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

To get the best performance to 530MB/s seq read, youll need to install in main slot of your machine, with high speed SATA3 6.0Gb/s port Otherwise the transmission speed will be limited by SATA2 of your optical disc drive slot. Anyway good SSD in medium level with SanDisks own 64Gbit 19nm MLC cell, old Marvell 9187 but more stable, and cheaper than 850 pro. if you have more money you can choose Intel 730, or PCIe for desktop. Ill give a s*** to sumsungs so-called 3D V-nand, you know reason. Avg. random write 65-95MB/s, enough for Win10

Installed in my 10 year old HP (g72) laptop along with an upgraded CPU & 8gb RAM. It installed easily, cloned easily and has been working flawlessly for over 6 months. While my laptop has only a Sata II connection and cant use this SSDs full speed capabilities, it is still rocket fast & has brought this old girl up to speed with new computers! It comes with software to monitor and analyze it. A nice touch vs the Samsungs Ive used in other family laptops. This worked even with sata 1 speed connections and made s dramatic improvement in speed. In my HP Laptop this cut the start up time from almost 2 minutes down to under 30 seconds. After the ram & CPU upgrade Im at 20 seconds for start up time! SSDs are one of the easiest upgrade you can make & definitely the one upgrade which will give you the biggest speed bump! I would honestly recommend this even over Increased RAM because the impact is so dramatic on increasing the computers speed!

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.

UPDATE: After about a year, my new drive failed. My Mac would periodically grey screen after freezing ever since I installed this drive. In January it would grey screen a couple times a day. Actually what happened was that one window would freeze then eventually another and another and finally the entire screen would go grey, but the machine would track the mouse for a while longer. One day I noticed that I could not do an image backup and checking the logs it always failed on the same file: ta da! A read error on the disk was the only cause. I tried to access the file directly and it caused the freeze. The Extreme PRO had been causing the problem all along but had finally left a clue that showed it was the culprit. This was disappointing but the real fun occurred when I tried to fix it. First I downloaded a SMART utility to run on my mac and evaluate what was wrong. This was VERY difficult since it involved installing all kinds of packages on the Mac and actually compiling source code to install the linux utilities that scanned the SMART status. The SMART utilities showed that the drive had had about 20 bad blocks and thousands of power cycles - which I presumed was due to the Macs sleep function. I know that power cycles are bad for SSDs but I think I have the right to assume that a major manufacturer would have considered this. My first thought, as the SanDisk rep made in a comment to another bad review, was to upgrade the firmware. Unfortunately Im on a Mac and apparently SanDisk thinks Mac users dont matter, because their fancy SSD utility that updates the firmware only runs on windows. First I tried running it in a VirtualBox Windows machine, but it couldnt find the SSD. So I tried their process to build a flash drive image of their utility and after hours of trying I had to give up because the Mac would not boot from the flash drive, in all likelihood because the utility was designed for an older version of MacOS. I finally succeeded in burning an ISO to a CD with the Macs superdrive. Thank god my imac was old enough to have one! After nearly 12 hours of reading online knowledgebase notes, SanDisk support community postings and trying everything I could with my nearly 40 years of computer experience, I finally was was able to run the utility on the CD and update the Extreme Pro. By this time I was fuming at the waste of time, the poor attention to support materials, and the unmaintained utilities. Not to mention that one of the support articles said that OS X El Capitan was probably not compatible with the drive (ridiculous!) Once the firmware was updated, the drive started to work and has worked for the last few weeks without issue. However I no longer trust it. I would like SanDisk to replace it. However their return policy is ridiculous: you have to remove the drive from teh computer and take pictures of it and plead for a replacement, then wait while your drive is sent in and evaluated before they send you a new one. Once its out of the computer I cant run any tests on it, so theyll have to take my word for it but I bet they wont. And have you tried removing a hard drive from an iMac? Its a multi-hour procedure. Am I going to open the iMac twice to replace their drive when they send the replacement? Or, live without a computer for months while they decide what to do with my drive? Their support policies are ridiculous: Im going to have to buy another drive just to keep using my iMac while they fix my old one. OLD REVIEW: I replaced the hard drive in my 2011 iMac with this and it ZOOMS! I needed a kit from Otherworld Computing to do it (especially to get the screen off and adapt this drive to the Apple-specific connector.) Boot speed is up, used to take 2-3 minutes, now takes 20 seconds. The computer runs cooler too.

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 purchased the SanDisk Extreme Pro SSD 2-3 years ago, not a single hiccup. I purchased my 2nd in November 2015. I even purchased an Extreme Pro USB! This drive is GOOD. My computer starts up fast and with a 10 year warranty this company has your BACK. As a computer tech, I see everything from dead HDDs (hard drives) to HDD overload. When a customer wants fast and sustaining, I give recommend this drive. I had a terrible experience with the Samsung 850 EVO so for anyone trying to pick from the two, this one is the easiest and most reliable. The speed isnt even a question. My computers start in under 7 seconds, with an update 15 seconds. Thank you SanDisk, I sell your products, I buy ONLY your products. For anyone serious about speeding up their computer and looking for a reliable solution. A bang for your buck, THIS is it.

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.

The warranty on this drive convinced me to go SSD, and the 960GB size let me replace the spinning magnetic 1TB drive in my PC without losing much capacity. To replace an existing disk you will need disk cloning software and a USB3.0 to SATA 6G cable / adapter. I bought the IO Crest adapter, and used (the free version of) Reflect by Macrium. It did work - on the second try. The first try failed in the middle. The second try succeeded probably because I left my computer completely alone while it was in progress. Now, to the review: the speed up in boot time is quite noticable. The speed up in Adobe Photoshop Elements loading my Catalog of over 1000 photos into the Organizer is more than noticable, its amazing. The monitoring program that comes with it (SanDisk SSD Dashboard) is very reassuring. Right now it shows that the drive is in good health, has 100% of life remaining (ie, has not used any of its spare blocks) and its internal temperaure is 77 degrees F. It is quiet, cool, and lightning fast. In summary: I should have done this sooner!

I had no idea just how much faster my computer would be with this hard drive. Its one thing to intellectually know the difference in speeds between a spinning platter and flash memory, but to actually experience it is something completely different. If you want to use it in a PC, you might want to get a mounting bracket to make it fit in a full size bay, as this is a 2.5 inch drive, but it should fit perfectly into a laptop drive bay. Also, a Google search on optimizing your OS for running on an SSD could serve you well. A modern OS does many things to improve traditional hard drive efficiency that will have no effect on an SSD, and might even use it up more quickly. Pro tip: Make sure you have plenty of RAM and then disable Virtual Memory. Or use a standard hard drive for Virtual Memory, but I prefer the first option.

I cant say whether this is the hard drives problem or not but my computer repair had to purchase another SSD drive to get my computer to boot. This drive is now a secondary drive but I dont know why it originally got corrupted and my computer wouldnt boot. Sandisk has always run well for me and this is the first issue I have had.
