Solidigm SSD

The Solidigm D7-P5520 is an enterprise U.2 drive with absurd endurance, 7168 TBW, and solid sequential speeds. It's great for workstations but weak for gaming and useless for portables. Buy it only if you need the endurance and can handle the U.2 form factor.

Sequential reads hit 7100 MB/s and writes come in at 4200 MB/s. That read speed is genuinely strong, landing around the 76th percentile in our database. Writes are fine but nothing special for PCIe 4.0. The real story here is endurance. At 7168 TBW, this thing sits in the 97th percentile. You could write over 3.8TB to it every single day for five years and still be within warranty. Random performance is more middle of the pack at the 59th percentile, so don't expect it to crush consumer workloads that lean on small file operations.

Against consumer drives like the Samsung 990 PRO or WD Black SN850X, the D7-P5520 looks weird on paper. Those drives are faster in random workloads, cheaper per gigabyte, and actually fit in a normal M.2 slot. The Samsung and WD drives will run circles around this thing in gaming. But none of them come close on endurance. The Micron T710 and Seagate FireCuda 530R are closer in spirit, but they're still consumer drives with consumer TBW ratings. If you're comparing this to other enterprise U.2 options, the D7-P5520 holds its own. Against consumer NVMe drives, it's a different tool for a different job.

Pricing is all over the map. US listings range from $1,634 to $3,076, which is a $1,442 spread for the same drive. The lower end of that range is actually reasonable for 3.84TB of enterprise TLC with this endurance rating. The higher end is a hard pass. If you're shopping in the US, the cheaper listing is the only one worth considering. European pricing sits around €2,692 to €2,891, and UK buyers see £1,599. This is not a budget drive by any stretch, but for workstation users who need endurance, the entry-level US price is defensible.

The Solidigm D7-P5520 is an enterprise-grade U.2 drive that somehow ended up on a consumer retail shelf. It's built for data centers, with a 3.84TB capacity, PCIe 4.0 speeds, and endurance numbers that would make most consumer SSDs blush. But that U.2 form factor means it won't fit in your average gaming rig without an adapter and some patience.

Our scoring puts this drive at 78.2 overall, with workstation use being its clear sweet spot at 79.8. Gaming lands at a mediocre 51.8, and portable use is basically a joke at 19.6. This is a drive with a very specific audience, and it knows it.

Skip this if you're building a gaming PC, upgrading a laptop, or want something that just works out of the box. The U.2 form factor adds friction, the gaming performance is mediocre, and you'll pay a premium for endurance you'll never use. If you need a fast boot drive or game storage, grab a Samsung 990 PRO or WD Black SN850X instead. They're cheaper, faster in random workloads, and drop right into an M.2 slot.

This drive is for workstation users and homelab tinkerers who need serious write endurance and don't mind the U.2 form factor. If you're running a database, doing heavy video editing, or building a ZFS pool, the D7-P5520 makes a lot of sense. If you're building a gaming PC or want something to drop into a laptop, this is absolutely the wrong drive. The endurance is the headline feature, and everything else is secondary.
