Samsung was strangely absent from FMS this year, but they had us out to NYC yesterday for a briefing we've been waiting a looong time for:

Above is a spec layout for Data Center SSDs that are to be in the retail channel, meaning they will be available for purchase on the open market, not locked behind exclusivity contracts with a select few corporations, as was the case previously. Here's the abbreviated rundown:

  • 860 DCT
    • SATA
    • Low write workloads
    • 960GB, 2TB, 4TB
    • Low cost (~0.25/GB)
  • 883 DCT
    • SATA
    • Mixed workloads
    • Power Loss Protection
    • 240/480/960GB, 2TB, 4TB
    • $0.30/GB
  • 983 DCT
    • NVMe (M.2 / U.2)
    • Mixed workloads / higher performance
    • Power Loss Protection
    • 960GB, 2TB
    • $0.34/GB

The prices above are MAP (Minimum Advertised Price) as MSRP doesn't carry over to enterprise products quite the same. Performance details are above and below in the full press release, but the gist of them is that they are comparable to current Samsung SATA and NVMe products with the exception of random writes being rated at steady state sustained values (client SSDs are typically rated for reduced span random writes of shorter durations).

There was another thing to check out as well:

That's Samsung's elusive Z-SSD, now with the model name 983 ZET. It contains slightly modified V-NAND operating in straight SLC mode and with some additional tweaks to help reduce latencies - referred to by Samsung as Z-NAND. Here are the specs:

We did note that some of what drives those super-fast latencies is the use of a DRAM cache. We won't know how this impacts larger span random performance until we can test this product first-hand. Samsung also showed where they expect these new products to fall relative to other competing offerings:

I'm thrilled to see Samsung finally opening up their Data Center parts to the rest of the masses. We'll be testing and reviewing these as samples arrive. I personally can't wait, because Samsung's data center parts are known for having amazing QoS performance, and I can't wait to throw our enterprise test suite at them!

Read on for Samsung's full press release, with specs!
