Reliable and High Performance for Read-Intensive Workloads

Edge Computing and operating system boot operations require high performance and reliable storage. Edge computing – content delivery (CDNs), online gaming content, IoT, data analytics – is heavy on data reads. Rapid operating systems boot performance is critical for public cloud services to quickly launch computing instances. Large-node compute clusters need rapid boot performance for boot times and rebooting.

Western Digital CL SN720 is a purpose-built NVMe M.2 form factor for the specific requirements of boot and edge workloads. Reliable read performance, power efficiency, data security standards support, and remote management ability are some of the key attributes.

Disclosures

1: Specifications below are base on 1TB capacity and vary by capacity. Contact Western Digital for further details. Product specifications subject to change without notice. Not all products are available in all regions of the world.
2: As used for storage coapacity, one gigabyte (GB) = one billion bytes and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environtment.
3: 2TB expected availability in early 2019.
4: Test Conditions: Sustained Performance is based on the FIO benchmark using a 1TB Western Digital CL SN720 NVMe SSD and a 10000MB LBA range ASUS Z170A desktop with Intel® i7-6700K 4.0GHz, 8GB 2133Mhz DDR4. Windows 10 64-bit using Microsoft StorNMVe driver, secondary drive. Performance may vary based on host device. 1 MB = 1,000,000 bytes. IOPS = input/output operations per second.
5: TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
6: Measured using MobileMark™ 2014 on HP EliteBook X360 1030 G2 with i7-7600U, 8GB RAM. Windows 10 Pro, 64-bit RS3 using Microsoft StorNVMe driver, primary drive.
7: Power measurements at 25oC.
8: MTTF = Mean Time To Failure based on internal testing and by using Telcordia stress part testing (Telecordia SR-332), GB, 40oC). MTTF is based on a sample population and is estimated by statistical measurements and acceleration algorithms. MTTF does not predict an individual drive's reliability and does not constitute a warranty.
9: Operational temperature as reported by device (composite temperature).
10: Non-operational storage temperature does not guarantee data retention.
11: 5 years or Max Endurance (TBW) limit, whichever occurs first. 5 year warranty in regions not recognizing "limited". See Western Digital Support
