A company called DDRdrive LLC has announced the release of a new type of product: the DDRdrive X1. It is a PCI Express card that integrates both 4 GB of DDR and 4 GB of SLC NAND. And what is this hybrid for? To give high level performance for demanding operations in terms of read and write speeds. For now we’re talking server application more than anyting else but you have to say that the DDRdrive X1 is an innovative product. It combines all the advantages of RAM (rapidity, reliability and longevity) with the SSD component to take care of backup when you stop working.
The DDRdrive X1 performance is not very impressive in comparison to recent SSDs because it is limited by the PCIe X1 interface. You therefore get theoretical read speeds of 250 MB/s and 155 MB/s of write. However its in terms of IOPS that the DDRdrive X1 stands out. It manages not less than 300,000 IOPS in random read and 200,000 IOPS in random write (blocks of 512 bytes). A good SSD generally gives a read of 100,000 IOPS. Moreover this level of performance is achieved at just 9.91 watts. The DDRdrive X1 can work in RAID 0.1 and 5.
This product is innovative abut a little bit limited in terms of possible usage as it costs $1495 and has a 4 GB capacity. Its availabilty has not yet been announced by we know already that the DDRdrive X1 will be guaranteed for 5 years.
