- SN8100 TOPS SSD based on flash with record speeds and large thermal -free thermal
- The Sandisk SN8100 offers superb PCIe Gen5 performance with almost 15 GB / s of reading speeds
- Optane P5800X, four years of Intel, always exceeds SN8100 in real world speed tests
The new SSD WD Black SN8100 PCIe Gen5 of Sandisk is fast, efficient and designed to meet the requests of players and power users.
The reader uses a PCIe Gen5 X4 interface and is available in capacity 1 TB, 2 TB and 4 TB. Built around the 8 -channel controller internally of SanDisk and the NAND TLC BICS 3D, it supports reading speeds up to 14.5 GB / S and writing speeds up to 12.7 GB / S, which placed it among the quickest Gen5 discs currently available.
However, despite the peak design of the SN8100 and the impressive references, the Optane P5800X, now disappeared from Intel, still holds the fastest SSD in real use.
The landmarks suggest advanced speeds – but not at all levels
In synthetic benchmarks like CrystalDiskmark and Ato, the SN8100 breaks laboratory recordings for sequential flow and random readings, reaching up to 2.3 million PIO.
According to Tweaktown, “this SSD is like no other; It is at least 20% more powerful than any SSD based on flash that we have never met. ”
It also demonstrates a significant efficiency, consuming only 7 watts under the load and requiring no active cooling, making it a serious competitor for the best SSD or the best portable SSD for fascinating constructions.
However, synthetic references do not always reflect the performance of the real world. In practical transfer tests, the SN8100 ranked ninth in the general classification, indicating that even if it is extremely fast, it is not without limits and does not dethrone the Intel P5800X optan.
Launched in 2021, the P5800X remains unequaled in the reactivity and latency of the real world. While its sequential reading speeds amounted to 7.2 GB / s – more slowly than the SN8100 – its random reading / writing IOPS exceed 4.5 million, and latency falls frequently below 10 microseconds. This is where it really shines.
SSDs based on flash like the SN8100 are always based on the collection of garbage and management at pages, leading to occasional latency peaks during small random workloads. On the other hand, the P5800X maintains coherent performance under a heavy load, without significant DIP, a key reason why it is always considered the fastest SSD ever made.
That said, the SN8100 is an impressive full -fledged journey. This is a personalized version of the SM2508 controller from Silicon Motion, improved with proprietary technologies like NCACH 4.0 and WD Black Gaming.
It is also integrated into the Sony PlayStation 5 extension slot, reaching 6,550 MB / s reading in this configuration, well above the minimum requirement of the console. However, with a price of $ 280 for model 2 TB, it clearly belongs to the premium level.
