You should and will need a compatible heatsink for this drive, regardless of what youtubers or others say. If you wish to extend the life of this device it is paramount to get one. I bought this one: https://www.amazon.com/gp/product/B07KDDKDNN/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 for $17.99 and it is an EXCELLENT fit and I mean PERFECT. Super easy to apply and install and takes less than 5 mins. Even comes with a screwdriver that can be used to also unscrew the ssd compartment on the console, one tool for the job!As far as this drive goes, once installed it registered at 6532.91 MB/s which is significantly faster than the internal SSD. I transferred 5 games totaling about 200gb in under 5 mins to this ssd from the internal storage. Afterwards, I proceeded to download some games from the PS Plus collection and several others from previous free PSN games. That obviously took some time but after finishing I now have about 13 games at 900GB and still have 1.3 TB of space available. Unlike with traditional or hybrid HDDs you get the FULL ADVERTISED SPACE. Not 1.97 TB or 1.8 TB, 2 TB which can be used immediately upon rebooting your console.Booting up Farcry 6 with the disk from the home screen to the saved game position took about 25 secs give or take a couple for me to move the cursor to Continue Game. I have had no game crashes as of yet and no issues with pop in or textures or assets missing other than what the game shipped with. No slow downs and load times from death screen are about the same as internal storage which is approx 6 secs. Don't expect to load large open world games like that any faster than internal storage unless made by first party studios. Primarily, this drive is to allow you more space for your current collection. I have 37 games, 9 of which are PS5 games and in theory I could install my entire library between the internal and M.2 storage.Tips: Make sure you either take a picture of your drive before you install the heatsink or write down the serial number as it is not on the box so you can register it at Wester Digital for your warranty. I did not do it and would have to remove the card, remove the heatsink and get the product serial number then reassemble and reinstall (dammit bobby!). Warranty is 5 years which is better than spinning drives which tends to be about 3.The Samsung 980 is the comparable drive releasing end of this month for $449.99 and the only main difference is the price and convenience of plug and play, no additional heatsink purchase necessary. However, if you want to save $110.99 buy this drive and the heatsink I linked and you save bigtime, using the extra money for your next game!Should you later decide to get a larger 3 or 4 TB SSD you can take this one and add it to your PC. Or if we get a PS5 with a 2TB SSD built in then add this drive to that console and double your storage capacity which would be more than enough until the next console cycle. I really hope this review helps others specifically buying for their consoles. I cannot speak to the performance on PC at this time. Game on Comrades!
