Adaptec (by PMC) ASR-8885 12Gb/s PCIe RAID Adapter Review – Raid Testing With 8 HGST 12Gbps SSDs

REPORT ANALYSIS AND CONCLUSION

ASR-8885-1

Before we get to our final thoughts, we want to spend a minute thanking HGST for providing us with eight SSD800MM SSDs.  There is no way we could have achieved the results that we did without HGST’s support.  As we found out in our LSI 12Gbps review, the SSD800MM is a great drive with amazing, consistent performance.

ASR-8885-Top

With that said, we also have to take our hats off to Adaptec.  Their ASR-8885 is a great RAID adapter.  It offers 16 ports of 12Gbps SAS with amazing throughput.  We had no issues hitting 700K IOPS and 6GB/s.  Those are amazing maximums, but we were more impressed with the incredible consistency that we observed.  With sub-microsecond variance, the Series 8 destroyed our latency tests.

Although prices may be high for the consumer market, the pricing for enterprise customers is very competitive, especially on a per port basis.

We applaud Adaptec for not resting on the success of the Series 7.  It would have been easy for them to let LSI take the lead in the 12Gbps market, especially since 12Gbps SAS is in its infancy and there are only a handful SSD that can saturate 6Gbps SAS.  Nobody would have blamed them for taking more time to get this product out.  But, this is the exact reason why the PMC-Sierra acquisition was so important.  It allowed Adaptec to lead in the market and not just follow.

Without a full LSI 12Gbps RAID adapter to compare it to, we can’t quite call Adaptec the winner for this round.  But, with the reemergence of Adaptec, it doesn’t matter, the real winner is the consumer.

Wow.

I didn’t see the ASR-8885 as being listed, via the Amazon link provided. Is it available yet? If so, who besides Amazon would carry it? And likewise for the HGST SSD800MM?

We commonly review products before such availability and I might keep my eyes open on the Amazon links for the card. As for the HGST 12Gbps SAS SSDs, I somehow don’t think we are going to be seeing those available through retail means anytime soon, keeping in mind thjat they are still a new and very hard to come by item.

Thanks ahead though for using our links!

The “wow” for the performance numbers. Again, wow 8) and thanks for the informative review. Would like to buy, but am going to have to save pennies for awhile.

Ok, so for example, (8)Internal / (8)External , so does this “flexibility” mean, I can simply connect 16 Drives “Internally” to the Raid card, and for example utilize all 16 in a Raid-10 ???

If you want to connect only internal drives using the 8885 then you would want to use a backplane with expanders, as physically, only 8 directly cabled drives can be connected to the internal ports on this model. However if you had an externla drive enclosure attached to this model, then you could use the external porsts in combination with the internal. With the use of an expander based enclosure, you would be able to see all the drives in the enclosure through one connection (single point to point cable from controller to enclosure). You could also use a 16… Read more »

Thank you! Always great to have the manufacturer jump in to elaborate!

Hi
Do you know if the new series 8 follows the same nature as previous one series 6 and 7, I mean, they seem to shine at high queue depths, but can you tell me if the made progress on random 4K QD1? Thank you

Hi Ricardo, Adaptec has been working on improving lower queue depth performance and the up-comming release of firmware expected at the end of 2013/beginning of 2014 should reflect these changes in series 7 and 8 performance numbers. However, even when these changes are implemented, queue depth 1 performance is expected to be low compared to more common IO depth performance applications. Especially since at IO depth 1, the full latency of every stage in the IO path is exposed – from application, driver, command thread, drive and all the way back. At all times, only one stage is active. All… Read more »

Thank you for the answer Adaptec. I’ve been using Adaptec 6405 with ZMM module connecting a pair of samsung 830 ssd specifically on windows environment. I learned that Dynamic mode is the best suited for windows environment (every type of sequencial and random nature). Ok I know the benchmarks (wherever they are) don’t tell the true story and my “slow” 6405 is really fast scanning a single seagate barracuda 7200.10 at 920mb/s (all cache enabled when protected by zmm) and drives cache itself). I asked before about random 4k QD1 because each manufacturer do their controllers specifically for one environment,for… Read more »

It does not help with read/writes. It is just a replacement for a BBU. BBU has problems with maintaining voltage, in some cases you will have to empty it to gauge how much power it has, or to increase how it’s life expectancy. That is the downside to this, it cannot keep power in check for a too long of period of time. And you will have to empty the BBU and recharge it again. That means in the mean time of a few hours it will use passthrough instead of backed. In most cases it is not tolerateble to… Read more »

Are throughput test done in RAID 5 mode?

Unfortunately all I gained from this article was that you are happy Adaptec has raid controllers. If those charts included a performance comparison to a 9271 or even a 9260 I’d have some idea how an LSI benchmarks are in relation to the new adaptec. Just because it is 12G or PCI 3.0 that doesn’t mean it is faster, just that it has access to more bandwidth however the processor may be so slow it gains nothing.

Dear all, is there Host based adopter (HBA) that is compatible with ubuntu operating system.
