Samsung's TurboWrite technology, 840 EVO can deliver much faster sequential write speeds compared to the previous 840 model, tripling the speed from 130 to 410MB/s in 120GB drives, and doubling it from 250 to 520MB/s in 250GB drives

I bought this SSD to replace a noisy one terabyte drive in my front room, SFF media centre computer. Much faster than the old drive and because it's an SSD it produces no sound or heat which is ideal for my use. I have one more hard drive in that box to replace and I'll be purchasing another Samsung SSD.

Amazing upgrade for old laptop. - Instructions to install.Jan. 9 2014
- Published on Amazon.com
I had a very sluggish ASUS laptop that was about 2.5yrs old. It had a 2nd gen Intel Core 2 Duo processor. It took forever to boot up and website browsing was very slow. I mainly use my laptop for checking e-mail, web surfing and downloading photos from my digital camera. I'm not a power user so I just couldn't rationalize spending hundreds of dollars to replace it. Plus, I'm not a fan of Windows 8 which is installed on nearly all new laptops which dissuaded me from buying a new laptop (I have Windows 7 now).
Lately I've been hearing how replacing the old mechanical hard drive with an SSD would increase performance of any PC. I wasn't sure how much of an improvement it'd be since I wouldn't be updating the processor. After I put in the SSD it was a whole new world. The laptop booted up in seconds instead of minutes. Applications opened faster and everything was more responsive. Until now I never realized how much the mechanical hard drive bottlenecked the laptop's performance (as opposed to the processor). I don't think adding more RAM can increase performance this much.
I want to let you know that replacing the hard drive was super easy. I was overwhelmed at first because I couldn't find any easy installation instructions on the web. I was afraid that if I did it wrong I would lose all my data (especially my photos) or brick my laptop because I don't have the Windows Operating System installation CD (p.s. you don't need it). I thought I'd share my installation experience for people who are novices like me.
The steps below are for upgrading the hard drive on a regular PC laptop (i.e. I'm not sure if my instructions will work for a MacBook). Most people will just be swapping out their hard drives and likely won't have an external hard drive to back up their data. That is perfectly fine. Also, you don't need the Windows OS installation CD because you won't be reinstalling any software. The steps below will copy EVERYTHING from your old hard drive onto your SSD including your Operating System, Applications, Programs, Photos, device drivers, etc.
Before starting you need to make sure you have the following items:
1) Make sure your new SSD has enough space to copy all your existing data. My original laptop HDD was 300GB, but I was only using 60GB. I bought a 120GB SSD and that was fine. 2) Small phillips head screwdriver (hopefully you already have one in your house) 3) 2.5" SATA III enclosure (purchased separately). I bought the following Sabrent USB 3.0 enclosure and it actually came with a phillips head screwdriver. Personally, I wasn't crazy about the Sabrent enclosure because it looked and felt cheap, but it did the job. Sabrent USB 3.0 To 2.5-Inch Sata Aluminum Hard Drive Enclosure Case (for 9.5mm, 12.5mm 2.5-Inch SATA-I, SATA-II, SATA-III HDD and SSD) Black (EC-TB4P) 4) Hard drive cloning software (Samsung includes this with their SSD).
BASIC steps to upgrade/swap hard drives:
1) Install SSD into 2.5" SATA hard drive enclosure. 2) Plug enclosure into USB port of laptop (USB 3.0 will be a LOT faster than USB 2.0). 3) Install hard drive cloning software onto laptop (Samsung provides the software with SSD). 4) Follow instructions to clone old hard drive from laptop onto new SSD (Samsung software makes it very easy). 5) Shut down your laptop, unplug the power, remove battery and uninstall old hard drive. 6) Remove SSD from enclosure and install into laptop. 7) Reinstall battery, plug in power and restart laptop. 8) You're Done!
Restarting your laptop in step 7 will be super fast. That's when you know that the new SSD was worth the upgrade. [....]

Makes a noticeable speed difference from traditional hard drivesSept. 2 2013
- Published on Amazon.com
If you need some more speed from your existing PC (especially laptops) this might be what you are looking for. Let's face it, most decent computers have enough RAM (4GB or more) and a fast enough CPU for "general purpose" use. But if you find your computer is still sluggish overall performance is probably held back by the hard drive. Traditional hard drives are mechanical and are limited by the time it takes for the platters to revolve and the mechanical components to position/seek before data can be read/written. An SSD is an "electronic" hard drive with no moving parts - which means significant speedups since there is no waiting on mechanical parts. In addition SSDs are more resistant to vibration/mechanical shock than hard drives.
Replacing the stock hard drive on a laptop (Win7, 64-bit) my Primary Disk interface score went from 5.8 to 7.6 (note the highest score is 7.9) and the laptop feels much snappier - boots in half the time too. I used the included Samsung Disk Migration software to perform the disk clone (using the SSD in an external USB SATA adapter). When it was finished I simply swapped the hard drive installed in the laptop with the SSD and Windows booted as usual. Note that you need to have a functional Windows installation for the Disk Migration tool to work - you install the tool under Windows like any other app (the tool is NOT a bootable CD with its own OS).
It's too early to determine reliability, which is the one concern I have with SSDs in general. SSDs use Flash memory and some SSDs use MultiLevelCell Flash (stores more than 1 bit per cell) - this allows pricing to be lower for a given capacity. Samsung uses 3 bit per cell memory in the 840 EVO (they call it TLC) using a smaller process technology which could be somewhat detrimental for potential reliability. However the drive's spare area (for the 250GB model) is 9% allowing for remapping in case of bad/worn out blocks. I feel that Samsung is being conservative with design/flash lifetime and that's a good thing - you don't want your fast drive to drop dead or risk a data loss.
THE GOOD: + Reasonably priced SSD. I bought the 250GB model to replace a 500GB hard drive, still had 50GB free space with the SSD (even though it was smaller in capacity). + Has Disk Migration tool on CD - this will do the cloning operation from your hard drive to the SSD. + Hardware supports AES-256 encryption. + Samsung makes all of the components, from the Flash memory chips to the MEX controller. I would expect better integration and more realistic endurance ratings as a result.
THE BAD: - I didn't realize it at the time but Samsung sells this SSD packaged 3 different ways: 1. the bare drive (with software). This is what I bought. This DOES NOT INCLUDE A USB to SATA adapter. 2. the drive/software & accessories for laptop installation (including a USB to SATA adapter) 3. the drive/software & accessories for desktop installation (including a USB to SATA adapter) NOTE: If you buy the bare drive and you are using a laptop YOU WILL NEED A USB TO SATA ADAPTER! I used Uspeed USB 3.0 & eSATA to SATA External Hard Drive Docking Station for 2.5 or 3.5in HDD, SSD [UASP and 4TB Support] and it worked fine.
OVERALL it has made a speed improvement for me and I find using my laptop (which is a couple of years old) more enjoyable. I hope you have found this review helpful!

Massive Upgrade to MacBookSept. 3 2013
- Published on Amazon.com
I have a late 2009 MacBook (the white polycarbonate one). It was performing unbearably slowly-- app switching and launching, booting, and even shutting down frequently took minutes. Scrolling in any app that accesses a lot of data (Evernote, even 1Password) was often very laggy. This was true even when I had large amounts of free/inactive memory. It was very frustrating, and I was almost ready to buy a new computer. However, I could see very high disk activity in the Activity Monitor during the slow periods and figured the bottleneck was probably my hard drive... so I went ahead and bought the Samsung 840 Evo and upgraded my RAM to 8 GB (Crucial 8 GB Kit (4 GB x 2) DDR3 1066 MT/s (PC3-8500) CL7 SODIMM 204-Pin for Mac (CT2C4G3S1067M )). Best computer decision of my life; the performance problems evaporated when I put in the Evo and the new RAM. Apps launch in seconds, no laggy scrolling, and I haven't hit the limit in terms of the numbers of things I can have open at once. Highly recommended.
P.S. Make sure you have an appropriate screwdriver (Wiha 96100 Phillips Screwdriver with Precision Handle, 00 x 40mm) and either a USB to SATA cable or a 2.5" hard drive enclosure. The screwdriver is needed to remove the bottom of the MacBook and to release the hard drive; the cable or enclosure is needed to connect the drive to your computer so you can clone your current drive before making the switch. Other screwdrivers might also work. Some articles I read suggested that a "T6" screwdriver was needed, but it wasn't for my MacBook model; can't speak about others.

My second SSD from Samung! My first was a Samsung 830 Pro, now 840 EVO? What is the difference? Explained.Nov. 22 2013
- Published on Amazon.com
I previously have owned a Samsung 830 Pro which is the model below the 840 series and it has performed great for over 2 years now! I am building a new PC and bought two Samsung 840 EVO because I had a great experience from my previous buy. To those wondering what the difference is between "Pro" and "EVO" The pro uses a different type of NAND. The Pro uses MLC which is older but faster. The EVO uses TLC which is newer and cheaper to produce. This means the 840 Pro has an estimated lifetime of 60 yrs vs. EVO with 19.
TLDR: Unless you plan on using an SSD for over a decade or you want the very top end specs money can buy (professional level) the EVO will be a great SSD.

Smoke'in Fast 1TB SSD DriveDec 22 2013
- Published on Amazon.com
I just added the Samsung 840 EVO 1TB SSD as the boot drive to a fairly complex system and I must say went very smoothly. This review is for putting the EVO in a Desktop/Tower PC(not a laptop) as the boot/OS drive or C: to most people...
High Level Review:
Pros: - Very easy with fairly new systems running Win7 (32 or 64 bit) - Very fast drive compared to a hard disk and pretty good even up against other SSD's - Samsung Migration Tool (will work for most systems) - Samsung Magician Tool -- This is the best SSD maintenance and support tool I have ever seen and very easy to use
Cons: - You must supply your own SATA to USB 2/3 adaptor and cable (they are around 20 - 30 bucks here on Amazon) - You must supply a 2.5" drive bay adaptor is your PC does not have 2.5" bays (most are 5.25") - It will not copy Recovery Partitions (you will have to make a DVD or give it up which I would not suggest) - USB 2 to copy a large system (say 500GB+) could take days
You might say there are three big parts to migrating to the EVO, migrating your OS to the SSD, physically installing the SSD in your PC, and post install tuning / maintenance with the provided Samsung SSD Magician Tool.
The first part, migrating your OS is not tricky with the Samsung Migration Tools, however this is just the bare drive, you need a SATA to USB adaptor, they run 20 - 30 bucks here on Amazon, if you are buying one, then spend the extra and get a USB 3 version, it will be well worth it and could shave many hours off of the migration time. Because I had more than 2 partitions could not use the Samsung migration tool and instead use the migration tool in Paragon Hard Disk Manager, something I already had.
Part two is after the tools tells you it was successful in migrating your OS drive to the SSD. Now you will need to open your PC and find the boot drive and remove the data and power cables. If you are not going to use the old had disk, remove it and install a 5.25" to 2.5" drive bay adaptor so you can properly mount the drive in a bay. You can get the bay adaptor here on Amazon for 8 bucks and you want to use something to secure the drive in the PC for good grounding and to draw off heat. This is not really very "complex" hard but depending on your PC might be a little time consuming. The cables are idiot proof, they only fit in the spot they go in and only the right way.
The final part, if your start up is successful, once you stop laughing at how insanely fast it just booted and if you installed the Samsung tools, the Samsung Magician comes up and you can see how fast your new disk is and follow their recommendations on the settings except the AHCI setting.
This is an all or nothing deal, if anything goes wrong at any point you have to start over, this is to ensure you get a rock solid system and not find out a week later it missed something.
When you go into the performance section of Magician it will have a warning that your SSD could be faster if you change your BIOS from RAID or IDE to AHCI -- Don't believe it, why Samsung sabotages are perfectly smooth effort is beyond me even if it marginally true.
If none of acronyms those meant anything to you then you should just ignore the message, your SSD is not going to go any faster, at least not that you will notice, changing your BIOS from IDE or RAID to AHCI will literally result for 99% of folks with a PC that Blue Screens on the next reboot right after the Windows logo finishes. (hangs) This is because the OS will not have the right disk drivers loaded and thus will think there is no bootable drive installed. But wait it gets worse, for say 25% of that 99%, changing this setting will corrupt all drives attached to that controller. I benchmarked the EVO in RAID and AHCI and it was roughly a tie.
You will love the new performance, my boot went from 3 min 22 sec to 44 secs, program loading is near instant as well as files, everything just blazes, search email or the disk and it just jumps back at you before your finger is off enter key or the mouse button. My PC Experience Mark went to 7.4 Overall and 7.7 on the OS disk (out of 7.9) from 5.9. Everything that uses C:, it will get faster unless it was already too fast to tell.
I would easily recommend this to a friend and plan to get a second one to replace another drive in my system.
That is it and now the fun Stuff:
PC Cold Boot HDD: 3 Min 22 Sec PC Cold Boot SSD: 44 Sec PC Warm Boot HDD: 2 Min 50 Sec PC Warm Boot SSD: 38 Sec
PC Experience Mark HDD: 5.9 PC Experience Mark SSD: 7.4 out of 7.9 -- The SSD scored a 7.7, my graphics card came in at 7.4
Full System Backup (Smart Image) HDD: 3 Hours 50 Minutes Full System Backup (Smart Image) SSD: 48 Minutes
System: HP Pavilion i7-990 3.46GHz CPU / 24GB RAM / GTX 660 Video card / Samsung 1TB SSD / Ceton Quad Tuner Card / eSATA / USB 3 / StarTech USB 3 Dock / Win7 Ultimate 64-Bit / Paragon Hard Disk Manager Pro '14 (I used my usual disk management package to migrate)
