64GB flashdrive as Hard Drive?

post #1 of 20
Thread Starter 
Hi,

I was wondering if there would really be huge benefits to using a flash drive as a hard drive, that is installing an OS and games on it and booting from it.

Considering the transfer rates and speed are better than even the fastest 15k SCSI drives (I think) that would seem to be a better solution than even raptor's in raid0, and it's perfectly quiet too.

Am I missing something? (maybe despite the extremely high cost involved)

You're not missing anything at all. SSDs (solid state disks) are where the market is moving. You can already find smaller models in laptops due to their decreased battery usage and silent operation. It'd be a very high-performance option for a desktop, especially in RAID.

Nope, transfer rates are still only like 20-60MB/s last I checked. Highend hard drives are usually 85-130MB/s. Magnetic win in sequential I/O. However, flash win in random access.

The trend will be hybrid drives first (normal hard drive with a chunk of flash) since flash GB/$ prices still aren't even close to magnetic hard drive prices. A 64GB flash drive is currently around $500. A 64GB HD is like $30?

Yes, price is a problem at these larer quantities, but speed? I am not sure where you are getting your information... solid state is faster.

The SSD reads 300 percent faster (53MB/s) and writes 150 percent quicker (28MB/s) than normal hard drives.

I want to see where you have drives that have 85-130 mb/s average read speed.

This is not to mention durability and power conservation of SSM. Solid state memory will be the future, its just a matter of time.

The fastest reading I got with a regular sata 3.0 250gb hitachi was 50, Raptor was 55-60

only problem other than price i can see is temps. id imagine the temps will be somewhat higher than regular drives

Flash drives have limited read/write cycles. You'd kill a flash drive in less than a day if used as an OS/game "HDD."

They've got to compare 97 harddrives... my RAID (2 harddrives) does about 110 mb/s, and 56 mb/s when they're solo.

*EDIT*

Pook, not if we're talking about the SSD, they're much more durable. Besides, it wouldn't be 1 day for the standard SIMD(isn't that's what it's called?), but more like a week or few.

Not according to Samsung:
Quote:
Samsung says their solid state drive will use 95% less power than regular laptop drives, not to mention that they'll also be quieter, weigh half as much, and emit considerably less heat.
