Fujitsu looks to flash for 1.8" storage needs

The market is definitely looking brighter for solid-state discs (SSDs). More and more manufacturers are beginning to embrace flash as a suitable alternative to traditional hard disc drives (HDDs) and device manufacturers are increasingly putting them in their mobile products.

NAND flash, which was once relegated to memory cards used in digital cameras and portable media players like the iPod, is now finding its way in larger capacities and faster operating speeds in UMPCs and notebook computers.

SanDisk recently announced a new 2.5" 32GB SSD destined for notebooks and Samsung countered with 1.8" 64GB SSD of its own offering read/write speeds of 65MB/sec and 45MB/sec respectively.

The lower weight, higher transfer speeds, lower power requirements and silent operation coupled with dropping flash prices has enticed Fujitsu to halt development of its 1.8" HDDs. The company reports that more portable device manufacturers are asking for solid-state storage instead.

Falling prices for 2.5" HDDs have hurt Fujitsu's profit margins, so it's no surprise that it is looking to NAND flash to increase its bottom line. "We want to see if the market tips toward flash, or if it stays with hard drives," said Masao Sakamoto, a Fujitsu spokesman.

Flash drives not as sturdy

You went on a rant about nothing.

The HDD manufacturers know all about wear-leveling flash, just like the regular flash mem makers.

NTFS can write to the same damn block a million times and it won't matter. Yes, literally.

It's handled in hardware, and has been for ages now.

Every reputable flash card/drive company has wear leveling build in. So if you write to one sector 5000 times, they will be written to different physical location in a circular fashion.

Yet another reason not to buy a cheap no-name brand of flash card/drive.

It seems to me that most companies are simply slapping on NAND flash with a IDE/SATA interface, with no regard for wear-leveling or garbage collection.


All flash IDE devices will have hardware wear leveling.

IDE interfaces have been on flash since the beginning. Non-IDE interfaces like SD or MCC are actually fairly new. Look up what compact flash was doing in the early 90s.

You don't actually know what garbage collection is, so don't use it.

Wear-leveling must be handled somehow: either in hardware (unlikely given the amount of space required for look-up tables), or by the filesystem. To date, I haven't read of any new filesystems for Windows which incorporate this feature.


Oh wow. You should quit while you're ahead.

My apologies for the ill-informed rant. Need to read up more on the issue....


Portable devices...

It's only a matter of time now (probably 2-3 years) before most portable devices that currently have hard drives will probably be switch to using SSD's instead. I imagine the smaller-storage size iPods and similar music devices will be some of the first to embrace SSD's.




Good news...

Quick adoption of SSDs will help lower the cost in a shorter time frame than originally anticipated. A win for the consumers...




Do they have to do something ?

They built their own hard drives, but for flash memory, I don't think they will build it, at least not now.

They will have to get flash memory and place it in a 1.8in cover. There is not so much research to do to build a SSD. The only research are in process for building flash memory at low price and at high speed.
