About The Author David Adams Follow me on Twitter @david_adams 6 Comments 2010-09-29 10:18 pm poundsmack I am interested to see how this works in real world tests when it starts showing up. I’ve always been very happy with SAS and one thing that article fails to mention is what version of SAS their connector is faster than. Though, at 20Gbit/sec per chanel that’s even better than anything in the SAS roadmap: http://www.scsita.org/aboutscsi/sas/SAS_roadmap.html also, how can it be proprietary and be an open standard? “HSDL is an open standard and allows other devices to leverage its high-speed internal connection…” 2010-09-30 1:31 am Kasi How much faster is this than PCIe? I know this can be used for very large amounts of storage but there are already 1TB PCIe SSD drives. It’s seems making a rack with up to 8 of these on each board would be pretty competitive still. 2010-09-30 2:44 am phoenix Uhm, it uses PCIe as the transport. Thus, it can’t be faster than PCIe. 2010-09-30 3:01 am Kasi I didn’t see that in the linked article, must be going blind. Still however, even if it uses PCIe its not a direct PCIe connection so how much extra overhead is this going take compared to just using directly placed PCIe card mounted SSDs? 2010-09-30 3:58 pm rafaelnp this drive interface can be the engineering masterpiece of this century, but the propietary word scares me. no good 2010-09-30 8:17 pm poundsmack Light Peak will be this generations super interface . this one is good too though.
