16 TB SSD : Awesome & Priced Accordingly
Samsung produces some of the best SSD's 
For $10,000 you can get one that holds 15.36 TB 

SSD's are way faster than HDD's, they allow computers to boot up from cold off faster, apps launch faster, and in many common workflows they transfer files faster with better read and write speeds than traditional spinning metal magnetic platter drives that have been the dominate norm in computer data storage for a long time, built on top of magnetic spin data storage technology that was iteratively developed and continues to be used with tape drives with remarkable data storage capacity but slow IO performance. 

The Machine referenced in the paragraph below :) 

I am rocking one of Samsung's older 840 series units of 256GB in the 08 MacBook that was used to publish this posting! One of the earlier SSD's aimed at consumers, it was ~$300 back then, the second SSD upgrade for this machine. The first was a 128GB Corsair Performance SSD. Both of these upgrades were radical performance increases vs the poky 128GB HDD that shipped with this base model Late 08 MacBook. The ram was upgraded to 8GB and the machine is on its second battery now! I can not upgrade the software to the newest macOS Sierra, stuck with OS X El Captain, but that is ok. I need to clean up the drive too, only ~57GB of remaining space left.

The 16TB SSD Tech  <- Link

Based on a SAS interface aimed at enterprise users, the 2.5in size means 2x more drives in a standard 2U rack! Utilizing next generation advanced 3D V-NAND technology with greater performance and efficiency. 

Each 256Gb die is stacked 16 layers deep to form a 512GB module, 32 used in the 15.36 TB drive. Each die is made of 48 layers connected with a PM1633a lineup that is faster and more reliable than the previous generation. A proprietary controller and firmware contributing to the performance increases.

Read at 200,000 IOPS, Write at 32,000 IOPS, sequential speeds of 1,200 MB/S, 2x faster than typical SATA SSD's. The controller has access to 16GB of DRAM. Reliability improved to 1 complete 15.36TB of data written per day, between 2x and 10x more writes than planar MLC and TLC flash tech. Metadata protection offers enterprise level security!
