We are just getting used to PCIe Gen 4 SSDs and now PCIe Gen 5 have been trickling out onto the market. For that Crucial has changed up their usual naming which was all focused around their P lineup with the P5 Plus being their highest-end drive. For the new drive, however, they have changed things up to T700 to indicate the new Gen 5 drive. With the specs highlighting rear speeds of up to 12,400 MB/s and write speeds of 11,800 MB/s we are in for another huge performance increase over what we saw with PCIe Gen 4 and especially Gen 3. So today I’m going to dive in and check out the Crucial T700 Pro with and without its heatsink to see what is behind the curtain and then check out their performance including comparing what the cooling can do for you. So let’s dive in!
