Micron 6550 ION SSD Review | A Data Center Essential

Following the success of the lower-end capacity models, Micron brings a massively beefed up SSD in the form of the Micron 6550 ION SSD. This offering  packs a whopping 61.44TB into the standard SSD stick.

Evidently, this is an SSD for hyper-scaling, or exponentially expanding, a setup that is not found in counsumer use cases. This is an SSD designed with cloud-providers in mind.

In a first-of-its-kind storage offering, this is Micron stepping into the arena of high-capacity and dare we say high stakes computing. In the company's own words, they are aiming for the AI evangelists and their lofty goals.

Cloud providers, content delivery networks (CDNs), and AI/ML data lakes are perfect use cases for this drive. The Micron 6550 ION SSD is purpose-built for environments that demand large-capacity drives with predictable read performance.

It doesn’t aim to break speed records; it excels in delivering consistent throughput at high capacity, and something cloud architects value when designing storage infrastructure that prioritizes efficiency and density.

What could this capacity achieve?

There are archival and research implementations for such a large storage capacity. In truth however, this is a stagnant data holding device. So the component is not ideal for frequent tinkering of stored data but rather read-only operations.

What it is good for though is to replace traditional HDDs. As we all know, the latter has a clunkier mechanism and thu loses out on heat generation metrics. Replacing existing HDD infrastructure with this SSD will greatly improve the functionality of your cloud network.

With sequential read speeds of up to 6,800 MB/s and write speeds up to 2,000 MB/s, it provides more than enough performance for workloads like boot operations, log analysis, and object storage reads.

While the Micron 6550 ION SSD isn’t designed to deliver the fastest write speeds, it hits the sweet spot for read-dominated tasks. Compared to spinning disks or lower-end SATA SSDs, the performance uplift is substantial.

Let's first set our standard for performance. A good SSD fares well on random read and write IOPS both. So what about the 6550? We are pleased to report that random read IOPS come in at up to 1mn, and random write IOPS at 110k. That's impeccable evidence that the drive can handle multiple simultaneous queries or user requests.

Translate this into practical terms and we have a champion for containerized applications that thrive on predictable throughput. The drive also benefits from Micron’s internal NAND tuning and firmware optimization, allowing for consistent sustained reads and reduced latency jitter.

This ultra-dense flash memory architecture enables Micron to deliver capacities of up to 30.72TB in a single U.2 form factor, helping enterprises shrink their hardware footprint without sacrificing storage volume.

At the heart of the Micron 6550 ION SSD is the company’s 232-layer 3D NAND technology, the most advanced NAND Micron has produced to date. The 232-layer NAND also brings improvements in power efficiency and data retention, making the 6550 ION more energy-efficient than previous-generation drives. It allows more data to be stored per wafer while reducing the cost per gigabyte, making the drive more affordable for massive deployments in data centers.

This strategic use of high-layer-count NAND is what makes the 6550 ION so compelling. It combines cutting-edge technology with a workload-specific focus that hits the mark for modern data infrastructures.

Power consumption is a major concern in today’s data centers. Not every facility can be backed by industrial solar panels. The Micron 6550 ION SSD addresses this with a design that caters to efficiency. In high-heat scenarios, perfomance minimizes excess heat production.

Typical power usage sits around 14W active and less than 5W idle. Going back to out earlier comparison, legacy HDDs consume significantly more under similar loads.

The Micron 6550 ION uses the U.2 (2.5-inch, 15mm) form factor, and no surprises there. The Solidigm D5-P5336 is a close competitor and has the same.

Beyond that, the 6550 ION uses the PCIe Gen4 NVMe interface. Capacities range from 3.84TB to 30.72TB, allowing organizations to scale according to their specific storage needs.

Finally, the 6550 ION supports end-to-end data path protection, power-loss protection, and SMART telemetry. These features meet a crucial demand. For the intended purpose which is something like a large database, the need is for easy monitoring at a large-scale.

Let's discuss the pros and cons of Micron 6550 ION SSD:

Pros:

·         Massive capacities up to 30.72TB

·         Efficient power profile for data center use

·         Excellent sequential read and IOPS performance

·         Optimized for read-intensive workloads

·         Uses cutting-edge 232-layer NAND

·         Consistent throughput with minimal latency jitter

·         U.2 form factor ensures easy integration into existing infrastructure

Cons:

·         Lower endurance (0.3 DWPD) not suited for heavy write tasks

·         Write speeds are moderate compared to high-performance SSDs

·         Best value only in large-scale, read-centric environments

·         Lacks onboard encryption for security-sensitive use cases

With capacities up to 30.72TB, a power-conscious design, and the latest NAND technology, Micron 6550 ION SSD delivers tremendous value. Especially in environments where read performance and cost per GB are top priorities. We believe the Micron 6550 ION is an investment worth making.
