SN740 SDDQNQD-1T00-1014

The Western Digital SN740 SDDQNQD-1T00-1014 is an affordable 1 TB PCIe 4 x4 NVMe SSD with a claimed sequential read rate of up to 5,150 MB/s and a claimed write rate of up to 4,900 MB/s. It is powered by SanDisk's 20-82-10082-A1 controller and a single high-density 3D NAND chip.

While the version we tested in Q3 2024 was a 2280 SSD, smaller 2242 and 2230 variants exist as well. At 400, the TBW value for the 1 TB model is nothing to write home about.

Performance

CrystalDiskMark 6 confirms Western Digital's performance claims while AS SSD 1.9 does not (we got just 4.47 GB/s and 2.26 GB/s for sequential reads and writes, respectively). Either way, these numbers represent a decent improvement over the 512 GB version and are absolutely sufficient for the vast majority of tasks in late 2024.

Power consumption

The drive normally consumes around 5 W under load according to the official spec sheet.

Acer Aspire 17 2024 laptop review: Weak dGPU and a disappointing display

Acer Aspire 17 2024 laptop review: Weak dGPU and a disappointing display

These days, dedicated entry-level and mid-range graphics cards are being increasingly pushed aside by integrated chips. We carried out a practical test and pitted the Acer Aspire 17's Nvidia GeForce RTX 2050 against current iGPU models from Intel and AMD.

Acer Aspire 16 2024 review: Multimedia all-rounder without a multimedia-worthy screen

Priced at €899, the 2024 Aspire 16 A16-51GM-77G2 pairs the low-power, current-gen Core 7 150U with the ageing RTX 2050. The laptop is meant to be a budget all-round multimedia laptop. In this review, we’ll discuss whether Acer manages to accomplish this goal.
