Start-up Claims SSD Achieves 180,000 IOPS 133
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.'"

Claims? As in no one else but the company has stated this "fact"? I wish this article waited for a review before being posted :S

TFA said serial-attached SCSI (SAS) was currently 6Gb/sec going on to 12 by 2012. SATA III is also 6Gbit/sec.
0.5GB/sec is 4Gbit/sec, which is under the SAS limit.
Even if it were SATA @ 3Gbit/sec that would still be quite fast.

That doesn't get around the bottleneck at all. You've got the same ratio of actual bandwidth used to theoretical bandwidth possible.
A single drive with multiple SATA interfaces, acting like RAID 0, would alleviate the bottleneck.

I get nearly 2X the speed of a single drive that is limited by SATA. Theoretically, that might not be the same thing but for all *PRACTICAL* purposes, it gets around the bottleneck just fine for me :-)

Emphasis on "in theroy" as I had an SSD go with absolutely no warning less than 48 hours after installation, but I'm filing that under bad luck.
I'd call that good luck. Bad luck would be 48 days.

Yep, doubling your bus count usually doubles your transfer speed. *rolling eyes*
