Start-up Claims SSD Achieves 180,000 IOPS

Lucas123 writes "Three-year-old start-up Pliant Technology today announced the general availability of a new class of enterprise SAS solid state disk drives that it claims without using any cache can achieve up to 180,000 IOPS for sustained read/write rates of 500MB/sec and 320MB/sec, respectively. The company also claims an unlimited number of daily writes to its new flash drives, guaranteeing 5 years of service with no slowdown. 'Pliant's SSD controller architecture is not vastly different from those of other high-end SSD manufacturers. It has twelve independent I/O channels to interleaved single level cell (SLC) NAND flash chips from Samsung Corp. The drives are configured as RAID 0 for increased performance.'"

Wonder what controller they used

[afidel]

With all the fast SSD's I've tested I've found the controllers to be a bigger bottleneck than the SSD itself. I've seen 50% performance gains on the Intel x-25e's simply by hooking them to a second machine with a different controller. Even with the best performer (Intel ICH9) I still had the feeling that the controller might have been holding the drive back a bit. Haven't tried it with an ICH10 based board yet though so perhaps there's significant improvements there. (on further reading they claim to be using SAS, I'm not aware of any really high performance SAS chipsets, they all seem to be targeted at RAID's of traditional HDD's and so can't keep up with SSD, I'd really be interested in some details of their test).

Well, I don't know the whole setup, just that it was about 10 drives (15k) SCSI (not SAS) in a RAID 5. I don't know how much cache. It was a Clarion unit. But, the customer thinks, "Wow, your little box that I've never heard of has just beaten EMC." They don't get into the technical details when they make that sort of decision.
