The Micron 1100 256GB (MTFDDAV256TBN-1AR1ZABYY) is a strong fit for read-intensive SATA deployments such as client imaging, OS boot drives, light VDI, and edge appliances, combining 530/500 MB/s sequential performance with up to 55,000/83,000 IOPS in a low-friction 6Gb/s upgrade path. Compared with typical planar-TLC SATA drives in the same class, its 3D TLC architecture and 120TB endurance deliver a better balance of sustained responsiveness, write durability, and long-term fleet reliability.
With an endurance rating of 120 TBW, this 256GB SSD can sustain about 33GB of host writes per day for 10 years, which is well above the write volume of a typical OS, boot, and application drive. In practical terms, for common read-heavy client or embedded system workloads, it is well suited as a long-life system disk with comfortable endurance headroom. For reliability, the specified UBER of 1.0E-15 means the drive is designed for a very low rate of uncorrectable bit errors, supporting dependable data reads in normal operation. This model does not include power-loss protection (PLP), so while it is appropriate for stable-power environments and standard system-drive use, applications with frequent unexpected power interruptions or in-flight write protection requirements should consider that limitation in system design.
1. The SATA interface enables straightforward drop-in deployment across legacy and mixed-generation enterprise servers, reducing upgrade friction and qualification effort.
2. Its top-end sequential read performance helps accelerate full-dataset scans, system boot, and large file retrieval in read-centric storage tiers.
3. Strong random read capability sustains responsive access to scattered records, making it well suited for virtualized workloads, OLTP databases, and metadata-heavy applications.
4. With an endurance rating of [dwpd] DWPD, the drive is positioned to handle predictable enterprise write cycles while supporting longer service life and lower replacement frequency.
5. Built on 3D TLC NAND and paired with a typical latency of [latency] µs, it balances flash density, cost efficiency, and fast response times for mainstream data center workloads.
Lower reference capacity: 128GB Higher reference capacity: 512GB At 256GB, this SSD sits at the sweet spot of the family. Compared with the 128GB version, it provides much better headroom for OS images, logs, swap, and application growth, reducing early capacity pressure in always-on enterprise environments. Compared with the 512GB model, it preserves essentially the same class of sequential throughput and random IOPS while keeping acquisition cost and fleet-level budget more efficient. This makes 256GB a practical choice for small-to-midsize virtualization clusters, such as hosting boot volumes for about 40 to 60 infrastructure or application VMs.
Q: Is MTFDDAV256TBN-1AR1ZABYY suitable for a write-heavy database server?
A: Not ideally. With 3D TLC NAND, 120 TBW endurance, SATA interface, and no power loss protection, this 256GB SSD is better suited for read-intensive or light mixed workloads than write-heavy database servers.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: Based on 120 TBW and 256GB capacity, the drive supports about 469 full drive writes total. Assuming a 5-year warranty, that equals roughly 0.26 drive writes per day.
Q: Does it include power loss protection (PLP) and why is that critical?
A: No, it does not include PLP. PLP is critical in enterprise environments because it helps protect in-flight data and metadata during sudden power loss, reducing corruption risk and improving data integrity.
Q: What RAID level is recommended for this SSD?
A: For business-critical use, RAID 1 or RAID 10 is recommended, depending on capacity and performance needs. They provide redundancy and better fault tolerance than RAID 0, especially without PLP support.
