The SN580 also has SLC cache, although Western Digital does not mention the amount. The lifespan is up to 900 written terabytes for the 2TB variant.

The WD Blue SN580 will be available immediately in variants of 250GB, 500GB, 1TB and 2TB. The recommended retail prices are 58, 77, 110 and 219 euros respectively. In practice, the sales prices of WD SSDs are usually lower.
