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.
Jeff Atwood got a lot of attention for his blunt assertion in this May 2011 post that âSolid state hard drives fail. A lot.â And yet, he concludes, they're worth it: SSDs are so scorching hot that I'm willing to put up with their craziness. Consider that just in the last two years, their performance has doubled. Doubled! And the latest, fastest SSDs can even saturate existing SATA interfaces; they need brand new 6 Gbps interfaces to fully strut their stuff. No CPU or memory upgrade can come close to touching that kind of real world performance increase.
