If you are buying 400-AEXX in bulk, verify the exact spec your chassis and RAID controller require before you place the order. As hinted, these parts are often end-of-life and priced accordingly, so small mismatches (caddy type, sector size, firmware) can turn into returns and delays.

Practical checks to send your vendor:

  • Confirm drive form factor and carrier: 2.5 in SFF vs 2.5 in drive in a 3.5 in hybrid carrier. Make sure the caddies match your backplane.
  • SAS link speed: 6 Gb/s vs 12 Gb/s. 12G SAS will down-negotiate to 6G, but do not assume the reverse.
  • Sector size: 512n/512e vs 4Kn. Older PERCs (e.g., H700/H710) do not support 4Kn; stick to 512-based drives on those.
  • Encryption: SED/FIPS vs non-SED. Mixing SED and non-SED can disable features or complicate arrays.
  • Dell firmware and LED support: ask for Dell-labeled drives with Dell firmware; verify the DP/N on the label and that the Locate/Blink LEDs work in your chassis.
  • Health data for used/refurb: request SMART/drive log screenshots (power-on hours, reallocated/pending sectors, error counts).

On receipt, burn-in spares before adding to production arrays. For PERC/MegaRAID on Linux, you can read SMART through the controller and run a write-verify on a non-production disk:

# Example: check physical drives behind a PERC (adjust N)
smartctl -a -d megaraid,0 /dev/sda
smartctl -a -d megaraid,1 /dev/sda

# Destructive test on a spare drive (double-check device!)
badblocks -wsv /dev/sdX

If total cost of ownership matters more than exact part matching, ’s point stands: consider moving to newer-generation 12G SAS 10K drives or SSDs (supported by your PERC/backplane) and migrate arrays, rather than chasing legacy stock.

Google that number and see what's out there. This looks like your 311185-001 request and for hardware that beyond its service life. These also look expensive due to the simple reason only those that need them, need them. Why not replace these with something made today?

It's a big world, here in the US there appears to be some at the shops I see with a google.

PS. https://www.newegg.com/dell-401-aasm-1-2tb/p/1Z4-000J-00J86?Item=9SIAAEE7U02864 seems to be a good price. How many there? Ask them.
