Used NVMe All-Flash Storage Buying Guide: Pure FlashArray, NetApp AFF, HPE Nimble

This guide is for: A mid-market IT manager needing 5PB of storage who’s debating whether to buy a used all-flash array or sign up for cloud storage. You want real numbers, not vendor hype.

I sold a Pure Storage FlashArray //X 200 to a startup for $25,000 in 2022. Six months later, they called because the array’s drive wear metrics had hit 60%—a red flag. I told them to pull the drives and check the SMART data myself. Turns out the previous owner had run that array at 80% utilization for three years. They ended up paying $15,000 for premature drive replacements. You lose $50,000 if you skip due diligence on used storage arrays. Period.

Should You Pay $3,000–$5,000 for a Support Transfer?

Let’s talk Pure Storage first. A used FlashArray //C 100 will cost you $18,000–$22,000 if the warranty is expired. But if you can transfer the original support contract, add $3,500 for a three-year extension. I’ve seen buyers skip this and get hit with $12,000 emergency call-out fees when a controller fails. NetApp AFF A800s are similar: used models with active support drop $20k in value versus those without. Check the expiration date before closing.

NetApp AFF A-Series: Is 40% Drive Wear a Death Sentence?

NetApp’s All Flash FAS (AFF) A700s are popular in the used market. You’ll pay $28,000–$32,000 for a 12-drive model with 2.4TB NVMe drives. But here’s the catch: use the ONTAP System Manager to check the “Drive Health” tab. If the wear percentage is over 40%, walk. Drives in these arrays rarely last past 60% wear without rebuild hell. I’ve seen A800s with 35% wear last five more years clean as a whistle. At 50%? You’re looking at $8,000–$10,000 in drive replacements every 18 months.

HPE Nimble AF vs. Alletra: Which Used Model Is a Landmine?

HPE Nimble AF 1520s are gold if you can find one with HP’s “Predictive Analytics” license still active. Used prices range from $15,000–$18,000 for 48TB raw. But the Alletra 6000 series? Avoid unless you’re getting it under $10k. Those arrays are Nimble rebrands with marketing rebranding—same hardware, higher sticker price. Also, Nimble AF arrays need annual firmware updates. If the seller hasn’t applied the latest patches, you’ll spend $4,000–$6,000 on compliance fixes.

Used vs. Cloud: Do the Math on 10PB Workloads

Say you need 10PB of active storage. AWS S3-IA would cost you $200,000/year in recurring fees. A used Pure FlashArray //X 600 (60-drive config) can do that workload for $50,000 upfront, plus $8,000/year for power and cooling. But here’s the rub: if your data growth exceeds 20% annually, you’ll be buying another array in 14 months. Cloud scales; used hardware doesn’t. Use used arrays for static workloads. Let the cloud eat your variable ones.

When to Walk Away from a “Great” Used Deal

I see it all the time: someone offers a “steal” on a 4-year-old HPE Nimble AF 3020 for $9,000. It’s got 12 x 3.8TB NVMe drives, but the array’s support expired 18 months ago. Transferring support would cost $4,500. That’s 50% of the original price. You’re better off buying a 3-year-old NetApp AFF A400 for $14,000 with active support. The math isn’t just about the array—it’s about the total risk you’re shouldering.

What to Do Next

1. Insist on a remote login to check drive wear metrics (Pure: array health; NetApp: sysconfig -a; HPE: InfoSight dashboard).
2. Verify the remaining support contract in writing before paying a dime.
3. Compare the cost of 3-year cloud storage vs. a used array + support transfer. Use a spreadsheet—don’t trust your gut.

[How to check drive wear on a Pure Storage FlashArray //X]
Log into Pure1, go to the array’s “Health” tab, and look for “Drive Wear %.” Anything over 35% is a red flag.

[What is the price range for a used NetApp AFF A800?]
$28,000–$32,000 for a 12-drive model with 2.4TB NVMe, depending on support status.

[How much does support transfer cost for a used HPE Nimble AF array?]
$3,000–$5,000 for 1–3 years, depending on model and vendor.

[Is it worth buying a used Pure Storage FlashArray //C?]
Yes, if you can get it under $20k with 2+ years of support left. Otherwise, save for new.

[How to compare used NVMe array costs vs. cloud storage]
Calculate 3-year TCO: array + support + power vs. cloud’s recurring fees. Use 10% annual power inflation for arrays.
