Compared with the earlier SSDSC2BB240G7, the SSDSC2BB240G701 refreshes the 240GB DC S3520 with a later 3D MLC SATA platform that emphasizes higher endurance confidence, delivering 590TBW at 1 DWPD while preserving drop-in SATA 6Gb/s compatibility. For boot, cache, and read-centric server tiers that still require dependable write tolerance, it pairs steady 450/380 MB/s throughput with up to 65,000/16,000 IOPS, giving it a more balanced durability-to-performance profile than typical entry SATA SSDs in its class.
With an endurance rating of 590 TBW and 1 DWPD, the SSDSC2BB240G701 can sustain writing its full 240 GB capacity every day for about five years, which is well above the needs of most typical OS, boot, and mixed business workloads. In practical terms, for use as a system drive or general enterprise read-intensive drive, this level of endurance provides long service life and dependable write capability with substantial margin under normal operating conditions. For enterprise reliability, the drive includes power-loss protection (PLP), which helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving recovery confidence. Its UBER of 1.0E-17 and 2 million-hour MTBF indicate a very low unrecoverable bit error rate and strong long-term reliability expectations, making it a trustworthy choice for business and data-center deployments.
1. The SATA 6Gb/s interface enables straightforward integration into mainstream enterprise storage backplanes, while the 450 MB/s sequential read speed keeps boot volumes, log replay, and bulk data access consistently responsive.
2. With 65,000 random read IOPS, this drive handles metadata-heavy workloads such as virtualization, indexing, and OLTP far more smoothly by reducing storage bottlenecks under concurrent access.
3. Rated at 1 DWPD, it is well suited for mixed-use enterprise deployments that need predictable endurance for daily rewrites without overpaying for unnecessarily high write tolerance.
4. Built on 3D MLC NAND, it offers a strong balance of retention, endurance, and performance consistency that fits business-critical applications better than lower-end flash designs.
5. The 40 µs typical latency helps accelerate transaction response times and improves QoS stability, which is especially valuable for latency-sensitive databases and virtualized workloads.
Lower capacity reference: 120 GB Higher capacity reference: 480 GB Capacity positioning analysis: In this series, the 240 GB model sits in the sweet spot for mainstream enterprise deployment. Compared with the 120 GB version, it gives much better headroom for OS images, logs, patch growth, and overprovisioning, reducing the risk of early capacity pressure. Compared with the 480 GB option, it delivers nearly the same everyday enterprise SATA performance while keeping acquisition cost and per-node storage budget under tighter control. It is especially well suited for small-to-mid-sized virtualization clusters, such as providing boot and utility storage for about 20 to 30 infrastructure or application servers.
Q: Is SSDSC2BB240G701 suitable for a write-heavy database server?
A: Yes. With 3D MLC NAND, 1 DWPD endurance, and 590 TBW, SSDSC2BB240G701 is suitable for write-intensive database workloads, especially where consistent latency and enterprise-grade reliability are required.
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 support one full 240 GB drive write per day throughout its warranty period, aligning with its 590 TBW endurance specification.
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 generally recommended for this SSD in database or virtualization environments, as it balances performance, redundancy, and write efficiency better than parity-based RAID levels.
