Why are there so many different types of storages? Is there like a totem pole of what’s best? I know the new intel Optane ssd just came out(not sure if that’s worth buying btw???) but anyways what’s the difference between nvme, m.2, u.2, PCIe express... maybe there’s more too?

Ok first off you pretty much have two types of Protocols. SATA and NVMe. SATA is anything that is connected via a SATA Cable or is wired for SATA (M.2 has SATA wiring in the same socket). NVMe though requires PCIe Express lanes. Now any SSD that runs on PCIe Lanes is a NVME. So whether it is plugged directly into a PCIe Slot, a M.2 Slot or a U.2 slot (Same as a M.2 for the most part but is used to connect a cable to a 2.5/3.5 inch PCIe SSD vs a stick like SSD that you screw in)

Optane is just a new type of SSD but still require PCIe lanes.

Now will you see any real world difference between a SSD, NVMe, and Optane? No. Honestly for day to day stuff you could plug a SSD into a 1.5Gbps SATA Gen 1 slot and STILL not see a difference with...

No. Honestly for day to day stuff you could plug a SSD into a 1.5Gbps SATA Gen 1 slot and STILL not see a difference with everyday things as it maxes out at 150MBps and most regular hard drives run 80-130MBps. Only if you were coping big files, working with RAW files, a SQL Database that maybe has thousands of people on it, etc would you see a difference.

The difference Optane brings to the table is that it could be used as RAM and you can have instant on and off as when the power gets turned off the RAM doesn't lose all its memory but it still isn't as far as normal RAM though. The RAM version i think is still in development.

But yea honestly for everyday use just stick with the cheaper SATA SSD. To use NVMe SSD's you really want to use windows 10 and install from scratch (Otherwords no cloning from you current SATA SSD to NVMe SSD)

it comes down to cost and speed. a standard ssd on a standard mb maxes out at 600 bytes/bits. on read/write from most vendor spec. the 2.5 inch format is the cheapest form of ssd good for entry level builders.
the m2 slot came out next. give pc builder or home builder to add a ssd that small footprint on the mb. the down size of m2 is heat. if there not cooled they can slow down when taxed. the m2 not bad for entry level gamers for cost and that want keep wires down in a build.

nve are the new replacment for the 2.5 inch ssd. there dropping in price to replace the older 2.5 inch drives. as there real new there have been issue with mb bios and posting/installing windows. some time using a nve you have to do more steps now to install windows 10 then using an m2 or stock ssd.
what you want look now is cost/speed. if two ssd from samsung are withing a few bucks. (m2 vs nve.) go with the faster nve. the faster you can move data from point a to point b. the quicker the os feels. my dad pc that newr cpu and ssd then mine is faster on boot and feels smother running web stuff. it the same when your used to fast downloads then end up at friend who has dsl...your download is crawling and you want hurt you friend for being cheap.
