Packaging / SpecificationsPackaging
The DDRdrive comes extremely well packaged in a case that I’m convinced could withstand a fall from a very tall building, or being run over by a truck, or perhaps even a nuclear holocaust. The case seals so well that it has an air bleeder valve to equalize pressure prior to opening. Included is a driver CD and an AC adapter to supply the X1 with power when the primary system is powered down.
Bomb-proof packaging, anyone? Yes, we got two of them.
The DDRdrive concept is currently focusing on IOPS over throughput. Parallelism is meant to be achieved by using multiple X1’s in a single system. While future products may support PCI-E 2.0 and a greater number of lanes, their first publicly available product will stick with PCI-E 1x.
- The DDRdrive X1’s breakthrough architecture integrates both DRAM and NAND to redefine solid-state storage. Singularly designed to target IOPS intensive applications while setting a new standard in performance, power, and price. The DDRdrive X1 is “The drive for speed.”
The DDRdrive X1’s solid-state storage system features:
- DRAM / NAND Synthesis – A one-to-one correspondence between solid-state storage capacities. Combines the proven speed, reliability, and longevity of DRAM with the non-volatility of NAND. Removes the necessity and performance penalty of a NAND wear leveling implementation. Resolves the intractable random write limitations of a NAND only device with DRAM’s unsurpassed IOPS potential.
- High Performance IOPS Engine – An FPGA based solid-state storage accelerator, in-the-field upgradable and purpose-built to dominate IO operations. Achieves extremely low latency and exceptional IOPS execution.
- Custom Device Driver – Avoids unneeded and archaic protocol translation with a direct-to-hardware storage stack. Bypasses conventional device driver complexity and inefficiency with extensive end-to-end IOPS optimization.
- HBA / Storage Unification – Negates needless data transfers between otherwise physically separate devices, improving data integrity and increasing IOPS performance.

PCI Express Full-Height Half-Length Form Factor
- Primary Storage Capacity: 4GB DRAM
- Secondary Backup Capacity: 4GB SLC NAND
Unavailable Redundant Storage – 134,217,728 bytes
- Complete Drive Backup: DRAM to NAND in 60 Seconds.
- Complete Drive Restore: NAND to DRAM in 60 Seconds.
- Lifetime Number of Drive Backups: 100,000+
- The ‘Redundant Storage’ above is due
to conservative reservation of a portion of flash blocks. Since the
DDRdrive employs high grade SLC flash, and performs only sequential writes to it, the flash will likely outlive it’s
rated 100k write cycles by a fair margin. The reserved flash blocks carry over to the RAM capacity, since the on-board mechanism must be able to perform a 1:1 backup of all available data.
- While the DDRdrive’s RAM clearance prevents it from being installed adjacent to another full height board, we found it can coexist next to a half-height board without interference.
RAM height prevents installation next to other full-height cards, but the heatsink has no trouble clearing half-height boards.
