DELL PERC H755 RAID controller PCI Express

Product Overview

AI-generated summary

The Dell PERC H755 is one of those “boring but important” upgrades: it tends to suit organisations that want reliable RAID management without getting fancy. The big question isn’t whether it works—it almost certainly does in the right Dell platforms—but whether you’ll actually benefit from it versus simpler onboard options. At **~£1082 ex‑VAT**, you’re paying for controller class consistency, better manageability, and usually a smoother experience with Dell’s ecosystem.

Who should buy: if you’re running a Dell server that supports this controller cleanly, have multiple drives where RAID level flexibility and dependable rebuild behaviour matter, and you want firmware-level stability with good monitoring. Who shouldn’t: if you’re building a small, low-risk NAS or you only need basic redundancy, the cost-to-benefit can feel steep—especially if your server already covers you with onboard RAID. Also be cautious if your environment is mixed-brand or you’re not sure about compatibility/firmware support; chasing the “right” backplane/cabling/controllers can quickly erase the savings on paper. If you can confirm it’s the correct fit for your exact server model, it’s a solid buy; if not, I’d pause and verify first.
