Yesterday, Samsung, one of the pioneers of the SSD, announced that mass production of several new models in 1.8" and 2" ½ format with a capacity of 128 GB and based on MLC chips has just begun. Others limited to 64 GB should also be mass produced starting this month. All use the SATA-II interface.
 In terms of performances, there will be reading/writing speeds of 70 MB/s and 90 MB/s which will enable them to rival certain SSDs equipped with more expensive SLC memory. Some rather good news is that power consumption was announced at 0.5W in use and 0.2W in standby. Otherwise, the Korean manufacturer took advantage of the occasion to reaffirm that a 256 GB model would enter into production at the end of the year. |

 Three months ago we mentioned the possibility of 55nm die shrinks for the G94 and G96 similar to what was done with the G92b that equips the GeForce 9800 GTX+. When everything goes well, there can be a double or even triple advantage because it can enable lowering production costs, increasing frequencies and/or lowering power consumption.
According to the Chinese newspaper Commercial Times, the G94b, G96b and G98b should arrive this year though not until September. Production will be entrusted to TSMC or UMC with costs that will be on average 20% lower. On the desktop, certain GeForce 9600s (G94), 9500s (G96, whose launch is planned late this month in 65nm), and 9300s (G98) could therefore have a smaller G9xb like some GeForce 9xx0 Ms expected out in the next few months.
Finally, despite delays at TSMC on the 40nm process, Nvidia and ATI still hope to have the first functional samples of GPUs with this engraving width before the end of the year. We’ll just have to wait & see... |

 Hitachi, which was up until now behind the competition in terms of density, has announced a new Deskstar generation, the 7K1000.B, that will enable it to surpass Samsung, Seagate and Western with a density as high as 375 GB per platter! Offered with capacities of 160, 250 (8 MB of cache), 320, 500, 640, 750 GB and 1 TB (16 MB of cache), the 7K1000.B, however, are not entirely equal regarding this new capability.
While the manufacturer does not give official details on the number of platters for each drive, they are divided into three groups for sound and voltage data: 160/250/320 GB (3.6w and 25 dBA at rest), 500/640/750 GB (4.4w and 24 dBA at rest) and 1 TB (5.2w and 27 dBA at rest). We can therefore conclude that they have a respective 1, 2 and 3 platters. The fact that the rotation sound level of the mono is higher than the dual platter can be explained by a simplified casing.
Thus, only the 750 GB drive has two 375 GB platters. And the others? Given the capacities we could think that surface densities are mixed, unless, for example, certain models only partially use their platters. Therefore, is the 1 TB composed of three fully used 333 GB platters or will there be three 375 GB of which only 89% is used? This is something we have seen in the past from Hitachi and only tests will tell.
Hitachi announces that the 7K1000.B as well as the professional version, the E7K1000 (differs by 32 MB of cache, a 5 year warranty and MTB announced at 1,200,000 hours) will be delivered this month to its clients. |
