I think I solved a major problem in the NAS industry

Date: September 10th, 2025 12:13 AM Author: https://imgur.com/a/o2g8xYK The problem is "write amplification" in NAS systems that were designed to run entirely on hard drives. When running Docker they write tiny amounts of data to the SSD every 5-10 seconds. Normally these would go to hard drives that are always spinning, but over time these writes can add up and shorten the lifespan of a SSD.
My previous approach was to put shitty old SSDs in the cache pools so that I wouldn't care if they died, but then I realized a bunch of these are the old school ones that have a DRAM cache. The DRAM cache shouldn't write to the drive until it's full, and the smallest drive gives you 64mb. The chances of it ever filling up 64mb with these tiny writes is slim, because whatever the OS writes every 5 seconds probably overwrites whatever it wrote 5 seconds earlier.
And now I have proof:

Two shitty old drives with DRAM caches report a 1:10 ratio of writes to reads. Previously it was 1:3-ish. The cache is usually a ratio of drive capacity, so a 512gb SSD has 128mb of cache, and it's hardly EVER touching that now. |

Also, this is only a problem in RAID arrays, and it's bigger problem in ZFS pools that BTRFS. It doesn't happen at all if you store the Docker image in XFS, but you can't have a proper RAID array with XFS. |

Unless your entire home is kitted out with 10Gbe (you would know if you spent the money on this), you'll never see anything faster than hard drive speeds across your network, if that. Go ahead and use the shittiest, slowest, oldest, shittiest and slowest SSDs for this application. Holy shit if you paid money for pcie 4.0 anything. Go ahead and use the slowest RAM you got too. Don't enable XMP (http://www.autoadmit.com/thread.php?thread_id=5771553&forum_id=2:#49249477) |
