First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
OCZ releases new customizable enterprise-class SSD
- — 21 June, 2011 14:10
OCZ Technology today released a new enterprise-class solid-state drive (SSD), the Deneva 2, which comes with SandForce's latest controller technology, almost doubling the performance over its last iteration of the drive.
Like the original Deneva SSD, the Deneva 2 is a customizable product, coming in two series with multiple form factors, interfaces and NAND flash memory types, from high-end single-level cell (SLC) flash, and enterprise-class multi-level cell (MLC) flash to consumer-grade MLC.
The Deneva comes in the "R" or Reliability series and the "C" or Commercial series. The R series comes with SandForce's 2582 controller, and sports a 10 million hours meantime between failure (MTBF) rating. The C series comes with a SandForce 2281 series controller and has an MTBF of 2 million hours.

The SSD can also be purchased with SATA 3.0, SAS 2.0 or PCIe interfaces, and it can come in 1.8-in, 2.5-in and 3.5-in form factors as well as customizable casings, according to Alex Mei, OCZ's chief marketing officer.
The Deneva 2 comes in capacities ranging from 64GB to 512GB and has a read speed of up to 550MB/sec, a write speed of up to 525MB/sec and, using 4K random writes, can generate up to 80,000 I/Os of throughput per second (IOPS).
The first version of the Deneva came with a SandForce 1500 controller , which offers I/O performance of up to 285MB/sec for reads, 275MB/sec for writes, and 4KB random writes up to 50,000 IOPS.
Like the original Deneva SSD, the new product is targeted at the highest-end customer: the makers of enterprise-class storage systems, Mei said.
"You can't even find Deneva products on our commercial site. They are customizable for equipment manufacturers in the enterprise space," Mei said. "These probably won't find their ways into end user's computers."
The Deneva 2 also comes with version 2.0 of OCZ's Virtualized Controller Architecture firmware, which balances I/O across the drive's multiple controller chips for better performance. The drive also supports ATA-TRIM command, which allows the operating system to erase data marked for deletion and consolidate existing data so it can be read sequentially instead of randomly.
Additionally, the Deneva supports AES 128- and 256-bit encryption.
