Three PX-Series SSDs from Toshiba Celebrate 25th NAND Anniversary

The NAND Flash storage industry is turning 25 this year so, naturally, Toshiba is celebrating it by releasing a new product line, or perhaps we should say three device series.

We said in the title that Toshiba had completed three new solid state drives, but the truth is that each “drive” is actually a 2.5-inch storage series on its own, with 3 or four capacity options.

One of the trio is called PX02SM, relies on the SAS 6.0 Gbps interface and has a thickness of 7 or 15 mm (0.27 – 0.59 inches). It is built out of 24nm eMLC (enterprise multi-level cell) NAND Flash chips (64 Gb/die).

The second SSD, PX02AM by name, uses the same chips but only comes in 7 mm / 0.27 inch thickness and relies on the SATA 6.0 Gbps interface (SATA III). The capacities are 100 GB, 200 GB and 400 GB.

Third and last, but not least, is PX03AN, with 55 GB, 120 GB, 240 GB and 480 GB storage options. It boasts the SATA 6.0 Gbps technology and, rather than 24nm eMLC, 19nm cMLC (consumer multi-level cell) chips.

“As SSDs continue to broaden their reach into enterprise applications, from web servers to data centers, our customers are looking for a broad set of SSD solutions,” said Joel Hagberg, vice president of marketing at Toshiba’s Storage Products Business Unit.

“Today’s announcement further demonstrates how Toshiba is providing our partners with the ability to deliver the best storage solutions for every enterprise need.”

The Toshiba PX02SM, as the first of the company's solid state drives to use 24nm eMLC technology, is aimed at high-performance applications, where its two SATA 6.0 Gbps ports will be useful. Indeed, they are dual-port SSDs so that the top transfer speed may be of 12 Gbps, sequential performance touches 900/400 MB/s read/write while random read/write is 120,000 / 30,000 IOPS.

PX02AM is the so-called “value” line, for mid-range servers and the like, where capacity/performance balance is suitable. It works at up to 500/240 MB/s read/write and 36,000 / 5,000 IOPS.

As for PX03AN, it is good for entry-level servers and anything with a need for quick data access and reading, like system boot up. Read/write performance matches that of the PX02AM, though random read/write is of 30,000/1,500 IOPS tops.

Shipments of the newcomers will begin in the fourth quarter of the year, for as yet unspecified prices.
