ADATA Legend 860
The 2TB ADATA Legend 860 hits 6000 MB/s reads and 5000 MB/s writes over PCIe Gen4 x4, using SLC caching and HMB to keep load times snappy despite its DRAM-less design. Its bundled heatsink and LDPC error correction support stable sustained performance, and it fits the PS5 expansion slot alongside Intel and AMD platforms. This drive suits budget-conscious gamers and console owners who want a large, fast Gen4 upgrade without paying premium DRAM-equipped prices.
Snapshot
The 30-Second Version
The ADATA Legend 860 is a solid 2TB Gen4 drive with 6,000 MB/s reads and a PS5-ready heatsink. Speed is good, but endurance is a real weak spot. Worth buying for gaming and everyday use, not for heavy write workloads.
Pros & Cons
Pros
- 6,000 MB/s reads and 5,000 MB/s writes for a mid-range price 79th
- 2TB capacity gives you real breathing room for games and media 78th
- Included heatsink makes PS5 installation painless 76th
- HMB support keeps everyday responsiveness decent without onboard DRAM 69th
Cons
- Endurance is a weak spot at 14th percentile
- DRAM-less design struggles under sustained heavy writes
- Random performance is just average
- Feature set is thin compared to pricier Gen4 drives
The proof
Performance
Sequential reads at 6,000 MB/s and writes at 5,000 MB/s are right where a mid-range Gen4 drive should be. You'll load games fast, boot Windows in seconds, and move large files without wanting to throw your monitor out the window. Random performance lands at 59th percentile, which is about average, so don't expect snappy database work or heavy multitasking magic. The SLC cache helps with bursty writes, but once it fills up, speeds will dip. That's normal for DRAM-less drives. The heatsink keeps thermals in check, which matters if you're running sustained transfers or stuffing this into a PS5 with limited airflow.

vs Competition
Stacked against the Samsung 990 Pro or WD Black SN850X, the Legend 860 is clearly a step down. Those drives hit 7,000+ MB/s reads, have DRAM, and crush this thing on endurance. But they also cost more. The Micron T710 and Crucial T710 sit in a similar performance band to the Legend 860, but with better endurance ratings. If you can find one of those for a similar price, it's probably the smarter buy. The Lexar NM1090 PRO is another option that trades blows here. The Legend 860's main edge is the included heatsink and PS5-ready form factor, which saves you a few bucks if you were going to buy one anyway.

Price
Value & Pricing
At $270 USD for 2TB, this drive is priced like a budget-friendly Gen4 option, and for most people it delivers. You're getting PS5 compatibility, a heatsink, and speeds that'll make any game load fast. But the endurance numbers give us pause. If you're just gaming and doing normal desktop stuff, the value is there. If you're editing video or running a database off this thing, you'll want something with better write endurance, even if it costs more.

Overview
The ADATA Legend 860 is a 2TB PCIe 4.0 drive that hits 6,000 MB/s reads and 5,000 MB/s writes. That puts it in the upper-middle tier of Gen4 drives, not the fastest thing out there but way ahead of anything Gen3. It's DRAM-less, which keeps costs down, and leans on HMB to stay responsive. The included heatsink is a nice touch if you're dropping it into a PS5 or a tight desktop build.
Our database puts this drive at 78th percentile for capacity and 75th for speed. Solid numbers. But the endurance score is rough, 14th percentile, and that's the thing you'll want to think about if you're hammering this drive with heavy writes. For everyday gaming and general use, it's probably fine. For a workstation that's constantly moving big files, maybe not.
Common Questions
Q: Does this drive work in a PS5?
Yes. The Legend 860 fits the PS5 expansion slot and the included heatsink meets Sony's thermal requirements. You'll see read speeds up to 5,000 MB/s in the console, which is plenty for fast game loads.
Q: What are the actual read and write speeds?
Sequential reads top out at 6,000 MB/s and writes at 5,000 MB/s on a PCIe 4.0 platform. On PCIe 3.0, expect around 3,400 MB/s reads and 3,000 MB/s writes.
Q: Is the lack of DRAM a problem?
For most everyday tasks, no. HMB uses a slice of your system RAM to keep things responsive. But under sustained heavy writes, like large video exports, you'll notice slowdowns once the SLC cache fills up.
Who Should Skip This
Skip this if you're doing serious content creation, running a database, or anything that involves constant large file writes. The endurance rating is one of the lowest we've seen in this category, and a DRAM-less design will choke under sustained load. Spend a bit more on a WD Black SN850X or Samsung 990 Pro if your data matters that much.
Verdict
This is a decent drive for gamers and everyday users who want 2TB of fast Gen4 storage without spending flagship money. The PS5 compatibility and included heatsink make it an easy drop-in upgrade. Just know what you're getting: good sequential speeds, average random performance, and endurance that's not built for heavy write workloads. If that sounds like your use case, go for it.
