Faster than SSDs: That’s what DDRAMDisk memory promises, which uses RAM chips via NVMe.

You didn’t understand anything from the capo of the article, we’ll translate it for you: SSDs are fast, but not fast enough for certain applications. The built-in flash memory reaches its limits, especially with random access. This is the premise of DDRAMDisk. The name is barbaric, but very explicit: it’s about using RAM memory as storage.
Record read and write speeds
It works: In this configuration, the performance is simply impressive. When reading and writing sequentially in Crystalmark, the DDR4-based configuration reaches 15 and 14.7 Gb/s, and with random access (RND4K Q32T16) the speeds remain very high: 3.4 and 3.77 Gb/s.
Performance could be even better, but the limit is at the connectivity layer: the eight PCIe Gen 4 lanes. However, compared to flash memory, RAM memory has one major disadvantage: without power, data is lost. To correct this, they use a battery cell built into the module.
Integration is difficult…
In addition, there is another problem. You need a huge box (with 18 memory modules) that is well ventilated (because it produces a lot of heat). We’ll let you judge the photo below and imagine yourself on your PC. In short, not in everyone’s hands.

When and at what price the third version of the DDRAMDisk will be available is not known. As a reminder, the first version was sold at 256GB for $320. In addition, the semiconductor crisis continues to cause setbacks in the entire hardware industry.
