Anecdote. I swore off spinning disks for my PC years ago, but I've been a bit cheap and recently got fed up with my 500GB "storage" drive always being near full and my work VM as well :/ So I finally went onto Google to look into storage and was absolutely, postively, shocked that I somehow missed the whole m.2 nvme surge. So much so that I got a 1TB 970 EVO for just $170. Nearly 500k random IOPS with qd32, and 3.5GB…

Does NVMe make a difference over SATA2? Isn't the latter plenty fast anyway? I've been holding off on upgrading because it doesn't seem like I'd see a benefit.

We are already past the SATA II bottleneck, so yes.

Setting aside the issue of counterfeits on Amazon, this is really nice. Clear, simple, functional and allows you to explore the space not just comparison shop for a specific item. I've long thought Amazon has terrible search and sort options for things like computer parts. Trying to buy e.g. RAM is a nightmare.

yea and totally broken UI on mobile. not their fault though. is it time for browsers to adopt a sensible default CSS for mobile?

Yes, NVMe is on a 4x pcie pipeline right to the CPU, where SATA runs through another chip.

SATA2 is really old. The SATA revisions are:

SATA1 - 1.5Gb/s SATA2 - 3.0Gb/s SATA3 - 6.0Gb/s

SATA3 is often referred to as SATA6G although because of 8b/10b encoding overhead you a SATA6G link maxes out at 4.8Gb/s

There are many NVMe SSDs that use 4 lanes of PCI-E Gen 3 which is just under 32Gb/s

If you read this review you can see read speeds of 3500MB/s which is 28Gb/s or just under the 32Gb/s limit.

I am using lowercase "b" for bit and capital "B" for byte

Hmm, maybe my disk is using SATA3 then, I have an Evo and a not-ancient motherboard. However, I'm wondering whether I'll see a practical difference in my day to day workloads, which is mostly web development and no gaming.

Also because I was curious -- looks like LTO-8 is about $12.75 on newegg. Which is still keeping below disk - but only just (and ignores the cost of drives)

It's a pain to format LTO-7 for higher capacity in LTO-8 drives, but once you do it's only $5-$5.50 a TB

Your comment inspired me to do some math:

I have an old 24 tape robot I haven't used in a while. Priced out a used LTO8 drive and 24 LTO7 tapes, and assuming that they're formatted M8 to 9TB, it still costs out to $0.02/GB-- so only just breaking even with the 12TB USB3 external drives.

You need a lot of tapes before LTO starts comparing favorably to current drive prices even using LTO7 tapes. :( like 1PB before it's really attractive.

Plus, there are already PCIe 4 NVMe SSDs.

On windows, Windows Storage Space sucks. The RAID 5-like write performance is unusable. And Microsoft disabled the old mirroring alternative on most windows SKUs.

Storage spaces are not a RAID though, their purpose is to allow you to have a pool and manage it easier, the same thing in linux is LVM. Storage spaces do offer redundancy but how it works is a mystery I never had the courage to trust production server to it.

My understanding is that it is an implementation of software RAID that enables pools of drives of multiple sizes, plus some tiering for caching. Which is why they disabled the traditional windows software RAID.
