What interface and form factor does this SSD use?

It features PCIe Gen4 x4, NVMe 1.4 interface in U.3 15mm form factor, compatible with U.2 backplanes. This supports standard 2.5-inch infrastructure, delivering up to 6,800 MB/s sequential read and 1,000K random read IOPS for high-performance datacenter use.

What are the reliability specifications?

MTBF is 2.5 million hours projected, uncorrectable bit error rate is 1 in 10^17, and annualized failure rate is 0.35%. These metrics, combined with NVMe-MI 1.1b and secure erase capabilities, ensure high availability in demanding environments like AI/ML and big data.

What NAND technology is used?

BiCS5 3D TLC NAND provides higher bit densities for the 3.84TB capacity. Paired with NVMe 1.4b controller, it enables performance at scale for larger workloads in scale-out solutions and software-defined storage.

What are the power and environmental specs?

Power management requires +12V DC +/-10%, with operating temperature from -40°C to 85°C. This wide range supports rugged datacenter conditions, while features like variable sector sizes enhance compatibility and efficiency.

Is this SSD suitable for cloud datacenters?

Yes, designed for cloud datacenters, big data, NoSQL databases, AI/ML, and archiving. With 1 DWPD, dual-port redundancy potential, and U.3/U.2 support, it optimizes cost for read-intensive, high-capacity needs up to 61.44TB in the series.
