i needed to upgrade my working station for trading and developing new trading indicator and EA, so i decided to buy 3rd nvme disk
Once i saw that prices, it blow my mind
Samsung NVME 4TB 9100PRo for allmost 1 350$
and
Samsung NVME 4TB 990PRo for allmost 990$
But i had to buy one so i bought, but seems to me no so cheap like it was.
What are your experiences?
Preserve your own money. Scale with the market's money. Exponential growth is the ultimate key.

Storage pricing has been rude lately — especially the big NVMe sticks when you’re buying “I need it this week.”
For a trading + EA/dev workstation I care about boring reliability more than peak Gen5 brochure speeds. Charting, tick archives, and symbol history are mostly sequential/mixed workloads; a well-cooled 990-class drive is usually plenty. The 9100 Pro numbers look lovely in a bench screenshot and matter less once Windows Search and Chrome have joined the session.
Practical split that worked for me:
OS + platforms on one NVMe
Historical data / VMs / builds on a second
Keep a third slot or SATA SSD for cold archives so the trading disk stays lean
£/$ shock aside: confirm cooling and DRAM/cache behaviour under sustained write (tick dumps). Thermal throttle mid-backtest is a real annoyance. Did you go 9100 or 990 in the end, and are you running it as the OS disk or a data volume?
