Samsung 840 EVO SSD

Enjoy High Performance

The Samsung SSD 840 EVO is a high-performance SSD designed for power users. Capable of delivering up to 98,000 IOPS Random Read Speed and 540MB/s Sequential Read speed, it is an SSD of unrivaled high performance. Even better, the advanced MEX controller delivers these speeds regardless of data type, unlike some competing controllers that greatly favour compressible data.

Boost your write speed with Samsung TurboWrite technology.
Switch to a higher gear
Magician software gives you the option of RAPID mode.
Always be in High Acceleration

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

Switch to a High Gear for Rapid Performance

Like changing gears in a car, with Magician software you have the option of RAPID mode, enhancing performance by processing data on a system level through the use of free PC memory (DRAM) as a cache. Depending on your PC memory, you can expect high performance and more efficient command processing, which improves with repeated tasking.

Keep your data safe
Self Encrypting Drive (SED) security technology helps keep your data safe.
Dynamic Thermal Guard protection
Dynamic Thermal Guard protection monitors the temperature of your SSD.
Consistent Reliability

Shocks, vibrations, high temperatures -- bring it on. Equipped with Advanced Signal Processing, Samsung SSD 840 EVO automatically corrects errors so you'll worry less about your data's stability. Plus, using Samsung Self-Monitoring Analysis and Reporting Technology (SMART), you can track your SSD's health status. SMART warns you of any unforeseen errors before they occur, so you'll be prepared.

Samsung's Dynamic Thermal Guard protection monitors the temperature of the SSD, preventing it from overheating. When the SSD is exposed to extreme temperatures, the algorithm controls the SSD's power supply to keep it cool. Plus, with Samsung SSD 840 EVO your PC becomes lighter, meaning you can carry it around with you.

Add style to your PC.
Rock-solid Encryption to Secure Your Data

Samsung 840 EVO Self Encrypting Drive (SED) security technology will help keep your data safe at all times. The drive is included an AES 256-bit hardware-based encryption engine to ensure that your personal files remain secure -- even if you lose your laptop.

Energy Efficient

Enjoy doing more of what you love on your computer for longer. Samsung 840 EVO SSD features low idle power consumption. This is important because PCs spend 80 to 90 per cent of their time sitting idle. The drive promotes energy savings and longer battery life.

Simple Tools for an Easy Upgrade

Using a SATA-to-USB 3.0 connector provided in the laptop upgrade package, for a data size of 100 GB, you can migrate all the data from your HDD to 840 EVO in just 24 minutes. The Auto Install guide included in the toolkit will guide you smoothly through the installation process.

Add Style to Your PC

Samsung 840 EVO SSD uses both structural engineering and C-cutting to diamond-cut the premium titan surface, for a sleek and stylish appearance. Watch your PC become reborn with a premium look that expresses its powerful performance.

The Samsung 840 EVO 1TB is definitely a blazing fast SSD. I do feel that SSD drives in general are still slightly overpriced when considering the fact that these are now mainstream, and no longer belonging to a niche market. Yet to be fair, it could still work out as a much cheaper option than buying a new laptop or desktop computer.

The SSD in my review is mounted on a desktop running Windows 7 (64bit), i7 processor with 16GB RAM. My motherboard does not support SATA 3 yet the speed increment is astounding!! Windows 7 actually starts in 7 seconds!!

- Lightning fast drive
- Super easy installation
- Light on batteries (for laptop users)
- "Samsung Magician" software works great for firmware updates and SSD optimization. The software also gives you 4 options: Max Performance/ Max Capacity / Max Reliability / Advanced.
- Macbook Pro compatible. I had issues with other SSD drives, yet I bought a smaller EVO to fit in the macbook and it workes a treat

Prior to mentioning the cons, I would like to point out that these apply to most SSD and not just the Samsung.

- Samsung recommends turning off indexing for reliability. Doing so means that you can no longer search for files from the "Search programs or files". See Photo.

- In order to use the drive to its full potential, AHCI Mode must be enabled in the bios, and motherboard should support SATA 3.
- The 1TB SSD is recommended as one of the features Samsung software offer is Over Provisioning. A part of the SSD itself is used for this option thus decreasing the physical size of the disk. The Magician Software itself says:
Quote "Over Provisioning (OP) optimizes the performance and lifespan of your SSD" unquote.

I have a very old Dell XPS 13 inch laptop, which my wife uses for surfing and emails. The machine was getting so laggy and generally a pain that I thought of getting a cheap second hand one, but a friend mentioned converting to SSD and here I am. I did a lot of investigation into the read/write speeds of various manufacturers (Intel, Samsung, Tosh) and found the 840 EVO the best option for price/write and read speed combination. This may not be the case anymore as this drive was purchased in February 2014.

My drive included some drive clone software which you can use to clone your drive and putting the image directly on, however I decided against this for the following reasons
1 – This would bring any malware/spyware/bloatware with it
2 – It’s easier to copy files you need to a portable drive, do a clean install and thus improve the laptop performance.

IF you’re not a stay at home hedge fund manager, then in my mind there should be nothing on your current HDD that you would want to transfer, aside from mail files (pst etc), music and photo’s. As long as you have a valid license for windows I would recommend a clean install above anything else. (If you don’t have a spare portable USB key, sites like dropbox give you GB’s of storage for nowt). Even for a Dell Laptop which is over 8 years old, I was able to go to dell, give my system tag and re-download all of the drivers I needed.

One thing you MUST remember, this will fit any laptop, but for some smaller models (like my 13” dell), you need a mount for this. The drive has the screw holes for the mount, but no mount or screws. YOU MUST KEEP YOUR OLD DRIVES MOUNT AND SCREWS IF IT HAS ONE!!

*Really easy to install - Just plug (and screw if mounted) and you’re done.

I bought two Samsung 830 SSD's when they first came out. I was so impressed that I bought an 840 PRO when they became available. Two years on & I have consider them to be among my finest-ever purchases. Typically, they are 'fit & forget' drives; the reliability is excellent & the performance is superb. The Magician software allows you to trim (defrag) the drives, & this function on version 4.4 now takes less than 5 seconds. (December 2014: Version 4.5 released).

Three of my drives are 128GB & I used them purely as operating system drives. I installed a separate HDD for storage purposes. Because these drives were so good, I fitted an Icy Dock hot-swap caddy (also reviewed) to my PC & took all of the internal drives out. I loaded my Windows platforms individually onto each drive to give me total flexibility, so all I need to do is power down, eject one operating system & insert the next one.

So far, so good. I had two spare operating systems lying around (Windows 7-64 Premium & Vista), so I bought two 120GB 840 EVO's: one for each platform. For Windows 7 Premium, I just used the Samsung Data Migration software to copy the operating system from a 2.5 inch HDD. It took about 25 minutes & works a treat. I don't see the 7-second boot time that another reviewer achieved, but it's still much quicker. Vista was a new installation, & the SSD transformed what used to be a dog of an operating system into a very decent one.

The EVO's have the 'Rapid Mode' software, & this gives blisteringly fast performance, with some read/write functions being boosted by up to 500%. Of course, Vista doesn't support this feature, but Windows 7 & 8.1 does, so I simply cloned operating systems & I used the EVO's on these platforms, relegating an 830 (which does not support 'rapid' mode) to Vista.
