SSDs fail silently unlike HDDs, often entering a read-only safe mode that prevents booting. The takeaway is that a PC should be treated as a compute node, not a storage vault, and a NAS provides automated, redundant backups without relying on cloud subscriptions — removing human error from backup strategy entirely. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### why did my SSD suddenly stop being readable with no warning signs SSDs can fail silently because NAND flash memory does not degrade gradually with audible symptoms the way spinning hard drives do. When the controller detects uncorrectable flash translation-layer mapping errors or experiences a firmware panic, it can lock up entirely or enter a permanent read-only safe mode, which blocks the operating system from reading boot metadata and causes a total system failure. _Anyone rethinking backup strategy after a drive failure can browse related storage and NAS discussions on daily.dev._ ### should I store my important files on my PC's internal SSD or on a NAS Critical files are safer on a NAS than on a PC's internal SSD, since a PC should function as a compute node with its NVMe slots reserved for the operating system, active applications, and scratch files. A NAS centralizes storage with automated background integrity checks, instant snapshots, and offsite cloud syncing, removing human error from the backup process entirely. _daily.dev helps developers weighing local NAS setups against cloud storage compare real-world tradeoffs._ ## Similar posts on daily.dev - [A Dropbox user lost everything and proved why you need a NAS, not cloud storage](https://daily.dev/posts/a-dropbox-user-lost-everything-and-proved-why-you-need-a-nas-not-cloud-storage-xwd2s31gr) · XDA Developers · 0 upvotes · 0 comments - [Why I bought a 16TB HDD instead of an 8TB SSD](https://daily.dev/posts/why-i-bought-a-16tb-hdd-instead-of-an-8tb-ssd-ki5vmixwy) · XDA Developers · 0 upvotes · 1 comments - [My NAS corrupted years of files because I ignored three critical setup mistakes](https://daily.dev/posts/my-nas-corrupted-years-of-files-because-i-ignored-three-critical-setup-mistakes-yx7b75ced) · XDA Developers · 0 upvotes · 0 comments - [My NAS ran out of space, but the real problem wasn't the size of my drives](https://daily.dev/posts/my-nas-ran-out-of-space-but-the-real-problem-wasn-t-the-size-of-my-drives-3aa73xjgt) · XDA Developers · 0 upvotes · 0 comments - [I stopped adding containers to my NAS when I realized what actually belongs there](https://daily.dev/posts/i-stopped-adding-containers-to-my-nas-when-i-realized-what-actually-belongs-there-vyhhmucsi) · XDA Developers · 1 upvotes · 0 comments --- Tags: [#storage](https://daily.dev/tags/storage), [#homelab](https://daily.dev/tags/homelab) [View this post on daily.dev](https://daily.dev/posts/i-lost-4tb-of-files-in-a-single-ssd-failure-and-now-i-understand-why-a-nas-should-come-first-w8r4zqgy3) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I lost 4TB of files in a single SSD failure, and now I understand why a NAS should come first","url":"https://daily.dev/posts/i-lost-4tb-of-files-in-a-single-ssd-failure-and-now-i-understand-why-a-nas-should-come-first-w8r4zqgy3","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/i-lost-4tb-of-files-in-a-single-ssd-failure-and-now-i-understand-why-a-nas-should-come-first-w8r4zqgy3"},"datePublished":"2026-07-12T23:03:19.580Z","dateModified":"2026-09-14T08:01:55.098Z","description":"A personal account of losing 4TB of data after a primary SSD failed without warning.
