Compared with SSDSA2CW300G301, the SSDSA2CW300G3 is the later lifecycle MPN, giving engineers a more current deployment target while retaining the proven Intel 320 Series 25nm MLC platform with 60 TBW endurance and stable SATA 3Gb/s performance. Its 300 GB capacity, 270/205 MB/s sequential throughput, and 39,500/23,000 IOPS profile make it a strong fit for read-centric boot, cache, and embedded control-plane workloads that need better latency consistency and media durability than typical client-grade SATA SSDs.
With an endurance rating of 60 TBW, the SSDSA2CW300G3 can sustain about 16 GB of host writes per day for 10 years, which is comfortably above the write volume of most boot-drive, office PC, POS, and thin-client environments. In practical terms, for typical read-heavy system-disk workloads, this level of endurance is well suited for long-term stable use without endurance becoming a concern. For reliability, built-in power-loss protection (PLP) helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and unclean shutdown issues. Its UBER rating of 1.0E-16 means an extremely low unrecoverable read error rate, supporting dependable data integrity in daily operation and giving buyers added confidence for business use.
1. The SATA 3Gb/s interface ensures broad compatibility with legacy enterprise servers and storage arrays, making it a practical drop-in upgrade for environments that prioritize stability over cutting-edge bandwidth.
2. With 270 MB/s sequential read performance, this drive helps accelerate OS boot, log access, and bulk file retrieval in read-focused business workloads.
3. Its 39,500 IOPS random read capability improves responsiveness for metadata-heavy applications such as virtualization, indexing, and transactional lookup tasks.
4. Rated at 0.1 DWPD and built on 25nm MLC NAND, the drive is best suited for read-centric enterprise deployments where cost efficiency and data retention matter more than sustained write intensity.
5. The 75 µs typical latency supports faster access to hot data, reducing application wait time and helping deliver more consistent service-level performance.
Lower capacity reference: 160 GB Higher capacity reference: 600 GB Typical performance reference for the same series: 160 GB: up to 270 MB/s read, up to 165 MB/s write, up to 39K random read IOPS, up to 21K random write IOPS 300 GB: up to 270 MB/s read, up to 205 MB/s write, up to 39K random read IOPS, up to 23K random write IOPS 600 GB: up to 270 MB/s read, up to 220 MB/s write, up to 39K random read IOPS, up to 23K random write IOPS The 300 GB model sits in the sweet spot of this series. Compared with the 160 GB version, it provides much better capacity headroom for OS images, logs, and application growth, reducing early replacement pressure. Compared with the 600 GB option, it delivers nearly the same enterprise-class responsiveness while keeping acquisition cost and $/IOPS more balanced. In practice, it is well suited for small-to-mid virtualization clusters, such as hosting boot and utility volumes for about 30 to 50 general-purpose virtual machines.
Q: Is SSDSA2CW300G3 suitable for a write-heavy database server?
A: Not ideally. With 0.1 DWPD and 60 TBW, SSDSA2CW300G3 is better suited for read-centric or mixed workloads rather than write-heavy database servers with sustained intensive daily writes.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 0.1 DWPD, meaning about 30 GB of writes per day on a 300 GB drive over its warranty period, assuming standard endurance qualification conditions.
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 mapping tables during unexpected outages, which is critical for data integrity, consistency, and enterprise storage reliability.
Q: What RAID level is recommended for this SSD?
A: For most business deployments, RAID 1 or RAID 10 is recommended to improve redundancy and maintain performance. RAID 5 may be used cautiously, but parity writes can increase endurance consumption.
