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.
Itâs the 6000M SSD thatâs the most interesting, though. It will use 15nm flash memory to offer 6TB of storage while retaining the 2.5-inch drive footprint. Read speeds are expected to be 540MB/s and write speeds of 520MB/s, which is typical of any high-end 6Gbps SATA SSD today.Pricing has only been announced for the 1TB drive, which is set at $820. We can expect a large premium on the 3TB model, and an even larger premium on the 6TB drive.heyâll also cost significantly less than even a 1TB SSD. However, that doesnât mean we arenât getting larger SSDs, and the worldâs first 6TB SSD is set to launch in July. Japanese manufacturer Fixstars is planning 3 new 2.5-inch SSDs carrying the names 1000M, 3000M, and 6000M.
