Due to what Samsung is citing as a surge in demand for larger capacity SSDs, they have now launched two new models offering up to two terabytes of storage each. In order to drive the extra capacity, they have also launched a new SSD controller in the MHX controller. Our resident SSD expert Kristian expects the MHX to be similar in design to the MEX controller, but with additional DRAM to track the extra blocks.

The 2TB 850 EVO leverages the same 32-layer 128 Gbit TLC V-NAND that we have already seen in the smaller capacity 850 EVO products, but the 850 PRO will use a new 128 Gbit 2-bit MLC die, but still at 32-layers. It should be a nice addition to the 850 PRO series, especially with the rise of 4K video and the extra storage it requires.

Samsung 2TB SSD Specifications
Model 850 PRO 850 EVO
Controller Samsung MHX
NAND Samsung 128Gbit 40nm MLC V-NAND 32-layers Samsung 128Gbit 40nm TLC V-NAND 32-layers
Sequential Read 550MB/s 540MB/s
Sequential Write 520MB/s 520MB/s
4KB Random Read 100K IOPS 98K IOPS
4KB Random Write 90K IOPS 90K IOPS
Power 5mW (DevSLP) / 3.3W (read) / 3.4W (write) 5mW (DevSLP) / 3.7W (read) / 4.7W (write)
Encryption AES-256, TCG Opal 2.0 & IEEE-1667 (eDrive supported)
Endurance 300TB 150TB
Warranty 10 years 5 years
Price $1000 $800

Samsung will still package these drives in the same 7mm 2.5” SSD enclosure which means they will be SATA based for now, but Samsung has said they will be moving their 3D NAND to mSATA and M.2 form factors as well. Endurance ratings for the drives are 10 years or 300 TBW (Terabytes Written) for the PRO, and 5 years or 150 TBW for the EVO model.

The 850 Pro retails for $1000, and the 850 EVO retails for $800. Although not inexpensive by any means, and still much more than the $75 of a spinning disk, the prices are right around double the 1TB models in the lineup so there is not any extra premium to get the larger models at this time.

Kristian should have a full review of the new models soon.

    Uh no, they work with massive data sets and 3D images/videos from MRI, CTs, X-Rays. So yeah, pr0n I guess if you like looking at sick people's bones and guts. :)

    if they are working on big data sets quite often you be better of a business dive that is meant for mass Writes or you could ignore the 300TB warranty bit and just use them until they die, which would be over 2PB-8PB written data (better off with Pro version as they are quite solid to the point they silently Die as the pro uses MLC not TLC) i would use HDD sentinel and basically keep an eye on uncorrectable errors

    VMs can benefit significantly from SSDs, and typically consume a lot of space. I'd gladly take 2 for our compile farm at work.

    At my last job, we purchased a dell server with SSDs off ebay. It was a godsend for virtualization. Nothing can slow that machine down.

    Today, there was a review in Tom's IT PRO for the Seagate Enterprise Performance 10K v8 1.8TB. It is a hybrid drive with $850 pricing. I wonder where is the value in that compared to these two Samsung drives.

    Wow, 2TB in a2.5" package?
    I guess we'll never see 2.5" samsung M9T spinpoints beyond 2TB then.

    What about the second part of the Broadwell review?
    Could you tell us things about the Compute capabilities of the GT3e?

    Thank You.

    please forgive this. It is about ffffing time . I am so on this I have been looking for one for more then a year.

    Back in March I wrote Samsung asking specifically for a 2TB 850 Pro and also M.2 form factors in the 850 Pro series. I'm sure they already had something in the works, but this announcement makes me feel like I actually accomplished something with that effort.

    Will it come with working TRIM that doesn't corrupt data?
