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.

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.

    When will they be available for purchase. I just checked amazon and newegg, and they are not listed.

    A Finnish web store lists an estimated time of end of August for the EVO model. No time is listed for the PRO.
  • hulu - Tuesday, July 7, 2015 - link

    Actually, it literally says "latter half of August".

    wonder how many are whacking the reload button every time they look at the anandtech page in anticipation of the review

    I hope people are not rushing to store their 4k video collection on 1000$ SSDs..
    (editing is quite a different task, of course)

    Ups, I meant to cite the article here: "It should be a nice addition to the 850 PRO series, especially with the rise of 4K video and the extra storage it requires."

    If you're doing 4K editing, this could be really helpful.
  • Impulses - Tuesday, July 7, 2015 - link

    Even if you're not storing it, 1TB could get cramped depending on what other stuff you keep on the OS drive and how many 4K editing projects you have going on at the same time...

    It might make more sense to just get two 1TB drives in RAID tho, on a desktop at least, but I suppose 2TB drives open up the possibility of simple 4TB arrays which could probably satisfy most usage cases.

    My laptop has a single 2.5" bay and an mSATA slot. I currently have a 256GB mSATA boot drive and a 2TB Samsung HDD. I'd love to drop the HDD entirely and switch to an SSD but can't right now as I couldn't fit all my steam games on 1TB :D

    You could just use a 4 disk raid 0 array for editing since it is sequential and still pull 400 mbps.
