Samsung SSD 850 Pro 2.5 inch SATAIII
The world's first 3D Vertical NAND (V-NAND) SSD- the Samsung SSD 850 Pro
The Samsung 850 PRO SSD redefines storage with the world’s first drive based on 3D VNAND flash, offering exceptional read/write performance, reliability and power management efficiency. The 850 Pro delivers up to 2x the speed, density and endurance of conventional flash. The next leading SSD for performance, endurance and energy efficiency.
What is V-NAND and how does it differ from existing technology?
Samsung'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.
An SSD that won't quit before you do
With 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.
Boost performance with an industry-leading 3D VNAND SSD
Powered 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.
Work longer with high-efficiency innovation
The efficient design of the 850 PRO enables you work longer and more productively. Boasting the lowest power consumption of any SSD when in full use, the 850 PRO uses less energy (need source) 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.
Safeguard precious data without sacrificing performance
Protect 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 quickly erase data or sanitize your drive with the crypto erase feature.
Protect your PC from overheating with Dynamic Thermal Guard protection
The 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.

Seller Warranty Description
Top Customer Reviews
First, I haven't done a controlled performance test of these drives. However, if you check some of the good review sites (like anandtech dot com) and others, you'll find that the tested performance is almost identical. They are both very fine drives, and both have 10-yr warranties, which is a marketing issue, as you're unlikely to be using this in 10 years any way.
At this point, I will continue to buy this one rather than the equivalent Sandisk Extreme Pro. First, it has more space as Samsung allows the entire 512GB to be used, whereas Sandisk only allows 480GB as they are reserving the difference for 'over-provisioning' whereby they have spare sectors to be used when (as happens with all SSD's) sectors fail with use.
More importantly, Samsung's use of V-NAND indicates that the transistors (which are very different and what appears to be a huge leap forward) are more resistant to wear. This is clearly indicated by the fact that Samsung warranties the drive for a lifetime total of 150TB, whereas Sandisk warranties for 80TB. And this is important, as the 10-yr warranty means nothing if you exceed their total.
having said that, techreport dot com is in the midst of a months-log torture test of drives and even the ones to fail first have vastly exceeded the manufacturer's expected limits, in a way that has surprised the heck out of everyone. So the bottom line is that even if 'used hard' as consumer drives, it's unlikely that either one will ever fail to perform well and long.
One nice thing that Samsung has managed with the 850 Pro: Their earlier 830 Pro and 840 Pro were top-notch drives, butt their Achille's heel was their inconsistent performance, though this was more something noticed using test programs than it was something apparent to end users. But the 850 has corrected that.
Also, if it matters to you, this drive supports encryption and the Sandisk doesn't.
Is there anything that would make me select the Sandisk rather than this drive? Perhaps price. Right now, taking into account the usable space for each drive (512GB Samsung vs 480 Sandisk), and the prices as I write this, the Samsung is about 77 cents per GB and the sandisk is about 70. For a 10% difference I'll go with this drive. However, given the huge positive publicity this drive has gotten, I suspect that Sandisk will have to lower prices to keep their Extreme Pro moving, and since both drives are so good, that could sway me.
Once I got home from work today, this was laying in front of my door and I figured that I would begin the process. This was the first time I have ever cloned and switched out a hard drive and it was a breeze - except for the time that it took to clone. For people that are unsure how to this this, I found the following gentlemen on youtube very help with a step by step instructional video, https://www.youtube.com/watch?v=XJHMQlvPEz0. You can download Carbon Copy Cloner for free with a 30 Day trial, which I found very nice that you did not have put in any credit card information or email address.
In order to make the clone, you will need a way to transfer the data from the HDD to SDD. I purchased the Startech USB 3.0 to 2.5" Sata HDD/SDD Cable w/UASP from Amazon - roughly $20.
As far as performance goes, it took roughly 1 minute 49 seconds with the 4gb's of ram and the old HDD to startup and get me to the home screen. After upgrading to 8gb's of ram and the SDD, it takes approximately 40 seconds now - cutting the time by well more than half. Applications load much faster now that it's a night and day difference. I would recommend upgrading to the max amount of memory and a SDD if you have an aging Macbook.
I am not going to go back and proofread my review before posting, so please do not call me out for misspellings or in correcting grammar. I am only trying to offer advice to people that are looking for it. P.S. I am a newbie with computer components. If I can do it, feel confident that you can do it.
So why am I giving it only 2 stars?
Because at only 10 months of use, the drive is starting to fail. I've attached a screenshot of the S.M.A.R.T data, which shows multiple hard failures. The direct impact is that one of the virtual machines I'd created on that laptop is no longer usable. I've determined which extent of the VM is bad, though, and renamed it. I'm fortunate that I've been able to restore an earlier version of the VM; it's back in business, but my faith in Samsung is shaken.
I'm especially concerned because I just spent $800+ on the 2TB version of this drive for a new laptop, and I'm faced with the uncertainty that I'll have similar problems within the year.
I will be closely monitoring the new drive, but henceforth will be considering other alternatives before choosing Samsung for my next purchase.
