Samsung PM1653 (MPN MZILG30THBLA-00A07) delivers a clear generational step over MZILT30TB by moving to SAS 24Gb/s, effectively doubling host-interface bandwidth while scaling to 4,300/2,400 MB/s sequential performance and up to 800K/135K IOPS for latency-sensitive enterprise workloads. At 30.72 TB, its 128-layer V-NAND TLC design pairs high-density deployment with 1 DWPD and 56,064 TBW endurance, making it a stronger fit than the prior generation for space-efficient virtualization clusters, mixed database workloads, and read-intensive storage tiers.
With an endurance rating of 56,064 TBW and 1 DWPD, the MZILG30THBLA-00A07 is built to sustain very heavy write activity across its service life. In typical enterprise workloads, this level of endurance means it can confidently serve as a long-term system or data drive, delivering worry-free operation for many years under normal usage conditions. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and protect metadata integrity if power is suddenly interrupted. Its ultra-low UBER of 1.0E-17, together with a 2.5 million-hour MTBF, indicates an exceptionally low risk of uncorrectable read errors and strong overall dependability for business-critical deployments.
1. The SAS 24Gb/s interface provides dual-port, enterprise-class connectivity that improves high-availability storage designs and keeps mission-critical systems online during path failover.
2. With 4300 MB/s sequential read performance, this SSD accelerates large-block workloads such as database backup restores, analytics scans, and media streaming.
3. Its 800,000 random read IOPS enables fast response under highly concurrent transaction loads, helping virtualized databases and OLTP platforms serve more users with lower contention.
4. Rated for 1 DWPD, the drive is tuned for read-intensive enterprise deployments, giving data centers a balanced mix of usable endurance, predictable lifespan, and lower storage cost.
5. Built on Samsung 128-layer 3D TLC V-NAND and delivering a typical latency of 90 µs, it helps enterprise applications achieve consistent responsiveness while maintaining solid density, power efficiency, and reliability.
Lower capacity reference: 15.36 TB Higher capacity reference: 61.44 TB At 30.72 TB, this drive sits in the sweet spot of the family. Compared with 15.36 TB, it gives meaningfully more headroom for data growth, denser consolidation, and longer refresh cycles without changing the expected enterprise-class throughput profile. Compared with 61.44 TB, it delivers a more balanced acquisition cost, lower risk of overprovisioning, and easier budget scaling while keeping performance in the same practical band. It is especially well suited for mid-sized virtualization clusters, such as hosting boot and primary data volumes for about 40 to 60 mixed-workload virtual machines.
Q: Is MZILG30THBLA-00A07 suitable for a write-heavy database server?
A: It can support mixed or moderate write database workloads, but for strongly write-heavy servers, 1 DWPD may be limiting. We recommend evaluating daily write volume against the 30.72TB capacity.
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 30.72TB drive write per day during its warranty period, aligned with its 56,064TB total 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 unexpected outages, which is critical for enterprise stability, data integrity, and transactional consistency.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for performance-sensitive and write-intensive enterprise workloads, while RAID 5 or 6 may suit capacity-focused environments. The best choice depends on performance, redundancy, and rebuild priorities.
