Calculate more damage when buying storage devices

A decade ago, the 500 MB photo collection was considered a "wonder". Now, people can only be proud if their photo store is counted in gigabytes. But consumers' greed "has not stopped there.

Hitachi manufacturer has released a 1 terabyte (TB) hard drive. It looks like many other products but is equipped with orthogonal recording technology (PRM) to store information. Meanwhile, an organization about "hybrid" equipment is Hybrid Storage Alliance, which supports a flash-integrated laptop.

" Hybrid products will extend battery life. If you have to sit on an airplane for 2-3 hours and need to work to keep up with the project schedule, the battery life will be the problem you care about most then ", Joni Clark, Chairman of Hybrid Storage Alliance, said.

Some storage device companies, including SanDisk, are also beginning to consider flash solutions. The company claims the flash drive will be available this spring. Laptops using flash memory will boot quickly, reduce power consumption and are less likely to lose data in case of more computer crash.

However, the maximum storage capacity of flash drives is only 32 GB. " I will never pay attention to a child like that because they download movies every day, " said Amos Marom, SanDisk's computer solution manager. " And I'm like a warrior, when at the airport, while in the hotel room, back at the train station. I only need 20 GB and the battery is important ."

Another advantage is that the flash drive does not heat much, so the device is not as hot as a hard drive. SD flash memory card has also achieved great progress with 8 GB SDHC line.

In terms of durability and stability, optical drive will be the number one choice. Disks using holographic light can reach over 300 GB and store data on any location of the disc, not just on the surface.

However, even if you want to own holographic discs, users still can't find it in stores. " Products of this type are not on the market for high prices, " explains Elizabeth Murphy, holographic drive manufacturer InPhase. " Such a drive will be sold for about . $ 18,000 ".

The cheapest device is still the traditional hard drive, which has been improved with the new version - external Serial ATA drive. It is considered a big change because the USB connection was previously used only for keyboards and mice, and now supports storage devices. Furthermore, removable SATA drives also operate 6 times faster than integrated drives.
