The SSDSC2BA400G3T stands out in the SATA enterprise tier by pairing 25nm HET MLC with 10 DWPD and 7.3 PBW endurance, delivering a rare combination of 500/460 MB/s throughput and 75K/32K IOPS for write-intensive OLTP, logging, and virtualization workloads. Compared with the earlier SSDSC2BA400G3, this later DC S3700 refresh gives architects a more current, drop-in qualified build while preserving the same high-endurance profile and steady-state performance consistency that made the platform a benchmark for mixed-workload reliability.
With an endurance rating of 7,300 TBW and 10 DWPD, the SSDSC2BA400G3T is designed for intensive write-heavy enterprise workloads and can sustain the equivalent of rewriting its full capacity 10 times per day throughout its rated service life. In typical real-world deployment, this means it can serve very comfortably as a boot or system drive for many years, while also providing ample endurance headroom for caching, logging, and other demanding applications. For enterprise reliability, built-in power loss protection (PLP) helps preserve in-flight data and protects 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 unrecoverable bit error rate, which, together with the 2 million hour MTBF, supports high data integrity and dependable operation in business-critical environments.
1. The SATA interface provides drop-in compatibility with mainstream enterprise servers and storage arrays, while its full-bandwidth sequential performance helps accelerate backup, imaging, and large-file streaming workloads without requiring a PCIe platform change.
2. Strong random-read capability enables the drive to sustain responsive performance under metadata-heavy databases, virtual desktop boot storms, and read-intensive web infrastructure.
3. Its high write-endurance rating makes it well suited for logging, caching, and mixed-workload applications that rewrite data aggressively every day without quickly consuming drive life.
4. The high-endurance MLC NAND is tuned for enterprise reliability, giving operators a better balance of sustained performance, write durability, and predictable behavior than consumer-grade flash.
5. Very low typical latency helps reduce storage wait time for transactional applications, improving quality of service and keeping latency-sensitive workloads more consistent under load.
Lower capacity reference: 200 GB Higher capacity reference: 800 GB In this series, the 400 GB option is the practical sweet spot. Compared with the 200 GB model, it gives meaningfully better space headroom for OS images, logs, swap, and application growth, reducing early capacity pressure in always-on enterprise environments. Compared with the 800 GB version, it usually preserves nearly the same mainstream enterprise SATA performance profile while offering a more attractive cost point and better budget efficiency per node. It is well suited for mid-scale virtualization clusters, such as hosting boot and infrastructure volumes for about 40 to 60 general-purpose virtual machines.
Q: Is SSDSC2BA400G3T suitable for a write-heavy database server?
A: Yes. With 10 DWPD, 7300 TBW, 25nm HET MLC NAND, low 45 µs typical latency, and SATA 6Gb/s, it is well suited for write-intensive database and enterprise workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 10 full drive writes per day. For a 400 GB SSD, that equals about 4 TB of writes daily, aligned with its 7300 TB 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 sudden outages, reducing corruption risk and improving reliability in transactional or cache-sensitive server environments.
Q: What RAID level is recommended for this SSD?
A: For most enterprise deployments, RAID 10 is the preferred choice. It combines strong write performance, low latency, and redundancy, making it a solid match for database and write-heavy server workloads.
