In order to test the NVME drive we used the following configuration:

• CPU: AMD Ryzen 9 7950X
• Case: be quiet! Dark Base Pro 901
• Case fans: 2x140 be quiet! Silent Wings 4 PWM
• CPU Cooler: Noctua NH-U12A Chromax.Black + 2x120mm Stock Noctua fans
• Motherboard: Asus ProArt X670E-CREATOR WIFI with 1415 BIOS
• Memory: 2x16GB AddLink Spider X5 DDR5-6000MHz (EXPO Profile)
• PSU: be quiet! Dark Pro 13 1300Watt
• Main Storage: Samsung 980Pro 1TB
• VGA: MSI GeForce RTX 4090 SUPRIM X 24G
• Operating system: Windows 11 x64 + latest motherboard/AMD chipset drivers installed (DirectStorage enabled drive)

Since our motherboard supports TWO Gen5 drives, we had both of them installed. The Crucial T700 barebone edition was installed in the "second" Gen5 slot, under the big passive heatsink of the Asus motherboard. However despite that, we did notice high temperatures, and for that in order to perform our tests we had to install a small 40x40mm fan to blow air at this slot to avoid thermal throttling and reduce temperatures. Note that at least with the Asus ProArt X670E-Creator motherboard, big VGA cards, like the MSI 4090 are exactly above the passive heatsink, so you won't be able to use aftermarket heatsinks at both Gen5 slots.

The temperatures were much improved with the 40x40mm fan and we saw up to 68 Celsius when fully loaded the drive.

After the first format, you can expect around 1.81TB of empty storage

The latest version of CrystalDiskMark reports around 12.3GB/sec reading and 11.8GB/sec reading at sequential files.

The latest ATTO Disk Benchmark 4.01.0f1 version, we got very high results, up to 11.53GB/sec reading and 11.04GB/sec writing performance.

At the I/O Meter test, the Crucial T700 drive didn't show great performance even with the updated firmware, it got around 44449.93 points and showed a high I/O response, which was confirmed even after running three times the same test. Perhaps with Intel-based systems, performance could be better. For comparison, a Samsung 990Pro will take the same test around 155.000 points.

Windows 11 also includes a build (quick) transfer test, only with a 64kb file size

Then we tried to copy big files from the Crucial Τ700 2TB NVME SSD to the Crucial T700 2TB NVME SSD (barebone) drive, under Windows 11 either with the Windows Copy file function or with Terracopy software, which however didn't show great performance, as we would have expected. The reported transfer speed was around 3.7GB/sec, which was much lower than we expected from two very fast drives:

We tried several file copy software, and finally, we used the latest FastCopy software, which promises the fastest possible copy transfer speeds. First, we tried a single 44GB file size from Crucial T700 -> Crucial T700 drive and it was finished at 5.2sec, with an average write speed of 9.01GB/sec

Performing the same test with a single 218GB file, gave us even better results, with a reported average writing speed of 11.76GB/sec. While the evaluation version of FastCopy does work nicely, it isn't very practical for everyday use, maybe user functionality will further improve with newer versions.
