Compared with the earlier SSDSC2KG019T8, the SSDSC2KG019TZ in the D3-S4620 Series advances to Intel 144-layer 3D TLC, delivering a stronger enterprise SATA balance of 3 DWPD endurance, 13,100 TBW, and sustained 550/510 MB/s performance at 1.92TB. Its 91,000/41,000 random IOPS profile makes it a particularly strong fit for write-intensive virtualization, database logging, and mixed-read/write edge servers that need higher endurance and better long-term consistency than typical SATA SSDs in the same class.
With an endurance rating of 13,100 TBW and 3 DWPD, the SSDSC2KG019TZ is designed for sustained enterprise write workloads and can comfortably support years of intensive daily operation. In typical deployment, this level of endurance means it can serve reliably as a high-write system, cache, or application drive with ample margin for long-term use. Its enterprise-grade reliability is further strengthened by power loss protection, which helps preserve in-flight data and metadata during unexpected outages, reducing the risk of corruption or incomplete writes. An UBER of 1.0E-17, together with a 2 million hour MTBF, indicates a very low probability of unrecoverable bit errors and strong overall dependability for business-critical environments.
1. The SATA 6Gb/s interface enables drop-in deployment across mainstream enterprise backplanes and legacy server platforms, simplifying upgrades without changing the storage architecture.
2. With sequential read performance of 550 MB/s, this drive accelerates large-file access such as OS image delivery, analytics dataset loading, and backup restore workflows.
3. Its random read capability of 91,000K IOPS supports dense virtualization and read-heavy database workloads by sustaining fast access to small, scattered data blocks under concurrency.
4. Rated at 3 DWPD, the SSD is built for write-intensive enterprise use, giving IT teams the endurance headroom needed for logging, caching, and mixed transactional workloads over its service life.
5. Built on Intel 144-layer 3D TLC NAND with a typical latency of 36 µs, it combines high flash density with consistently fast response times for predictable application performance in latency-sensitive environments.
Lower capacity reference: 960GB Higher capacity reference: 3.84TB In this SSD family, the 1.92TB model sits at the sweet spot. Compared with the 960GB version, it gives much better headroom for OS images, application growth, logs, and overprovisioning, reducing the risk of early capacity pressure while keeping similar enterprise-class sequential and random I/O behavior. Compared with the 3.84TB option, it typically delivers the best balance of acquisition cost, usable capacity, and performance consistency. It is especially well suited for mid-scale virtualization clusters, such as shared boot and application storage for about 40 to 60 general-purpose virtual machines.
Q: Is SSDSC2KG019TZ suitable for a write-heavy database server?
A: Yes. With 3 DWPD, 13,100 TBW endurance, 36 µs typical latency, and Intel 144-layer 3D TLC NAND, SSDSC2KG019TZ is well suited for write-intensive database and transaction-heavy enterprise workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 3 DWPD, meaning it can sustain about three full 1.92TB drive writes per day throughout its warranty period, aligned with its 13,100 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 outages, which is critical for maintaining data integrity, consistency, and reducing corruption risk in enterprise systems.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for this SSD in performance-critical environments, as it balances strong read/write performance, low latency, and redundancy better than RAID 5 for write-heavy enterprise applications.
