Compared with the previous SSDSC2KB038T8, the SSDSC2KB038TZ01 advances the 3.84TB D3-S4520 platform to Intel 144-layer 3D TLC, providing a newer NAND generation while sustaining 550/510 MB/s SATA performance and 91,000/28,000 IOPS for stable datacenter operation. Its standout value is the combination of broad SATA 6Gb/s deployability with 1 DWPD and 18,200 TBW endurance, making it a stronger fit than the prior generation for read-centric virtualization, boot, and content-serving nodes that need long service life without changing server backplanes.
With an endurance rating of 18,200 TBW and 1 DWPD, the SSDSC2KB038TZ01 is built to handle sustained daily write activity over its full service life, making it well suited for demanding enterprise workloads. In typical real-world deployment, this level of endurance means it can comfortably serve as a high-write system or application drive for many years without endurance becoming a practical concern. For enterprise reliability, the drive includes power-loss protection (PLP), which helps preserve in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption and downtime. Its UBER rating of 1.0E-17 and 2 million hours MTBF further indicate a strong data integrity and reliability profile, giving procurement teams added confidence for business-critical environments.
1. The SATA enterprise interface enables broad drop-in compatibility with existing server and storage platforms, making upgrades simple while still delivering enough bandwidth for mainstream boot, logging, and read-heavy application tiers.
2. Its strong sequential read performance helps accelerate large file access, faster database snapshots, and shorter restore or analytics load windows in data center workflows.
3. High random read capability supports dense virtualization and transactional workloads by serving large volumes of small-block requests with less application-side queuing and better user responsiveness.
4. A one-drive-write-per-day endurance profile gives enterprises a predictable balance of lifespan and cost efficiency for mixed-use deployments such as content delivery, cloud infrastructure, and scale-out storage.
5. Built on Intel’s 144-layer 3D TLC NAND with very low typical latency, the drive combines mature flash density and power-efficient operation with fast response times that help reduce storage-induced delays in latency-sensitive services.
Lower capacity reference: 1.92TB Higher capacity reference: 7.68TB At 3.84TB, this model sits in the sweet spot of the series. Compared with the 1.92TB version, it gives significantly more headroom for data growth, overprovisioning, and workload consolidation without changing the expected enterprise SATA performance profile. Compared with the 7.68TB option, it usually delivers a better balance between acquisition cost, usable capacity, and deployment flexibility, avoiding overbuying in mid-scale environments. It is especially well suited for medium virtualization clusters, such as shared storage pools for about 60 to 80 mixed-application virtual machines.
Q: Is SSDSC2KB038TZ01 suitable for a write-heavy database server?
A: Yes. With 1 DWPD, 18,200 TBW, low 36 µs typical latency, and Intel 144-layer 3D TLC NAND, it is suitable for mixed-use and moderately write-heavy database workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 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 PLP. This is critical because it helps protect in-flight data and metadata during sudden power failure, reducing corruption risk and improving storage reliability.
Q: What RAID level is recommended for this SSD?
A: RAID choice depends on the application. RAID 10 is commonly recommended for databases needing strong performance and redundancy, while RAID 5 or 6 may suit capacity-focused environments.
