    • Reliable and Affordable – The Perfect Storage Upgrade for Daily Use
Capacity: 1TB Style: 2.5"/7mm SSD
The WD Green 1TB SSD is an excellent choice for anyone looking to breathe new life into an older laptop or build a budget-friendly PC. Here is my practical take: * Performance: While it’s not designed for high-end video editing or professional gaming, it is incredibly fast for everyday tasks. Boot times are under 10 seconds, and apps like Chrome or Office load almost instantly. * Reliability: WD is a trusted name in storage. I’ve found this drive to be very stable. It runs cool and quiet, which is a massive upgrade over a traditional mechanical hard drive. * Power Efficiency: One of the best features of the "Green" line is its low power consumption. I noticed a slight improvement in my laptop's battery life after swapping my old HDD for this SSD. * Value: Getting 1TB of solid-state storage at this price point is a steal. It’s the perfect "set it and forget it" drive for general home or office use. Verdict: If you need a reliable, high-capacity drive for daily computing without overspending on "Pro" features you won't use, the WD Green is a no-brainer. It’s simple, efficient, and effective. ... show more

    • Reliable drive! Great for raspberry pi devices
Capacity: 120GB Style: 2.5"/7mm SSD
Very reliable compared to some other brands that I have tried. I use these smaller capacity drives for raspberry Pi devices. Using an SSD drive increases speeds on the Pi significantly compared to running off SDCard.

    • Saved my HP laptop and booted on the first try after cloning.
Capacity: 1TB Style: 2.5"/7mm SSD
I have a HP laptop I purchased from Costco in '22 and it had a HDD and never really worked right. It finally got so slow that I was ready to get another one. But when I looked at the performance the HDD was always right at 100% no matter what so I thought that despite the properites saying it working correctly, maybe it's the hard drive. I pruchased this one and a inexpensive SATA cable and used Acronis to clone the drive which took over two hours. Once that was done I swapped the old internal HD for this one and it fired up on the first boot in seconds. Now it's like a new PC shuts down and loads in seconds rather than minutes. I'm doing any gaming or anything but all I can say is this disk saved me from buying a new PC. Very happy with it and it's performance. It loads programs and apps extremely quickly. ... show more

    • Ok for price but filthy!!!!!
Capacity: 480GB Style: M.2 2280 SSD
Received for Amazon warehouse in used condition. The hard drive does run well as Western Digital makes good drives. The drive I received was filthy and had what appeared to be a substance like soda spilled in the package and all over the drive. I had to clean the drive before I could use it. Was described as like new condition. ... show more

    • Value, Delivery and easy install
Capacity: 2tb Style: 2.5"/7mm SSD
Trusted Brand (Western Digital), Reasonable price, Next Day Delivery - All added stars to my rating. Reasonably easy install - The tough part of the install was removing the failing HDD, and getting the computer out from under my desk just to work on it, and removing all the wiring, including the power cord. After identifying the failing HDD, removing the cable connections to it, and removing it from the bay, installation of the new SDD was easy. The trickiest part was starting the screws to hold it into the Drive Bay. Connected the old cables and done! Reconnected all the wiring, slid the computer back under the desk, turned the power back on and booted the computer. Windows 11 OS detected the missing HDD and the new SDD, and automatically initialized the new one. Used the Disk Manager to assign Drive letter and name to the new drive and format (just took seconds). I am really pleased this install went so smoothly - couldn't be happier! FIVE STARS! ... show more

    • Good value for 2TB in this day and age.
Capacity: 2tb Style: 2.5"/7mm SSD
It's a nice drive. Being the "Green" version, it's a bit slower than others but not that I can tell. I bought this for media storage like movies and music and it works great. With the prices of RAM and SSDs going through the roof, this was a decent price.
