IOMETER: Our Standard Test (Steady State)

IOMETER: Our Standard Test (Steady State)

These results really do say it all for us. Naturally, they are a bit lower than when dealing with a “virgin”device, even after many hours of being hammered by intense workloads, the Intel 910 has not only kept the majority of its performance but is able to quickly pull itself back up to peak performance in short order. Compare and contrast this to the SandForce based RevoDrive3 x2 480GB which loses a significant portion of its power and requires either a full erasure or many hours of low I/O to gain it back.

As with the non-steady state results, our custom email server scenario doesn't play to this device's strong suit. However, while the results are indeed lower – thanks to the steady state of the NAND – they are much better than what a RevoDrive3 x2 480GB was able to accomplish. Those four controllers take every opportunity to clean their attached NAND and the differences it makes are tangible when compared to a SandForce based solution.

It is quickly becoming apparent that Intel made the correct decision to not use LSI/SandForce SF2281 controllers for their 910. Intel's enterprise level drive simply thrives in scenarios more indicative of real world, long term usage scenarios and while the RevoDrive3 continues to stumble, this model implacably moves forward like the juggernaut it is. Of course, the 910 is still being hampered by its OS level RAID implementation, but the four “drive” results are extremely impressive nonetheless.

As expected, the results are close to what they were originally and while the Intel 910 does indeed post excellent numbers, so too –to a much lesser extent- does the ReovDrive3.

Adobe CS5 Load Time / Firefox Portable Performance

Adobe CS5 Steady State Load Time


Photoshop is a notoriously slow loading program under the best of circumstances, and while the latest version is actually pretty decent, when you add in a bunch of extra brushes and the such you get a really great torture test which can bring even the best of the best to their knees. To make things even more difficult we have first placed the devices into a steady state so as to help recreate the absolute worst case scenario possible

While it is very unlikely anyone would use an Intel 910 800GB for Adobe Photoshop, these results are indicative of what a workstation user would encounter by loading their most demanding program via the 910. It also –nearly- goes without saying that this device would make one of the most insane “overkill” game drives ever created and load times would become a thing of fleeting memory. While ten thousand dollar game systems are few and far between, we know what we would use as an additional “drive” in such a build.


Firefox Portable Offline Steady State Performance


Firefox is notorious for being slow on loading tabs in offline mode once the number of pages to be opened grows larger than a dozen or so. We can think of fewer worse case scenarios than having 100 tabs set to reload in offline mode upon Firefox startup, but this is exactly what we have done here.

By having 100 pages open in Firefox portable, setting Firefox to reload the last session upon next session start and then setting it to offline mode, we are able to easily recreate a worse case scenario. Since we are using Firefox portable all files are easily positioned in one location, making it simple to repeat the test as necessary. In order to ensure repetition, before touching the Firefox portable files, we have backed them up into a .rar file and only extracted a copy of it to the test device.

As with the Adobe test, we have first placed the devices into a steady state.

Where this are very, very deep queue depth tests, the Intel 910 easily posts numbers so low that margin of error starts to play a major role in the results. But what is clear is the results are nowhere close to scaling in a linear fashion. It is obvious that the software RAID solution is reducing the performance somewha; but by the same token, the amount of horsepower which you do get is astonishing considering how limited the 910's CPU, cooling and even physical footprint requirements are.

Real World Data Transfers

Real World Data Transfers


No matter how good a synthetic benchmark like IOMeter or PCMark is, it can not really tell you how the device will perform in “real world” situations. All of us here at Hardware Canucks strive to give you the best, most complete picture of a review item’s true capabilities and to this end we will be running timed data transfers to give you a general idea of how its performance relates to real life use. To help replicate worse case scenarios we will transfer a 10.00GB contiguous file and a folder containing 400 subfolders with a total 12,000 files varying in length from 200mb to 100kb (10.00 GB total).

Testing will include transfer to and transferring from the devices, using MS RichCopy (set to 1 file depth) and logging the performance of the drive.

However, unlike our usual Real World tests, we will be running 6 instances of each test concurrently. To do this we have attached 6 high performance SSDs with each instance of MSRicopy either copying to the 910 or from the 910 to the SSDs. The results will then be combined to give the total throughput potential of this drive. This has been done for the simple reason this device is simply too powerful to use our standard Real World Methodoly with and even a RevoDrive3 x2 480GB would bottleneck the results long before the 910 became saturated.

Here is what we found.

These results just back up what IOMeter told us: the Intel 910 is simply stunning when dealing with large file sizes. Also as expected, while the four LUN results – especially the high performance numbers – are impressive, the 910’s small file performance does not scale all that efficiently and in some scenarios we could see leaving this drive in a four drive configuration, rather than having it configured as one large drive. Doing so would increase the potential small file performance by the most simple expedient possible: deepening the queue depth.

Conclusion

Conclusion


Intel’s 910 800GB is currently a dominating titan within the solid state drive market but with extreme performance and impressive longevity comes a price that will be staggering for many of our readers. But before the pitchfork-wielding enthusiast mob descends upon this four thousand dollar monster, let’s all take a deep breath and remember that Intel’s focus here is firmly pointed towards the enterprise market and to a lesser extent workstation consumers. In that respect, they’ve succeeded beyond the expectations of many professionals that populate this highly influential sector.

Other than initial startup cost, one of the primary reasons why SSDs aren’t more prevalent in the enterprise market is their lack of performance longevity. With the 910’s impressive engineering backbone in place Intel has succeeded in creating a drive that can dig itself out of a degraded state / steady state in the blink of an eye. Not only is this drive quick to claw its way back up to near-maximum performance but getting it into a degraded state in the first place is bloody difficult to say the least. Even after ten hours of constant hammering – or more than enough time to turn even a potent RevoDrive3 x2 480GB drive into a quivering puddle – performance levels were maintained and workloads were processed without it batting an eyelash. Even the slightest pause in testing gave the 910’s controllers enough time to start regaining some of their lost performance.

Unfortunately, even though the sequential and even steady state performance was undeniably impressive, the 910 is not going to be right for all consumers (professional and otherwise) and all scenarios. At lower queue depths most of the 910’s performance overhead will simply never be utilized outside of somewhat pointless synthetic tests. Only when you place deep queue I/O workloads upon it can the Intel 910 800GB really stretch its legs and outpace anything else we have tested to date. We believe Intel has done this on purpose so everything from choice of controller to NAND to lack of bootability can scream ‘Enterprise storage’ towards its intended market niche.

Satisfying the needs of the Enterprise market – where deep queue depths and extreme durability are not only the norm but requirements– is the 910’s main priority and it shows. This will however limit its appeal outside of this rather narrow optimal operating environment, but the hardware and firmware refinements have be carried out with such subtly and deftness that it is still a true joy to see it in action.

Looking at the larger picture, sometimes it is better to offer an elegant solution that’s narrowly focused rather than a brute force device which good at many things but excels at nothing. Intel has done just that as their 910 is very good when given the problems it was designed to solve.

For customers that want ultra high performance, reliable storage for a web server or an all round “cloud” storage server, the low CPU overhead, ease of use and nosebleed-inducing performance levels of Intel’s 910 will make it a truly stellar choice. To a lesser extent we could see this being an excellent fit for workstation consumers who require massive amounts of performance without excessive power draw and heat production. Even Virtual Machine users and gaming enthusiast with more money than good sense will likely be lusting after this drive and its insanely high performance capabilities.

In the end there really is only one thing we can say which best sums up the Intel 910: this is a Dam Good drive. As long as your needs fall within its clearly delineated operating parameters, its price and quirks are far out weighted by a long, long list of positives.
