Default More details on DDRdrive X1: $1495 for 4Gb Version

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.

looking at the Write IOPS the DDRdrive X1 is amazingly fast, faster than a system DDR drive? how is that possible

I-RAM... nice

8 Raptors in RAID 0


X25-M SSD


14gb RAMDISK

The secret sauce to any RAM drive... build a drive controller that can at least pretend to keep up with the RAM. Looks like they attempted exactly that but focusing purely on IOPs...

the last result posted above is from a 14Gb ram drive (DDR3) ; it's only 12x faster than X25-M in write IOPs, the DDRdrive X1 is twice as fast as that; how can this be?

The DDRdrive's controller is hooked up to RAM, so the only limitation would be the drive controller... They obviously engineered a controller designed to better handle the speed of RAM modules, at least in IOPS.

Remember how SSD's work... X25-M uses 10 controller channels. In order to beat a system RAMdisk the DDRdrive could use mutliple channels as well, one controller per channel in "RAID-like" fashion with one or two memory DIMM's per channel. Or perhaps a single very complex controller with multiple memory controllers to simulate multiple channels. Would have to be something along this fashion.
