We use a lightweight virtualized Squốc lộ Server instance to appropriately represent what an application developer would use on a local workstation. The demo is similar to lớn what we run on storage arrays and enterprise drives, just scaled baông xã lớn be a better approximation for behaviors employed by the kết thúc user. The workload employs the current draft of the Transaction Processing Performance Council’s Benchmark C (TPC-C), an online transaction processing benchmark that simulates the activities found in complex application environments.

The lightweight SQL Server VM is configured with three vDisks: 100GB volume for boot, a 350GB volume for the database and log files, and a 150GB volume used for the database backup we recover after each run. From a system resource perspective, we configure each VM with 16 vCPUs, 32GB of DRAM and leverage the LSI Logic SAS SCSI controller. This demo uses SQL Server năm trước running on Windows Server 2012 R2 guest VMs & is stressed by Dell’s Benchmark Factory for Databases.

When looking at SQL Server đầu ra, the SX6000 drive landed at the bottom of the paông chồng of drives with a score of 2,103.2 TPS, well below the other drives.

For average latency of the same demo, the SX6000 drive hit 2,386ms, massively above sầu the other drives for last place.

VDBench Workload Analysis

The peak 4K read performance of the SX6000 drive was last with a peak score of 93,970 IOPS at a latency of 1.36ms though the drive did have sub-millisecond latency until about 85K IOPS.

*

With 4K write the SX6000 again came in last with a peak performance of about 19.7K IOPS & a latency of 5ms before dropping off in performance and shooting up in latency.

*

Switching over to lớn sequential workloads, in 64K read the SX6000 trailed the rest of the paông chồng. The drive sầu stayed under 1ms until about 10K IOPS or 600MB/s & peaked at 10,790 IOPS or 674MB/s at a latency of 1.48ms.

For 64K write the drive sầu remained in last with a peak performance of 3,753 IOPS or 234MB/s at a latency of 4.25ms.

*

Next, we looked at our VDI benchmarks, which are designed to lớn tax the drives even further. These tests include Boot, Initial Login, and Monday Login. Looking at the Boot chạy thử, the SX6000 stayed in the bottom of the paông xã with a peak performance of about 43K IOPS and a latency of 792ms before dropping off some & latency going up. This was the first time that the SX6000 stayed under 1ms throughout.

*

With VDI Initial Login the SX6000 was again last seeing a massive latency spike before dropping off to lớn a peak performance of 8,625 IOPS at 2.12ms latency.

*

Finally, with VDI Monday Login, the SX6000 stayed in last place và peaked at 9,805 IOPS with a latency of 1.63ms.

*

Conclusion

The ADATA XPG SX6000 is an M.2 PCIe SSD aimed at being a performance nâng cấp from older SATA SSDs. The drive has quoted speeds of 1GB/s read and 800MB/s write and it offers both SLC Caching và DRAM Cađậy Buffer khổng lồ help optimize performance. The SX6000 comes in capacities as high as 1TB and comes with a 5-year warranty.

Looking at performance the drive didn’t vị so well in our benchmarks. In our Houdini chạy thử the drive sầu came in the bottom third with 3,556.5 seconds. From here on, the drive sầu always came in last place. In our Squốc lộ Server the drive sầu had a very low 2,103.2 TPS và an incredibly high latency of 2,386ms. In our VDBench the drive didn’t fare much better with peak performances of 94K IOPS for 4K read, 19.7K IOPS for 4K write, 674MB/s for 64K read, & for 64K write the drive hit 234MB/s. The drive did not maintain sub-millisecond latency in any of the above sầu tests. In our VDI Boot the drive did stay under 1ms but was in last with about 43K IOPS. In VDI Initial Login và VDI Monday Login, the drive sầu his 8,625 IOPS & 9,805 IOPS respectively.

Overall, the ADATA XPG SX6000 is not a very high-performance drive sầu, despite the specs. As an upgrade from an old SATA SSD or hard drive, or if cost is a limiting factor, then the SX6000 is probably fine. If one is after a better performance profile though, there are several better options available.
