Samsung SM863 & PM863 SSD Review (960GB)

SERVER PROFILES CONTINUED

Our last set of profiles include File Server and Web Server workloads. As mentioned before the last hour of preconditioning, the average IOPS, and average latency for each QD is graphed below.

The File Server profile is based on an 80% read/20% write mix. It’s made up of block sizes from 512 to 64K, each making up a different percentage of the access pattern. The pattern is: 512 bytes=10%, 1k=5%, 2k=5%, 4k=60%, 8k=2%, 16k=4%, 32k=4%, 64k=10%.

During the file server benchmark the SM863 is still on top maxing out at 29K IOPS and latency just over 1ms at QD32. The SM863 does well reaching 22K IOPS and latency under 1.5ms.

The Web Server profile is similar to the File Server profile, but has some additional 128K and 512K accesses thrown in for good measure. Additionally, the profile is 100% reads.

Now, this benchmark is where we should see very similar performance between the two drives as it is all reads. The SM863 still shows a slight lead over the PM863 with TLC V-NAND. Both are also significantly better performers than the M510DC.

It’s amazing that last year a slower 4TB drive went for $4,000, now for $2,200 you can do better.
Nice thorough review btw.

Does the SM863 (all capacities) support opal 2.0 out of the box?
