5but I am in IT and I buy these because they are a good value, and reliable
By Nick R.
Samsung gets all the press nowadays because their SSD's are the highest performing... but I am in IT and I buy these because they are a good value, and reliable. The Crucial/Micron brand SSD's have been made in the same factory, and they both offer rudimentary power protection. This doesn't protect writes that were being made when you lost power, but it does offer some protection on the rest of the data. Other brands without power protection can suffer major file system damage if power fails during use. I put these in OEM laptops (and MX200's before this one), where people run out of batteries, and I've yet to have a serious failures.

5Good hardware, poor software, used a different utility with no issues
By Tghu Verd
I swapped an old Hitachi TS7SAA500 hard drive in an ASUS i5 Windows 10 PRO laptop with the MX300. Did not do any performance stats but the SDD is definitely much quicker.

Firstly, backup your drive and create a recovery disk. It should not be a problem as you'll have the old drive in any event, but when you are playing with disk image software it pays to be extra careful.

Also buy or make sure you have either a USB to SATA cable (I bought the $12 StarTech USB 3.0 to 2.5" SATA III Hard Drive Adapter Cable w/ UASP - SATA to USB 3.0 Converter for SSD/HDD), or a spare slot in your PC to connect the MX300 or you will not be able to create a usable SSD drive.

With cable in hand I firstly had trouble downloading the US version of the Acronis True Image (ATI) software, as the browser download would stall around the 140MB mark and then fail with a timeout error. This happened on the two machines I tried, and it took repeated goes before the 200+ MB file loaded.

Then I found you have to create a Acronis login, which I did not want to do, esp. as I did not have internet connection on the PC. That's OK I thought, there is an "I don't have an Internet connection" option on the application start screen. That option takes you to a screen where you enter the drive serial number, but nothing actually happens. The only option is to revert to the page that requires you to login so that was frustrating. I don't want to have a relationship with Acronis, just use their app once to image my SSD.

Eventually I gave up and used Partition Wizard's free MiniTool utility to copy my 500 GB HDD image to the MX300, which took a few hours on my USB 2.0 laptop. I also needed to delete the Acronis app because once installed - even if you've not used it - it is lurking in the background wanting to back files up.

Once that was complete I physically swapped the MX300 into the single drive bay in the laptop. It is a simple unscrew/connect/screw process that took less than ten minutes. After that, the laptop booted up off the SSD and I was straight into Windows 10.

Once the drive was installed I upgraded the MX300 firmware; even though it's a brand new drive, there is always a chance the firmware is out of date. That meant downloading the firmware from the Crucial site - which had no performance issues, unlike the Acronis site - and using the supplied ISO to create a bootable CDROM. Booting involved BIOS changes on the laptop to boot from the CD first, not the SSD, and the MX300 firmware update software looked like a Linux app when it ran, but it worked fine.

All of this took a few hours, but a lot of that was waiting for software to download, install or run. I have not yet done is wipe the Hitachi HDD, but that's a task for tomorrow. Now I am just enjoying my hugely faster laptop which has been given a new lease of life for $200.

By Jay
I bought the Crucial MX300 1TB SSD and I put it into the PS4 Pro.

Holy crap! This thing is amazing!

Highly recommended and suggested that you bite the bullet and invest in a proper SSD!
