AnandTech Storage Bench - The Destroyer

Our AnandTech Storage Bench tests are traces (recordings) of real-world IO patterns that are replayed onto the drives under test. The Destroyer is the longest and most difficult phase of our consumer SSD test suite. For more details, please see the overview of our 2021 Consumer SSD Benchmark Suite.

Energy Usage

On The Destroyer, ADATA's S50 Lite offers similar overall performance to good PCIe Gen3 drives and the early Gen4 drives based on the Phison E16 controller. The power consumption is also similar to the Phison E16 drives, which is a bit disappointing since the S50 Lite's SM2267 controller is just a four-channel design, which should save a bit of power.

AnandTech Storage Bench - Heavy

The ATSB Heavy test is much shorter overall than The Destroyer, but is still fairly write-intensive. We run this test twice: first on a mostly-empty drive, and again on a completely full drive to show the worst-case performance.

Average Data Rate
Average Latency Average Read Latency Average Write Latency
99th Percentile Latency 99th Percentile Read Latency 99th Percentile Write Latency
Energy Usage

As with The Destroyer, we see the S50 Lite's performance on the Heavy test falling in the same general range as the top PCIe Gen3 drives, and it is clearly slower than top of the line Gen4 drives. The S50 Lite also has somewhat disappointing performance on the full-drive test runs, with higher write latencies than we'd like to see from a TLC drive. Power efficiency continues to be poor, though it is within the normal range for high-performance drives.

AnandTech Storage Bench - Light

The ATSB Light test represents ordinary everyday usage that doesn't put much strain on a SSD. Low queue depths, short bursts of IO and a short overall test duration mean this should be easy for any SSD. But running it a second time on a full drive shows how even storage-light workloads can be affected by SSD performance degradation.

Energy Usage

On the Light test, the S50 Lite appropriately does well, with slightly better overall performance than any of the PCIe Gen3 drives, and decent full-drive performance with no concerning latency scores.

PCMark 10 Storage Benchmarks

The PCMark 10 Storage benchmarks are IO trace based tests similar to our own ATSB tests. For more details, please see the overview of our 2021 Consumer SSD Benchmark Suite.

PCMark 10 Storage Traces
Full System Drive Overall Score Average Bandwidth Average Latency
Quick System Drive Overall Score Average Bandwidth Average Latency
Data Drive Overall Score Average Bandwidth Average Latency

The ADATA S50 Lite underperforms on all three of the PCMark 10 Storage tests. The most important comparison here is probably the Intel 670p, which uses basically the same controller and theoretically inferior QLC NAND. But the 670p's firmware is tuned so that it gets the most benefit out of its SLC cache on all three of these tests, which clearly isn't happening for the S50 Lite.

    "All speech is subjected to censorship, including by the mind of the person producing it"

    Agreed; and that's a good point. But you know what I mean. The ability for someone to say or print something and not be persecuted or thrown into jail next morning. In the end it's all about finding truth. Opinion is usually worthless, but not tolerating it or dissent can lead to truth being swept under the carpet.

    Define 'nonsense' and provide examples from my posts, if you're going to try to act like unelected/non-credentialed forum police. 'I'm kinda with' is the sort of language choice that certainly instills the highest confidence and respect. Reply

    But we dont HAVE 10TB QLC drives. We have 1/2TB QLC drives, which have significantly less endurance.

    "go the fricka way" until you can come up with a better argument. So long as QLC is selling for TLC capacity and TLC price it is a worthless anti consumer tech.

    Hopefully these manufacturers will be getting back lots of dead drives if Chia proof of stake crypto-mining takes off. That will teach them to promote inferior technology! Reply

    They are cheaper, but only if you buy a SSD drive that doesn't use Gen4 Reply

    Looking at their recent history of sneakily replacing components on their SX 8200 Pro, I won't bother nor will I recommend others to use this brand. Reply

    I agree 100%. Reply

    Kingston pulled a similar trick with their V300 series of SSDs back in 2014, albeit "only" with slower NAND - I hear ADATA switched to slower NAND as well as a slower controller. Reply

    Kingston started the A400 with Phison S10 and TLC-NAND. Now, at least the 1,92TB use QLC and SM2259XT. Reply
