SSD on PCI-express

I like your Harddrives but why didn’t you develop/produce SSD’s for PCI-Express bus like OCZ’s Revodrive but even better? For example protection plates to save the storage chips from static loads.

The botleneck of fast storage is the interface sata, sas, or even other regular storageinterface. If you could connect storage nearer to the frontsidebus (and PCI-express definitly is) the faster ist the transferrate. To day on sata, you can’t get over 300mb/s but even on PCIe you get over 1gb/s.

Sorry I mean the perfomance max. read/write of the device.

PCI-E 1 lane has 250MB/s, they`ll need  8x slot at least I GUESS.

Yes thats true. The previous version had PCI-E 4x and was a little slower. And its possible to reach a PCI-E 16x (and that could be verry, verry fast)! Is it possible to reach this on the sata-bus? with extreme Raid-0 with a lot of SSD’s? I don’t think so…

The next industry-standard SATA protocol needs to be modified in two ways:

(1)  8G transmission rate using standard SATA / SAS data connectors;

(2)  128b/130b “jumbo frames” during transmission (abbreviated “130/128”).

8G and the 130/128 jumbo frame are both features of the PCI-E 3.0 specification,

so it only makes sense to extend this same logic outwards beyond the chipset,

using standard SATA / SAS transmission cables.

8 GHz / 8 bits per byte = 1 GB per second PER PCI-E LANE!!

Thus …

  x4 Gen3 @ 1GBps =  ~4GBps

  x8 Gen3 @ 1GBps =  ~8GBps

x16 Gen3 @ 1GBps = ~16GBps in each direction!

Storage devices can be rendered compatible with jumpers,

and/or auto-detection.

Here’s a somewhat theoretical article I wrote on this subject:

Hope this helps.
