Crucial T705 Pricing and Warranty

Backed by a 3-year warranty, the Crucial T705 costs $240 to $730, depending on the capacity and heatsink. Here’s a full pricing rundown:

Crucial T705 SSD Performance

For this review, we will be looking at the 2 TB model while comparing it to the following SSDs:

• Samsung 990 PRO (2TB) (Gen4)
• ADATA Legend 970 (2TB)
• Corsair MP700 Pro (2TB)
• Seagate FireCuda 540 (2TB)
• Gigabyte Aorus 12000 (1TB)
• Solidigm P44 Pro (2TB)

For testing, we use two platforms. The consumer test platform supports PCIe Gen4/Gen5 SSDs. It is sometimes leveraged for lighter consumer-based tests such as BlackMagic DiskSpeed Test, CrystalDiskMark, and our primary platform, a Dell PowerEdge R760, which overlaps our enterprise tests. Serial Cables supplied an 8-bay PCIe Gen5 JBOF for testing for U.2/U.3, M.2, and E1.S/E3.S drives. This allows us to test all current and emerging drive types on the same test hardware.

Dell PowerEdge R760 Configuration

• Dual Intel Xeon Gold 6430 (32 cores/64 threads, 1.9GHz base)
• 1TB DDR5 RAM
• Ubuntu 22.04

VDBench Workload Analysis

When benchmarking storage devices, application testing is best, and synthetic testing is second. While not a perfect representation of actual workloads, synthetic tests help baseline storage devices with a repeatability factor that makes it easy to compare competing solutions. These workloads offer a range of testing profiles ranging from “four corners” tests and common database transfer size tests to trace captures from different VDI environments.

These tests leverage the common vdBench workload generator, with a scripting engine to automate and capture results over a large compute testing cluster. This allows us to repeat the same workloads across various storage devices, including flash arrays and individual storage devices. Our testing process for these benchmarks fills the entire drive surface with data, then partitions a drive section equal to one percent of the drive capacity to simulate how the drive might respond to application workloads. This differs from full entropy tests, which use 100 percent of the drive and take them to a steady state. As a result, these figures will reflect higher-sustained write speeds.

Profiles:

• 4K Random Read: 100% Read, 128 threads, 0-120% iorate
• 4K Random Write: 100% Write, 64 threads, 0-120% iorate
• 64K Sequential Read: 100% Read, 16 threads, 0-120% iorate
• 64K Sequential Write: 100% Write, 8 threads, 0-120% iorate
• VDI Profiles

Starting with 4K random read, the Crucial T705 hit a solid 1.02 million IOPS at 124.7ms for second place and just behind the Solidigm P44 Pro.

4K random writes told a somewhat different story, with the new Crucial drive at 256K IOPS at 72.5ms in latency. The best-performing drive here was the Samsung 990 Pro by a significant margin.

When switching to the sequential read 64K workload, the Crucial T705 took the lead by a significant margin, hitting 9.86GB/s (158K IOPS) at 202.8ms. The next best drive was the Corsair, which could only hit 8GB/s.

The Crucial T705 fell back a few spots in sequential writes, hitting a max of 18K IOPS at 855.2ms for 5^th place. Again, nothing could come close to the Samsung 990 PRO regarding write performance.

Next, we looked at our VDI benchmarks, designed to tax the drives further. These tests include Boot, Initial Login, and Monday Login. Starting with boot, the Crucial T705 was back in first place with 236K IOPS at 143ms.

Next up is VDI Initial Login. Here, the results are difficult to see in the chart; however, the source files tell us that Crucial T705 was 3^rd last with a peak of 50K IOPS at 603.3ms.

Finally, we have the VDI Monday Login benchmark, concluding the test at 48K IOPS with a latency of 333.6ms for 3^rd among the tested client-grade SSDs.

Crucial T705 BootBench

BOOT-BENCH-1 is a workload profile adopted by OCP to profile SSDs designed for server boot duty. While this is intuitively a job for enterprise SSDs, client SSDs are often selected for their performance, capacity, and cost combination. The boot drive issue is germane to hyperscalers and server and storage system providers, as they face similar challenges.

This boot workload executes an intense test plan that fills the entire drive with writes before testing a read-heavy workload sequence. For each test, it performs a 32K random read async operation alongside a 15MiB/s synchronous 128k random write and a 5MiB/s synchronous 128k random write/trim background workload. The script starts with the random-read activity at a 4-job level and scales up to 256 jobs at its peak. The final result is the read-operations performed during its peak run.

The OCP goal for this benchmark is a pass/fail at 60K read IOPS. Most drives we test will far exceed the minimum, but the results are instructive regardless.

The Crucial T705 SSD achieved an impressive 302,496 IOPS during the test, surpassing the OCP goal for this benchmark. This makes it the first Phison Gen5 SSD to pass (with very competitive results), making it a compelling choice for server and storage system providers seeking high-performance, reliable SSD solutions.

Crucial T705 CrystalDiskMark Speed Test

We performed a lighter-weight test on the Crucial T705 to demonstrate another metric of its speeds. CrystalDiskMark’s higher queue depth (compared to BlackMagic) allows us to showcase the best-case scenario for the drive. Any real-world performance differences would likely be negligible.

Here, the Crucial T705 performed very well in reads with 14GB/s in reads, with writes hitting around 4GB/s.

Crucial T705 BlackMagic DiskSpeed Test

Lastly, we measured performance inside a Windows 11 environment on our consumer test platform via the popular Blackmagic test. The new Crucial T705 hit a solid 9.82GB/s read, and 8.67GB/s write.
