The Samsung PM1743 (MZWLO3T8HCLS) delivers a clear generational step over MZWLO3T8HBLS by moving to PCIe Gen5 x4 and pushing performance to 14,000/7,100 MB/s sequential and 2,500,000/250,000 IOPS random, giving latency-sensitive enterprise platforms substantially more headroom for virtualization, scale-out databases, and real-time analytics. With 3.84 TB of 6th-Gen 128-layer V-NAND TLC plus 1 DWPD and 7008 TBW, it stands out in its class as a balanced high-throughput mixed-workload SSD that improves throughput density without sacrificing enterprise endurance.
With an endurance rating of 7008 TBW and 1 DWPD, the MZWLO3T8HCLS is designed to sustain writing its full capacity once per day throughout its rated service life, which is more than sufficient for typical enterprise system-disk, boot, and read-intensive server workloads. In practical terms, under normal OS, application, logging, and virtualization usage patterns, this level of endurance provides long-term operational confidence and can comfortably support many years of stable deployment. For enterprise reliability, built-in power loss protection (PLP) helps preserve in-flight data and protect metadata integrity during unexpected power interruptions, reducing the risk of corruption and unplanned recovery events. Its UBER of 1.0E-17 indicates an extremely low probability of unrecoverable bit errors during reads, which is a key indicator of dependable data integrity for business-critical storage environments.
1. The PCIe Gen5 x4 interface unlocks next-generation host bandwidth, helping GPU servers, scale-out databases, and disaggregated storage nodes move data faster with less bus-side contention.
2. With up to 14,000 MB/s sequential read performance, the drive accelerates large-block workloads such as AI model staging, analytics scans, backup recovery, and high-speed content delivery.
3. Its 2,500,000 K IOPS random read capability is built for latency-sensitive enterprise applications, sustaining heavy VM, OLTP, and metadata access bursts without becoming the bottleneck.
4. Rated for 1 DWPD, it provides a balanced endurance profile for mainstream enterprise deployments that need predictable reliability across years of daily full-drive rewrites.
5. Built on Samsung V-NAND 6th-Gen 128-layer 3D TLC and backed by a typical latency of 75 µs, the drive delivers dense, power-efficient flash with consistently fast response times for mixed and read-intensive production workloads.
Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB At 3.84 TB, this SSD sits at the sweet spot of the series. Compared with the 1.92 TB model, it gives much better space headroom for OS, application, log, and growth planning, reducing the need for early drive expansion. Compared with the 7.68 TB version, it delivers a more balanced acquisition cost while keeping essentially the same enterprise-class read/write and IOPS behavior. This makes 3.84 TB especially well suited for mid-scale virtualization clusters, such as shared storage for about 40-60 mixed-workload virtual machines.
Q: Is MZWLO3T8HCLS suitable for a write-heavy database server?
A: Yes, it can support database workloads, but with 1 DWPD it is better suited for mixed-use or moderate write-intensive environments rather than extremely write-heavy, high-endurance database servers.
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 3.84 TB drive write per day across its warranty period, aligned with its 7008 TBW endurance rating.
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 power failure, which is critical for maintaining data integrity and reducing corruption risk.
Q: What RAID level is recommended for this SSD?
A: RAID 1 or RAID 10 is commonly recommended for this SSD in business-critical applications, as both provide redundancy, strong read performance, and better protection against drive failure.
