Urgent help installing Sandisk Ultra Plus SSD

[boncoe]

Well, the fact is that I am installing Windows 7 Pro from scratch, I only have my SSD connected to avoid confusion and it turns out that instead of marking me 128 GB of capacity that the disk has, it only marks 120. Is this normal? Does the same thing happen with mechanical disks that mark less capacity than the one we buy?

well if I have a crucial of 64 Gb and I only have 59.5 GB available

Well… 1 GB is exactly 1024 mb.

1 Byte = 8 Bits
1 Kilobyte = 1024 Bytes
1 MegaByte = 1024 kilobytes
1 Gigabyte = 1024 MegaBytes
1 TeraByte = 1024 GibaBytes.

If we think about it, a GibaByte should be 1000 MB... and a MB should be 1000 KB... and above all, a KB should be equivalent to 1000 Bytes

For this, a new measure was created, the Gigibyte (Giga Binary Byte - GiB)
which is what the manufacturers of storage units use

Gigabyte - Wikipedia, the free encyclopedia

Well, what a hassle, 8Gb lost all over the face. On SSDs it's not the same as on mechanical ones where the number of gigabytes is cheap, here it's the opposite.
In summary, I put the AHCI mode in the bios, I update the firmware of the SSD, and as for Trim and cache memory, do I have to do something else? I have Windows 7 installed

This is normal in almost all disk drives. They all come with between 5 and 10% less than the total capacity (manufacturers report this in the "spec sheet")
We all feel a little pain about this, but there is nothing we can do but endure it… To make you feel that your problem is smaller, I will tell you that when you buy a 1.5Tb drive and discover that it comes with 1.36Tb, then you really feel angry for losing nothing more or less than 140Gb…

I don't know, as has already been said it's normal that you buy a disk of 128,000,000,000 Bytes which are 128GB = 119.20 GiB (which comes from dividing by 1024). It's not that you lose absolutely nothing, it's just that for years the capacities on hard drives have been given in GB (decimal system) and when on a computer you see its capacity in GiB (base 2, binary system) it turns out that logically it is a lower capacity because GB and GiB are not the same. On computers measurements are given in KiB by tradition when working in binary, but really when you buy a disk and they tell you it's 128GB they are not lying in the least since it is the correct nomenclature; in addition in many they indicate 1º that the measure is decimal and 2º that the useful size of the disk may be somewhat inferior:

We all feel a little pain about this, but there's nothing we can do but suck it up... To make you feel that your pain is less, I'll tell you that when you buy a 1.5Tb drive and discover that it comes with 1.36Tb, then you really feel angry for losing no more no less than 140Gb...

Well you're right, the bigger the capacity, the deeper the sting.

This is especially bleeding in SSDs due to over-provisioning.

But to minimize this is over-provisioning and so on (Write amplification - Wikipedia, the free encyclopedia), I have not noticed it at least. I suppose it will be noticed having many small files, databases, data center, etc. but in a normal OS it does not seem to be a problem. PD. And there are disks that already come with a size reserved for these purposes, in the 840pro in addition to the 256GB it has 7% reserved by the controller, so you do not need to lose or intentionally leave free space for the OP if you do not want to.
