The SSDPE21K375GAT is the later Optane DC P4800X 375GB revision, carrying forward the ultra-low-latency advantages of 3D XPoint while delivering 30 DWPD, 20.5PBW endurance, and up to 550K/500K random read/write IOPS—well beyond typical NAND SSD behavior for write-intensive databases, logging, and metadata acceleration. Compared with the earlier SSDPE21K375GA, the SSDPE21K375GAT is the stronger choice for current platform qualification and long-life deployment planning, preserving the same 2400/2000 MB/s performance profile and extreme endurance in a newer orderable MPN.
With an endurance rating of 20,500 TBW and 30 DWPD, the SSDPE21K375GAT is built for extremely write-intensive use and provides far more write headroom than a typical OS, boot, or application drive will ever consume. In practical terms, under normal server system-disk or mixed enterprise workloads, this endurance level supports long-term, worry-free operation and is well suited for continuous daily use with substantial safety margin. For enterprise reliability, integrated power-loss protection helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving shutdown resilience. Its ultra-low UBER of 1.0E-17 and 2 million hour MTBF indicate a very low probability of unrecoverable bit errors and a design aligned with dependable datacenter operation.
1. The PCIe 3.0 x4 NVMe interface gives this drive a low-overhead, host-efficient data path that accelerates virtualization, database access, and scale-out server response under heavy parallel workloads.
2. Its strong sequential read performance shortens backup recovery, analytics scans, and large dataset loading, helping enterprise platforms move bulk data with less wait time.
3. The very high random read capability, paired with near-memory-class latency, enables ultra-fast transaction lookup and consistently responsive performance in OLTP, metadata, and cache-intensive applications.
4. The extreme write endurance makes it well suited for write-heavy enterprise workloads such as logging, journaling, and high-frequency database updates, where sustained reliability directly reduces replacement cycles and downtime risk.
5. Built on 3D XPoint media, the drive delivers far more deterministic responsiveness than conventional NAND SSDs, making it ideal for latency-sensitive infrastructure that cannot tolerate performance cliffs.
Reference capacities in the same product family: Lower capacity: 280 GB Higher capacity: 750 GB Capacity positioning analysis: At 375 GB, this model sits at the sweet spot of the family. Compared with the 280 GB option, it gives noticeably more headroom for OS images, logs, metadata, and workload growth, reducing the risk of early capacity pressure. Compared with the 750 GB version, it keeps acquisition cost and fleet-level budget under tighter control while delivering essentially the same enterprise-class sequential and random I/O behavior. In practice, 375 GB is a strong fit for a medium virtualization cluster, such as hosting boot and infrastructure volumes for about 40 to 60 mixed-use virtual machines.
Q: Is SSDPE21K375GAT suitable for a write-heavy database server?
A: Yes. SSDPE21K375GAT is well suited for write-intensive database workloads, thanks to its 30 DWPD endurance, 20,500 TBW rating, ultra-low 10 µs latency, and enterprise-class 3D XPoint media.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 30 DWPD, meaning it can sustain 30 full drive writes per day over its warranty term. For a 375 GB drive, that reflects extremely high endurance.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical in enterprise environments because it helps prevent in-flight data loss and metadata corruption during unexpected power interruptions or system crashes.
Q: What RAID level is recommended for this SSD?
A: The recommended RAID level depends on your priority. RAID 1 or RAID 10 is typically preferred for enterprise SSDs when balancing performance, redundancy, and fast recovery in database environments.
