Benefits
Power Efficiency
Even at peak write performance, these E1.S SSDs consume 1/3 less power compared to standard E1.S with the same level of performance. In server systems where performance per Watt is crucial, this can significantly lower the power footprint.
Enterprise-Level QoS and Performance
Montreal drives feature QD1 latency of 89 µs that will ensure that your drive is able to keep up with the high-performance processors in servers and datacenters. They have continuous Sequential Read and Write speeds of 3455MB/s and 1321MB/s for the 960GB E1.S SSD, as well as 4K Random Read and Write IOPS of 674K and 329K.
Security and Data Protection
Montreal features end-to-end data protection and SECDED on all memories. It also has the latest security features with TCG SED/Opal, providing confidence for use in any environment.
Endurance and PLP
Featuring up to 1 DWPD using eTLC NAND, Montreal SDDs can also be configured for higher DWPD upon request. Additionally, PLP is a standard feature in enterprise-grade drives like these.
