    A Fast and Reliable 525GB Crucial SSD...
    I replaced an older Western Digital 500GB HDD with this new Crucial 535GB SSD in my son's computer as a performance upgrade. Installation was easy using a SSD bracket. I performed a clone data transfer, set the ACHI and Trim to SSD settings among other tweaks, and it's running great... only seconds in booting to the desktop. My son says he's getting fast and reliable performance from all his apps and games... excellent write and retrieval times beating the older HDD handily. It's only been installed for a couple of weeks now, so longevity is still to be determined. Thus far though, there is nothing to complain about.

    first SSD, impressed!
    havent had it long so i cant comment on life span or anything but from what little ive researched SSDs arent supposed to fail often like traditional hard drives.

    my first SSD, and the boot up is heaven. its literally like 2 seconds. i couldnt believe it. i hit the power button and looked at the TV for about 5 seconds turned around and it was on and was like well... next boot up i watched and wow...

    i bought it for reliability. that and the fast boot up alone make it worth it 100%. i havent really installed anything or done anything to test the speeds or see if i notice a difference

    Great drive!
    Excellent drive. Change up was effortless. Switch was less than 15 minutes. Longer to get computer open. Computer significantly faster. Partly with new op system but mostly faster drive.

    In June 2017 I put this in an early 2008 MBP and it breathed new life into an old machine. No commentary on reliability, nor performance comparisons against other SSDs, but it beats the spinning disk that came in the machine by an impressive amount... and the price is right.

    Fantastic Upgrade
    My stock PC laptop (Asus X541) laptop is a nice, budget machine that takes over a minute and a half to boot up and another few minutes to launch an app. Replacing the stock HD (5,400 rpm 1 TB drive) with the Crucial SSD has reduced the boot up and launch times to a minute or so. I bought a Crucial SSD because of the good reviews and the decent price. After a month of everyday use, I have no issues to report.

    While this is a no-brainer upgrade where you appreciate the benefits everyday, it's not a quick and easy procedure.

    If you are buying this (or any SSD) drive to upgrade a laptop, be prepared to spend time to backup/copy your data and have the tools and instructions on how to open up and replace your internal drive.

    Outstanding SSD
    Used this to replace the 500GB HD in a Toshiba Laptop with a 3rd Gen I5 processor and am delighted with the result.. Start up, application loading, file down loading and web page access are all lots faster than the 5200RPM SATA drive it replaced..
    Had a friend who's an IT pro do the cloning so I can't speak to that.

    I've had great experience with Crucial products and customer service in the past and this SSD continues the streak.

    I have recommended this to a friend

    a new lease on life
    My old PC was dying the death of 1000 cuts. Slower each day. Then, a new SSD! Everything is fast. Zoom. Happy. No need to replace the whole stinkin' computer.

    Installing in a mac mini 2011 was a little tough when making a HD copy and reinstalling the last grille, but it works fine now I need more RAM.
