it features secure firmware download capabilities to protect against unauthorized firmware modifications.
The SN630 uses a U.2 2.5-inch form factor with a 7mm z-height. While it fits the physical dimensions of a standard 2.5-inch bay, ensure your server backplane supports the NVMe PCIe Gen 3.1 x4 interface required for this drive to function.
This model is rated for an endurance of 0.8 Drive Writes Per Day (DWPD). It is designed for reliability, boasting a Mean Time Between Failures (MTBF) of 2 million hours and an annual failure rate of 0.44%.
The SN630 is designed for energy efficiency, featuring lower power consumption than many comparable PCIe SSDs. It typically operates between 8.75W and 10.75W, with an average idle power draw of 5.80W.
