Sonnet Tempo AHCI PCIe AIC SSD Review (Page 4)

TweakTown Rating: 88%Manufacturer: Sonnet


Version and / or Patch Used: 2.47

ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.


Sequential read/write transfers max out well above Sonnet's listed sequential specifications, especially on the sequential read side of things. Keep in mind this is our OS volume, and it is filled to 75% of its total capacity. The Tempo ramps up fast. The highest sequential read performance is achieved at 256KB transfers. The highest sequential write performance is achieved at 512KB transfers.

Sequential Write


We decided to throw the Tempo into the fire and compare performance with today's fastest NVMe based SSDs. The Tempo hangs in there quite nicely even surpassing the sequential write performance of the 950 Pro. Toshiba's XG3 and RD400 deliver the best sequential write performance of the bunch.

Sequential Read


The Tempo delivers far superior performance in comparison to Intel's 750 Series NVMe SSDs at transfers of up to 512KB. Samsung's 950 Pro crushes the competition at transfers of up to 256KB.

Anvil Storage Utilities

Version and / or Patch Used: 1.1.0

Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test or just the read or write test, or you can run a single test, i.e. 4k QD16.




Anvil's scoring gives a good indication of a drive's overall performance. Regarding overall scoring, the Tempo delivers a nice score even though it is the lowest overall. This is to be expected from an AHCI-based SSD versus NVMe SSDs because the NVMe protocol inherently provides higher IOPS. If we focus on read performance, the Tempo easily outperforms Intel's 750 Series NVMe SSDs.

(Anvil) Read IOPS through Queue Depth Scale


If you look closely, the Tempo does outperform the Intel 750's up to QD8.

(Anvil) Write IOPS through Queue Scale


The Tempo is last across the board. However, it hangs in there with the 950 Pro at QD4 and beyond. This portion of the test falls into the 1.2TB Intel 750's wheelhouse, and it dominates from start to finish.
