Product Description
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.
Multi-tasking Multiplied
Windows 8's intuitive Metro UI encourages multi-tasking. Samsung's 840 EVO Pro SSD ensures users will experience great, lag-free performance when working with multiple applications.
Toggle DDR2 NAND Flash Memory
Samsung's Toggle DDR2 NAND flash chips enable data transfer rates of up to 400 megabits per second (Mbps), offering dramatic read speed performance improvements.
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.

After installed immediately run the benchmarks (provided by linux disk utilities): actually 540 MB/s average reading speed, and a ridiculous 0.1 millisecond average *and* maximum access time, completely flat.
My usage is extremely intense and after about one month there is no noticeable degrade. The benchmark still gives the same reading speed, while the access time is a bit more scattered, 0.2 millisecond average, 0.3 maximum, still virtually zero in practice though.
Formatted after one month, in order to refresh the installation of the OS, still no problems and the access time is back as new to 0.1.
I use full disk encryption at the OS level.
From a subjective standpoint, this thing is really fast compared to a normal hard disk of course, I could hardly ask more. It does make the use of the laptop as effortless as possible: opening notoriously heavy programs (Firefox, OpenOffice) is virtually instantaneous, loading heavy tests suites is considerably faster.
In the unlikely case one is still using conventional hard-drives, an SSD is the single most dramatic upgrade that one can make.
The other advantage is that the battery of the laptop lasts a bit more (subjective, but yet clearly noticeable).
As to the built-in HW level encryption it's difficult to say: it is possible to set a password for the HD (in the BIOS) without which it's not even possible to turn the SSD on, but it's not clear if that also implies that the content is encrypted. No info at all in the box or on the samsung website. I would say that this is the only disappointing side of the product.
Now, the only remaining test is the test of time: my system provisioning is entirely automated, and everything is backed up in real time, so even if it suddenly died it wouldn't be a problem. However, I would be pleased if this one lasted at least of couple of years.
A 5-years warranty suggests that it might actually make it.
Update about 5 months later:
My usage profile is extremely intensive.
The perceived performance is unaltered, still very good. The benchmark results are substantially the same, still consistenly 540MB read, with a hard-to-believe 0.1 ms average access time.
Installed this drive as a replacement to the 3.5" solid state drive. WOW! Feels like a new machine.
I have been into IT fo 20 years professionally but still it was a surprise. I am very aware that the iMac is not using this drive to its full potential but I invested a little more into this model so that it can be recycled into something else when the iMac retires in 3 years or so.
For any iMac 2008 users or later . . . . . . here is a shopping list of items that I have used in my upgrade;
4GB RAM modules

NOTE: ignore apple. The 2008 iMac supports 6GB not 4GB tottal RAM. 1 x 4GB slot 1 and 1 x 2GB slot 2.

A torque T4, T6 and T8 screwdrivers are also is also needed.

My iMac now feels like new and for around £100 - £350 depending on your upgrade . . . .wel worth the cost.
I now have plenty RAM, a very Fast 250GB SSD drive (that also increases performance when setup as virtual memory and swap space), 1TB small quiet and fast external drive. My imac is a pleasure to use on everyday graphical tasks. Best of all my storage is upgradable daisy chaining on each enclosure for £50 + drive.
Well chuffed!
I was running a Seagate Barracuda 7000rpm SATA 3 drive before on a Windows 7 machine. The install was about 2 years old so it had slowed down significantly. It was taking a good couple of minutes to get to the login screen, then once logged in it was taking a further 2 or 3 minutes for the desktop to become usable. I used to switch the computer on and go to make a cuppa and then log in and go and use the bathroom. It was so frustrating to use.
I decided to clone my install over to my new SSD so I could have a direct performance comparison. Brand new Windows installs are always blazingly quick, even on conventional hard drives, so I wanted to see if an SSD would be a benefit in the long run.
Boy did it make a difference! My system takes under 30 seconds to boot up (most of this time is taken by the POST screen and the raid status screens on boot, so not the fault of the SSD), once I log in the desktop is useful instantly! It's really made a huge difference. I've recommended it to all of my friends, and the ones that have also bought SSDs are thrilled.
If you have a conventional hard drive it will be the biggest performance bottleneck on your computer. Get an SSD and see your computer fly!
