Should you remove an SSD sticker before mounting a heatsink?

Measurement results

Here are some questions that everyone who wants to tune their computer to the last detail deals with: Does it make any sense to remove the sticker from a powerful M.2 SSD format? Is it worth the effort and, if something goes wrong, the breach of warranty? How much will the heating be reduced? As a part of detailed tests, we also exchanged the original stickers for ones of commonly available materials (paper, plastic foil, aluminum…) just out of curiosity. Do SSD manufacturers use anything extra?

Best case scenario, the SSD without a sticker. The most intensive heating of the heatsink means the most efficient heat absorption
Worst case scenario, the SSD with a 300g paper filler. The least intensive heating of the heatsink means the worst efficiency in heat absorption

SSDs more reliable than HDDs? Study shows similar failure rate

In May, we had reported on a study by Backblaze, which publishes statistics on the failure rate of hard drives operated by its service. Backblaze also started reporting failure statistics for the SSDs it uses as system drives and the results at first seemed to be orders of magnitude better. But their new data now shows a picture much less promising, it looks like SSD fatality rates might not eventually be so different from HDDs. Read more “SSDs more reliable than HDDs?

SanDisk Extreme Pro Portable SSD V2: bigger and faster

We have already tested external SSDs from SanDisk several times. However, it has always been a model of Extreme Portable SSD, namely from 2018 and 2020. However, the manufacturer also offers another model, which it refers to as Extreme Pro Portable SSD. We have tested its second generation from 2020 in detail and we will be interested in whether it’s worth paying extra for the “Pro” label or whether you can do with the base model.

The first PCIe 5.0 ×4 SSD controller, speed up to 14 GB/s

It looks like PCI Express 5.0 SSDs will roll out at slower pace than PCI Express 4.0 ones, but the first controller to use this technology is already coming. Marvell has now unveiled the Bravera SC5 chips, which are to power NVMe modules with read speeds of up to 14 GB/s and 2 million IOPS. To handle this, the chips have ten different ARM cores inside. These SSDs will likely only target servers for now though, not desktops or laptops yet. Read more “The first PCIe 5.0 ×4 SSD controller, speed up to 14 GB/s” »

  1. Having spent a lot of time building and repairing high power solid state RF amplifiers I have a few recommendations: to get the maximum heat transfer it is essential to get good contract between chip and heat-sink so no stickers, no heat conducting pads just a thin spread of good thermal paste between the controller chip and the heat-sink you can apply a thermal pad to the non component side for stability. The controller chip is the only component on the board generating heat, the memory chips don’t so you are effectively heating the memory chips buy placing thermal pads over them and attaching them to the heat-sink!

  2. Finally a good article, that makes sense and shows the tests about this issue.
    Now all is clear and thank you for publishing this.

  3. Can you also test combination no sticker + thermal paste + heatsink?
    I have removed the sticker, put ton of thermal paste on SSD and attached lapped cooper heatsink (6mm thick).
    But now I’m little aftraid that cooper surface may cause conductivity between SMD components and cause short circuit.
    So the original sticker may also serve as electric isolation layer.
