REPORT ANALYSIS AND CONCLUSION
We have to admit, these are the types of reviews we love doing. This entire process just screamed “MORE”. More drives, more RAID adapters, more speed, more of everything. Luckily for us, the Adaptec ASR-72405 and the SMART Optimus SSDs came through with outstanding performance.
With the SMART Optimus, we knew what were getting into. It was like rediscovering an old friend (if old friends are enterprise SSDs). We loved the drive when we reviewed it in 2012 and nothing over the past few weeks did anything to change that opinion. The level of consistency these drives offer is outstanding.
The Adaptec ASR-72405 was a completely different story. The previous Series 6 adapters were showing their age, especially when compared to the competition. But, with Series 7, Adaptec made some very bold claims and even bolder moves. We commend Adaptec for bucking the 8-port ROC trend and unleashing the 24-port PM8015 ROC. By enabling 24 native ports, Adaptec is able to bypass the expanders required for traditional, large drive count systems. Adaptec was also first to market with the use of min-SAS HD connectors and cabling. This allows Adaptec to double the port count in LP MD2 PCIe slots that are so prevalent in the server market.
Every time you look at the ASR-72405, you are reminded of the ground-up effort that was put into this product after the Adaptec/PMC-Sierra acquisition. It seems very purpose built, with a clear product positioning strategy. This is clearly a shot across the bow of LSI. If you weren’t convinced of that, take a look at all of their product comparisons. You may notice some familiar results under “Competing 8-port adapter”. You might also notice the word “Bottleneck” slapped on top of a familiar RAID adapter outline. All of this would be for not if Adaptec’s Series 7 could not live up to expectations.
We spent quite a bit of time putting this setup through the wringer and we can say that the ASR-72405 definitely lived up to expectations. With 6600MB/s at its disposal, it comes close to saturating the x8 PCIe GEN3 link. The ASR-72405 does a great job of juggling read and write operations. Unless you need the extra 8 ports for capacity, the 16-port ASR-71605 appears to be the performance sweet spot. Enterprise customers should flock to this card as it greatly simplifies their setups.
In the end, the quest for 1M 4KiB IOPS was actually more of a stroll. Who would have thought hitting 1M IOPS would be so easy? Editor’s Choice!
