The PM1633 MZILS3T8HCJM00D4 is an ideal choice for mission-critical SAS server tiers and virtualization clusters, pairing 3.84 TB of Samsung V-NAND 3D TLC with 7,008 TBW endurance and consistent 1,350/1,250 MB/s performance to extend the value of existing 12 Gb/s SAS infrastructure. Compared with MZILS3T8HCJM-000D4, this newer MPN delivers a generational lifecycle-refresh advantage with drop-in platform continuity and the same proven 160,000/18,000 IOPS at 1 DWPD, helping reduce requalification risk versus moving to a different SSD family.
With an endurance rating of 7008 TBW and 1 DWPD, the MZILS3T8HCJM00D4 is designed to support writing its full capacity once per day throughout its rated service life, which is more than sufficient for typical enterprise system-boot, virtualization, and mixed business workloads. In practical terms, under normal OS, application, and log usage, this level of endurance provides long-term, worry-free operation and ample write headroom for sustained daily use. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and protects metadata integrity during unexpected power interruptions, reducing the risk of corruption and unplanned recovery events. Its UBER rating of 1.0E-17 indicates an extremely low probability of unrecoverable bit errors, supporting high data integrity expectations in mission-critical environments, while the 2 million hour MTBF further reflects strong overall reliability.
1. The SAS 12.0 Gbps interface provides dual-port enterprise connectivity and proven back-end compatibility, making this drive a dependable fit for high-availability storage arrays and mission-critical servers.
2. With 1350 MB/s sequential read performance, it accelerates large-block data access for faster backup restores, analytics scans, and VM image loading in shared storage environments.
3. Delivering 160,000 K IOPS random read with 110 µs typical latency, the drive supports highly responsive transaction processing and helps reduce storage wait time in dense virtualized workloads.
4. Rated at 1 DWPD, it offers predictable endurance for read-centric enterprise deployments where consistent daily write capability and long service life are both essential.
5. Built with Samsung V-NAND 3D TLC, it balances enterprise-class capacity, power efficiency, and cost effectiveness for scaling mainstream data center storage.
Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB In this series, the 3.84 TB model sits at the sweet spot. Compared with the 1.92 TB version, it gives much more headroom for OS images, application binaries, logs, and short-term data growth, reducing early capacity pressure without changing the expected enterprise-class read/write and random IOPS profile. Compared with the 7.68 TB option, it usually delivers the best balance of acquisition cost, usable capacity, and steady performance for mainstream deployments. It is especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for about 40 to 60 business workloads.
Q: Is MZILS3T8HCJM00D4 suitable for a write-heavy database server?
A: MZILS3T8HCJM00D4 is better suited for mixed-use or read-intensive database workloads. With 1 DWPD and 7008 TBW, it can handle steady writes, but not extremely write-heavy enterprise environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This SSD is rated at 1 DWPD, meaning it can sustain one full 3.84 TB drive write per day throughout its warranty period, within the specified endurance limits.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical because it helps preserve in-flight data and metadata during sudden outages, reducing corruption risk and improving storage reliability.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for this SSD in performance-sensitive server environments, especially databases. It provides strong read/write performance, redundancy, and faster rebuild behavior than parity-based RAID levels.
