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

Seems to work great, plugged it into my Mac Pro with this adapter:

I bought four of these for a new system. It has been six months now and I am pleased with the speed. However one of the units was defective and when I got around to the installation it was past the Amazon return period. So I returned it to SanDisk the supposed 10 year warranty. After several tedious e-mail exchanges they said I could return it, which I did 6 months ago. After one month they acknowledged receipt of the item. But I have not heard a word since then. Hence the two star review. The ten year warranty is nice but if they dont honor it the promise isnt worth much. It is a good product but dont buy it because of the warranty. Update 9/5/2015 I have had the 4 units now for about a year. Use is moderate. I am a software developer and I use one drive for compiling. The other three receive less use. SMART reports bad sectors on 3 of the 4 drives, ranging from 10 to 40. I am told that this is not sufficient to return the drives under warranty, but most of the drive health utilities that I have recommend that I watch the drives carefully, especially the one with 40 bad sectors. I am lowering the review from 2 to 1 star. I cannot recommend these drives. I got a couple of nasty comments because of a typo in the original post. I said I returned the drive to Samsung. That was a typo. Of course I sent it to the manufacturer (Sandisk). That should have been obvious. You cant just send drives back. You have to call and give them the serial numbers and get permission to return. I had Samsung on my mind because I just purchased Samsung replacements, which so far are working great. It was an honest typo. No need for the nasty comments.

Lasted 7 years

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 had this model of SanDisk SSD (first one returned to SanDisk about a year ago) for just over 2 years. The SanDisk drive is installed in an HP Mini 2102 laptop, that was initially running dual-boot, Ubuntu 1604 and Windows 7 Starter - 64bit. In August 2016, I took advantage of a free ugrade to Windows 10 Home (later I observed this was the 32 bit version of Windows 10 and suspect the switch in bits was related to the Atom processor in the laptop). What a mistake I made. The first problem I observed was screen updates were sluggish and large pauses would occur. I suspected a video driver issue and proceeded to update drivers using a third-party software solution. No changes. Next thing I knew Windows 10 wanted to update to 1607. The upgrade process required a lot of boots and many of them would hang with the disk activity light solid. Contacted SanDisk and they decided to send me a new drive. After restoring from a backup, I was able to get the update to 1607 to complete with only a couple disk hangs while booting up only. I was now observing the disk activity light a lot more. When screen updates would hang, I now noticed the disk activity light being solid and would recover , 20 seconds being the longest. I started using hibernate a lot more to avoid the solid hangs. Also, I observed that when Ubuntu got sluggish, the disk light would go solid, but would recover in less than 5 seconds. Now Windows 10 update 1703 becomes available around April 2017. For some reason, I decided to move the SanDisk SSD to another laptop - HP HDX 16. The update to Win 10 1703 went without a single hang in the HP HDX 16. My conclusion is the SATA/??? controller on the HP Mini 2102 has problems or the driver-controller has issues. The Windows 10 Home driver being much worse than Ubuntu 16.04 driver or the Windows 7 Starter. Going to contact SanDisk again to see if any updates from a year ago and share my experience. Should contact Microsoft about the 32 to 64 bit switch-aroo since the drive may be going into a computer with a lot more memory than the 2.97GB restriction for 32 bit. Or, visualize it on Ubuntu 17.04 64 bit.

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.

I took the plunge and replaced my hdd on my Asus S400C laptop with a Crucial MX100 and it went flawlessly. I then decided to go for broke and replaced the 1 Tb hdd on my Acer TC-605 with the Sandisk Extreme Pro 960 Gb. I love how my computers are no longer clicking away all the time with the poor hard disks seeming to work their little hearts out. I am sure there is a good reason why after a few months, Windows computers just seem to keep working harder and harder and get slower and slower. I know it is because of all the stuff we put into them, but I have always kept my computers cleaned up and it still seems to happen. I am hoping that changing to ssd drives in both my computers will remove some of that issue; right now it seems to be working. I just replaced the hdd on my desktop last night and used Farstones DriveClone 11 Free Version (http://www.farstone.com/software/drive-clone.php). This software is easier for the non-geek because it does one thing exceeding well--clone your disk. It also has a fast mode which I used to back up my ~700 Gb of files in only about an hour. The only thing I had trouble with was getting the computer to recognize the ssd simply because I am not really into this stuff. I did a bit of googling and found how-to sites on how to use disk manager to assign a new drive letter and then I was fine. Another issue I had was in physically installing the ssd in the computer. I went to a computer store and a guy simply gave me a plastic 2.5 to 3.5 chassis. This was helpful but Acer bolts the hdd up against the side of the case and doesnt use the traditional horizontal stacked configuration any more. I ended up installing the ssd on the plastic chassis and then simply using wire ties to hold the whole configuration in the slot where the old massive 3.5 hdd had been. As this computer just sits and never moves, I think that will be just fine. If the idea of doing that bothers you, then you may wish to open up your computer and see if you can find the correct 2.5 to 3.5 adapter. I scoured Amazon and could find nothing that had the correct configuration of drilled and tapped holes to mount in my Acer. (I needed to be able to mount to the bottom of the ssd adapter.) If you are contemplating replacing your hdd in either a laptop or desktop, the time has come. Prices have gotten reasonable and the technology is mature. I can sit in my home office in complete silence, no longer listening to that annoying hard drive always working away--it is amazing how nice silence can be. In summary here is what you need: 1. Find a ssd you like. I recommend a name brand with a large installed base so that you can capitalize on others experiences. I have a Crucial in my laptop and a Sandisk in the desktop and am pleased with both. I went a little more budget on the laptop but stepped up on the desktop and got the best: the Sandisk Extreme Pro. You cant beat a 10 year warranty. Computer years are like dog years so a 10 year warranty is like a lifetime. Also, get the largest capacity you can afford. 2. Get the ssd enclosure. You will need this enclosure because you have to have a way to connect the computer to the new ssd in order to transfer the system from one hard drive to another. In other words, you put the new ssd in the enclosure, transfer all your stuff to the ssd via the usb port on your computer, and then remove your old hdd and replace it with the new ssd. I got a Sabrent and it was fine. I didnt even bother to put the cover on as all you really need is the usb adapter. Search Amazon for hdd enclosure 2.5 inch. 3. Get the migration software. Again, I used the free Farstone DriveClone 11 and was really pleased. I downloaded others but the Farstone is easiest for non-geeks if all you are doing is cloning. 4. Set aside some time and take the plunge. While pricey, making the change removes a huge annoyance (noise) for those of us who live on our computers and it also speeds up booting and working with large files. My computers are fairly new so if you have older computers, you may want to do more research. I so love the silence. The speed is nice too!

I originally bought this to see if it would be compatible with SanDisks Ready Cache software. (It isnt.) I have a 5930K based custom computer. Originally, it had a 1TB HDD with a 32 GB internal SSD cache, as well as a 32 GB external SSD Ready Cache. I still only got a 5.9 for the storage User Experience Index. I rebuilt the computer by replacing the HDD with this SSD, and moving the original HDD to the D: drive. The storage user experience index is now 7.9. My wifes laptop has a WD hybrid 120GB SSD plus 1TB HDD drive, and her storage user index is 7.8 When I rebuilt the computer, I started from scratch, and Windows 7 installed the fastest ever. The key was this SSD, and I loaded Windows from my Blu-Ray Writer. I have a lot of gadgets on my screen, and after I log in, they appear almost immediately. Ill be taking an FPGA programming class next year. I had one this past winter, and the software spent a lot of time reading and writing to disk. This will speed up the calculations immensely.

I bought this to upgrade my desktops drive from an HDD to an SSD to take advantage of the speed increase. Let me just say, it makes a world of difference. Programs launch much quicker and the computer starts up and resumes from sleep much quicker. My only note is that if you are planning on putting this in a desktop, buy a 2.5 to 3.5 drive adapter so that you can mount it in your case, as desktop HDDs are 3.5 inches and SSDs (including this one) are 2.5 and they will most likely not fit in your case. But this drive itself is AWESOME! The included SanDisk drive utility is also really useful for figuring out specifics about your drive including the life left in it.

TIP for those using this as their primary hard drive: turn off unnecessary WINDOW SERVICES that read and write to an SSD. Reading and writing to this SSD, reduces lifespan. I will try later to update this sharing with you what services I have turned off that are unnecessary and believe me, a LOT of MS services ARE unnecessary, like ANY of the Remote services IF YOU DO NOT LOGIN TO YOUR HOME PC FROM ELSEWHERE. If you dont, turn these off as they are a security risk to begin with. I will be back later to give you all a list. OH, and be sure the TRIM feature is on by installing the SanDisk tool. Go to their site to download it. It will sit in your task bar and let you know temperature, read/write status, capacity, etc. TRIM is auto set when you install this drive, but default. Also, an SSD are CHIPS, not platters. TURN OFF: ANY disk defragger (SSDs do not require defragging) ANY read/write utilities (NOT apps like MS Office that you install) Windows INDEXING and SEARCH (turn BOTH off!) IF YOU HAVE A HDD SLAVE DRIVE like a Western Digital SATA drive (not another SSD): Move your PAGEFILE to the slave drive root for reading and writing. To save time, go to these sites and follow their instructions which fit your situation: (...)
