Samsung solid-state NAND hard drives will be cheaper than reported, more versatile

Earlier today Samsung announced its 4GB solid-state NAND hard drives. The 1.8" and 2.5" devices will primarily be marketed for enthusiast and high-end desktops supporting Microsoft Windows Vista's ReadyBoost feature.

A DailyTech competitor claims "Samsung confirmed to TG Daily that the SSD is likely to be priced below $200," implying the price of the drive would be just under $200.  In fact, when DailyTech talked to Samsung the company confirmed that the device will cost significantly less than that, perhaps as much as $100 less. The company has not released pricing on the drive yet, but current prices on the NAND spot market quote 4GB of flash memory between $62 and $70.  Samsung Semiconductor's Director of Flash Marketing, Don Barnetson, was able to confirm that a slight premium on these prices was more in line with real pricing of the drives.

Samsung clarified during our conversation that the initial versions of the SSD will feature a Parallel ATA interface as opposed to the newer Serial ATA interface use in notebooks and PCs. Additionally, many of the chipsets Intel is releasing do not support the PATA interface so Samsung will definitely need to think about switching to SATA sooner than later. The SSD drives can be mounted in a PC using mechanical mounts or a 2.5-inch slot.

According to Samsung, the 4GB SSD should be ready to ship in time for the Vista launch, and features 57MBps read speeds and 31MBps write speeds and up to 5,000 operations per second.

That link is talking about Vista/Longhorn. Windows today is very brain-damaged and doesn't use RAM nearly as well as it could. I've got 2GB of RAM installed in my laptop, only about 200MB of it ever goes to the buffer cache, with typically 1.3GB unused. Even when I start a disk and memory intensive job (compiling code) it never caches as much as it should. (And yes, I've already done all the registry tweaks to enable the large cache, etc...)

The Windows cache manager acts like it's allergic to RAM, and tries to empty it as much as possible, dumping out pages even when there's no memory pressure whatsoever. Stupid.

You need to read more closely. From the article...

In today's versions of Windows, a technology called the Windows Prefetcher performs simple memory caching in a bid to improve overall system performance. The Prefetcher uses available system RAM to cache, or prefetch, memory pages that it believes the user will need in the future. The goal is to reduce unnecessary disk access because random disk I/O is one of the most obvious performance bottlenecks on a typical PC. "To get the disk out of the way," Aul told me, "the Prefetcher precaches the data it thinks you will need. That way, the disk read operation won't be necessary."

Windows XP's Prefetcher performs this service for a wide variety of file types, including Windows Explorer, the Windows boot files, and others. But Prefetcher has some limitations. If you run several memory-intensive tasks (e.g., games, graphics editing, video editing) all of those cached memory pages will be pushed out to the disk-based page file. So when you go back to a cached task, the system has to read them back from disk, thus obviating any performance benefit.

What does it matter? It's obviously broken.

I see the same thing happening as well. It normally uses about a few hundred megs of system cache, out of 1.5 free gigs.

He's right to say that this is retarded. Dram, unlike flash, do not have any real write limits.
