SanDisk joins the Flash SSD arena

DailyTech reported yesterday that Samsung developed a new 50 nanometer 16Gb NAND flash memory chips that provide 100% faster read speeds and 150% faster write speeds. The announcement sparked a lot of interest from consumers looking for larger and faster offerings than Samsung's current 32GB Flash SSD drive.

SanDisk today entered the SSD fray with a 32GB drive of its own. The 1.8" SanDisk SSD Ultra ATA 5000 drive uses patented TrueFFS flash management technology and has a 2 million hour MTBF. The drive has no moving parts, so it is completely silent and weighs less than traditional 1.8" mobile hard drives. The drive also consumes 0.4W of power when active, versus 1.0W for a traditional mobile hard drive.

When it comes to performance, the SanDisk SSD Ultra ATA 5000 offers sustained reads of 62MB/sec and can complete random reads at 7300 IOPS (512-byte file size). The drive can boot Windows Vista Enterprise on a notebook in 35 seconds and has an average access time of 0.12 ms.

“Once we begin shipping the 32GB SSD for notebook PCs, we expect to see its increasing adoption in the coming years as we continue to reduce the cost of flash memory.  When these SSD devices become more affordable, we expect that their superior features over rotating disk drives will create a new consumer category for our retail sales channels worldwide,” said SanDisk CEO Eli Harari.

SanDisk leveraged technology from its acquisition of M-Systems in developing its new SSD drive. SanDisk gained a wide portfolio of 1.8", 2.5" and 3.5" SSD drives when it acquired M-Systems.

SanDisk’s new SSD Ultra ATA 5000 drive is currently available to OEMs and is expected to add $600 to the price of a new notebook computer in the first half of 2007. That figure is expected to drop as the year progresses.

Hard drives will definitely be replaced, but still really large storage devices!? I mean, you can get about 500GB hard drives today, for 250$, that’s 2GB/$. You find me a NAND storage device that cost effective and I’ll buy them today.

On the bright side though, A SSD (Solid State Disk) as so much better performance that if you start to replace the main operating hard drive with SSD you will get a lot more out of your PC.

Is it too far off to suggest that SSD and system memory in the future be treated as one? Instead of addressing memory you simply address the entire hard drive…

Actually, performance on these is on par for read, worse for write, and much better on seek time. I wouldn't call them a big step forward in terms of performance at all, just a sidestep. As for combining system memory with a hard drive, system memory reads and writes at a minimum of 50x the speed of this drive. Slow down your RAM that much and you will simply castrate your system.

The diffrence is that much then...

Then it's a waiting game, let's se what happens. research and improvments are always comming...

Exactly, 35 seconds to boot windows is not overly impressive, my computer can do it in around 40 seconds, and I have 2gb ram and a 250GB sata3 hard drive. But I guess in the notebook realm performance is taken with a grain of salt. It is the lack of moving parts which reduces noise and energy use, which is what researchers were aiming for in the end. Personally I can stand waiting a few more seconds on my laptop if the battery life is better.

SATA...3??? And where did you get this hard drive?

I think what he meant was SATA 3.0Gb/sec or the newer SATA version, to differential it from the older SATA 150 (or 1.5Gb/sec). This is how the drive interface is listed at Newegg

Not according to this on Playfuls regarding this drive. I think performance issues are rapidly increasing as the size gets bigger, the die gets smaller, and the power requirements get smaller. These things are getting damn fast which is why the hybrid drives are manufactured by Samsung.

http://www.playfuls.com/news_05695_SanDisk_Unveils...

The SanDisk SSD announced today achieves a sustained read rate of 62 megabytes (MB) per second and a random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transferiii – more than 100 times faster than most hard disk drives. Taking advantage of this performance, a laptop PC equipped with SanDisk SSD can boot Microsoft Windows Vista Enterprise in as little as 35 seconds. It also can achieve an average file access rate of 0.12 milliseconds, compared with 55 seconds and 19 milliseconds, respectively, for a laptop PC with a hard disk drive.

I think you are referring to SSDs that use regular system ram. These do have fantastic performance, but need a constant power supply. The only consumer lever Dram SSD released was gigabyte's iRAM, and it never made the splash people thought it would. (having a price 3 times higher then they said didn't help)

Where you buying drives. You can get 500GB drives for $150.
