Anobit doubles performance, capacity of SSD using consumer flash

The Genesis 2 series SSD holds up to 800GB

Computerworld - Israeli start-up Anobit today unveiled its second generation of enterprise-class SSDs based on consumer-grade NAND flash chips.

The company has doubled the capacity of its SSD to 800GB, more than doubled performance to 540MBps, halved the size of its NAND flash circuitry, and added a Serial-Attached SCSI (SAS) model to its line-up.

Anobit's new Genesis 2 series SSD is built around an upgrade to the company's controller technology. The series uses the MSP (Memory Signal Processing) 2020 controller, while the Generation 1 used the MSP 1010.

To date, Anobit said it has sold 20 million MSP controllers to systems makers, which include consumer-grade products as well as single-level cell (SLC) SSDs sold by other vendors.

"I think we're differentiated from other vendors in that we've been able to cut our teeth on the controller technology and prove it out in the market place," said Patrick Guay, Anobit's executive vice president of sales and marketing.

The new controller technology gives the Genesis 2 SSD a maximum sequential read/write rate of 540MBps and 510MBps, respectively. The new SSD's predecessor had a sustained sequential read/write rate of 220MBps. and 180MBps., respectively.

The Genesis 2's endurance rate remains the same as its predecessor: 50,000 write-erase cycles, or roughly 10 to 15 times that of typical consumer-based NAND flash. Anobit said it guarantees a write endurance of ten times the drive capacity per day for five years, or 7,300TBs (7.3 petabytes) for a 400GB model drive

As was its first generation product, the Genesis 2 SSDs are targeted at network and server attached storage, as well as enterprise business and cloud-based applications. The SSDs can be used directly in data center application servers to increase performance or as part of a storage subsystem array.

If Anobit's numbers are accurate, the Genesis 2 SSD has staggeringly high performance. The drive generates random read-write rates of 70,000 I/Os and 40,000 I/Os per second, respectively.

Anobit has shrunk its circuitry from the earlier 40+ nanometer (nm) process to 25nm, thereby allowing it to double the capacity of the drive while also shrinking it from a 3.5-in. form factor to 2.5-in. The Genesis 2 ranges in capacity from 100GB to 200GB, 400GB and 800GB.

Anobit's first-generation Genesis SSD comes in 200GB and 400GB capacities with only Serial ATA (SATA) interfaces. The Genesis 1 SSDs require an external bridge to use the serial-attached SCSI (SAS) or the Fibre Channel protocol. The Genesis 2 SSD now comes with native SATA 3.0 in the T-Series or SAS 2.0 in the S-Series.

The T-Series will be available Oct. 7. The S-Series will ship Nov. 30.

As with its first generation Genesis SSD, Anobit's controller technology extended standard MLC endurance from about 3,000 to more than 50,000 write/erase cycles -- making MLC technology suitable for high-duty cycle applications such as relational databases.
