Review: Works well in 2009 MacBook Pro - Installed in a 2009 MacBook Pro, cloned over the old drive with carbon copy cloner (free trial), swapped it out and booted up. So far so good, read speeds 296, write speeds 202 mb, boot up time 20 sec with Mac OS X 10.10 El Capitan. It's ok, not terribly fast, but my laptop is still stuck with SATA2 speeds. Of note, the package is bare with zero documentation, just the drive in plastic sleeve haha that's it. So if you need a little hand holding, this is not for you, probably because it's marketed to businesses.
Review: Speedy and Silent Performance - Hard drives are like silent partners; you don't usually appreciate them until they're gone or they flake out on you, and so they don't get the usual ecstatic "this changed my life" kind of praise that other components such as video cards get. I'm not about to rectify that imbalance with this review, but I am quite pleased with SanDisk's 256 Gb 2.5 SSD. I received a MacBook Pro recently and knew that the second or third thing I would do was swap out the 5400 hard drive for an SSD. I went searching around the interwebz, and found that desertcart had the best price. The SSD arrived quickly and installation was a breeze. With the OS installed and TRIM turned on, the MBP has been a joy to use. It's completely quiet, fast, and has generated no problems whatsoever. If you're looking for read/write speeds and a comparison of this SSD vs. others in the Samsung line or other SSDs, sorry -- I don't have other SSDs around to do that. However, a rather well-known fix/repair/upgrade site recommends this family of drives. It does what I wanted it to and after weeks of light-to-moderate usage and no problems, it's fully deserving of five stars.

### ⭐ HEED MY WARNING: DON'T DO IT!
*by J***H on June 3, 2017*

I've had an X300 drive for a little over a year now and it just went kaput, dead, silent, useless....yup, I lost the data contained therein :( Luckily for me I also have a Samsung SSD that I got around the same time and I had my OS on my Samsung as well as a backup on my 4TB HDD so I didn't lose windows or my absolutely critical files but all of my save games and some of my documents are long gone. Spend the couple extra dollars to get a better drive than this POS...OR...make sure you've got a secondary which you're backing the data up to on a regular basis (which kinda defeats the purpose of having the drive.
