SERVER PROFILES
While synthetic workloads do a great job of testing the underlying technology and reporting easy to understand results, they aren’t always indicative of how the drive will be used by the end user. Workloads that simulate enterprise environments try to bridge that gap without being overly complex.
The database profile is 8K transfers, and 67% percent of operations are reads.
For our database profile, the Optimus Eco trails the Intel S3700 at higher queue depths.
The fileserver profile is based on an 80% read/20% write mix. Its made up of blocksizes from 512 to 64K, each making up a different percentage of the access pattern.
The pattern is: 512 bytes=10%, 1k=5%,2k=5%, 4k=60%, 8k=2%, 16k=4%, 32k=4%, 64k=10%.
The Optimus Eco gets the wire-to-wire win for our fileserver profile. At higher queue depths, the Optimus Eco pulls away from its competitors.
The webserver profile is similar to the fileserver profile, but has some additional 128K and 512K accesses thrown in for good measure. Additionally, the profile is 100% read.
We got nearly identical results with our webserver profile. While the Intel S3700 outperformed the Eco at low queue depths, the Eco once again pulled away with sufficient outstanding IOs.
FINAL THOUGHTS
Over the past year, we have reviewed multiple SMART SSDs and they have all performed extremely well. With the Optimus Eco, SanDisk has kept that tradition going. The Optimus Eco delivered excellent sequential and random performance, exceeding 500MB/s and 90K IOPS, respectively. We also observed excellent performance consistency.
Although SanDisk is positioning the Optimus Eco for read-intensive applications, the Optimus Eco has great write endurance. While it can’t match the 10 drive writes per day that the SMART Optimus and Intel S3700 provides, 3-7 DWPD allows it fit in fine in mixed workload applications. It continues to amaze us what SanDisk is able to accomplish with their FlashGuard technology. Just in case you forgot, the Optimus Eco is available with 2TB of storage. That accomplishment impressed us as much as the performance. In all, the SanDisk Optimus Eco is the total package.
