Customer Reviews of Samsung 840 Pro 512GB 2.5" SATA III Solid State Drive (SSD)
Great upgrade to boost performance on an older laptop.
Best SSD in the market for this price1/27/2014
Best performance SSD in the market for this price. Have used this drive on Dells, Lenovos and HP laptops with no problems. And with the Samsung Magician software, the performance is increased exponentially. Glad I purchased these SSD's.
We have tried several different SSDs. These are the most reliable. Highly recommended.
Samsung 840 Pro 512GB12/7/2013
This is one of the best SSD's available. Samsung is a real leader in performance, I just wish they came in much larger storage sizes. I use one of these as my boot-drive and another in an external USB 3.0 device and both have performed like champs since day one. I have 20TB of internal/external available disc space and of course, these SSD's are the fastest.
Work like a charm. Fast read/write. Aluminium casting, solid construct. Will buy again.
The best there is8/2/2013
Samsung has always been a top of the line brand for many years now. Once they broke into the SSD business everything changed. Offering one of the top SSD platforms at relatively lower prices than most companies, Samsung continues to be a leader in reliability and innovation. The 5yr warranty is nice to boot, and the reason I got the pro version over the regular.
A great SSD7/27/2013
I received this drive in great condition.I put it in my computer went to disk management and set everything up to install Windows 8. After that I tried to clone the drive using cloning program I had used before but that didn't work, wouldn't boot after copying. tried several times, no success. I thought it was the drive. Before sending it back I decided to use a mirror Image I have set up from my cloud backup program that keeps a mirror copy every day. imaged it and it works. Fast drive.
Excellent SSD manufactured by Samsung.7/23/2013
Product delivered quickly and was just as advertised. Awesome product that was very easy to install.
Definitely not the cheapest SSD in this category but performance in both read and write is amazing. Had no problem using the cloning software from Samsung's website to upgrade my laptop's HDD. Recommended.
this is one of the best SSD's you can get on the market
Was really happy with the condition/shipping of the product and the SSD itself screams in my 2011 MacBook Pro. I used an OWC Data Doubler to make this my primary drive and my old hard drive a data drive (took out the optical drive to use as an external). Had no trouble installing and transferring my data over. Enabled TRIM and it's running great, faster startups and I can even run games in Steam under Parallels which I couldn't do with my old slower drive. Was able to get this on sale + tons of Rakuten points over Memorial Day weekend, seems a bit overpriced currently, but it's a great drive.
Best SSD you can buy currently7/17/2013
Basically the standard which other SSDs are compared against currently. Don't confuse with the lower endurance non-Pro version.
The item was quickly shipped. Item was placed in reasonable size box and arrived without damage.
One from the bests sellers - very happy7/3/2013
One from the bests sellers - very happy
Currently the most reliable and powerful drive.
Works great in my 2012 MacBook Pro - purchased this and installed it myself rather than buy an SSD upgrade from Apple. All I needed was a #00 Phillips head screwdriver and a T6 Torx screwdriver. Was able to easily format the drive at startup and use Internet Recovery to install OS X. The computer starts in less than 10 seconds and apps launch instantaneously.
The quick boot and super fast load of applications is amazing.
Great deal on a fantastic drive4/17/2013
I got this SSD to replace the HD in my Macbook Pro, and I could not be happier. It is fast - so fast! Previously my 5400rpm drive read and wrote at about 80mb/s. Now: in the 500s! Lightweight, no problems and plenty of space for all my applications.
