Samsung Ships Hybrid Hard Drives 118
writertype writes "ExtremeTech reports that Samsung has become the first company to begin shipping hybrid hard drives as discussed last fall on Slashdot. (Some photos here.) Unfortunately, there's no word yet (beyond 'soon') on when retail shipments will begin, or when (or if) 3.5-inch models will be available. Note that these hybrid drives are different than the ReadyBoost USB flash drives optimized for Vista; hybrid drives contain a smaller amount of flash, and work as a write cache for your notebook drive, extending battery life."

Reasons?
1. Hard Drive reliability - See the security now podcast or read google's paper about hard drive reliability. The manufacturers are lying BIG time about how bad it's gotten. And SMART is a steaming pile of nothingness that can and is wildly inaccurate.
2. Latency (not speed) is so much better than hard drives.
3. Power and heat - Flash memory does not generate near as much heat or draw as much power. Plus we can expect densities to get higher so the footprint probably will be smaller than hard drives
We've already seen it in handhelds. It's moving to laptops (Toshiba and Fujitsu already are selling laptops)
If it has a mechanical action to it, it can fail horribly.
just my 2 cents.

The average human is good for 10,000 to 1,000,000 hours.
10,000 hours = Roughly 1 year, 50 days
1,000,000 hours = Roughly 114 years
Most people do die in that timespan, even if it is a little broad.
Anyway, back to flash: Those numbers aren't from the same variety of flash, they might be using one that averages say 800,000 erase/write cycles, with 99.999% of devices being within 50,000 of the average. I certainly wouldn't mind knowing how long I was going to live that precisely, and I definitely wouldn't mind living 800,000 hours (I'd be 91!).

In a couple of Gig you can easily store an operating system, many applications and many documents. For company PC's it would make sense to just load the OS and applications from flash and store the documents on the network. Really big files -media files- may still be stored on a (external) disk, that spins up when needed.
Currently I am trying to create a (headless) server that just runs from flash, without any mechanical parts whatsoever (using a VIA EPIA mainboard, I don't need CPU cycles or high redundancy). With flash it will be silent, will use almost no power and quick to boot. Maybe I'll even try to use RAID-5 on a couple of flash drives, why not? RAID is rather fast when latency is low, so it should be possible to get rather high speeds even with flash ( 3 * 15 MB/s is still 45 MB/s - less than 60 MB/s for a hard drive, but close enough).
