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

An absolutely incredible upgrade. My initial benchmarks indicate boot time at 20% of the original time, maybe lower. Database programs and processes run a lot faster when using the disk for a database. Even browsing and video is greatly sped up, as the time to load cached images and video content is very fast, so it even appears to improve the quality of the displayed video. I guess with the old green hard drives, the time the browser program takes to load the data is enough time to reduce image quality. An absolute must for any personal or computationally intensive business computer. Certainly good for servers too.

Its added up to a good chunk of cash, but this is the second 960GB SanDisk Extreme PRO I have bought. The first one Ive valued so much, that I took the plunge (while the prices have been VERY low!) for another. The main aspects of this drive that I really value: It should last over the long-haul. Its 960GB instead of 1TB for a reason...and thats partially due to durability. That, along with it being designed to sustain its performance over a much longer period of time, and Im pretty pleased with the long-term usefulness of this. Will faster SSDs become more common over time? Of course. But this unit is already very fast, and thats even for heavy video & image-sequence usage. Ive had some hard drives for years and years, and I think this will be an even more solid investment for a long time to come...with long-term durability in mind.

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.

Up until now I have found no issues. I used some disk-checking software and AS SSD Benchmark to test this drive. The result is quite good. But as we all know, the performance is not so important. As a data storage device the stability, reliance and durability are most important. As far as I know, this SSD uses MLC nand and Marvell controller chip and has an unbeatable 10-year warranty, which can resolve all my worries. That is why I choose Extreme Pro Series. That is why it is worth 5 star.

Would have given 5 stars IF there was decent support on website or included with SSD. Tried to install (clone) on Win10 laptop using the Sandisk Installation kit. It doesnt work so save your money!! I ended up downloading a trial/demo copy of Paragon Backup and Recovery 15. It worked perfectly. It worked so well I purchased a copy from them. Once installed the Sandisk Extreme Pro works EXTREMELY well. Good product BUT lacking documentation and installation support.

So everything youve read about this drive is pretty much spot on- its really fast and its nearly a TB of storage. Just what I needed to put all my photos & videos on for doing my editing in Lightroom/Photoshop/etc. Its definitely worth going Thunderbolt over USB2/3 if youve got a Mac to eek out the full performance of this drive. That said, there is one problem- SSDs like this do not like being turned off for months at a time. Without power Ive noticed some data corruption of some of my files. Luckily nothing major, but it was bad enough that I wasnt able to recover the data and I had a few corrupted image files. Now I keep my two Extreme Pros in a cheap powered USB enclosure when not in use so they dont have this problem and Ive not seen any more corrupted files. This is a general issue with SSDs and not specific to these drives from what I can tell, so its just a limitation of the technology. This means these drives are NOT good for archival purposes which is too bad.

I have a recording studio and a recent Mac Pro Cylinder computer. I needed a fast external drive for making music with my DAW software (Logic X). I tried a few different USB3 SSD and hard disk connections until I came to this drive. I use these in my Atomos Ninja 2 video recorder and that is how I got on to using them for my DAW. This disk mounted on an Atomos USB3 drive sled reads and writes at over 360 MB/s as measured with Black Magic Design disk speed test. This was the fastest drive Ive tested. By contrast my OWC USB3 SSD only writes at 150MB/s and reads at 205MB/s by the same measure. My Seagate 7200 3-TB hard disk drive which is Enterprise class reads and writes at 180MB/s so this SSD is really a big step up in speed. Its working great as my DAW SSD now, fast, quiet, cool running and Amazon makes it affordable and easy to get. Good music and good computing to all!

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!

I installed this as my C-drive on a new Levono I7 PC with 16MB RAM. I took out the original HDD with Windows 8 installed and put my own copy of Win 7 OS on this SSD along with my programs. My computer is SILENT and SO FAST!!! Like all SSDs this drive makes no sound at all (no moving parts) and requires no fan cooling. The only trouble I had was adapting its tiny size to the 3.5 bay in my tower PC, which is a mechanical problem. I love this drive!!!

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.
