Compared with the previous-generation MZWLO1T9HCJR, the MZ3LO1T9HCJR PM1743 Series moves to PCIe Gen 5.0 x4 and NVMe 2.0, delivering up to 13,000 MB/s sequential read and 2,500,000 random read IOPS for materially higher throughput and faster response in next-generation server platforms. Its 1.92TB Samsung V6 128-layer 3D V-NAND TLC design, combined with 1 DWPD and 3,504 TBW endurance, makes it a strong fit for read-intensive virtualization, scale-out analytics, and high-density cloud storage nodes that need Gen5 bandwidth without overprovisioning for write-heavy duty cycles.
With an endurance rating of 3,504 TBW and 1 DWPD, the MZ3LO1T9HCJR-00A07 is designed to handle writing its full capacity once per day across a standard enterprise service life, providing a very comfortable margin for typical OS, boot, and read-intensive application workloads. In practical terms, for use as a system drive or in common business servers with moderate daily writes, this level of endurance supports long-term, dependable operation without endurance being a likely concern. Its built-in power-loss protection helps preserve in-flight data and maintain metadata integrity if power is unexpectedly interrupted, reducing the risk of corruption during unplanned outages. An UBER of 1.0E-17, together with a 2.5 million-hour MTBF, reflects enterprise-class data integrity and reliability expectations, helping procurement teams deploy it with confidence in business-critical environments.
1. The PCIe Gen5 x4 interface with NVMe 2.0 provides a next-generation host path that removes storage bottlenecks in GPU servers, helping databases, analytics clusters, and AI nodes stay fed at full speed.
2. Its sequential read performance is built for bandwidth-heavy workloads, sharply reducing dataset staging, checkpoint loading, and large-file scan times in enterprise platforms.
3. With up to 2.5M random-read IOPS, the drive can sustain extremely dense transactional and virtualized environments, accelerating small-block access across OLTP, VDI, and metadata-intensive applications.
4. Rated at 1 DWPD and built on Samsung V6 128-layer 3D V-NAND TLC, it offers a balanced endurance profile for mainstream mixed-use deployments while keeping flash reliability and cost efficiency aligned.
5. A typical latency of 80 µs helps deliver consistently fast response under pressure, improving QoS for latency-sensitive services such as real-time analytics, high-frequency queries, and scale-out application tiers.
Lower capacity reference: 960GB Higher capacity reference: 3.84TB At 1.92TB, this SSD sits in the sweet spot of the series. Compared with the 960GB model, it gives much better space flexibility for OS images, application binaries, logs, and growth headroom, reducing early capacity pressure. Compared with the 3.84TB option, it usually delivers the best balance of acquisition cost, usable capacity, and standard enterprise performance without overprovisioning storage budget. In practice, it is a strong fit for a mid-sized virtualization cluster, such as hosting system and middleware volumes for 35 to 50 business VMs.
Q: Is MZ3LO1T9HCJR-00A07 suitable for a write-heavy database server?
A: It can support mixed or moderate write database workloads, but for truly write-heavy database servers, 1 DWPD may be limiting. We typically recommend higher-endurance enterprise SSDs for intensive sustained writes.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated at 1 DWPD, meaning it can sustain one full drive write per day over the warranty period. For 1.92TB, that equals about 1.92TB of writes daily.
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 sudden outages, which is critical for enterprise systems requiring data integrity, consistency, and reliable recovery.
Q: What RAID level is recommended for this SSD?
A: RAID 1 or RAID 10 is generally recommended for performance-sensitive and business-critical workloads, balancing redundancy and speed. RAID 5 or 6 may suit capacity-focused environments with acceptable write overhead.
