LSI 9265-8i MegaRAID Card vs Adaptec 6805 RAID Card – The Ultimate 6Gb/s RAID Showdown

With $45000 in hardware, over 100 hours spent pushing it to it’s limit, speeds of 2.7GB/s and over 461,800 IOPS, we are fairly certain that this RAID Controller and SSD review will be one of our most exciting reports to date, and not matched anytime soon.

Today we are going to go head-to-head with the LSI 9265-8i and the Adaptec 6805 RAID cards, these being two of the most powerful RAID devices available worldwide.  Grab a seat and buckle up as the hunt for the most powerful 6Gb/s RAID card solution is on! Who will emerge the victor?

Our goal is to showcase the raw power of both solutions under some of the most demanding situations. In the world of servers and datacenters, the most power in the smallest package is ‘King’ and both of these devices aim to deliver!

We have amassed several sponsors to partake in this shootout which assures us that we have top performing storage devices available today, both commercially and in the enterprise sector. The purpose is simply to  explore the absolute maximum of 6Gb/s RAID performance. In order to saturate these controllers, we had to bring in the heavyweights of SSD and EFD performance as the only way to illustrate the true capabilities of these controllers is to have the absolute fastest devices available today.

The competition for rack space between these companies is stiff as both look to dominate tomorrows data centers. With the explosion of data centers around the world, and high speed devices such as SSDs and EFDs coming into play, the onus is on these companies to capitalize on the game changing advances that have been made in the past few years in storage technology.

New emerging caching capabilities are coming to the forefront giving customers the option of upgrading-in-place. Only by finding ways to utilize these new technologies and the performance of the most robust solutions can these companies hope to gain rack space, and thus, market share. With some surveys indicating that 83 percent of data centers are planning significant expansions within the next 12 to 24 months, the stage is definitely set for a showdown with billions of dollars hanging in the balance.

The performance of these solutions can be broken into several categories and, by no means, do we intend to test cover all in this review. There are simply too many variables that these types of devices are designed to operate under.

We have broken the review into results from several standpoints. Performance and then of course, Price versus Performance. Performance will be broken into two segments, Throughput and IOPS.

  • Performance: IOPS and Throughput – In these scenarios, we will blatantly attempt to push these controllers to the very limit of their power. IOPS will consist of the small file random performance that is so demanding and throughput will be massive sequential power.
  • Price Vs. Performance -  These two solutions both represent the fastest devices from the two largest RAID card manufacturers. Both utilize a Dual Core ROC, which is a dual core processor for the RAID computations. The price of both devices is somewhat different so we will strive to answer, which is better bang for the buck?

The features and performance of both of these flagship controllers are just a few clicks away, so join us as we first take a look at the contenders…

    I can’t believe there’s no mention of TRIM. This article is a waste of time for anyone planning to use SSDs in RAID long term.
