Samsung 840 PRO Series MZ-7PD256 256GB 2.5-inch SSD

100% Positive Reviews
Rated #3 in SSD


Pros: Fast. Like, really, really fast. Shock and drop damage resistant. Absolutely silent.

Cons: Firmware install can be confusing. Lots of Windows 7 tweaks needed to maximize speed.

I bought my first SSD for my current rig back in October, and let me just say, it is the best investment in this entire rig. It won't give you any more performance in games or demanding programs, but it gives your PC that feeling of quick responsiveness that is lacking in PC's with traditional hard drives. Having this SSD in my home PC has spoiled me to the point that when I use any other PC like the family's desktop, it feels just unnaturally slow.

Coupled with a high-performance CPU and memory kit, Windows 7 can start up in 10 seconds or (usually) less. Games on it can load much faster. On my rig, tested, Left 4 Dead 2 off this SSD can load a singleplayer campaign in 6 seconds. In Skyrim, I had to look up a list of all the tips you get on the loading screens, because I never see them! It's not just games either, Google Chrome launches EXTREMELY quick- It's all ready to browse by the time I release the mouse from its desktop icon!

SSD's are also non-mechanical and will not suffer damage from being dropped, so if you buy this for a laptop, you won't have to worry about smashing your delicate magnetic HDD if you accidentally drop your laptop. Did I mention you'll also see noticeably increased battery life, and it's completely silent?

The downside to this is you must treat your SSD-powered rig a bit differently. SSD's are limited in the number of writes each sector can sustain during its lifetime, so you want to minimize random high-speed writes to the SSD. You may want to store your larger files on a secondary, regular hard drive. There are also several settings you should change to improve its lifespan, such as disabling defragmentation, since fragmented data does not affect SSD performance and this would just be a waste of write cycles. Don't let that "limited write cycles" turn you off though- your SSD would still likely begin to show signs of wear and deterioration about the same time your HDD would suffer a catastrophic mechanical failure.

Bottom line? If you're on the fence about getting an SSD for your next rig, do it. There is no other more rewarding upgrade than an SSD for overall speed of the user interface and loading times. You'll never wait on anything to load ever again.


Pros: Samsung quality, stable high speeds, ultra low power draw, semi-high capacity, low heat, SATA III

Cons: firmware install is a bit iffy

I bought this SSD before Christmas in 2012, the price was a bit higher than other drives of comparable size and I was extremely skeptical of the performance specs that it claimed. However, something occurred to me; Samsung makes their own flash modules, flash memory controllers, and even the case. I felt a lot more secure putting this in my laptop after I realized that Samsung could actually confirm that the memory modules and controller were up to par and completely compatible. So far this little drive has been screaming fast in my ASUS K53SV and it certainly does live up to the performance specs that it sets forth. Being my first SSD, I am more than satisfied and having the SATA III compatibility in my laptop I was happy to actually see a drive that can take advantage of that extra bandwidth. I saved about 45 minutes worth of battery on my laptop as well, which is nice because it sort of offsets the i7s power hungriness. If you purchase this SSD you will not be disappointed, you will be astounded.


Pros: Really fast

Cons: None

This was the fastest SSD I've ever used before. This SSD is in my laptop. I couldn't believe how much faster it is compared to a regular HDD.


Pros: Very Fast, Included Cloning Software, Low Heat

Cons: Price

Samsung really had set the bar high with performance and reliability of their 830 series solid state drives. The 840 Pro takes that bar and raises it up. This SSD is amazingly fast with some very impressive read/write speeds. One pros to buying this SSD is the included cloning software which makes cloning and existing Hard Drive or Solid State Drive a breeze and headache free. Another pro about buying Samsung SSD's is that they are know for their reliability and that provides peace of mind when important data needs to be stored on this solid state drive. The one downside about this SSD is the price. At the time of writing this review, this SSD is going for just below $1 per GB, but there are opportunities through sales to pick this drive up for much less than $1 per GB. Overall for the performance and the reliability, this drive is one of the best choices available right now.
