Samsung 840 EVO Pro SSD

The Ideal Choice for Solid Performance and Reliability

High productivity is one of the most valued assets in any organisation. However, keeping productivity at an optimal level, while managing data securely, is a continual challenge for IT professionals and corporations. For large enterprises and tech enthusiasts planning to upgrade their servers, Samsung’s SSD 840 PRO is the solution. The 840 PRO is fast and reliable -- an ideal choice for professionals looking to supercharge their workflow.

Unrivaled High Performance

The Samsung SSD 840 Pro is a high-performance SSD designed for IT professionals and tech enthusiast. Capable of delivering fast read speeds of up to 100,000 IOPS random and 540 MB per second sequential, the 840 PRO is the ultimate in power computing, offering superior performance when it matters the most. Sophisticated performance-enhancing features deliver consistent speed for demanding applications under heavy workloads.

Ultimate Reliability

Samsung’s SSD ensures solid reliability and high performance over time and under heavy use. Samsung SSDs are designed completely in-house for quality-control assurance. Furthermore, Samsung manufactures all of the main SSD components itself.

Longer Battery Life

Samsung has made major strides in power efficiency. It boasts the lowest idle power consumption of any SSD, an extremely important achievement considering that SSDs spend the vast majority of their time sitting idle. In fact, Samsung’s MDX controller consumes only 40 mwatt of power during idle mode -- half that of its predecessor and up to 97% less than other SSD controllers. Further improvements come from the use of LPDDR2 cache memory, which offers higher performance while consuming 30% less power when active and 93% less power when idle than regular DDR2 or DDR3 memory. All of these advantages result in an improvement of up to 30 minutes in battery life over previous-generation models, letting employees get even more out of their mobile work environments.

An extended battery life helps employees provide a smooth customer services and uninterrupted presentation without need for battery recharge, creating better services and a good impression to clients.

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.

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.

It's also the first solid state drive I've ever owned, but I've seen quite a few in action and this is by far the best.

You know that box that used to show up whenever you copied or deleted files? The one with the progress bar and the 'time remaining' ticker? Well I catch glimpses of its outline every now and again, as it pops up for a fraction of a second, but I've almost forgotten what it looks like. I only see it when I'm copying files larger than 500MB or so from this drive to the HDD that serves as a storage drive, and even then that's only because it's being limited by the write speed of the HDD. All in all, you'll not have a speedier experience.

For games, I did a little test on loading times, and in every case they were cut buy at least a half. Assassins' Creed III was slashed from 24 seconds down to 4. That's a reduction of about 88%. Loading times aren't the most important use of an SSD but they're certainly a huge plus.

As for startup times, it's getting to the point where I have to sit down and get comfortable BEFORE I turn on the computer, because otherwise the thing's up and running before I've had a chance to adjust my chair. Most times Windows 7 doesn't even have a chance to finish its startup logo, and you barely see a flash of the welcome screen before you're at the desktop, ready to go. My friend has an Agility 3 SSD and it takes at least twice as long to get that far.

Now it's come down by about £50, with prices at about £170 (edit - one year later and it's now more like £130-140 - can't go wrong with that) across the board, this is looking more and more like THE ~256GB SSD.

At the time of writing the Samsung 840 Pro is the best SSD available on the market. It is the reference against which all other SSDs are measured. If you're still reading, then you either need more convincing or you want some more info.

I switched my laptop from a regular hard disk to an SSD as soon as the prices of 250/256GB models dropped to "reasonable" money. I have not regretted it. In fact, after migrating my system to the SSD, I kept my old hard disk as a system backup. I recently had to go back to this backup after my Windows was corrupted after a crash (thanks Symantec, you're standards continue to underwhelm me). Boy was it slooowwww! Booting off of an SSD is not "instant on" fast (I had been hopeful before getting one), but it is measured in seconds rather than the minutes of my old hard disk (a 7200rpm Seagate Momentus).

As for the Samsung 840 Pro, I find it hard to believe, but upgrading from a 256GB Samsung 830 SSD to the 840 Pro feels faster. In fact SSDs are getting close to the limits of the 6gbps bus, so waiting around for higher performance models right now is just not worth it.

On top of that the lifespan of the Pro model is quoted at 5 years, whereas the non-pro SSDs are rated at 3 years. This is a significant increase for a small price difference.

If you're not aware of this, the memory used in SSD drives can only support a certain number of write cycles (where new data is written to a bit of memory). The more you change the contents of the drive, the faster it wears out (this is why you should NEVER defragment an SSD - you are subjecting it to a lot of write accesses and you're not increasing performance. Disk based HDs lose performance as files fragment because they have moving parts, SSDs don't.

Size Name: 128 GB Vine Customer Review of Free Product ( What's this? )
I replaced my crucial m4 with this SSD. So far I'm impressed. Everything works great, it's really fast. The design is excellent; it's a shame that we have to put this inside the case. This drive does come with samsung magician software (optional install). It's a good addition to the drive as it shows you if there are any firmware updates, shows you the health of the drive & helps you optimize your system for use with an SSD.

A lot of people only look at the speed advertised when it comes to SSDs but IOPS (Input/Output Operations Per Second) are also important. It' self-explanatory, the more IOPS the more operations can be performed within a second. This drive combines great speed (almost maxing out sata 3 capabilities) with great IOPS, Samsung uses their own controller, which is similar to the one used by crucial. It doesn't need to compress any data therefore you should get great performance from it all the time, not only when it's able to compress data (like sandforce controllers which I wouldn't recommend).

Honestly, this is currently the best drive on the market for sata 3 connectivity. Yes you can get the 256GB and 512GB which have slightly better performance however you will most likely not notice the difference therefore I would not recommend the larger drives unless you really need the extra space. That's all I can say at this time, I can't wait to see if the performance will be affected a couple of months down the line, but so far so good.

btw here are the performance stats:

Sequential Read Speed: Up to 530MB/s
Sequential Write Speed: Up to 390MB/s
Random Read Speed: Up to 97K IOPS
Random Write Speed: Up to 90K IOPS
