Toshiba America Electronics Components, Inc.’s Storage Products Business Unit is announcing a new series of enterprise SSDs (eSSD). The HK3E2 and HK3R2 both feature Toshiba’s second generation A19(nm) MLC NAND flash memory coupled with a Toshiba-designed enterprise controller. The HK3E2 series is geared toward value endurance workloads, while the HK3R2 series is geared toward read-intensive workloads.
Ideally suited for enterprise environments, both the HK3E2 and the HK3R2 utilize the SATA 3.2 (6.0GB/s) interface, and enterprise-level endurance features such as power-loss protection and end-to-end data protection. Both drives also incorporate Toshiba’s proprietary QSBC (Quadruple Swing-By Code) error correction technology. QSBC is a highly efficient error correction code (ECC) that helps prevent corrupted data caused by NAND wear, improving reliability and extending the lifespan of the drive.
According to Cameron Brett, director of SSD product marketing at Toshiba Storage Products Business Unit, “The HK3E2 and HK3R2 Series address different application requirements but offer the same platform commonality to help customers leverage testing and minimize redundant qualification activity. With a Toshiba-designed enterprise SATA SSD controller and integrated Toshiba 19nm second generation NAND flash memory, customers are offered the performance and data integrity they need.”
The Value Endurance HK3E2 series is being offered in capacities of 200GB, 400GB and 800GB. Sequential read speeds are stated as 500MB/s for all capacity points. Sequential write speeds vary by capacity, with the 200GB attaining 270MB/s and the 400GB and 800GB versions attaining 400MB/s. Random 4K reads speeds are stated as 75,000 IOPS for all capacities. Random 4K write speeds vary by capacity, with the 200GB at 20,000 IOPS and the 400GB and 800GB versions at 30,000 IOPS. Endurance is stated as three drive writes per day (DWPD) for five years under random 4K workloads.
The Read Intensive HK3R2 series is being offered in capacities of 120GB, 240GB, 480GB and 960GB. Sequential read speeds for all capacities is stated as 500MB/s. Sequential write speeds vary by capacity, with the 120GB at 120MB/s, the 240GB at 270MB/s, and both the 480GB and 960GB at 400MB/s. Random 4K read speeds for all capacities is stated as 75,000 IOPS. Random 4K write speeds vary by capacity, with the 120GB at 4,000 IOPS, the 240GB at 10,000 IOPS, the 480GB at 12,000 IOPS and the 960GB at 14,000 IOPS. Endurance is stated as one drive write per day (DWPD) under random 4K workloads.

These new enterprise SSDs further add to Toshiba’s wide portfolio of enterprise storage offerings, featuring various endurance ratings for specific applications and customer usage scenarios. You can view the Toshiba press release announcing the HK3E2 and HK3R2 series in its entirety here.
Is it possible tha these controllers are based on OCZ IP ?
i mean, it would make sense, since they bought them and OCZ has lots of expertise in controller tech.
Or possibly Phison, as there is a relationship there also, and Phison has announced plans to move more strongly into enterprise controllers.
Yeah, but they dont own Phison though, so it makes little sense to license controller IP if you have one inhouse.
But does Toshiba’s inhouse have an enterprise version? Until they develop their own, they may have to go outside so as to get a foothold in an exploding market now. Keep in mind that the press release says “Toshiba-designed”, not “Toshiba-produced” or “Toshiba-designed and -produced.”
OCZ has bunch of enterprise grade stuff and plenty of expertise in that field, so its only reasonable to get that from them (since they own them).
