So I'm trying to create a parity drive using storage spaces on my computer. Which from what I understand is supposed to be basically like RAID 5? With RAID 5 however I always thought that you basically had storage space equal to your number of drives minus 1, to allow for parity so if one drive died you could replace it. So that's what I expected to get when trying to set up this drive on storage spaces as well, but now I'm having some confusion.
If you look at the picture, it shows that my total capacity in the pool is 5.45TB which makes sense (~.9TB per drive x 6), but then when I go to set the size of my new drive, I write in 4.5TB (so allowing ~1TB for parity), and underneath that it says "including resiliency: 6.74TB". Which I don't understand, is that saying that parity will take up an addition 2.24TB? That's way more than it should be right? Or am I misunderstanding this? It will let me make it either way, but it says something like "A storage space can be larger than the amount of available capacity in the storage pool. When you run low on capacity in the pool, you can add more drives", so does that mean its going to ask me for more drives when I should still have another 1.24TB left to go?
I've tried googling all over the place and can't find a good answer on this for some reason, so I'd really appreciate if someone could shed some light on the situation.
Thanks!

You create a new storage pool for the following disks on your Windows 10 computer:
• Serial ATA (SATA): 1 TB
• Serial Attached SCSI (SAS): 1 TB
SATA and SAS are two different types of drives with different connectors/interfaces.
What is the maximum size you can allocate for your new
storage space?
Unlimited. By using thin provisioning, you can create a storage space that is larger than the available capacity of the storage pool. For example, you can set it to 4 TB; when the storage pool approaches capacity, you will receive a warning and you will need to add more disks to your pool.
You have a new desktop running Windows 10. However, you try to copy your file repository and find out that you do not have enough disk space. You have 400 GB of free disk space on your C drive and you have 3 smaller 500 GB drives. What can you do?
You can use the small drives and create a storage space and storage pool. Storage Spaces is a feature in Windows 10/Windows Server 2016 that allows you to combine multiple disks into a single logical volume that can be mirrored to protect against one or more drive failures. When the drives are combined, Windows places them into a storage pool. These storage pools can then be segmented into multiple storage spaces, which are then formatted with a file system and can be used just like any other regular disk on your computer.

computer science
The Hewlett-Packard 2114, 2115, and 2116 used a format with the left most 16 bits being the fraction stored in two’s complement format, followed by another 16-bit field which had the left most 8 bits as an extension of the fraction (making the fraction 24 bits long), and the rightmost 8 bits representing the exponent. However, in an interesting twist, the exponent was stored in sign-magnitude format with the sign bit on the far right! Write down the bit pattern to represent $$ - 1.5625 \times 10 ^ { - 1 } $$ assuming this format. No hidden 1 is used. Comment on how the range and accuracy of this 32-bit pattern compares to the single precision IEEE 754 standard.
