I have had some problems with my laptop recently, and I wanted to change the current hard disk drive. On task manager, the hard disk drive is labelled as ST1000LX015-1U7172. From Googling, I understand that this is a 2.5 inch SATA Internal SSHD Hard Drive with 7 mm Form Factor. I am looking to replace this with an SSD.

I was worried about compatibility, and I just wanted to ask for advice on here as to whether what these SSDs may fit in place of the current HDD, and if you have any recommendations.

My laptop is a ROG Strix G531GU for context. Thank you!

  • Crucial is also a rock solid reliable brand FWIW. I don't agree that "anything" Samsung puts out is a good choice; They have had some bad firmware issues over the years that led to customers losing data. Do your research for stuff like this when you've narrowed it down to a model number. You might even find this is true for Crucial too but I personally can't recall any wide-spread issues on their SSDs.

That Crucial and Samsung SSD are fine, although I personally have preference on the Crucial MX500. Here in Belgium it's pretty cheap, it will fit on any spot where there used to be a SATA HDD, and is availible in capacities between 250GB and 4TB. It also has a DRAM cache which makes it so things slow down less under heavy load. Although the price has increased lately, it's still an okay price since it's high quality (€80 for the 1TB model)
