HPE SATA Very Read Optimized Solid State Drives deliver up to 175x faster performance, 4x lower latencies, and 3x better energy efficiency than 10K HDDs at a comparable price1. Designed for very read optimized workloads – vSAN capacity tiers, NoSQL databases, business intelligence, Hadoop, analytics, object stores, content delivery, and AI and machine learning data lakes.
Very Read Optimized is an HPE term used for QLC NAND based SSDs that have variable endurance levels or DWPD (Drive Writes Per Day) depending on how a customer writes data to them. QLC NAND requires the workload write percentage and block size be understood as endurance can differ from other SSDs. VRO SSDs are used for workloads that drive a typical mix of >80% random reads and <20% sequential large block writes. It is standard for all SSDs to use a 100% 4K random write workload to generate the specified DWPD listed in technical specifications. As VRO SSDs are not targeted at that 100% 4K random write workload, it’s important to consider the actual targeted workload. VRO workloads typically have all write operations that are sequential and in 128K blocks which allow all VRO capacities to support 0.8 DWPD. If used differently, the DWPD will vary based upon how the drive is written to. If used incorrectly, the DWPD drops to: 0.2 on 1.92TB; 0.09 on 3.84TB and 0.05 on 7.68TB VRO SSDs.
HPE Solid State Drives and Add-In Cards have a standard 3/0/0 warranty; Customer Self Repair (CSR) subject to maximum usage limitations. Maximum usage limit is the maximum amount of data that can be written to the drive. Drives that have reached this limit will not be eligible for warranty coverage.
