08-06-2025Didnt work in my lenovo laptop as this product demands higher amp: 5v 2.1A - which was making windows 10 OS freeze. I finally installed an Intel drive, 5v 1A, which works fine. I do not recommend this product as this may damage the notebook hardware.

> 3 day750GB is perfect. Wanted to go with an all SSD PC, so I could get rid of the 3.5 hard drive cage in my case. This is probably the best performance/capacity/cost ratio on a SSD. Sure, its not as fast as the 850 EVO/Pro drives, but those are a) more expensive and b) 500/512GB SSDs. That said, its insanely fast, and I would be hard pressed to tell the difference on real world usage between them. 3D NAND also comes with a very nice Endurance boost. If you want a SSD storage drive, I cant really think of a better option than this one. Cheaper ones can be found yes, but they also compromise on performance. This one hits the sweet spot.

Greater than one weekUsed this SSD to upgrade an iMac 7,1 and 9,1. Works great. Very fast compared to the HDD. Just need to use an adapter bracket to hold this SSD in the drive bay. I used the NewerTech AdaptaDrive 2.5 to 3.5 SATA adapter.

> 3 dayWith an SATA-to-USB 3.0 adapter, this works great as a portable USB drive. Its super-fast for back-ups and file transfers, and its so much smaller than a typical external USB drive. Eventually, this will make its way into a desktop system replacing a 3.5 7200rpm 500 GB hard-drive...from experience, I can anticipate huge performance improvements with an solid-state drive in that system.

> 3 dayFast and reliable. I bought it for my Mac Mini 2011 and now I have a brand new a nd fast computer. I should have done the upgrade way earlier.

09-06-2025Full disclosure: I am a sysadmin. More than capable of upgrading a drive, Ive done it hundreds if not thousands of times. I purchased this, my first SSD, with some trepidation about the lifespan of the number of potential write-cycles that I would be able to get from the drive before it wore itself out. Not something I have ever worried about with spinning platter drives. After installing and cloning my Macbooks main drive (I have two drives internal, and moved all the media / heavy data files to the other disk) yes, the computer booted up very fast. Id say the total boot time went from about a minute (I load a lot of programs) to about 20 seconds. Loading programs also was much snappier, they launched into memory (16gb) much quicker than before. So Im going about my day, using this like any other disk... Until I get a funny error message from Thunderbird (my email client) that it was unable to write to the cache when downloading mail. Odd... Close the program, try to relaunch - error that it is already running. Check Activity Monitor... Nope, nothing there. Launch Finder to go look if the lock file is stuck... Finder skyrockets to 180% processor use, and the system grinds to a crawl. Icons stop properly rendering (because they are also cached to disk), and eventually I have to hard-boot the system to get back to using it. Everything comes back up as it was several hours before, and works great again for several hours until... Lather, rinse, repeat. Crucial Tech Support suggested that the power management needed to be completely off for the drives, that the operating system cannot try to put the drive to sleep as that would cause problems. NOWHERE IN ANY DOCUMENTATION had I seen this, and still have not. So I disabled that, and all was well yesterday for about 5-6 hours of usage. Im somewhat dubious that a computer will just magically cut power to a drive without receiving any kind of acknowledgement from the drive that it is ready to power off - that isnt how power works, the computer can send a please power down command to the drive, but it is usually up to the drive itself to accept or reject this command. But this is what the tech at Crucial says happens: That the computer just cuts the power off when it wants to send a drive to sleep and this screws with the SSD since they have to always have full power. OK, so Ill try that for a while... It worked last night anyway and nothing interesting popped up in the system logs. Wake the computer this morning, and within 20 minutes of starting up, I find Disk I/O Error comments in the system log! Funny thing is, it took another 2 hours after those errors before the drive errors locked the system again. Again started with the error from Thunderbird (like a canary in the coal mine) and just so you dont think it was somehow Thunderbird - I have this program open all the time, and it checks for email about every 10 minutes, and I get about 150 emails a day. So if there will be a drive issue, this is the most active program to trap it. So this drive is now pulled, and being sent back - Thank you Amazon and your great return process. I havent decided yet whether I will try another SSD... But certainly not THIS brand, with no Mac-based tools OR support staff with any kind of clue of what is actually happening. I have NEVER had problems like this with my spinning drives, and the only thing on the computer that was different was the installation of this SSD... So the problem is definitely within this product. The speed is NOT worth the tradeoff of possibly losing your data.

Greater than one weekGot this drive to upgrade an Asus laptop that I recently purchased. I was migrating from an older Asus Laptop and I had also purchased a USB to SATA cable to image the drive. I found out that you cannot image the drive through a USB and have it bootable. Both machines were running Windows 10. I used Macrium Reflect free for doing a backup of my old drive to another external hard drive over USB. I then created a USB boot drive using the utility in Macrium Reflect (boot and recovery/restore tools)...set the BIOS in my new laptop to boot from the USB drive...installed the Crucial drive in my new laptop...booted using the USB drive...and then restored the three partitions from the backup (separate USB drive) to the new Crucial drive. I then used the utility to fix the boot sector (1st partition) then shut down the computer. I then crossed my fingers and rebooted...it booted normally and discovered the new hardware and installed the correct drivers. I found that you must have the SSD drive hooked up to a SATA interface and do a restore instead of cloning the old drive directly (I had tried this first without success). I hope this helps anyone looking to upgrade their laptop.

Greater than one weekFor my main desktop been waiting for a drive that made sense with a ~300GB Boot drive...This is the best deal from a reliable company for anything much bigger than 500GB...Mushkin 1TB is the only other option but that is kinda slow...MX300 is a winner. Hint make regular backups, (Paragon have a free version backup app available that will even move an OS drive to different hardware). Super drive got multiple sizes (275GB for the laptop)

Greater than one weekMy 2011 Mac Mini was running unbelievably slow. Im talking spinning wheel just trying to open a file on the desktop. Time machine wouldnt even do a backup and error codes would pop-up every time I tried to reinstall the OS. I took a leap and diagnosed my computer with a dying hard drive. I ordered the crucial and then installed it hoping it would fix my slow as molasses computer. HOLY CRAP. This SSD has solved every one of my issues. Boot up is extremely fast, and everything installed from my latest backup with no issues. Files and folders open instantaneously. It feels like a brand new Mac. Heck, it even feels faster than the new 2016 macs. How is this possible? I dont know and Im not going to question it. I just know Ill be buying Crucial Memory from here on out.

Greater than one weekI installed this SSD on my MacBook pro mid-2012, the speed of my mac is now relatively better but I didnt notice the extraordinary speed. I can see the difference when I open multiple apps and they open easily and quickly compare to non-SSD.
