SanDisk Extreme PRO 240GB SATA 6.0Gb/s 2.5-Inch 7mm Height Solid State Drive (SSD)

Been using in my primary computer for about 4 months now, works great so far. The real test is to see how long it will last before failing. A previous model lasted about 5 years. Im hoping this one will last 10+ years and if not, I can get it replaced under the amazing 10 year warranty! Only complaint I have is have to register to activate the warranty.

i7 Quad Core/ 16GB/ MacBook Pro early 2011. Has worked flawlessly. Apps like Mail and iPhoto that took 30/50 secs respectively to load (I have lots of mail and photos), now launch in 3/5 seconds. Used USB Sata cable and Carbon Copy Cloner to copy system to drive, swapped drives and everything worked, all licenses transferred (except Google Drive needed to be rebuilt). Speed tests (Blackmagic) Show average 515 MB/sec read and 435 MB/sec write. No degradation in speed from first test (a few weeks ago) till now. I think Apple tests their OS with flash drives, so as they increase the Input/Output read write counts when adding features/security protections, they dont notice the issues caused in systems with using hard disks. If you have Yosemite, you need a drive like this. Unfortunately, because apple doesnt support Trim for macs w/3rd party SSDs, you should also plan to replace your drive every year. I do upgrade my drive each year, as I need lots of speed and space. The last three were hybrid SSD/HDD (512MB Seagate/1TB Seagate/1TB Toshiba). The hybrids were slightly faster than a 7200 RPM disk initially, but after a year, each was slower than a stock clean 5400 RPM.

Blazing fast, cut my reboot speed by 50%. NOTE: This is a bare SSD only, without screws, cables, brackets, or cloning cable & software. I also picked up the following: 1) AFUNTA 6-Inch Sata Power Y Splitter Cable Adapter - M/f (Power Cable) to provide power, from Amazon 2) APRICORN Notebook Drive Upgrade Kit (cloning cable & software) from Best Buy 3) A standard 2.5 to 3.5 ssd adapter from my local computer store. Of these three additional items I had the hardest time finding the power-Y splitter. Couldnt find it in any local computer store.

Fast and reliable SSD with a 10-year warranty. Better than Samsung SSD in software as Samsung cloning does not support non-Samsung recovery partitions. So if you want to clone your disk to ssd and keep say a Sony revovery partition, the Sandisk comes with Acronis WD edition that supports cloning/resizing all partitions from source to destination drive. One note, that since it is a WD edition of Acronis, it will not install if it doeasnt detect Sandisk/WD drive. So make sure your external USB to SATA does not hide the name of the drive(like in Device manager) otherwise Acronis will not install. I had bought a Dugol enclosure that did that and it did not work with acronis. I had to use my old Rosewill enclosure to get it to work. After cloning my original disk to it, I installed the Sandisk Extreme pro in my Sony laptop and it worked flawlessly and it is very fast!

Absolutely amazing, took my mid 2011 iMac running Mavericks from a boot time of over a minute to under 10 seconds with absolutely no lag. I cannot recommend it enough - the pro class is definitely the way to go with an SSD and the 10 year warranty is just the icing on the cake. It makes my old iMac feel like a totally different and new machine. With it more than 1/2 full (190 GB FREE), it still is clocking in at 380-410 MB/s read and write - definitely work the money.

I have a MacBook Pro (mid 2009) (MacBookPro5,3) and had been noticing recently that it was spending more time than usual waiting on the hard drive (spinning disk). Having had similar issues over the years with PCs running Windows, I decided it was time for a new hard drive. I could find very little information about this SSD being installed in my generation of MacBook but decided to take the plunge. I decided to physically remove the Macs optical drive as well because it was no longer in use and I felt that it was holding down the SATA speed to 1.5 gigabit which was experience in other PCs. After removal, I filled the slot with silicone to prevent someone from putting a CD in the slot as well as to not cause any airflow issues for cooling. I plugged the SSD into my USB port using a special cable and then used Carbon Copy Clone to transfer all the data. The number of used bytes on the SSD went down dramatically probably because the hard drive marked sectors as unusable. After I physically installed the SSD, a boot was lightning fast and the SATA speed was now 3.0 gigabit.

Being my first SSD I have no complaints. Boot time for my windows 10 5 year old computer is about 50-52 seconds.Amazing difference in computer speed when you add an SSD. By adding an SSD you also lose the spinning sound of a traditional HDD which makes your computer much quieter. Adding an SSD to an older computer can be challenging and I had to do some research but it was worth every penny. Dont forget to download Sandisk SSD dashboard from their website after installing as it is a useful utility.

AVOID!! I purchased 2 of these drives. The first failed within 1 week. SanDisk sent a replacement. The second (the original, not the replacement) then failed 4 months later. Thats 2 out of 2 failed! Usage was mostly just read. There is clearly something wrong with this model. Infuriating for such an expensive drive. I have several of SanDisks 480GB Extreme II drives and had no problem with those. But SanDisk has lost a customer. I am buying only Samsung from here on out. No problems with the Samsung 850 Pro 1TB and 850 Evo 1TB. Given the Samsung firmware fiasco with the 840 Evo, I was trying to avoid Samsung. But Samsung drives have never failed like this. UPDATE: now it is a year later 11/17/2015 2 out of 2 of the replacement drives also failed. Now today, yet another failed. Every single 960GB drive I have purchased, or have been sent as a replacement, has failed. These are running windows virtual machines on esxi (mostly read, not as server, are used as web browsers). I have never had this problem with any of the Samsungs or other brands I have used. This is totally unacceptable. I wasted $1,500 on these drives and untold hours having to reinstall, take the hardware down, etc. Never again.

This was such a great buy. It totally reinvigorated my MacBook pro which now runs faster than my faster than my girlfriends MacBook Air which is a whole model year newer. Migrating all my data from the old drive was easy with tutorials I found online. Ive had this for 6 months now and its been far more durable than my old spinning disk MacBook hard drive. Also, for what its worth this is a best buy on Toms hardware, which is the place to look for hardware recommendations.

Pros: Fast read/write speeds, decently priced Cons: None When it comes to SSDs, there are manufacturers who use their own controller and there are ones who use third party controllers. SanDisk uses Marvell controllers, which are pretty popular. This SSD is built for performance with similar specs to the Samsung 850 Pro. The Samsung, however, uses its own controller, which you can argue is better because they have direct control over the components that go into the SSD, but you probably wont be able to really tell the difference during normal usage. At the time of this review, the Sandisk is $189 vs $217 for the Samsung. If youre looking for a primary SSD for your OS, this wouldnt be a bad choice. The Samsung 850 and 950 are also good, but they tend to be a bit more expensive with similar specs. Intel SSDs are also top of the line, and the price reflects that.
