ADATA showed off a new high-performance server-grade SSD, the SX2000. Built in the 2.5-inch form-factor, this drive features a PCI-Express 2.0 x4 interface (a cable runs to a PCIe riser card). It is driven by an LSI-SandForce SF-8639 controller, which is a single-chip solution that connects to the host over PCI-Express, and appears to the operating system as ATA AHCI controller, with one drive connected to it. The chip features nearly more than double the ONFI channels as an SF-2281, which reflects on the drive's advertise performance numbers: up to 1,800 MB/s reads with up to 1,800 MB/s writes; up to 200,000 IOPS 4K random reads. The controller supports all modern enterprise SSD features, including TRIM, DEVSLP support, and SMART. It ships in 100 GB, 200 GB, 400 GB, 800 GB, and 1,600 GB variants. The latter was up on display.

ADATA also showed off its SX1000 enterprise SSD, which features a more modest SATA 6 Gb/s interface, an LSI SandForce SF-2500 or SF-2600 series controller, sequential performance numbers of up to 550 MB/s reads with up to 500 MB/s writes, up to 75,000 IOPS 4K random reads/writes, can work as DAS, and most modern enterprise features. This drive will be available in 100 GB, 200 GB, and 400 GB capacities, the 200 GB variant was on display. It's unclear which kind of NAND flash the two drives use, but we're guessing it's high-endurance MLC NAND. Both offer 5-year warranties.
