Samsung 850 EVO PRO 2.5 inch Solid State Drive
The Samsung 850 PRO SSD redefines storage with the drive based on 3D VNAND flash, offering enhanced read/write performance, reliability and power management efficiency. The 850 PRO delivers up to 2x the speed, density and endurance of conventional flash.
|
|
|
|
|
|---|---|---|---|
V-NANDSamsung's flash memory is fabricated using an innovative 3D V-NAND architecture, which stacks 32 cell layers on top of one another. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND. |
Ultimate Read/Write PerformancePowered by Samsung's cutting-edge 3D V-NAND technology, the NAND flash memory delivers class-leading read and write performance for both sequential and random workloads. |
EnduranceWith twice the endurance of the previous model*, the 850 PRO will keep working as long as you do. Samsung's V-NAND technology is built to handle a minimum of 150 Terabytes Written (TBW) over the lifetime of the drive, which equates to a 40 GB daily read/write workload over a 10-year period. Plus, it comes with the industry's top-level ten-year limited warranty. *840 PRO: 73 TBW > 850 PRO: 150 TBW |
Efficient Power ManagementThe efficient design of the 850 PRO enables you work longer and more productively. Boasting the lowest power consumption of any SSD when in standby or full use, the 850 PRO uses less energy while maintaining class-leading performance. The 850 PRO fully supports Device Sleep mode for Ultrabook, consuming only 2 milliwats (2mw) of power in its ultra low power state. Plus, its low power DDR2 cache memory provides high performance while consuming up to 30 percent less power when active and up to 93 percent less power when idle than typical DDR2 or DDR3 memory. |

Extended Data SecurityProtect your PCs hardware and personal data when you take your laptop on the road with the 850 PRO's Self-Encrypting Drive (SED) technology. The drive includes an AES-256-bit hardware-based, full disk encryption engine that secures your data without the performance loss often experienced with software-based encryption. The 850 PRO's advanced security complies with the TCG Opal v2.0 standard and is compatible with the Microsoft eDrive IEEE 1667 protocol. Plus, you can quicklyerase data or sanitize your drive with the crypto erase feature. |
Dynamic Thermal Guard ProtectionThe 850 PRO includes Dynamic Thermal Guard protection, which sustains performance while minimizing the risk of overheating. This feature monitors and maintains the drive's optimal operating temperature with a throttle feature that automatically drops the SSD's temperature to protect your data while ensuring the responsiveness you expect. |
Enhanced RAPID ModeYou can kick up the read/write performance when you need it with Samsung RAPID mode. Just like shifting gears in a car, Magician software gives you the option to enhance performance by processing data using unused PC memory (DRAM) as a cache, providing 1.8 times faster performance in the RAPID mode*. * PCMark Vantage score (512 GB): 53K vs/ 97K(in RAPID mode) |
End-to-end Integration SolutionThe Samsung 850 PRO uses 100% Samsung designed and manufactured components. 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 perfectly together. The result – enhanced performance, lower power consumption with the Samsung LPDDR2 DRAM cache memory and improved energy-efficiency with the Samsung 3-core MEX controller. |

My PC is a tad old, but with a good spec- and until now, had been using 6 hard drives(physical) with a Velociraptor 150 GB HLFS driv as my boot drive.
Spec of the original PC
---------------------------------
-- CPU: Intel I7 920
-- RAM: 12GB Corsair
-- Hard drives: 6. Comprising of Western Digitial and Seagate; iincluding 3 AV drives for my video and audio collection
-- Graphics : NVIdia 610
-- O/S: Windows 7
I then finally got to a point in life where SSD and its associated costs became a viable proposition..
Since Installing this 750 Evo... my PC has gone to cloud 9!
With 12 GB of RAM to go with it, and with the Samsung Magician installed... everything seems to be cached and what used to take 2 seconds, now (for most part)... take 0.5 seconds ; or a Windows 7 boot up (cold) that used to take up to 75 seconds, now happens in less than 10!!
All my Windows Media player music /MP3s too are readily available, when I switch between playlists(I have over 25,000 tracks!).
All in all, as a software engineer and video/music lover, I'm in cloud 9 - based on my PC's Performance gain!
Thanks Samsung, for your as-always-impressive products!
Very happy customer here! :)
My C: drive was a Western Digital Raptor, quite fast for a hard disk but very very noisy and continually needed defragging.
I decided on the EVO as the performance difference to the PRO was not that important for me, I needed to work with a quiet machine.
Performance was 1m:30s to boot to desktop before installation, 30 seconds with the SSD installed. I do have some cache on other hard disks a few seconds could be saved without this I guess.
Please note that the SSD comes with no screws, no SSD holder and no USB cloning cable. I had a Crucial SSD cable and the tiny screws came with my PC case. These little screws a difficult to source, I would hope they come with an SSD holder if you need to order one, so be aware!
INSTALLATION:
- Don't use the CD which comes in the SSD box, it is most likely out of date and may not support Windows 10, my CD was V4.5 and V4.9 is the most recent. You could end up in all sorts of trouble using the CD.
- Sign-in to your computer with Administrator rights.
- If you have migrated to Windows 10 you may consider removing Windows.old on the C: drive
- Tidy up the old disk by removing unwanted programs and temp files, as a precaution I also prevented the C: drive being optimised at this time.
- Download Samsung Data Migration Software from the Samsung website, being careful not to download from a download site.
This software clones your hard disk to the SSD.
- Download Samsung Magician Software for PC; or MAC of course,
Magician software should reside on your computer it is used to optimise the computer and checks/downloads the firmware version.
- Insert the SSD into the USB cable device.
- Run the Samsung Data Migration Software to clone the hard disk by following the instructions.
- Switch off your computer and remove the power cable.
- You can next remove the old hard disk and install the SSD, don't touch the contacts!
- Turn on your computer, install and run the Magician software and optimise to your requirements and check for firmware updates.
Then run a performance check, mine is Read 535 / Write 508 Mbit/s
If you have a laptop with no encryption program such as BitLocker then encrypt the SSD.
- Sign back into your computer with Standard rights, Administrator privilege is a high security risk.
- Enjoy the new speed and quietness.
Tip! There are programs which TRIM SSD cards, according to Samsung TRIM is automatically built into Windows 8 and above so don't do this.
Hyper-V. if you are running Hyper-V then it may not start, ignore any messages about BIOS and do this:
- open the Windows Command prompt as Adminitrator
- enter this command
bcdedit /set {current} hypervisorlaunchtype auto
- reboot and it works.
BTW- these drives are only 7mm deep instead of the older 2.5"standard of 11mm, so if you're installing one in a caddy of any sort, bear in mind that you might need a little packing to stop it rattling.
