Toshiba presenta su SSD de 256 GB y 3 mm de grosorpor : Javier Pastor: 26 Set 2008, 13:08Este fabricante está dando muy buenas sorpresas en el mercado de las unidades SSD, y lo demuestra el último anuncio de esta firma, que acaba de lanzar un modelo con 256 Gbytes de capacidad y un formato de 2,5 pulgadas que, atención, tan sólo tiene 3 milímetros de grosor. Además de eso la unidad alcanza tasas de lectura de 120 Mbytes por segundo, y tasas de escritura de 80 Mbytes por segundo, unas cifras muy decentes que eso sí, no son las más rápidas que hemos visto. El mercado de las unidades SSD está avanzando y mucho
Oracle Tries to Step Up on High-End Databases.
PC World.com 20081007
Since 2005, Oracle Corp. has spent at least $32 billion on acquisitions -- turning itself into the vendor of a top-to-bottom enterprise software stack that is arguably broader in scope than any rival suite. In doing so, Oracle hasnt diluted its database focus. Sales of databases and middleware still account for more than half of its revenue. And according to consulting firm Gartner Inc. , Oracle controlled 49% of the global database market last year, with more revenue than the next four vendors -- IBM, Microsoft, Teradata and Sybase -- combined. But Oracle has shown some signs of vulnerability at the high end of the database market. For instance, many Web 2. 0 companies are eschewing its databases and instead running open-source technologies such as MySQL on grids of PC servers. And corporate users with data warehouses sized in the hundreds of terabytes, or even in the petabyte range, are finding column-oriented databases and specially tuned data warehousing appliances to be more scalable than Oracle databases are. So Oracles annual OpenWorld conference in San Francisco two weeks ago was heavy on database news, as the company tried to show that it is agile enough -- and its software is robust enough -- to respond to the new challengers. At the top of the list was Oracles announcement of a pair of hardware products -- its first ever -- aimed at users looking to get ultrafast performance out of their ultralarge databases. For the past six months, Oracle CEO Larry Ellison had teased users and analysts with hints that the vendor would introduce a database accelerator at OpenWorld. That turned out to be the Exadata Storage Server, which combines Oracles parallel query software with ProLiant servers from development partner Hewlett-Packard Co. What makes the Exadata system different from a typical storage server, according to Oracle, is the database intelligence built into the device. Ellison claimed that Exadata can speed up large queries by performing lower-level calculations on the information it stores and then sending the results to the main database, instead of flooding it with raw data.

Hard Disk Drives of Different Types: Hitachi 7K200 vs. Everyone Else.
Xbit Laboratories.com 20081006
2. 5-inch hard disk drives used to be considered an attribute of notebooks while their low storage capacity was put up with as an annoying, yet inevitable, drawback. This attitude seems to call for a revision now thanks to the rapid growth of recording density. The capacity of 200-250 gigabytes (and even 320GB in newer models) is quite enough not only for an office/workstation PC but also for a home multimedia/gaming system. What is good about 2. 5 HDDs, they feature low power consumption and, accordingly, low heat dissipation. They are also small and produce little noise. No wonder then that we now often hear about non-mobile applications of such HDDs. They are installed into compact computers such as the Mac Mini or AOpen miniPC. People who build silent PCs install such HDDs into full-size system cases instead of noisy 3. 5 models. And if you are planning to assemble a compact Network Attached Storage or even an inexpensive 1U server with a good disk subsystem, you may want to consider using 2. 5 HDDs as well. What about performance? How do 2. 5 drives compare with their larger counterparts in terms of sheer speed? This question has become even more interesting after 2. 5 HDDs with a spindle rotation speed of 7200rpm were introduced. Its the same speed as 3. 5 drives have. In this review, we will try to compare 2. 5 HDDs not only with each other but also with two 3.
