ScaleFlux CSD5320 Gen5 7.68TB E3.S Enterprise SSD Review – Data Compression Creates an Enterprise SSD Superpower

TSSDR INTEL XEON ASUS PRO WS W790E-SAGE SE TEST BENCH

This Test Bench is PCIe 5.0 and runs on a script originally authored by Allyn Malventano and graciously provided for our use by Jon Coulter of Tweaktown. It analyses every aspect of enterprise SSD performance.  It runs on the Ubuntu Linux Distribution and tests include 128K read and write throughput with latencies, 4K and 8K read and write IOPS with latency, and 4K Mixed loads 70/30 and 50/50 IOPS with latency.  All testing is steady state and there are twenty charts in total for our final report.

In setting up this test bench, the motherboards BIOS was updated to the latest release and the ONLY modification to the BIOS is that we turned hyperthreading off. We do this specifically for single core CPU-intensive applications where the OS scheduler may incorrectly manage the threads, resulting in sub-standard performance.

Building a workstation such as this isn’t possible without some great sponsorship.  We would lke to thank Intel for sending along their Xeon W7-2595X 26-Core Workstation Processor, ASUS for their  Pro WS W790E-SAGE SE Gen5 Workstation motherboard, Corsair for providing their W5 DDR5 ECC RDIM 64GB DDR5 DRAM 6000MT/s CL40 Memory Kit, along with their HX1200i High Performance Platinum ATX Power Supply, and Silverstone for sponsoring our build with their XE360-4677 HP Triple 120mm All-In-One Cooler for Intel LGA4677.

TSSDR TEST REGIMEN

Testing at The SSD Review strictly adheres to industry accepted enterprise solid state storage testing procedures.  All testing conducted follows and repeats the following pattern:

1. 1.  Secure Erase SSD
   2. Write the full SSD twice with 128K sequential data
   3. Precondition the SSD by filling its volume with 4/8K random writes twice.
   4. Run each workload with a 30-second ramp for five minutes at each Queue Depth.

BENCHMARKS SEQUENTIAL

128K SEQUENTIAL WRITE/READ

We precondition our enterprise SSDs using 100% sequential 128K writes at QD256 using one thread for two drive fills. Performance data is recorded every second.  We track this data to monitor the enterprise SSDs transition to steady-state and to verify that steady-state conditions are achieved before initiating queue depth testing. Steady-state is established after a full drive fill.

At this point, the average steady-state 128K sequential write performance is approximately 9GB/s while uncompressed but jumps to an incredible 13GB/s from QD8 to QD128 when 2:1 compression is in place.

The Scaleflux CSD 5320 has a listed 11GB/s write throughput which jumps to 13GB/s when 2:1 data compression is in place and our testing validates such.

Our test resulted in a high and average of 14.7GB/s read throughput while 2:1 data compression was in place which is our highest result to date. Full performance is achieved at QD32 where the performance  results in a perfectly flat line until the test was complete. This is very nice to see with 14.6GB/s being pretty much the dead on speed through QDs 16, 32, 64, 128, 256, 512 and 1024.  The uncompressed result was slightly less at 13.2GB/s.
