## Description

Upgrading your PC with a Samsung 840 SSD is the most economical way to breathe new life into an aging PC. The 840 reads, writes and multi-tasks at incredible speeds, enhancing boot-up speed, application loading and multi-tasking performance. It's more than an upgrade, it's a complete transformation of your PC.

Review: Very impressive in many ways... - Things I like about the drive: SPEED: I knew this drive would be faster than my laptop's OEM drive, but not this much faster. My boot time went from over two minutes to less than 20 seconds. Windows shut-down also dropped to about five seconds. But the biggest surprise was the start time of programs like Word, Excel and Outlook - they appear on the screen, ready to use, almost instantaneously. They cold-start as fast or faster than when they were running in the background on my old HDD. POWER USAGE: I have a laptop with infamously short battery life. This drive should give me between 30 minutes to an hour longer battery life. Samsung lists its idle power consumption (and SSDs spend most of their time in idle) at a very low 0.02 watts. This is equal to the 840 Pro and better than the older 830 series which used 0.6 watts. It uses MUCH less power than any mechanical HHD. WEIGHT: This 840 is 3.6 ounces lighter than the laptop HHD it replaced. That may not seem like much, but on a 3 lb notebook 3.6 oz is a huge difference. My laptop went from a 3 pound laptop to a 2.8 lb laptop. INSTALLATION: Absolutely zero problems installing this drive on a Win7 computer. I used Acronis backup software to clone my old drive to the SSD, so I can't comment on Samsung's Magician drive cloning ability. It is necessary to optimize the drive and OS after installing a SSD, and the Magician software made this easy. Changing the computer's OS settings took about ten minutes and improved the drive's performance by about 10% - so don't skip this step no matter how fast the drive seems. One thing I liked about the Magician setup is that not only does it tell you what you should change, it tells you why. The Magician software initialized the SSD automatically during setup, so no issues there. The Magician software also let me know that there was a firmware update available for the drive, and let me install it by clicking a button - very easy. Magician stores bench-marking tests to help identify performance changes over time. Benchmarking can also be used to see how changing your OS settings effect performance. Things I don't like about the drive: Frankly not much. It is 250 GB and not the standard 256 GB, but that wasn't a surprise since it is clearly labelled 250 GB. Also it could be a little cheaper, although its price has dropped to an affordable level lately ($170 at the time of my purchase). It is really a shame it is buried in my laptop because it is so beautifully designed - black with a chrome ring around the edge. With a USB adapter this drive would be a very nice looking external drive. Final comments: I'm very pleased with this drive. You will need an adapter to clone your old drive and I recommend the Anker® Uspeed USB 3.0 to SATA 3ft Converter Adapter Cable which worked very well for me.
Review: Amazing, but not without one glaring flaw... - I purchased this to replace the intel 330 120gb SSD that does not play well with my macintosh because intel doesn't care. It works phenomenally, playing well with my older mac's 1.5gb/s speed limit. It boots up fast, opens programs fast (photoshop and illustrator, WOW). HOWEVER: MY glaring gripe comes with how the drive arrives. I get it in the mail, and hook it up to clone my old intel SSD to this one so i can get RELIABLE ssd performance. My mac "couldn't identify" it, my PC wouldn't show it. My brand new drive showed up NOWHERE. it was only after using Gparted, the liveboot linux based drive partition editor, that I could see the drive. It was completely unallocated. No filesystem, so no computers would pick it up as usable space. What the gosh darn heck kind of way is that to ship a drive. A user of (not to toot my own horn) lesser experience would have no idea to use Gparted and would likely be as angry and frustrated as I initially was. That's no way to ship a drive, as it's literally unusable out of the box and requires more advanced allocation to become usable. So either I got an outlier on ssd style shipping, or samsung has to get it's ssd act together (which is sad to say because they're smart enough to NOT ship these affordable drives with a sandforce controller). This drive is fast. It's nice. the main issue with it is how it, from my view because it came like this to me, is shipped as unallocated space (even the software it came with wouldn't recognize it on my system as it was, again, unallocated). If you're and advanced user who can boot with Gparted and wants an affordable drive with good speed, this is for you, i suppose. Edit: Feb 11th 2013. Someone asked, in response to this review, if it'd fit in a Macbook Air. I'm assuming the original gen because the newest gen has integrated SSD (on the circuit board) to my knowledge. Anyway, I unfortunately do not know. The samsung 840 is absolutely slimmer in profile than laptop HDs and the Intel 330 ssd, but I'm unsure as to it fitting, because I'm unfamiliar with the HD size of those that go in original MB Airs. The real point of this edit is to say something else. A few weeks have gone by since I got this SSD. ZERO freezes like I got with the Intel 330. A huge improvement and step up. Photoshop, Chrome, heck, all my apps launch instant to near instant. It's amazing. It RE-INVIGORATES my computer, it'd undoubtedly do this to any computer, aging or not. I'd like to get another to replace in my Asus UL30vt, which has an Intel 330 SSD, with problems that prevent the laptop from sleeping.

### ⭐⭐⭐⭐⭐ Lightning Quick : Boot times on old XP system reduced from 5 minutes+ to 15-20 seconds, Migration v easy.
*by W***K on March 17, 2013*

I have a very old Pentium 2 machine that I use as a home machine on weekends running Windows XP (from around 2006 I think), with a ton of software, downloads etc, 3 gigs of RAM, an inexpensive Nvidia 210 video card (which, by the way, improved Flight Simulator performance 20 fold compared to running FSim off the motherboard without a graphics card). My home machine used to take forever to boot up - I would literally fire it up, go make coffee, read the paper, and then leave it running all weekend because it took so long to boot up or shut down. Windows Updates also took up to 30 minutes +++ to install. I have upgraded the hard drives a couple of times over the years, but re-installing all the software was a daunting task and real schlepp. (The thought of re-installing Windows and re-sourcing all those programs was a big disincentive to upgrading to Win 7 - particularly as I only use my home machine occasionally - and usually for Word, Excel documents, Flight Planning and for running Flight Sim 2004, X-Plane 9 and FSim X (I am a private pilot and like to brush up on and practice instrument approaches and difficult cross-wind approaches when flying the family into short or difficult bush air-strips. I also have a CH aircraft yoke and pedals attached to the PC by USB.). I also occasional program in Visual Basic and the older operating systems and older versions of Excel have less security hassles. I read the reviews for this 120 Gig Solid State Drive ("SSD") on Amazon and elsewhere, and the Samsung 840 appeared to be the fastest, most user friendly and simple to install and most affordable per gigabyte at the moment. Hence the Amazon Top Seller. This was my first SSD installation. I have installed a number of additional mechanical drives over time (referenced as D:\, E:\, F:\ etc) which is nearly as easy as plugging in a USB drive these days (Google if stuck). Installation of the SSD was as easy as installing another hard drive (in fact - even easier - because I had the Samsung Getting Started Desktop Installation 6 step diagram to follow). My PC now boots up in about 15 - 20 seconds and Windows updates take no time at all - a couple of seconds. The migration (I.e. copying the exact image of my old drive to the new SSD drive) was very easy and took about 30 minutes (I had about 70 gigs of programs on my Old C drive including the Windows XP operating system, Office and hundreds of other small programs and apps that I have accumulated over the years that I migrated onto the SSD - using the Samsung software in a couple of simple steps.. I am still using the same XP operating system , and all of the hundreds of legacy programs , so my PC hasn't changed at all since installing the SSD aside from the lightning quick boot-up. I used the Samsung speed test to test the Input / Output speeds of the Solid State Drive against my old ~2009 mechanical 250gig drive. The SSD is 30 to 50 times faster than my old drive at reading and writing data. I can highly recommend this SSD if you are looking to breathe new life into an old machine, and am going to do this SSD upgrade for all my work and family machines (about 10 machines in total). A couple of pointers: I had already installed a second mechanical drive (D:\ ) into my PC which was and still is used for music, movies, CD image backups, photos etc (You don't necessarily want to migrate these seldom used items onto your SSD) The SSD didn't come with SATA power or data cables to connect the SSD to the motherboard (these are the same SATA cables that the old mechanical drives use). Luckily I had some spare cables lying around. The SSD didn't come with a mounting tray, but because the SSD only weighs a couple of grams, mounting isn't as critical as for the heavy old mechanical drives (although good idea to stow securely - you don't want the drive floating around and getting entangled in your cooling fans). Good idea to have a look at your C: drive (do a search for all files bigger than 10 meg) and remove any programs that you don't use anymore, move your large personal docs, movies, pics, videos, old .iso and .pst (Outlook) files to a separate drive (either a USB drive or a separately mounted old mechanical drive) and clean up your C: drive temporary files before you migrate to SSD (i.e. slim down your C drive before you migrate - so you don't clog up your SSD and waste SSD space). SSD's apparently work better and faster with free space (I have used 70 out of 120 gigs i.e. about 57% of the available SSD space). Use the Samsung software provided on the disk. It is incredibly simple to install and use, and I've read about problems with using other (e.g. Norton or other Acronis) cloning software e.g. "alignment" and resulting speed problems (Google if interested further)
