Toshiba Debuts Read Optimized, 19nm Enterprise SSDs

By Pedro Hernandez

Toshiba is looking to give enterprise storage workloads a cost-effective boost with its new read-optimized solid-state drives.

Toshiba has expanded its enterprise SSDs portfolio with the new PX03SN series. Aimed at "read-intensive" workloads, the 2.5-inch drives sport a SAS 3.0 interface (12.0 Gbps) and capacities ranging from 200 GB to 1.6 TB.

Suitable for "online transactions, cloud computing, online gaming and big data analytics," according to Toshiba, PX03SN SSDs are a low-cost means of enjoying the fast data transfer rates of flash-based storage without paying a premium.

PX03SN SSDs are based on 19nm MLC NAND flash chips. Supporting one complete drive write per day (DWPD) for at least five years, they are positioned as a budget-friendly alternative to the company's eMLC-based hardware, including its enterprise endurance SSD line, the X02SS series, which can tolerate up to 30 DWPDs, and its mainstream enterprise offering, the PX02SM series with 10 DWPD.

Keeping to the product's purpose, input-output operations per second (IOPS) are heavily skewed toward the read side of the performance spectrum. PX03SN flash drives deliver 130,000 sustained IOPS in 4k random read speeds and 26,000 IOPS in 4k random reads.

Mean time between failure is rated at 2 million hours. The 'Q' and 'U' (PX03SNQ) versions of the SSD includes additional security features, namely built-in encryption and an instant-erase, drive sanitization option. All models feature power loss protection safeguards that retain data in the event of an outage. PX03SN SSDs are scheduled to start shipping this month.

Toshiba's enterprise SSD portfolio may soon grow much bigger.

The electronics maker has offered to acquire OCZ, a San Jose, Calif.-based provider of SSDs and PCIe flash add-on cards, as part of the latter's bankruptcy proceedings. In a statement, OCZ revealed that it had "received an offer from Toshiba Corporation to acquire substantially all of the Company's assets in a bankruptcy proceeding."

The deal, expected to close if given the go-ahead by bankruptcy courts, also hinges on "the preservation of the value of the business, including the retention of employees," stated OCZ.

Toshiba, courtesy of its investments in Violin Memory, is also eyeing the burgeoning PCIe SSD and all-flash array markets. In March, the companies entered into an IP-sharing agreement that, according to Violin Memory CEO Don Basile, will enable the companies to "drive radical new economics that lead to the mass adoption of memory-based architectures."
