As cloud and scale-out data centers have become more and more disaggregated, storage has been able to scale independently from compute, giving businesses elasticity during peak demands while avoiding data silos and improving TCO.

Disaggregating storage is ideal for cloud service providers. It offers a variety of storage services that combine to deliver a higher quality-of-service, improved performance consistency, and higher storage utilization.

For scale-out data center customers, disaggregated storage provides managed service providers to efficiently increase capacity for modern applications processing large unstructured datasets.

As workloads grow to petabytes, high capacity, cost-optimized storage SSDs have an increasingly important role to play. The Ultrastar DC SN650 NVMe SSD can reduce those time-to-insights.

The Ultrastar DC SN650 NVMe SSD includes the next generation Western Digital controller, PCIe Gen 4.0 interface, and Western Digital BiCS5 TLC 3D NAND.

BiCS5 TLC 3D NAND, with higher bit density per mm², is the next generation of 3D NAND driving higher capacities, up to 15.36TB. With PCIe Gen 4.0, the Ultrastar DC SN650 enables performance at scale for increasingly larger application workloads. Designed and built for the standard 2.5" SSD storage infrastructure, it includes support for U.2 and U.3 backplanes.

The Ultrastar DC SN650 NVMe SSD is optimized for cloud and scale-out workloads requiring higher QoS consistency, and better storage utilization for block, object, or file storage.

Emerging workloads for big data, artificial intelligence, and machine learning are increasing in size and complexity. They are typically stored across distributed, tiered, or disaggregated architectures. The Ultrastar DC SN650 NVMe SSD is optimized for moving these large datasets fast and servicing multiple hosts with performance consistency, making them ideal for scaling capacity and maximizing GB per watt for these emerging larger workloads.

The Ultrastar DC SN650 NVMe SSD ensures that if you lose power, you don't lose your data. The drive comes with Power Loss Protection that keeps your data safe should you experience a sudden and unexpected interruption in power supply. And if you ever need to decommission the drive, Secure Erase provides you with entire drive erase options.

The Ultrastar DC SN650 NVMe SSD is built for reliability, incorporating enterprise-class features such as power-loss protection, 2M hour reliability (projected) and 1 DW/D. And if that weren't enough, it also comes with a limited five-year warranty.

Q: 4. In an external enclosure, will this work with mac, and does it run hot?

A: Yes, the WD 4TB WD_BLACK SN850X Gaming Internal NVMe PCIe 4.0 SSD can be used in an external enclosure with a Mac as long as the enclosure is compatible with MacOS. The SSD does not run too hot to use in an enclosure with passive cooling.

Q: 5. Will this work in MSI Creator Z16 as boot or secondary drive. I presume the heatsink wouldn't fit. Thanks

A: The BH #SEZP2GM3A013 with out heat sink would work. Heatsinks will not fit.

Q: 6. Will the WD Black SN850X WITH THE HEATSINK fit in the OWC Express 4M2 4-Slot M.2 NVMe SSD Enclosure?

A: No, the OWC Express 4M2 has a built-in fan to cool the SSDs. The fan does not have the clearance to use the heatsink on the WD 2TB WD_BLACK SN850X Gaming Internal NVMe PCIe 4.0 SSD with Heatsink.

Q: 7. I am wanting to purchase this Seagate FireCuda M.2 but was wondering if it will work in the OWC Ministack STX enclosure? I am wanting to hook it up to my new Mac Studio thru Thunderbolt 4 if that is possible? Please help. Thank you.

A: Yes, the Seagate 4TB FireCuda 530 M.2 SSD without Heatsink BH #SEZP4GM3A013 is compatible with the OWC miniStack STX External Drive Enclosure with Thunderbolt Hub Xpansion BH #OWCT4MS6000.
