The Intel DC S3520 SSDSC2BB960G7 stands out in the 960 GB SATA enterprise class by combining 3D MLC NAND with 1 DWPD and 1,750 TBW, making it a strong fit for boot, caching, and read-centric virtualization tiers that need higher endurance than typical TLC-based SATA SSDs without moving to a higher-cost SAS or NVMe platform. Compared with the earlier SSDSC2BB960G701 revision, SSDSC2BB960G7 is the more deployment-ready choice for long-life data center refreshes, preserving the same proven 6Gb/s SATA performance envelope of up to 450/380 MB/s and 67K/16K IOPS while offering a later qualified MPN for cleaner lifecycle standardization.
With an endurance rating of 1,750 TBW and 1 DWPD, the SSDSC2BB960G7 is built to handle writing its full 960GB capacity every day throughout its designed service life. In typical business use such as OS boot, office applications, virtualization, and general server workloads, this level of endurance is more than sufficient for long-term deployment and can serve reliably as a system or mixed-use drive for many years. For enterprise reliability, the drive includes power-loss protection, which helps preserve in-flight data and metadata during an unexpected power interruption and reduces the risk of corruption. Its UBER of 1.0E-17, together with a 2 million hour MTBF, reflects enterprise-class data integrity and dependable operation, giving procurement teams confidence in its suitability for professional environments.
1. The SATA 3.0 interface enables seamless deployment in widely installed enterprise servers and storage arrays, reducing upgrade friction and avoiding platform redesign.
2. Its strong sequential read performance accelerates OS boot, backup recovery, and large-file access, helping data-intensive systems return to service faster.
3. High random read capability paired with low typical latency improves responsiveness for virtual machines, OLTP databases, and metadata-heavy workloads under concurrency.
4. A 1 DWPD endurance rating makes it a dependable fit for mixed-use enterprise environments, sustaining steady daily overwrite activity across its service life.
5. Built with 3D MLC NAND, the drive delivers a balanced combination of endurance, performance consistency, and data integrity that enterprises value in always-on infrastructure.
For the same series as MPN SSDSC2BB960G7, the next lower capacity is 800 GB, and the next higher capacity is 1.2 TB. At 960 GB, this drive sits in the sweet spot of the family. Compared with the 800 GB model, it gives noticeably more headroom for OS images, application data, and growth buffers, helping reduce early capacity pressure in steady enterprise use. Compared with the 1.2 TB option, it usually delivers a better balance of acquisition cost, usable capacity, and essentially similar enterprise performance. It is well suited for a mid-sized virtualization cluster, such as hosting boot and application volumes for around 40 to 60 business workloads.
Q: Is SSDSC2BB960G7 suitable for a write-heavy database server?
A: Yes. With 3D MLC NAND, 1 DWPD endurance, and 1750 TBW, SSDSC2BB960G7 is suitable for write-intensive database workloads, especially where consistent latency and enterprise 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 sustain one full 960 GB 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 helps preserve in-flight data and metadata during unexpected outages, which is critical for preventing corruption and maintaining storage consistency in servers.
Q: What RAID level is recommended for this SSD?
A: The best RAID level depends on your goal. RAID 1 is recommended for simple redundancy, RAID 10 for high database performance and protection, and RAID 5/6 for capacity-focused deployments.
