I've been running one of these for several months now and it has been great, very fast, no issues. Install was breeze and this outperformed my previous SATAII SSD by A LOT. Boot times are shorter, there is no lag waiting for a disk to spin-up, no noise, no heat... no complaints :) The fact you can drop one these in a laptop and get this kind of performance while improving your battery life is great. Samsung has the newer EVO line, not quite as fast but a better price point to consider.
This is a Powerhouse SSD1/30/2014
I spent about a month researching SSDs and most reviews pointed to the Samsung 840 Pro being the best. I'll tell you that I agree. This was the simplest hard drive install I've experienced. Then add the improved speed over my Western Digital 7200 rpm drive, there is no comparison. Most reviews said that you would only notice a slight difference in boot up speed and application speed going from a standard HD to a SSD. I personally notice a huge reduction in the time it takes.
Nice- Works fine! Difficulty figuring out the ins1/23/2014
This is my first SSD, so I was not sure how to install it in this new computer I was building. The instructuctions were just pictures - not English text. I had a problem figuring out the software as a result and would have never done it right except I bought a second one for an old computer. The software worked right in that computer, so I finally figured out how to use it in this new computer. Bottom line I got it working and it is all good. Be careful with the screw-in holes - they are delicate!!
Samsung 840 Pro Purchase1/21/2014
Product works perfectly. Completely satisfied.
pretty darn good12/8/2013
went from intel 80g to ocz 120g to this. capacity is really nice and usable at this spot and performance is a little better, though not really noticeable in real-world usage. great packaging, great looking piece of hw.
One of the Fastest Sata 3 SSD11/21/2013
This drives is very fast and as far as the size goes it's perfect for a boot drive with the ability to store many games. Remember load time will be reduced dramatically with this drive so you will be playing asap instead of staring at a loading page. Definitely worth the money!!!
Samsung 840 Pro SSD9/7/2013
Reliable and well performing SSDs for mid-range performance.
Very fast writing and reading speed. Hope the reliability will be good as well
Instalation not completed8/24/2013
Unfortunatly I got a virus on my computer an not installed the SSD yet.
Nice speedy SSD8/22/2013
if you are in the market for an SSD, the Samsung 840 is the way to go. Very good component.
Best SSD I've ever owned8/21/2013
I wanted to do a few upgrades on my mid-2010 Macbook Pro so I went with 2 Samsung 840 Pro 256GB SSD drives with a RAID 0 config. The speed is crazy fast, compared to the old 500 GB 5400rpm HD. Its also dead quiet and doesn't feel burning hot like the other drive. I just wished it was a little cheaper.
This SSD is absolutely amazing!8/20/2013
I replaced an older OCZ Aigility 4, which went into my laptop, with this drive. Similar read speeds to the OCZ, but dramatically improved write speeds (>400 Mb/s). 5 stars easy. If you haven't upgraded to an SSD, even on an older machine, do yourself the favor. Easily the best upgrade to any machine, noticeable difference in almost every facet of computer use.
Right on Schedule8/13/2013
Turnaround was prompt and my order arrived right on schedule. No problems!
No problems with the install. Have other Samsung SSds and they are still working just fine. Looking forward to years of problem free use.
researched many drives and this one is the best bang for the buck
Samsung’s SSD 840 PRO Series is capable of delivering up to 540MB/s and 450MB/s of sequential read and write speeds for ultra-fast file transfers—including random speeds of up to 100K IOPS for the fastest real-world performance.* The SSD 840 PRO Series provides workstation-class performance for seamless video editing or the ultimate gaming experience.
samsung 840 pro8/6/2013
I have had a lot of trouble with Intel SSD's lately so I switched and now have 3 Samsung 840 pros. These SSD's are very fast and they were no trouble installing or operating. An old Intel SSD would not work with windows 8 and I kept thinking that it was a windows 8 problem. I finally put the Samsung 840 pro in and my computer works perfectly with windows 8.
Fast, light, thin!8/5/2013
This is the best SSD in the market right now. I placed it into my Dell 15R SE with i7 and installed a fresh Win7 Pro. Booting time is under 20s. Pretty impressive given the fact that Win 7 has to use legacy boot vs. UEFI boot in Win 8. Every app loads instantly. It's really quiet, too. Magician software is good for managing this SSD as well as firmware update. Price is still a bit high but you get what you paid for, of course. I used Intel and OCZ SSDs before but this Samsung one is the best. Everyone wants it! 5 year warranty is important because the OCZ drive failed on me. Go for it if you can afford the price. You won't be disappointed!
excellent ssd that by Samsung, the best in the market at the moment
I bought this for a friend so he could do a fresh install of win8 on a 4 year old computer. Wow. I think it took less than 20 minutes to install, everything is instantaneous and really makes you want actually use your computer because we all know delays are frustrating!
Best SSD hands down8/2/2013
The speeds on this ssd are insane, loading windows 8 on got partition mode in less than a second, thats how quick it is, a blink of an eye. this ssd is on the procey side, but the components samsung used ensure its reliability and strength, things you cant live without. buy if you can find this around $180.
Super fast and Reliable8/1/2013
I had different SSDs and I thing 840 pro is the fastest and the most reliable one!
Really helpful to make my computer to start-up much much more faster than regular hard drive. It worth the price!!! I really enjoy the decision I have made for it. Thanks for Rakuten, I like this SSD...........Great to have one for you too. The installation is really easy and fast to go.
If you want one of the fastest get this7/25/2013
Have 2 of these drives, one for a laptop and another for a desktop. Both computers boot windows 7 and 8 in around 8 seconds from post screen. If your looking for speed its a given for this SSD, it still one of the fastest in any hardware review site. The first of these drives I purchased 8 months ago still runs perfectly, I would say its reliable to. Tom's hardware "Best SSD for July" says this is the one to get a this price point. Almost a year when it was first release.
This has really helped the performance of my laptop.
great price for the product and timely delivery - totally satisfied
The hard drive has done everything I'd read about in reviews (Google the reviews) and the only thing that was holding me back was the price. When it went on sale I'd already been pricing it so I knew it was a great deal. It arrived quickly and I had no trouble migrating my data using the included migration software. I would recommend
I bought this drive under rakuten promotion program. Always trusted samsung as brand and couldn't resist rakuten offer. It came from beachcamera just in time as stated and works perfect. My laptop's boot time dropped from 2 minutes to 15 seconds. Opening documents and presentations is charm now. I am glad I bought this drive.
Perfect item with cheapest price and I am very satisfied of it!
SSD's change everything7/2/2013
This is the single biggest improvement you can make to a computer if you are still using a rotary hard drive. Highly recommend.
Bought this to help saving my old AMD dual core desktop computer. Very easy to install and the performance is very impressive to use as the OS drive, compared with the SATA 250G Hardisk. Slightly expensive, but it is worthy!
Samsung 840 Pro SSD6/28/2013
It was easy to install and set up using the included software! It is really fast as advertised! So far I am very pleased with the conversion. I put it in a Toshiba 875-S1702 laptop. What a difference an SSD makes.
I am always amazed how much a ssd can speed up a sluggish computer
Best Upgrade for your PC6/21/2013
The Samsung 840 is one of the best upgrades for your current PC or your new build. Windows 8, SATA 3 and a Samsung 840 Pro gives you boot times of less than 8 seconds from cold boot.
Best purchase I could have made6/20/2013
This SSD is blazingly fast and super spacious. I use it for my boot drive and still have a lot of space for programs and games to be installed on it if I want. I do not know how I lived without an SSD before. This thing opens programs in under a second and games load super quickly. On top of that, this drive uses MLC memory so it will last longer than a traditional harddrive and other SSD drives that use TLC memory.
Not quite as fast as expected6/17/2013
I was running out of space on my trusty 160GB Intel X-25M G2 SSD, so I bought this drive to replace it. My laptop has only SATA 2, so this drive cannot quite reach its full performance potential - as reported by Samsung's own performance test utility, while 840 Pro is 4x faster than X-25M for both sequential and random writes, it is only about 25% faster than Intel in both sequential and random reads on my system. On top of that, Samsung's data migration software is a joke - instead of booting off of a CD or USB thumb drive, it wants to copy system partition from under running Windows - and skips any files that are locked. Meh.
The item was shipped and arrived on time. It was also competitively priced over other vendors.
The 840 Pro made my Y580 fly!!!!
Fast, reliable and the value is incredible!
Solid drive. This thing is fast, small, saves power and boosted my macbook pro to new levels of speed considering its a 2006 model. Get this drive at this size and get another internal harddrive for your crap and just load all your apps on it because you will have plenty of room
Fast SSD Drive6/14/2013
Very solid drive. We have 3 of these now. We use one for a server and it has dramatically increased our boot time. The other two were for a video capture device and it has been working great.
Samsung clone software worked great
fast like flying... A++
Can't wait to test this drive out.
Samsung 840 Pro 256GB 2.5" SATA III Solid State Dr6/11/2013
The performance of this SSD is great, highly recommended!
Samsung 840 Pro = Fast!6/11/2013
Works like any piece of hardware should...it just does. Once you go SSD, you'll wonder why you put up with mechanical drives for so long. I haven't had the time to run any official benchmarks, but it's clear that the performance difference from my 300GB Velociraptor is night and day. I'm only running SATA II and everything is instant. It would have been nice to see an included 3 1/2" bracket, but I knew this going in.
Great to work with6/11/2013
samsung 840 pro for macbook pro 15 mid 20126/11/2013
I wanted to have a dual drive setup for my macbook pro since I do not use the superdrive. Installation was easy (840 pro in the original hdd space, old 500gb hdd put into a caddy in the optical drive slot.) Installation took about 30 mins, used Super Duper to clone hdd to ssd (since CCC now cost money) and it all works wonders now. OS is fast and the ssd has enough space to hold my everyday files.
Samsung 840 Pro6/11/2013
Very fast SSD. Installation was made easy with included software for transferring image/files from old HD. You'll like the speed of this SSD. Great results.
