As a part of its “Quicksilver” project, IBM presents a new solid-storage device, sized at 4TB, the TechRadar website reports. The Project Quicksilver SSD hopes to replace spinning disks with faster and more powerful SSD’s. The mighty 4.1TB SSD is 250 times faster than the world’s fastest disk solution (so far, Mtron Storage Technology’s 128GB SSD was a revolutionary invention due to be produced beginning this year). The industry has already “crossed the 1TB threshold” since Seagate began to sell 1.5TB drives, however there are no harddrives with comparable capabilities. Performance improvements of this sort mean a lot for business, since two to three times as much work can be done in a given time frame. Besides the obvious speed and size advantages, the Quicksilver also is a power-saving device, since it uses about 50% of a standard set-up’s power and cooling, and its size is considerably smaller than its predecessors.

As arstechnica.com reports, the Intel corporation has officially launched the new X18-M and X25-M solid-storage devices that are customized for portable computers and desktops. Intel’s SSD is uses NAND flash memory built on MLC technology instead of a single level cell (SLC) design. At the moment, X18-M (1.8 inches) and X25-M (2.5 inches) have 80 Gb capacity. The reading speed of the device is 250 Mb/sec; recording speed is 70 Mb/sec. The device is connectible to a computer via a Serial ATA interface. These new Intel’s SSDs demonstrate very high level of operating speed results. In addition, these SSDs substantially decrease power consumption and are more reliable than machines which contain moveable parts. By the end of the year, Intel plans to introduce 160 Gb SSDs. Furthermore, in the near future the X25-E Extreme model for high-end servers will be released. This SSD will be built on single level cell technology, with reading speed 250 Mb/sec and 170 Mb/sec.

Samsung introduces a new 256GB solid-state drive. Simply called the 256GB FlashSSD, the Serial ATA drive reads in-order data at 200MB per second, or double the rate of Samsung’s past 128GB drive. It also boosts write speeds, often a bottleneck on solid-state drives, from 70MB per second to 160MB. The real advancement, Samsung says, is in the manufacturing process. Past drives, including the 128GB model, have depended on flash memory using a single-level cell storage technique. The 256GB drive is a switch to multi-level cell storage that apparently solves the problems of the format. The new drive controller not only gives it the same speed as single-level storage but also adorns it with longevity (about a million hours worth). As it’s more efficient in storing data, the multi-level cell technology is also “considerably” less expensive to produce, though Samsung has stopped short of revealing the exact difference. Samsung plans a 1.8-inch version of the 256GB drive that will ship before the end of the year, and has been Apple’s sole choice for the MacBook Air’s solid-state drive to date: a 64GB drive is used inside Air models configured with the SSD storage option.

Probably one of the main features of MacBook Air is the usage of a solid state drive. It’s expensive, but it’s faster and more reliable than a hard drive mechanism. SSDs use high density Flash RAM chips to store data in place of a conventional HDD’s magnetically read platters. SSD includes both Flash RAM chips and an ATA interface, so the computer treats the device just like a hard drive. Upgrading from the Air’s standard 80GB HDD to a 64GB SSD costs a steep $999. The biggest downside after cost is the drop in capacity. Formatted, the 64GB SSD has a capacity of 55.6GB. In disk reading and particularly random access reads, the SSD was dramatically faster: as much as 18 times faster. That means faster booting, faster application launching, and faster open file operations. SSD read speeds won’t make the overall system dramatically faster all the time, but they are noticeable any time a lot of data is being read.
