Samsung 850 PRO 512GB SSD

512GB Samsung 850 PRO SSD

3D V-NAND Flash Memory

Samsung's unique and innovative 3D V-NAND flash memory architecture is a breakthrough in overcoming the density limitations, performance and endurance of today's conventional planar NAND architecture. 3D V-NAND stacks 32 cell layers vertically over one another rather than decreasing cell dimensions and trying to fit itself onto a fixed horizontal space. As a result, the technology provides higher density and better performance utilizing a smaller footprint. The NAND flash memory delivers the ultimate in read and write performance in both sequential and random aspects. This is especially impressive in the 512GB model that outperforms similar models on the market by more than 80 MB/s in write speed.

Samsung 850 EVO - Rapid mode

Rapid Mode

Maximise Your Everyday Computing

On the full range of the 850 PRO you can ramp up the read / write performance using the RAPID MODE. Magician software lets you enhance the performance by processing data on a system level using free PC memory (DRAM) as a cache, providing 1.8x faster performance in the RAPID MODE.

850 EVO Features

Improved Energy Efficiency

Compute Longer with Improved Energy Efficiency

The 850 PRO allows you to work more productively and work harder due to the very efficient, power management components, the 850 PRO 512GB SSD boasts the lowest power consumption of any SSD in full use due to it expending less energy while it maintains market-leading performance. In addition the 850 PRO SSD has LPDDR2 cache memory which provides higher performance while using 30% less power when active and 93% less power when idle than the typical DDR2 or DDR3 memory.

Secure Data - AES 256 Encryption

Secure Valuable Data Using AES 256 Encryption

The 850 PRO SSD protects your PC’s hardware and personal data, the drive includes AES-256-bit hardware-based, full disk encryption engine that secures your data without performance being compromised, that is often the case with software-based encryption. The advanced security in the 850 PRO complies with the TCG™ opal v2.0 standards, protectiong PSID and is also compatible with the Microsoft eDrive IEEE 1667 protocol. Also, you can use the crypto erase service to erase or initialise data.

10 Year Warranty

Guaranteed Endurance and Reliability

The Samsung 850 PRO SSD has twice the endurance of the previous 840 PRO and will keep working as long as you do. Samsung’s V-NAND Technology is built to handle 300 Terabytes Written (TBW) which equates to a 40 GB daily read/write workload over a 10- year period. Plus, it comes with the industry’s top-level limited warranty.

Dynamic Thermal Guard

Protected from Overheating - Dynamic Thermal Guard

Dynamic Thermal Guard protection is included on all 850 PRO SSD’s, it keeps your PC performance safe from overheating, and also monitors and maintains the drive’s optimal operating temperature with a throttle feature that automatically drops the SSD’s temperature where it is necessary to protect your data and ensure the responsiveness you expect.


Level up to the 850 EVO simply without any hassle

Using its One Stop Install Navigator Software, you can migrate all the data and applications from your SSD or HDD to the 850 PRO quickly and easily. The Auto Install guide navigates through the simple three-step process. Plus, you can conveniently monitor, manage and maintain your 850 PRO with the Samsung Magician Software, it features tools to help you maximize performance, including benchmarking, advanced OS optimization, disk health status tracking & over-provisioning (OP) settings.

Top-Quality Components

In-house solution consisting of top-quality components

Samsung is one of the few manufacturers that actually design all the SSD components in-house and has the most experience in the SSD market. Because Samsung has intimate knowledge of every component and its parts, it can fine-tune them at each stage of development to ensure they work together beautifully. The result - enhanced performance, lower power consumption with an up to 1 GB LPDDR2 DRAM cache memory and improved energy-efficiency with the 3-core MEX controller.

The arrival of the solid-state drive (SSD) has revolutionised the speed at which modern PCs perform common tasks. This is because SSDs have no moving parts, compared to larger, bulkier mechanical drives, thus they store information on memory chips. This means that accesses, reads and writes are many, many times faster

Rated 5 out of 5 by from Excellent Excellent SSD. The second one I have bought in a year. Only gripe is that I filled the 512gb in a day. In hindsight I should have saved and bought the 1tb version

Rated 4 out of 5 by from Good product My previous SSD failed so needed a new one. The 850 PRO is used for my boot system and is very quick. The product is good, only issue was the delivery. I live in a block of flats and the delivery guy managed to go to the wrong flat and then said I wasn't in. Had to chase them up and get them to deliver several hours after the original time. Rather annoying as I'd paid extra to have the delivery arrive early in the day; but at least it arrived on the same day after two calls to DPD. Bit early to say much as partly bought the product due to the long warranty. Booting up Windows 10 in a few seconds. Overall a speedy SSD and can't complain.

Rated 4 out of 5 by from A great replacement drive, but beware! I used this drive to replace the one in my Sony Vaio - wanting faster boot-up times and more stability. The cloning function worked first time, though the installation instructions are nowhere near as automatic as implied. Once up and running, though, it took a couple of hours to clone all the data and when I fitted it into my laptop it booted up perfectly, first time. The data rates I'm getting now are a massive improvement. BUT - if you're going to use this to clone an existing drive you're going to need a USB 3.0 to 2.5" SATA III Hard Drive adapter. There's no mention that this is a requirement until you open the instructions and discover that the adapter isn't included. Fine if you know in advance and can order one at the same time, but a pain in the backside otherwise. I'd definitely buy another Samsung SSD.

Rated 4 out of 5 by from Good and speedy God delivery, a bit dissapointed with the speed , but for the price, good value
Date published: 2016-04-12
Rated 5 out of 5 by from Trouble-free migration! I was worried about transferring my OS (Win7) over to the SSD - but it was as sweet as you could wish, not a single snag. I would have wished, however, for a more comprehensive software suite that allowed me to transfer both my OS (on my old "C") and some application software that was running on another disc entirely, all at the same time. I know I can do that now, but together would have been great. Speed-wise, I'm showing RR of 78,000 and RW of 46,000 or so at the moment. I'm pleased I took the plunge!

Rated 5 out of 5 by from Best SSD Around Lightning quick SSD. Have fitted many of these and the EVO model over the last 12 months, and all have been rock solid.

Rated 5 out of 5 by from Quality Product Scan a class act to buy from, good quality at all levels, this product is right up there with the best and Scan as usual delivered the goods!
Date published: 2016-01-01
Rated 3 out of 5 by from Good performance Considering that this SSD rates highly in the "User Benchmark" performance charts, I thought the product was good, and it elevated my PC in User Bbenchmark up to "Aircraft Carrier" vs the Samsung Evo 840 However the Intel 750 Series NVMe PCIe SSD/Solid State Drive 400GB I bought to replace the Samsung Evo 850 pro took my pc with the same software setup (cloned with Acronis) up to UFO - IMPRESSIVE. Buy the Intel 750 Series NVMe PCIe SSD/Solid State Drive 400GB instead of this SSD
