The migration to smaller 2.5" HDD's and SSD's has created a need for quality converters for enterprise applications. In many cases, extensive existing infrastructure would require a large investment to replace, and that is not always an option.

Utilizing SSDs in the server has become far more commonplace as complex caching and tiering systems are becoming more widespread. Placing SSDs on the other end of a networking connection in NAS and SAN environments is not always the best option. The key to getting the most performance out of flash solutions is to keep the SSD's as close to the processor as possible, maximizing performance, and keeping latency as low as possible.

The same approach with more energy efficient 2.5" HDD's also necessitates the use of drive bay converters to continue the use of existing servers.

In order to deliver a solution that allows the easy placement of the SSDs into the server requires a product that does not hamper the performance of the underlying storage. Many of the available drive-bay converters on the market can hamper the performance of the HDD or SSD, defeating the purpose of keeping the flash in the server in the first place.

The Icy Dock MB982IP-1S-1 is designed to provide that easy conversion from a 2.5" to a 3.5" drive with absolutely no impact to the performance of the underlying storage solution. The design provides essentially an unaltered connection between the SAS port on the server and the SSD or HDD.

To test the converter we are utilizing the fastest SSD interface at our disposal, 12Gb/s, and the Toshiba PX02SMF080 (reviewed here). The Toshiba PX02SMF080 is a cutting-edge 12Gb/s SSD. The Toshiba PX02SMF080 is the first publicly available 12Gb/s SSD, and to this date there is only one other 12Gb/s SSD available.

Pairing this with the LSI 9300-8e, the only publicly available 12Gb/s HBA, creates a test situation that is rather unfair for the Icy Dock converter. When the Icy Dock MB982IP-1S-1 was designed, the 12Gb/s SAS specification was still on the horizon, and there was virtually no means of determining if the converter can handle the massive speeds of the 12Gb/s specification without interfering with performance.

Specifications

The Icy Dock converter comes in two versions, one for consumer, and one for enterprise applications. The SAS version we are testing today comes with a wide compatibility for any 7mm, 9.5mm, 12.5mm or 15mm 2.5" SAS drive, be it an HDD or an SSD.

The solid metal construction actually is rather light, weighing in at a mere .72 pounds. This light weight detail is surprising considering the heft and rugged construction of the unit.

Drive installation is tool-less, there are no screws required. This is accomplished via the Icy Dock True Fit system, which we will take a closer look at in the following pages.

As we close the case over the SSD, we can see that the thin curved metal strips will hold the SSD in the case firmly. These strips create what Icy Dock refers to as Smart-Fit technology. This system works beautifully, securing the SSD into the case snugly, without damaging the surface of the drive. The snug fit protects against vibration in multi-drive deployments, and compresses enough to hold the wide range of drive sized supported by the Icy Dock.

The installation of the drive does not require any fasteners, which is bonus when deploying a large number of converters. Another key aspect is the sliding action of the converter. As the lid of the Icy Dock closes, the drive slides forward and mates to the SAS connector. This easy method works smoothly and without issue. On cheaper converters, we have suffered from broken SAS and SATA connections due to misaligned connectors. The Icy Dock provides one of the smoothest actions we have experienced with this type of solution.

We have overlaid the results of our random 4K write testing to illustrate the performance with the converter and a direct cable connection to the HBA. Each dot represents performance during one second of the test, and we record data for five minutes for each Queue Depth. This method allows us to measure performance variability with a high level of granularity. We can see that the majority of results are overlapping, and the performance remains consistent both with and without the converter.

The lines represent the average speed during the measurement window. We can see that the SSD actually has a faster speed with the converter, but a word of caution. The converter does not make the SSD faster, but allows the SSD to perform very well within its normal range of performance. Small differences such as these fit within the +/- tolerance of 5% for a typical test, as flash solutions tend to have a bit of variability, even in steady state conditions.

Our 4K random read test again points out that there is no difference in performance with the converter. The majority of the black dots are covered, due to the device offering the same level of performance with the converter as when directly attached. This is truly spectacular performance from both the SSD and the converter.

Our write percentage testing illustrates the varying performance of each solution with mixed workloads. The 100% column to the right is a pure write workload of the 4K file size, and 0% represents a pure 4K read workload.

This more demanding test shows the Icy Dock converter allowing the 12Gb/s SSD to deliver full performance. The Icy Dock converter aces our performance tests, illustrating that it does not affect performance of the SSD.

Final Thoughts

The Icy Dock 3.5" to 2.5" drive-bay converter features a high quality construction designed for ease-of-use and drive protection. The sturdy steel construction provides an extremely tough exterior that will protect the drive inside from any of the typical bumps and scratches experienced during installation.

The Icy Dock Smart-Fit technology holds the drive snugly, regardless of the thickness. This system protects against vibration during use, and also does not scratch or mar the surface of the drive. We have used several adaptors in the past that can actually leave scratches and marks on the exterior of the drive. While these small marks only affect the aesthetic quality of the drive, they certainly are not desirable. The Icy Dock Smart-Fit system holds the drive snugly, without damaging it. A neat aspect of the Smart-Fit technology also is the lack of a need for fasteners to install the drive - this simplifies installation tremendously.

When the drive is placed into the converter, the user also does not have to worry about lining up the SAS port. The mating of the drive to the SAS connector happens through an automatic sliding action as the converter is closed. This type of system typically makes us leery, as many cheap converters on the market will not line up correctly and can actually break or snap off the SAS connections on the SSD or HDD.

With a very rare 12Gb/s SSD being installed into the converter, there was a bit of apprehension the first time we closed the lid. The sliding action worked perfectly, the best we have experienced actually, and mated correctly with absolutely no unnerving resistance. We opened and closed the converter a number of times to test the function, and users will have no issues with this system - it works flawlessly.

High performance SSDs and HDDs can generate quite a bit of heat during use. The excellent thermal ventilation slots, placed on all side of the converter, provide a tremendous amount of airflow that allows the device to stay nice and cool. We also noted the drive sets flush on the bottom of the converter case. This allows the heat to transfer to the case of the converter, essentially turning it into a large heatsink. This great feature allows for even better thermal dissipation.

In our testing, we can see that the converter applies zero overhead to the performance of even the fastest 12 Gb/s SAS SSDs available. Though the SSD scored faster in the test with the converter than connected directly to our HBA, we have to caution that the Icy Dock converter does not actually speed up the SSD, or allow it to break the laws of gravity. It just merely allows it to perform at its finest with no restriction, and the tests completed within the typical variation expected with flash devices.

The Icy Dock MB982IP-1S-1 is a high quality converter priced very competitively for the price conscious with a three year warranty. This is our first encounter with an Icy Dock solution in the enterprise area here at TweakTown, and it will not be the last. We will be using these converters in all of our server applications in the future. With its high quality and smooth function, we would recommend this to anyone looking for a SAS drive bay converter, easily winning the TweakTown Editor's Choice Award.
