The Micron 6550 ION MTFDLBQ61T4THL-1BK1DFCYYR is purpose-built for read-intensive hyperscale workloads such as CDN edge caching, AI data lakes, object storage, and large-scale content repositories, combining 61.44TB of 3D TLC capacity with PCIe Gen5 performance up to 14,000 MB/s read and 2,000,000 IOPS to maximize storage density per slot. With 0.3 DWPD and 33,000 TBW, it delivers a compelling balance of endurance, throughput, and capacity that lets architects reduce rack footprint, power, and cost per TB versus lower-capacity enterprise NVMe SSDs in the same deployment tier.
With an endurance rating of 33,000 TBW and 0.3 DWPD, the MTFDLBQ61T4THL-1BK1DFCYYR is built to handle sustained daily write activity over a long service life in typical enterprise use. In practical terms, for common OS, boot, and read-intensive application workloads, this level of endurance is more than sufficient to support stable operation for many years, including use as a dependable system drive over a 10-year planning horizon. This drive also includes Power Loss Protection (PLP), which helps preserve in-flight data and maintain metadata integrity during unexpected power interruptions, reducing the risk of corruption or downtime. Its enterprise-class UBER of 1.0E-17 indicates an extremely low unrecoverable bit error rate, providing a high level of data integrity assurance for business-critical environments.
1. The PCIe Gen5 NVMe interface provides the bandwidth headroom needed to keep GPU servers, high-core-count databases, and modern storage nodes fed without the bus becoming the bottleneck.
2. Its ultra-fast sequential read performance accelerates large-file streaming, analytics scans, and AI model loading, helping reduce job start times in data-intensive environments.
3. The exceptionally strong random read capability is ideal for virtualization, metadata-heavy workloads, and high-concurrency online services where rapid small-block access drives user responsiveness.
4. Built with 3D TLC NAND and a read-optimized endurance profile, this SSD is well suited for content delivery, data lakes, and scale-out infrastructure that prioritize capacity efficiency and stable enterprise reliability over heavy daily rewrites.
5. The very low typical latency helps applications return data more predictably, improving tail-latency behavior in real-time analytics, transactional platforms, and latency-sensitive cloud services.
lower_capacity: 30720GB higher_capacity: 122880GB The 61440GB model sits at the sweet spot of this SSD family. Compared with the 30720GB version, it provides much better headroom for data growth, denser consolidation, and longer refresh cycles without changing the expected enterprise-class sequential throughput or random IOPS profile. Compared with the 122880GB option, it delivers a more balanced cost-per-deployment while still offering substantial usable capacity and strong performance consistency. In practice, this makes 61440GB especially well suited for mid-to-large virtualization clusters, scale-out databases, or roughly 250 to 350 mixed-workload VDI desktops.
Q: Is MTFDLBQ61T4THL-1BK1DFCYYR suitable for a write-heavy database server?
A: This model is better suited for read-intensive or mixed workloads. With 0.3 DWPD and 33,000 TBW, it may not be the ideal choice for consistently write-heavy database environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 0.3 drive writes per day, meaning the 61.44TB capacity can be fully overwritten about 30% of once per day throughout the supported warranty period.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP helps preserve in-flight data and metadata during unexpected outages, which is critical for maintaining data integrity and reducing corruption risk.
Q: What RAID level is recommended for this SSD?
A: RAID recommendation depends on workload and redundancy goals. For performance and fault tolerance, RAID 10 is commonly preferred; for capacity-efficient protection, RAID 5 or RAID 6 may be considered.
