Samsung 840 pro 256gb SSD(Solid State Drive) is one of the fastest in it class. It uses 8 of 21nm MLC NAND type of flash memory that last longer than any NAND on the market vs the TLC NAND. Last for 60 yrs Raid 45 yr Type 2.5" 7mm (Ultraslim) Form Factor Storage Capacity: 256GB Features Sequential Read Speed: Up to 540MB/s Features Sequential Write Speed: Up to 520MB/s Random Read Speed Up to 100K IOPS Random Write Speed Up to 90K IOPS Warranty 5 Years The 840 Pro has been equipped with Samsung's newest MDX controller (S4LN021X01-8030), this is a triple-core ARM-based controller that of course is SATAlll 6Gb/s to SATAl. The MDX controller s based upon an ARM Cortex R4 (300MHz) processor. It also have it own memory cache 512 MB LPDDR2-1066 The power consumption is very good for laptop and desktop it uses very little of power for top speed. This make this a very good raiding SSD hard drive. The latest Samsung Magician software that update and the firmware and performance benchmark and other tools for the drive. I highly recommend this drive fort any computer update with a faster hard drive performanceRead full review
Pros: This drive is ridiculous. To just say "it's fast" would be so inadequate as to be offensive. Gone are the days of launching BF3 then going into the kitchen to grab a drink and a snack, maybe take out the trash along the way. Now I can't get up to turn off the lights before I'm already in-game. (Not exaggerating) With the current setting I am running on the Magician software, I'm actually getting higher Read/Write speeds then the drive advertises, I'm getting "559/534MBps" on the average of 5 tests. Although my IOPS are much less "68,621/62,456 IOPS", again that's due to my current configuration. So far, this drive has been the epitome of my new build. Yes I do enjoy all the eye candy these games have to offer, but honestly, the ability to play and load this fast makes things so seamless that I wouldn't trade it for anything. (other than a couple "Titan's" that is) On a more serious note; If you are debating between drives, buy what fits your needs and your budget. Any SSD will be astronomically faster than an HDD, after that you start getting into how much space you need and the reliability of the drives. When Buying this drive, know that this is 100% Samsung. The NAND is manufactured by Samsung, so is the controller, the cache, the firmware and the software. This makes it extremely reliable (especially since they did it right). Why else would you get a 5yr Warranty on it? Be sure to have AHCI and TRIM enabled when using an SSD and to set your power mode on "High Performance", or at least set the SSD to "Never turn off" otherwise the TRIM and Garbage collection won't operate to its proper potential. You want to make sure the drive is as fast at 95% Used Capacity as it was out of the box. Cons: This thing makes me feel old and slow. It won't let me use the restroom or grab a drink between matches... The price is still a bit high, grabbing an 830 at a good price would be a better investment IMO, but if you want those higher speeds, this drive won't disappoint. Other Thoughts: On a different but earnest note, please stop rating products poorly on the sole basis that you received a device that was DOA. Maybe if you had 2 or 3 in a row sure... there could definitely be a fault with the product revision then. Also please stop giving poor evaluations due to a lack of accessories, if you want them, pay more for the versions that come with them, just test the product and give you assessment based on performance and reliability rather than pent up frustration due to life and its everyday quirks. It doesn't help the community nor does it provide any valuable information to help people making an investment. Nice to see Manufacturers still giving case badges. Also, for those debating on which storage capacity to go with for gaming, I have Window's 7, BF3, Bioshock 2, War of Thunder, World of Tanks, Planet Side 2, Arma II/Operation Arrowhead, DayZ, along with 6GB of music and other misc programs and I'm sitting at 136GB free of 238GB (Remember that "Over Provisioning" will set 10% aside to accommodate for NAND failure later down the road so you won't lose any information on the drive. Also to prolong the life of your drive, never fill the SSD completely, leave a few GB's on top of the Over Provisioning for TRIM and Garbage Collection.Read full review
It was a bit expensive for a small SSD. Plus, I purchased 2 of them. For just a little more, I could have gotten a much bigger drive. But I didn't want a bigger drive. For me, smaller is easier to watch over. I've read Samsung is among the best SSD, so that was a requirement. I think it was a good purchase because of the brand and the free shipping and multiple drives available at once. My only resentment is the price. One of the drives I received was a low 3Tb use drive, and the other was 13Tb data transfer drive: one low "mileage", one high "mileage". If I need more, I would do it again, even with the resentment, LOL. Preston

The good part: Disk is great, real fast! Now the annoying part: Samsung data migration software is crap, it fails, on a Samsung netbook, AFTER it finishes copying. Yet it works perfect on a Lenovo. It will not let you copy any other disk than the system disk, so hooking up both the source and the destination to a different computer to make the copy is a non-starter. So after a whole day of trying different combinations, I gave up and used EaseUS to copy the disk, which worked on the first try. Now I have a perfectly functioning notebook, with a disk that already has been written more than twice (500GB on a 250GB drive). Good thing it is the MLC version, which supposedly can take more rewrites!
I bought this SSD to improve the overall performance of my HTPC. After upgrading to a 2GB graphics card I noticed my HDD's were the lowest scoring components in Windows performance index. Now that I have the drive installed and working it has drastically improved the performance of my system but getting it up and running was an unexpected challenge. First off, the Samsung software I downloaded failed to migrate the drive with a cryptic error message which left me at the mercy of Windows backup. I had created a system image beforehand but Windows wouldn't allow me to use it for restore, presumably because I was booting from my [current] primary SATA HDD and had my image stored on another internal SATA HDD. In the end I had to reinstall Windows, which was particularly upsetting since I felt I had taken every reasonable precaution to prevent this exact scenario. In summary, this is an excellent product but Windows always assumes that if you want to restore a system image it must be because your primary drive failed, not because you simply want to replace it with a better one. Samsung has software that is supposed to make it simple but it did not work, at least for me. You will be very happy with the performance of this product but getting it properly installed might prove an arduous task.Read full review
