Samsung 860DCT SSD Review Discussion

Recommended Posts

The Samsung 860DCT is the company’s new data center SATA SSD. The 860DCT is a 2.5” form factor SSD with capacities as high as 3.84TB. The drive is built off of Samsung’s proven 3D V-NAND technology and is built for some serious endurance, 1,396 total TB written on the 3.84TB model. Samsung quotes sequential speeds up to 550MB/s read and up to 520MB/s write with random speeds of 98K IOPS read and 19K IOPS write. The drive is all about read-intensive and data-streaming data centers.

The fishhook is the point in over-saturation where the drive decreases performance as latency increases.

I brought this up here a short time ago. SR needs to link these graphs to an explanation page, or people are going to keep asking.

They're testing loads at successive % of capacity (0% - 120%) for each drive on a third axis (not shown). Then measuring both X and Y values. At any given test point, there is only one measurement.

For each drive, the graph gets weird when they hit 100% of their capacity. Flatter, more-natural curves are typical of higher-performance drives.
