I see many posts asking about replacing the HDD in PS3s, but nothing about SSDs.

Given that the original PS3's 2006 release date was years before SSDs started to become mainstream, I could imagine issues with my console after installing one (lack of complete support in the OS, perhaps?).

Are SSDs fully compatible with PS3s? Has anyone tested this before?

  • Also, in Arqade there's a hard drive tag, but no solid state drive tag. Can anyone suggest it a new tag?

    I think hard drive tag would probably cover ssd's. possibly make hard drive and solid state synonyms of "storage" or something. maybe make a meta post

Yes, the PS3 is fully compatible with SSDs, though not necessarily optimized for it. There are many benchmarks that compare the difference in performance of a PS3 using an HDD or an SSD. Also keep in mind that people have been running Windows XP (released in 2001) on SSDs without much problems either.

Most of an SSDs internal workings aren't handled by drivers in the first place, and instead are the responsibility of controller chips built directly into the SSD. Those chips not only handle file seeking, reading, and writing (and deleting), but also wear-levelling — a feature which does not exist for HDDs, as it would be useless there.

Windows 7 was the first Windows OS to feature optimizations for SSDs. These optimizations were mostly deactivating HDD optimizations that made no sense for SSDs, such as defragmentation. It also introduced TRIM support, which helped with file deletion — yet another feature that made no sense on HDDs.

If anything, it is possible that the PS3 would suffer from performance issues when deleting or writing after deletion of large files, which is what TRIM support is meant to suppress.
