Fast and brilliant, but if you have the original Extreme, just skip this for now
By Stephen M. Lerch
I now own this Extreme II SSD.
I also own a 240 GB SanDisk Extreme SSD where Windows 8 was installed. This is the original Extreme not an Extreme II.
I copied the original Extreme(full Win 8 backup) to this new Extreme II drive and did a comparison. I would struggle, in real world testing, to be able to tell you what the difference in speed does for me between these two drives.
That's going SanDisk Extreme SSD to SSD. If you are still running on a platter based hard drive, the speed boost seen either in the Extreme II, or the now less expensive Extreme, is absolutely one of the best choices you can make in order to make your PC (that's Mac or Windows based PC) perform at a level you can't see with a platter drive.
What I recommend is to buy an SSD for the OS and apps. Use a platter based drive, 1 TB+, for all of your media and files. I also highly recommend a physical USB3 backup drive to backup your data as well.
So what's the difference on paper between the Extreme and the Extreme II? Random reads and writes are roughly 40% faster on the Extreme II. Random reads are only 7% faster. Sequential reads and writes are about on par, with the Extreme (original) eking out about 10 MB per second better than the Extreme II. If I had a choice though, the Random Read/Write, being both a lot, and a little, better on the Extreme II, and if there was price parity, I would go with the Extreme II. You do more random reads/writes than sequential, generally speaking. You aren't likely to really notice the difference in practice moving from one to the other, unless you do a lot of hard drive intense operations.
If you are a gamer, just go with the Extreme II now. You may not notice the differences in the real world, but when it comes to performance, if you are a gamer I will always recommend the best you can afford, and right now, the Extreme II in my mind is one of the best options available.
So in the end, if you already have an Extreme SSD (or similar performer from other manufacturers), you probably can avoid the upgrade. If you don't already have a performance focused SSD, or have a platter based hard drive only, I highly recommend the Extreme II (or even the original Extreme).

SSDs will make any computer feel like it's from the future!
By MOAR COARS
I recently got a brand new laptop (Lenovo ThinkPad T431s) that comes with a Toshiba 7200rpm HDD so I decided to get an SSD to speed things up because I got tired of waiting for applications to load. So I decided to go with a SanDisk Extreme II 240 GB and man, SSD's will make any computer feel like it's from the future. The ThinkPad T431s is already fast because it comes with 4GB of ram and a core i5-3337U but swapping the HDD with an SSD made it 100x faster. I feel like HDDs really hold back a computer's performance. The SanDisk Extreme II 240GB literally blew me away by the performance that it has. My Windows 7 disk experience score went from 5.4 to 7.9 which is the highest it can go on Windows 7.
I do a lot of backups and transfer large files with my laptop and it used to take forever when I had my HDD but now everything is blazing fast. I know that this product literally came onto the market just a few days ago but it seems it's receiving very good reviews and so far I'm very impressed! When I was on the HDD, I would get around ~5hrs of battery life but now I'm getting around 6-7hrs. I travel a lot so battery life is very important to me and being able to have an extra 1-2hrs is awesome. This SSD is quite an improvement from my Toshiba HDD that I had before in my laptop but I'm really impressed by how lightweight this new drive is and how fast it.
It also generates almost no heat and is obviously silent to the ear. I couldn't stand the weird noises that my Toshiba HDD would make during the night. The access and read speed are as advertised and I did a benchmark with CrystialDiskMark, the results are below. I use my laptop for video editing/web development so I use programs like Adobe After Effects, Dreamweaver and Photoshop quite a lot. My work-files are usually quite large (2GB+) and it used to take forever to load them when I was using my Toshiba HDD but now it takes less than a second to open them with the SanDisk Extreme II 240GB.
The installation process is very simple. You just have to make sure to enable AHCI in the BIOS (not IDE) so the SSD can work like it should. Also, make sure you flash the latest bios for your motherboard first before you install this drive. I was getting half the advertised read/write speeds but once I flashed the latest BIOS for my motherboard, it was all good. Another important thing to do after installation is to install the latest SATA drivers and chipset because it makes a huge difference. I got 100MB+ in read and write after installing the latest SATA drivers.
I never get to see the entire Windows boot animation with this SSD which shows how fast this thing is. Windows 7 starts in ~6 seconds and shuts down in less than that. Everything opens immediately and applications load super fast and run great. I have disabled indexing, prefetch, defrag and hibernation because they are not needed when using an SSD. I have even gone ahead and completely disabled page file because most people recommend it to disable it since SSDs are already fast enough and benefit from it. I would recommend you keep page file if you are on a HDD but not on a SSD. You also save a ton of free space if you disable page file which is great.
These are the speeds that I got when benchmarking it with CrystalDiskMark:
---------------Read ------- Write
Sequence: 531.26MB/sec --- 493.21MB/sec
512K: 281.48MB/sec ------- 453.32MB/sec
4K: 33.19MB/sec -----------161.21MB/sec
4K QD32: 376.21MB/sec -----321.33MB/sec
As you can see from the result above, the speed that this SSD delivers is right up there with the big dogs.
Pros:
+ Longer battery life in a laptop.
+ Sturdy
+ Great Packaging
+ Blazing Fast
+ Cheaper than the competition
+ Fast boot times/applications
Cons:
- None
Overall, I highly I highly recommend upgrading to a SanDisk Extreme II 240GB if you are still on a HDD. If you are using a HDD on your laptop and want to make your computer feel like brand new then upgrade to an SSD. The SanDisk Extreme II 240GB made my laptop feel like it was from the future with the blazing fast speed. I also got an extra 1-2hrs just from upgrading to an SSD. The quick boot and super fast load of applications is amazing. The SanDisk Extreme II 240 GB is also a tiny bit cheaper than the competition.

Bare Bones - Bricked After 8 Months
By Daniel G. Lebryk
This SanDisk SSD is a bare bones drive. The box contains two items, the drive and a plastic spacer, nothing else. If you have done an SSD upgrade before and have the SATA to USB adapter (or a SATA drive enclosure), or are going for a clean install of the new drive; this is the drive to purchase.
February 24, 2013 Update - Well the unthinkable happened, the drive went totally 100% completely belly up - it is bricked after eight months of use. The drive died with absolutely no warning - no read errors, no noise, it just died instantly. Lesson very well learned on this drive - back up, back up, back up. I'll say it again, back up your drive every single day. The bad news - the drive failed. That's just not a good thing at all.
So of course this review goes from five stars to two. SanDisk gets an extra star for support. Their on line chat was outstanding, within 5 minutes they agreed with my diagnosis, and started the RMA processes. They will take the drive back, pay for shipping, and send me a new drive - in about a week. I understand, there isn't a way to ship me a new drive immediately and I will just have to wait. In the meantime, I'm heading over to the Samsung page and buying an EVO 500Gb. When the SanDisk arrives, it will go in an old netbook I don't use much.
March 13, 2014 Update: There was a problem with SanDisk's customer service computers and getting me an RMA. One afternoon I received a phone call from somebody higher up in customer support. He managed to ship me a new drive and get me the return label for the dead drive. It took a few more days and the replacement drive arrived. Kudos to SanDisk for not giving up and making the replacement right. I have installed it in an ancient Acer Aspire One netbook (the one where you have to remove the motherboard to get at the hard drive). It works perfectly in that computer. In fact the computer feels like I just bought a brand new computer - not something over 5 years old.
I was fortunate with this drive - it was in a MacBook Pro and I was pretty religious about running Time Machine for my backups, the latest was 3 days old. I also saved the original mechanical drive. It wasn't hard swapping the drives. What took a ton of time, Mavericks came out in the interim, and I had to upgrade along with all the updates applied to that mechanical drive. Once the updates were done, I was able to run the Migration Assistant to use the three day old backup. Everything went smoothly with no data lost. It did take five hours. And now I hate my laptop. It is amazing how quickly you get used to SSDs, the computer is just dirt dog slow now.
Did I mention that you should back up your computer? On a PC, go install Second Copy immediately. On a Mac, start using Time Machine with an external drive.
Original Review:
If, on the other hand, this is your first SSD installation; it would be much better to purchase a full retail kit - specifically the Samsung 840 series.
I used this drive to upgrade my MacBook Pro 15 inch, 500GB mechanical drive. Critical first step before buying an SSD is to check how much data is on your mechanical drive. If it is less than the 240GB, the drive will work fine. If there is more than 240GB of data on the larger mechanical drive, either delete things or buy a larger SSD. The job took about four hours to do the upgrade. This was the first time I've upgraded / cloned a drive, so I worked slowly. I could probably get this done in about 3 hours now.
Feb. 7, 2014 Update - This drive has been in my MacBook Pro for almost eight months now - it has worked flawlessly. I pay a bit more attention to what I put on the internal hard drive, there is only 63 Gb free on the drive. No signs of slowing down. I've gotten used to the speed, mechanical drive computers are almost frustrating to me now.
How to perform the installation (SanDisk doesn't pack much in the way of instructions or have much information on their website - you kind of have to find this stuff searching the internet):
If this is a clean install - bolt in the hard drive.
This might get a little complicated in a desktop; SanDisk does not pack an adapter tray with the drive. You're in luck if your case has a 2 1/2 inch bay. If not, you'll have to buy an adapter plate. This OCZ plate will work just fine: OCZ Solid State Drive 3.5-Inch Adaptor Bracket 2 OCZACSSDBRKT2. The Samsung 840 drives contain an adapter plate.
Boot the computer on the installation disc and follow the instructions. Literally, there is nothing else to do. An SSD is no different from a mechanical drive for a clean install. Win7 recognizes that the drive is an SSD and adjusts the settings appropriately.
If this is cloning, or copying over the exact mechanical drive to the SSD:
Find cloning software (the Samsung kit includes cloning software). Since I did this with a Macintosh, I used Carbon Copy Cloner. The software is free to use as a trial to simply clone a hard drive. I didn't need any of the other functions, so I just used the trial software. SuperDuper is another Macintosh alternative. Macrium and Paragon are excellent free package for PC's.
Next you have to connect the SSD to the computer via USB. This can be done with a SATA to USB adapter. This where things get weird. The Samsung install kit includes an elegant simple adapter. In the case of the SanDisk bare bones drive, either you can buy a universal SATA to USB adapter (somewhat expensive) or a SATA drive enclosure (a lot less expensive). So go figure, it is cheaper to buy an enclosure than a simple cable. An enclosure is really a good idea - your old mechanical drive can go someplace useful after the swap - it can become a good external hard drive with an enclosure. What are the price differences? A good USB2 enclosure can be had for $8. A USB2 adapter cable is around $15. A USB3 adapter cable is around $20-29.
Once the adapter is connected to the SSD, plug it into a USB port on the computer. In the world of PC and Mac the drive has to be formatted. For PC, format the drive with NTFS (use the Storage > Disc Management portion of Computer Management (right click over the My Computer icon and choose Manage)). For a Mac there are some odd little steps to follow. When you plug in the drive the Disk Utility will automatically run. You have to format the drive and then go through a special HD backup partition step. Carbon Copy Cloner describes every step perfectly. Just follow those instructions.
Launch the cloning software. Now comes the fun part, waiting and waiting and waiting. It took just over two hours to copy 199GB of data from my Mac hard drive over to the SSD. It's important to understand that the SSD and the computer will get pretty darn warm while this is running. Given that it took so darn long to copy the data, and I wasn't going to format my mechanical drive right away, I didn't bother verifying the copy.
Once the clone is done, shut down the computer, remove the old boot drive, and install the new SSD (dirt dog simple on a PC). On my MacBook Pro this wasn't too complicated (there are instructions all over the internet on how to open up a Mac to replace the hard drive). I pulled all the small stainless steel screws and lifted off the cover. The hard drive is to the right of the battery (the big long black thing). Be careful about not touching anything inside the computer and you don't have to unplug the battery (looking around, unplugging that thing looked more complicated than I wanted to tackle). The hard drive is held in with a clamp (like those stocks used in Colonial times to punish people - the hole for the head and two for the hands). You only have to remove the one clamp that is farthest away from the computer body. The drive will now slip out of the other clamp. Pull off the SATA connector. Remove the four mounting screws that are Number 6 Torx. There isn't really a good way to remove these without a Torx screwdriver (the screws are really tight and pliers around the screw might mess things up, you might MacGyver it, but it could go wrong).
Mount the new SSD. Screw in the four Torx screws on the side of the drive. If you really want to make sure this is a secure mount, place the self-adhesive plastic spacer on the top of the drive (this is the black and red SanDisk label side), and you can remove the little plastic tab for pulling up on the drive from the old mechanical drive. Reconnect the SATA cable. Replace the stocks clamp. Replace the back cover and the stainless screws.
Voila - the work is now done. Start up the computer. You will be ultra-disappointed on the first start up. Somehow the Mac got a bit confused and it took a couple of minutes to start up the first time. Once the system checking and hardware stuff was updated, and my desktop appeared, the computer was instantly available. Boot time is much faster now. I rarely power down my Mac, but cold boot a fairly fast 2 minutes with the mechanical drive. Once the desktop appeared it took another thirty seconds or so to actually be useable. With the SSD gray screen is around one minute and once the desktop appears every single program is instantly available.
The big win with this SSD in Mac land is how fast applications start. Safari is virtually instant, blink of an eye. IPhoto is a little longer, maybe 10 seconds (it used to take a good 30 seconds to get rolling). IMovie is incredibly fast now. I use Microsoft Office 2011 and really hated starting up any of that software on the old drive. Now after the SSD I click on Word, the program is running within about 10 seconds. I can wait that long.
The only hitch I ran into was with Microsoft Office. For some reason, once I cloned the drive, Microsoft decided I had a new installation. I had to enter my product key again. Lucky for me I could find the key. Before cloning the drive, you might want to look around for the product key in Office someplace.
This is one darn fast drive. The only thing to watch is drive space. Macs tend to throw files all over the place and not care a lot about how much storage space is used. They are then difficult to prune down to get rid of no longer needed files. I chose to copy everything over from my old drive to the new without any housecleaning beforehand. I did find a set of movies I can get rid of, leaving me with about 60 GB of free space.
With an SSD, an external drive will be critical. I don't have a lot of trouble with that because I currently use a 2TB external drive for my Time Machine. Big files can sit on that drive instead of locally.
I happened to have all the tools I needed for this migration. That was super lucky; I just finished building a PC with a Samsung 840 drive. If I didn't have those tools, this drive would be really hard to install. Honestly, if you don't have the tools, the Samsung is a much better, cheaper choice. Yeah, OK, somebody ran some benchmarks and says some of these drives are faster than others. That's benchmarks, not real world. At some point, a blink of an eye is fast; half a blink of an eye doesn't appear to be faster. Bottom line, you'll never see the difference with real files and real work between the drives.
This is an excellent bare bones hard drive. Oh, the warranty was increased from 3 years to 5 years; my owner's manual was updated by hand. If you've never experienced an SSD, it is the world's best upgrade you can do to speed up your computer.
