As part of the 2013 Samsung SSD Global Summit here in Korea, Samsung announced that latest member to their SSD lineup – the Samsung SSD 840 EVO, under the banner ‘SSDs For Everyone’.  This new drive will be available in 120 GB/250 GB/500 GB/750 GB/1 TB capacities, using 19nm Toggle 2.0 TLC, compared to the Samsung SSD 840 which uses 21nm Toggle 2.0 TLC and the 840 Pro which uses 21nm Toggle MLC. We also upgrade to the Samsung MEX Controller onboard, one up from the MDX.

The big thing Samsung want to push with the EVO is the increased write speed for the low capacity models. Using a new feature called 'TurboWrite' (more info on this as we get it), compared to the previous 840, whereby the 120 GB model was rated at 130 MB/s and 86K/32K 4K random IOPS, the new 120 GB model is hitting a rated 410 MB/s write speeds.  The peak 1 TB model is rated for 540/520 MB/s sequential read and write, with 98K/90K IOPS respectively.  The 1 TB models will also feature 1 GB of LPDDR2 DRAM Cache.

Enterprise storage is also the focus of the SSD Summit, with Samsung unveiling the XS1715, an ultra-fast NVMe (Non-Volitile Memory Express) SSD with up to 1.6 TB of storage.  The XS1715 is the first 2.5” SFF-8639 SSD using PCIe 3.0 to provide a maximum sequential speed of 3 GB/s, along with 740k IOPS.  The XS1715 will be available in 400GB, 800GB and 1.6 TB versions, with plans to develop the line of NVMe devices.

More information from the Summit as it occurs throughout today and tomorrow!

UPDATE: Pricing is as follows:

Thus for the 1TB model, $650 makes the drive $0.65/GB.  At the 250GB price point, the basic Evo package is $190, compared to the current 840 standard price of $175 at Newegg.

    Well, it's meant for mainstream consumers, hence the "SSDs for Everyone" slogan. Enthusiasts will still want the 840 Pro for the longer warranty and much higher write IOPS. Reply

    Adding to what Duraz0rz said...
    The 840 Evo is an upgrade to the regular 840, not the 840 Pro. The 840 Pro remains the more expensive, higher performing option.

    I'm confused, why would you think the TLC using Evo was replacing the MLC using Pro? Reply

    Thanks for posting this news!

    Nice to see those higher speeds on the 120GB consumer model.

    Also, will be interested to see how the enterprise line stacks up to Intel et. al

    What I'm really interested in is native PCIe SSDs for consumer desktops as SATA 6Gbps is the main bottleneck now. Sammy are already doing it for laptops as the 2013 MBA has one, but for desktops there's no option other than to stump up a lot of money for an enterprise-grade drive that's overkill even for enthusiasts.

    Uh-oh... another TLC.
    Well, it's nice for people doing almost nothing on their computers (with the advantage of less noise due to SSD versus HDD), but for power-users TLC is a no go!
    I have a tiny 60GB Intel 335 SSD and it has gathered over 15 TB of writes in half an year ! That's an average of 83 GB /day. How ? I'm actually USING the computer... to do work, etc.
    These TLC drives would die on me rather quickly....

    If you're writing 83 GB/day you're not a normal user and thus you would be using the wrong drive with a TLC SSD. Nevertheless, assuming a rather high write amplification factor of 3x, if you were to choose a 500 GB model, you would still have a 5.5 years endurance minimum. Reply

    HardOCP projected failure for the 128 GB drive with a light usage pattern in just a few years. Reply
  • Solid State Brain - Thursday, July 18, 2013 - link

    How many years? What write amplification value they used? Reply
