Amazing 9/30/2020 9:29:31 PM

Pros: This SSD is easily as fast if not faster than all of my Samsung 850 Evos that i've worked with. I highly recommend this, Western Digital has been my go to for reliability and performance for a long time, this is actually the first WD SSD I've gotten, I believe they purchased Sandisk or has a partnership, I'm not sure which, but Sandisk always had the most reliable Flash drives that I had used which is solid memory also!.

Cons: doesn't come with SATA cable or software, BUT DOES HAVE CLONING SOFTWARE FOR OS DRIVE AVAILABLE ONLINE. Acronis western digital clone worked amazing for me, if you're getting a bigger drive simply expand with diskpart commands, google to use if you don't already know. This also doesn't come with an external enclosure or anything but its super light, just connect to mother board and power supply and let it hang until it's done, if you don't have 2.5" slots there are holders cheap on here. This is not TRULY a con because comparably by price, with this and cables and or an enclosure to swap drive, this is still cheaper than Samsung as of this moment for now. if you have M.2 check out Western Digital Black edition SSD.

Overall Review: This SSD is FAST, so far it is also reliable and easy to install.

Easy installation 9/30/2020 9:21:41 AM

Pros: I watched a YouTube video before installing the drive. I purchased a SATA to USB cable. I used Aomei Backupper to clone HDD to new WD SSD (did not need to format the SSD before cloning). It took about 4 hours to clone the 1 tb HDD to SSD. Opened up my Toshiba C-55 laptop and swapped out the drive. It fit perfectly. After reassembly, I restarted the computer. IT BOOTED UP VERY FAST with no problems.

Cons: None

Overall Review: I’m very pleased with my purchase and installation experience. I wished that I had done this awhile ago, however.

Overall Review: Speaks for itself. It's a SSD. Easy to install in my case, used it for my laptop to replace the 1 TB HDD it came with.

Does its job nicely for what it is.

Awesome drive! 9/30/2020 4:14:24 AM

Pros: Quick and reliable for a main drive.

Cons: None.

Overall Review: My mother's old hard drive from 2014 began dying so I bought this for her PC because my 1TB version has been amazing, too. She's super happy because now her programs run faster than ever before.

The only hiccup I found in the whole ordeal was caused by myself; as I used her old 1TB drive as a temporary storage location and because she likes to save to the desktop, I changed the save location of the desktop to the old 1TB, which caused a continuous error eventually leading the PC to reboot without warning; however, I have since undone this and all rebooting has stopped. (I only write this to say I did not put it in as a Con because the error was not caused by the drive itself but by Windows not liking the changes I did. And I only would've placed it as a Con and reported the errors if they persisted after troubleshooting.)

So far so good 9/29/2020 7:31:07 PM
