Until now, ADATA's SSD portfolio has consisted of client-focused SSDs and industrial-grade models based on similar hardware but optionally rated for extreme temperatures, with only the occasional purely server-oriented SSD. ADATA is entering a new market segment with the release of the SR2000 family of enterprise SSDs with capacities up to 11TB.

The ADATA SR2000 family uses Microsemi's Flashtec NVMe SSD controllers, from the generation codenamed "Belmar" consisting of the NVMe2016 and NVMe2032 controllers with 16 and 32 channels respectively (compared to 4 or 8 for client SSDs). The SR2000 family consists of two product lines: the U.2 SR2000SP and the add-in card SR2000CP. Both product lines include capacities ranging from 2TB to 11TB. The U.2 versions offer hot-swap capability while the add-in card versions support a PCIe 3 x8 interface for much higher sequential transfer rates and slightly better random read speeds. The SR2000 SSDs are aimed at read-intensive workloads, with endurance ratings in the 1-3 drive writes per day range and relatively unimpressive random write speeds.

ADATA hasn't confirmed what flash memory they're using in the SR2000, but is is most likely Micron's 32L 384Gb 3D TLC NAND. This is a generation behind the 64L parts that are currently doing quite well in the client/consumer market. From a hardware perspective, this makes the SR2000 very similar to Micron's own 9200 series enterprise SSDs and some other drives that use the same controller and NAND combination, such as the Memblaze PBlaze5. That isn't to say that the SR2000 will behave the same as other NVMe2016-based drives: Microsemi's controllers dominate the high-end enterprise SSD market but each vendor that adopts the controllers does their own firmware customization. ADATA's product information doesn't offer much information about the firmware, and it is not clear whether advanced NVMe features like dual-port support or multiple namespaces are implemented by the SR2000 SSDs.
