OCZ’s new Z-drive

Dubbed the Z-Drive R2, the solid state drive (SSD) boasts improved performance with a twist. The twist is “optimized” NAND modules that are interchangeable. That makes swapping out bad parts (not that you will ever have to, right?) a snap if needed. Or even upgrading to larger storage capabilities if you should need more room. Did I mention that you can boot from it too?

“Speeds can hit up to 1.4GB/s, and capacities will be available from 256GB to 2TB” (link)

Price is Right

Get ready for a price adjustment. Affordable SSD’s will soon be on the way. JMicron’s new NAND flash controller could cut prices of solid state drives in half. The JMF612 chip design suits the current generation of flash chips utilizing smaller process geometries. The new chips are smaller, faster, and most importantly cheaper to manufacture. Intel and Micron are working on building 34nm NAND flash chips while Samsung and Toshiba are following closely behind. The cheap controller board combined with newer higher density flash memory add up to a widely affordable storage unit by late Fall. Look for many data centers to convert to solid state technology later this year. (link)

MLC NAND technology to put SSDs in every household

MLC (multiple level cell) NAND technology allows for higher density of data storage capacity. This could greatly lower costs for data centers by up to 4 times. There are still some performance, reliability, and endurance issues to work out but the technology looks to make solid state drives a household product.

SLC (single level cell) NAND memory can store 1 bit per cell. This allows for higher read/write speeds and up to 100,000 write cycles. MLC NAND memory is capable of 2,000 to 10,000 write cycles but can store multiple bits per cell meaning more storage capacity. As well in order for MLC to function properly complicated firmware is required to handle data allocation and organization. (link)

The main problem with SSDs has been write performance. The fixed block sizes forces inefficient handling of data storage. Data is spread out evenly across the flash memory but slows access time and increases wear and tear. Adding RAM buffers can speed up read/write times.

Gadget: Toshiba 512GB SSD

I’m sure the engineers at Toshiba are yelling ‘ FIRST!’ To be showcased at the 2009 CES in Nevada next year Toshiba’s 512GB SSD is sure to make a splash. Seated within a 2.5″ case and utilizing 43 nanometer NAND technology to ensure speed, performance, and efficiency. No price has been announced but expect it be expensive. Are these drives the best idea during these trying economic times? Someone must be buying them if SSD development is still going full throttle. Smaller drives, larger capacities and demand are driving research into SSD technology. However still strangely silent have been Seagate and Western Digital. Still no drives expected from them. Perhaps SSD is just a fad? We’ll just have to see who’s lining up to buy these drives when the are mass produced next year.

Toshiba comes out with 32GB flash memory chips

Toshiba tonight upgraded its onboard flash memory with a new, 32GB module destined for smaller portable devices. The storage combines eight 4GB NAND flash chips built using a smaller 43 nanometer manufacturing process and makes a single package, fitting twice as much capacity into a similar space as before. The design also builds in its own controller to manage its data traffic and would let device makers drop the new package in without reengineering their hardware.

The combined storage is explicitly intended for cellphones, portable media players, video cameras, and other devices where a large amount of storage is necessary in one package. Toshiba doesn’t name individual customers, but is a key supplier of Apple and through the design would enable a 32GB iPhone as well as a 64GB iPod touch. Toshiba also produces its own electronics, including Gigabeat media players, and frequently sells its memory for competitors and manufacturers of MMC and SD cards. (link)
