Out of the box, the drive came formatted in ExFat, but to use our benchmarks to test the drive we reformatted it to NTFS.
CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using V8.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage system's performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturer's RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.
AS SSD is a great free tool designed just for benching Solid State Drives. It performs an array of sequential read and write tests, as well as random read and write tests with sequential access times over a portion of the drive. AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.
The official quoted transfer rates for the T7 Shield are reads up to 1,050MB/s and up to 1,000MB/s for writes. When tested with the ATTO benchmark the review drive fell a little short of both of these maximums, with a read result of 1,002MB/s and writes at 999MB/s. However using CrystalDiskMark default Sequential tests we got a read result of 1,094MB/s, 44MB/s faster than the official figure, while the write result came in at 1,051MB/s, again faster than the official figure.
