Tom's Hardware recently had the chance to interview Steve Pereira, vice president of Hitachi Global Storage Technologies in the EMEA region, who talked about SSDs and the future of the hard drive in 2010 and beyond.
When will we see 4TB drives? I am desperate for cheaper prices for high capacity drives (1.5TB-2TB)! I am hoping that the arrival of 4TB will drive the drop in price that I need before I can afford to upgrade my 750GB ones...
How about more reliable storage solutions? I've been experiencing three failng hard drives within a short period of time. So now I have bought a bunch of hard drives to be used in a cheap software based RAID6 cluster (ZFS using raidz2).
I must say that I'm quite tired of all those WD MyBooks. There are a lots of cables when you get to have a few of them, they all fail eventually, and their powersaving "feature" is annoying. So I think external enclosures that doesn't have all those bells and whistles (that are useless but costs alot) but can fit several hard drives (preferrably using hot swap bays) and don't require 10 separate E-SATA cables to connect to the computer could be a nice thing. It is possible with the SAS interface to fit several hard drives into one SAS cable which you cannot with SATA/ESATA. One SAS-Cable (e.g. SFF-8087/8088) is intrinsically designed for four (there are 4 hardware lanes in it) hard drives but by using SAS expanders (which usually are integrated in the external enclosures) you can connect a lot more SAS and SATA hard drives to it. SAS (at least without RAID, which you don't need anyway when using raidz and ZFS) is not so expensive and multibay enclosures with SAS Expanders don't have to cost that much.
There are alot more Solid State storage technologies out there than the flash and I think it would be reasonable to believe that we will see storage devices based on those in the future, especially those that are not prone to degradation from write cycles.
The price of storage has been dropping pretty rapidly in the last year... In 6 months the price of a 500GB 3.5" drive has dropped by about %30. The larger capacity drives are like anything new - the price will be high to begin with and then it will drop when the next best thing comes along...eventually the price will return to a high point when the product is past its useby date (DDR, DDR2, and DDR3 standards are probably the best examples of this)
