Verbatim has the LTH technology developed to produce cost-effective blanks, namely using DVD technology. This is first of all laudable. However, this technology has a serious problem for the customer: it creates BluRay blanks whose data security is worse by a mile than the conventional BluRay blanks! This means that the blank, although less expensive to manufacture is (what is probably teiweise passed to the client), but also considerably worse. These are not mere assertions. I'm using a Pioneer BDR-208DBK drive for burning. This drive is very tolerant of problematic blanks. A focal demolition I have not had it. It also burns these blanks and they are also readable and playable on various Leselaufwerken.ABER: it is striking that when verifying / reading a relatively low speed is reached, which is well below that of, for example, BD-RE media. And after I've burned the media then examined with Opti Drive Control (analysis of the error number / frequency) I also knew why this is so: They are all critical error rates recognizable. No outliers - no, Mitter values! That may also explain why so many read drive comes in distress. Quite different "normal" BluRay blanks without LTH technology: fantastically low error rates, high reading speed. A study has found that it significantly to poor looks at the data stability of LTH media than with "normal" BD-Rs. No longer wonder and means to me: Stay away from this consumer-lie! Steel beam made of plastic are also intended cheaper than real! Verbatim, so it does not go! LTH = data loss. I fear, after one or two years it could have happened to the data and I'll write off the 25 disks as dues and rewrite the data on "normal" media. Verbatim also has this (DataLife). I can only advise everyone to take a very critical supposedly customer-friendly cost optimization over. LTH or writing quality - both simultaneously closes out apparently.
