我們現在所知道的SSD都很快!但是還不夠快!
Fusion-io公司能夠提供每秒傳輸1TB的SSD系統!
反應速率可控制低於50 microseconds(答案在下面!小y提供的是錯誤的!!!!!大約是0.005nm?這邊請知道的大德告知小y)
平均有100,000,000的IOPS
而在最糟糕的4kb也會有800,000 IOPS
行走介面是PCI-E 16X GEN2.0版!
OK知道這東西後,再來的SSD都嚇不倒我了!!
感謝lphunter大大提供

microseconds 簡稱「毫秒」( ms)，1秒等於1000ms，所以50ms = 0.05sec
We think that today's top of the line SSDs are very fast relative to what we're accustomed to using from years with magnetic storage. But if for some reason that's still not fast enough for you, there's Fusion-io's SSD technology that's able to reach a blistering 1 TB per second transfer rate.
Such bandwidth was achieved using Fusion-io's development of the ioDrive Octal, which is a PCI-Express card that holds eight ioMemory Modules -- putting the equivalent capacity and performance of eight ioDrives into a single card. By combining the performance of 220 of these ioDrive Octal cards into a six-rack system, the set up is capable of sustaining over 1 TB of aggregate bandwidth with access latencies under 50 microseconds.
To put that into perspective with today's most common storage technology, achieving a 1 TB/sec. sustained bandwidth would otherwise require close to 55,440 disk drives, 396 SAN controllers, 792 I/O servers and 132 racks of equipment.
"We were eager to take on the challenge of creating a device that meets the intense demands of high performance computing. With this architecture, IOPS are easy. We achieved over a hundred million (100,000,000) IOPS, more than enough performance to meet our customer's requirements. The real power in our architecture was the ability to also scale bandwidth," said Steve Wozniak, chief scientist at Fusion-io. "We look forward to productizing the ioDrive Octal in the future, and bringing the power of this solid-state storage technology from the world of HPC to the enterprise."
A single ioDrive Octal, which itself is a considerable speed demon, is capable of 800,000 IOPS (4k packet size), 6 GB/s bandwidth, 5 TB maximum capacity and comes in a x16 gen-2 double-wide PCI Express form factor. |
