SSD brings new options to the table

While the cost off SSD storage is still high compared to HDD storage SSD brings in new abilities in how to utilize storage. I have seen a trend when large storage devices with 10s to 100s of SSD bays are combined with a smaller number of HDD bays to create a storage array that can be carved up to looking like anything you want. VMs typically required a fairly small amount of space for the OS installation but fragmentation in HDD dictates that you have a fair amount of extra space to ensure the perform levels of the volume does not start to tank.

With the virtual storage arrays you can allocate smaller partions because fragmentation is dealt with at higher levels than the allocated volume. Additionally you can allocate more space to the volume dynamically but with some of that space non-dedicated to the volumes. The speed of the SSD lets you manipulate how the storage is allocated without the penalty that using HHDs would incure. Yet if you need a large chunk of storage and performance is not a big issue you can take a chunk of HHD storage and meld it into the mix.

While HHDs these days are large and cheap in general, the higher performance drives typically 10K RPM drives are still pricey and in lower desinties so they are not as much of a bargain as the slower HHDs. HHDs are likely to continue getting bigger but not much faster, while SSD are getting bigger and faster. SSD are also smaller and even at this time you can get nearly as much SSD storage in the same space as HHDs. When you add the lower power consumption requires less cooling then the SSDs start paying back over time.

On the subject of hybrid drives, I though that could be a great solution in the consumer space but so far it seems to be DOA. I have only found 1 drive available at the places I shop and it did not impress me. Part of the problem is the cost of the SSD storage added to a HDD makes for a non-competitive price. But it would be great to have some decent storage in my laptop with enough SSD memory to make it perform better than I am used to a laptop performing.

I think part of the blame for the common consumer could be placed on Microsoft's doorstep in trying to push Windows 8.0 on consumers in an attempt to grab the android tablet look and feel market.( Note:I personally love my Win7 AMD-6core machine for real work.)

 

Usually a new OS goes with a shiney new computer, with included and scaled-up hardrive, for this type of user.

The pushback from the consumers has been to keep the older PC until the OS justifies a new machine.

The tablet and Table-like PCs almost exclusively use flash or SSD's.

I know Windows 8 can be setup an used as a capable Win7 upgrade, but most users don't realize that or have the savy to reconfigure the look and feel of Win8.

Yes, access time is key for many high performance users including gaming systems.  The hybrid drive has a solid state drive and a large hard drive built together to get a large capacity and the speed of SSD.  I think these will be more popular for performance needs with some trade off for cost and capacity.

Even a small amount of access time improvement can go a long way as far as newer technologies are concerned....access time is key.

They didn't mention hybrid drives.  I guess they are lumped in with the HDD.  No additional reliablity compared to HDD, I would guess.  Just some access time improvement.

Reminds me of the first mainframes that used tape for storage.  You would see them movies with the large tape drives spinning back and forth.  I'm sure the new ones would be a little smaller.

I thought so too, but he works on those big tape arrays and swears there is enough error correction and redundancy to make them safe, besides being more cost efficient than spinning disks of data no one is looking at.

tape is an interesting alternative, may be a bit of a risk though.

I've got a friend in the industry and he keeps telling tape is making a comeback as longterm replacement for spinning media.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
