Do SSD need cache?

Yes, most SSD’s have a cache in volatile memory like SRAM or SDRAM, but it is not necessarily required for high performance. Certainly the size of the cache is less of an indicator of performance with SSDs than it is with hard drives.

Should I disable write caching on SSD?

Yes, it is safe — but it will slow your drive writes. It is almost always best to enable write caching on SSDs for consumer use as it allows data to be initially stored in DRAM or SLC NAND and then written to the drive NAND, which accelerates writes.

Should you enable write caching?

To answer the question, although write caching does improve performance, its benefit should be carefully balanced against the cost of possible data loss or corruption, and a UPS should always be present if write caching is enabled.
