I Feel the Need for (Read) Speed

Author: Neil Cameron

Our Adaptec team in Germany has put together a vendor lab where vendors, such as hard drive and SSD manufacturers, speedometercan bring their gear and test against our products. While we have validation testing going on all the time in other PMC centers, having the ability for a vendor to sit and play with the combination of our gear and theirs is getting people pretty excited.

Our German engineering team are constantly putting new SSDs (for example) through their paces and providing feedback to the vendors – a collaborative effort to make sure that business, enterprise and data center customers get the product combinations that work for them.

So PMC is putting in some big efforts to make sure that we are at the cutting edge of SSD design performance to keep up with some of these amazing devices being developed.

I was chatting to my PMC mate in Germany late last month, and while discussing all things technical, he mentioned to me the new Toshiba PX03SN range of SSDs that he’s been testing. Are they fast I ask? 1100MB/sec read speed was the answer.

STOP. Have I fallen asleep during this phone call and am now dreaming of SSDs or did I hear that correctly?

Yes, I heard it correctly. 1100MB/sec read speed. OK, the write speed is only 380MB/sec, but who cares? With 100,000 4K IOPS read speed and 26K IOPS write speed, these things are amazing. Of course you need an Adaptec Series 8 12Gb/s controller to make these work, and yes six of them will saturate the controller, but it’s not actually the controller that saturates, it’s the PCIe bus.

Imagine that, PCIe 3.0 is not fast enough already. No idea when we’ll see 4.0, but 3.0 (8 lanes) has a maximum throughput of around 6,600MB/sec, which we used to need 16 drives to easily hit. My German mate is telling me he can do this straight out of the box with six drives now.

I wonder how fast one of these things will boot Windows? 🙂
