QNAP is ignoring UNIX KISS and load heaps and heaps of programs pre-installed, pre-activated on their QNAP NAS which not only slows down the NAS, it is also a privacy (thumbnails that NEVER get deleted) and security problem.

Year 2000 has passed, no flying cars yet but at least more faster (SSD and NVMe) disk space 😀 All sorts of resources also digital resources and bandwidth, RAM and DiskSpace space are STILL precious and should be treated as […]

UNTESTED! 😀 these drives are called: “U.2 PCIe NVMe” no kidding, search for em on ebay. “Micron has been developing some of the world’s most advanced memory technologies for more than 40 years, including DRAM (Dynamic Random Access Memory) and […]

currently testing the AMD workstation with the KINGSTON SKC3000D2048G NVMe, directly attached to one of the 2x NVMe slots (no RAID), as this NVMe drive seems to offer excellent price-to-disk-size-and-performance-value, if it is a kingston-quality drive, then there should be […]

what to expect? (click here for two html embedded test video files, if the user’s browser can playback 264x and 265x) while x264 and x265 are surely great codecs, the re-encoding of x264 to x265 is very CPU and thus […]
