Case Study: Lakeland Health achieves dramatic EHR performance gains with Pure Storage

Lakeland Health Prescribes Pure Storage to Solve Lagging Storage Performance

Lakeland Health, a Michigan-based healthcare system running the Epic EHR across hospitals, clinics and 5,000 users, faced persistent storage performance problems: its legacy spinning‑disk array repeatedly failed Epic certification, produced high latencies that delayed clinicians’ access to critical patient data, and demanded significant management and upgrade costs just as it neared Epic’s Good Maintenance deadline.

After a risk‑free Pure Storage proof‑of‑concept, a FlashArray passed Epic tests on the first try and Lakeland deployed three all‑flash arrays across production and DR. Read latencies fell from ~14 ms to under 2 ms, nightly reports dropped from 8–10 hours to 15 minutes, write times improved sixfold, exception rates fell ~35% and clinicians save over 350 hours/year; IT now spends far less time on storage, enjoys a smaller footprint and benefits from non‑disruptive Evergreen upgrades.
