Teamgroup T-Force Cardea Zero Z440 1TB SSD Review (PCIe Gen 4)

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems 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 manufacturers 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.

We are using version 3.5 for our NVMe disk tests but have recently started to use ATTO 4 for testing so we've included results from these tests.

The official Sequential read/write performance figures for the drive are up 5,000 MB/s and 4,400MB/s respectively. Using the ATTO 3.5 benchmark the reviewed drive produced a read figure of 5,581MB/s, sailing past that official figure. The write figure on the other hand at 4,227MB/s was a fair bit off the stated maximum.

 
It was a similar story with ATTO 4.0 with the read performance bettering the official figure at 5,220MB/s while the writes were way off at 3,990MB/s.
