It is often seen in the plates/electrodes of car batteries, as it is formed when the battery is discharged (when the battery is recharged, then the lead sulfate is transformed back to metallic lead and sulfuric acid on the negative terminal or lead dioxide and sulfuric acid on the positive terminal).ead(II) sulfate can be dissolved in concentrated HNO 3, HCl, H 2 SO 4 producing acidic salts or complex compounds, and in concentrated alkali giving soluble hexahydroxidoplumbate(II) [Pb(OH) 6 ] 2â complexes.
IHS is projecting SSDs with average capacity of 190GB to be priced at $110 by the end of this year, dropping to $104 for a 243GB drive by the end of next year. SSD prices will be $89 for 275GB by 2016, $73 for 310GB in 2017 and $60 for 345GB in 2018. The laptop SSD price drop will come as more people move from hard drives to SSDs, which are faster and draw less power, Zhang said.
The best SSD. 1  Hits 500 MB/s read speeds. 2  Outperforms more expensive SSDs. 3  Great price per gigabyte.  Speed can drop under heavy prolonged write 1  loads. Lower capacity models are slower.  Slower than M.2 / U.2.
