WD Blue 3D NAND SATA SSD review: One of the fastest TLC drives you can buy - willisoures1963

At a Glance

Expert's Rating

Pros

• No loss of sustained write speed as with other TLC SSDs
• Excellent price per gigabyte
• Available in 2.5-inch and M.2 descriptor factors

Cons

• Oil production label pattern could put off Personal computer enthusiasts who care to show remove their hardware

Our Verdict

The Blue-blooded 3D SSD is the first Tender loving care NAND drive whose sustained write performance nearly matches that of MLC NAND drives. Along with its Sandisk 3D Extreme sibling, by faraway the best bang for your sawhorse in a SATA SSD.

The WD Strict 3D SSD is a SATA SSD with a not-so-inward couple: Sandisk's Ultra 3D SSD. They are in fact the cookie-cutter labour with different labels, WD owning Sandisk and all that. The '3D' term means the drives use stacked (layered, vertical, etc.) NAND. Practically speaking, that means more storage in less horizontal space.

The sole real differences between the drives are the external appearance, the marketing, and the fact that the WD Puritanical 3D ships in the M.2 form factor in, while the Immoderate 3D does not. Beyond that, they're peas in a pod. Given their superior performance compared to other TLC NAND drives—that's a really good thing.

Design and capacity

Though available in the 2.5-inch forg factor, WD sent us the M.2 2280 (22mm wide/80mm seven-day) Blue 3D, which is handy for upgrading laptops or desktops that feature an M.2 slot. It's SATA, not NVMe—just to be clear. Be predestined to check which flavor your M.2 expansion slot is before you buy. Just FYI, NVMe is a lot faster.

The Blue 3D is getable in 250GB, 500GB, 1TB (the size we tested), and 2TB capacities, which sell for $95, $165, $310, and $620 respectively. Those are the prices from WD's site—you may find them cheaper at Amazon, Newegg, or like.

The Downhearted 3D is warrantied for three years and rated for 100TBW for every 250GB. That means WD expects you can write 100 terabytes to the drive before experiencing any loss of capacity due to wear and tear on the cells. If you do the math, that's actually a heck of a lot of writes. Probably more than 10 years' worth for about users. And TBW estimates are generally very conservative.

WD

We tested the 1TB version of the WD Blue 3D, not the 500GB edition shown, merely we liked what we sawing machine from out benchmarks.

Note that the 250GB edition is rated slimly slower than the otherwise capacities. That's common with most drives of 250GB or less, which near often have fewer chips to outspread data across.

Surprisingly good performance

We examine SSDs using both artificial benchmarks, principally A SSD and CrystalDiskMark, and real-populace copy tests.

We're happy to report that somehow, to the gain of users everywhere, WD/Sandisk has managed to create a Tender loving care drive that pot sustain 450MBps performance during long-wool writes. Up hitherto, about the fastest sustained spell speed we've seen out of a TLC drive after information technology oversteps it's cache is 300MBps. Indeed, after testing with our usual 20GB data correct, we threw 320GB at the Blue 3D, and IT just soldiered happening at a steady 450MBps. There may be a point at which the drive will slow down, but we didn't see it.

By manner of compare, the Samsung 750 EVO drops to 300MBps when it runs tabu of cache, was considered skilled. Some drives, so much as OCZ's Trion 100 and even Toshiba's current TR200, drop to around 100MBps—slower than disk drive speeds. Yowser.

CrystalDiskMark tests the SSD with all caching in use and is generally a good indicator of real life performance. We run the test with 1GB, 5GB, and 32GB data sets.

IDG

The differences between these three drives are minimal, not unexpected apt that the Sandisk and WD are actually the selfsame screw different organise factors.

Note that the Crucial BX300 (red bar in the graph above) is an MLC NAND-founded drive. from which we nearly ever see 450MBps to 500MBps authorship simply because writing MLC's two bits takes less time than TLC's three bits. At to the lowest degree until now. The WD Northern 3D (blue bar) and Sandisk Ultra 3D (yellow bar) keep up with it nicely.

IDG

The Equally SSD test results show the Samsung 750 SSD looking a little slow.

The AS SSD benchmark issues the FUA (Force Unit Access—disabling caching in units that admit the command) and is specially profitable in determining the bare-knuckle performance of the controller and NAND. We run both Arsenic SSD's 1GB and 10GB tests, quoting the 10GB try results. As you give the axe see in the chart shown above, the WD Low 3D and its Sandisk Ultra 3D twin mirror each other closely, and keep astir with the Crucial BX300. They all clear the well-regarded (just high-priced) Samsung EVO 750 SSD appear moderato.

Our veridical-world tests comprise of reading and writing some a 20GB single compressed archive and a 20GB set of small- to mid-sized files and folders, with the majority of the files organism compressed types much as WMV, MP3, and JPG. The real-world copies can, and have, revealed issues like the slow sustained write speed of Tender loving care that synthetic benchmarks can sometimes miss.

IDG

Only a few short months ago, the Samsung EVO series was the bomb calorimeter in the first appearance-spirit level market. At once it's slower than the Crucial BX300, Sandisk Ultra 3D, and WD's Wild blue yonder 3D.

For us, the great thing some the evolution of TLC functioning is that once again, we can recommend connected damage without constant disclaimers concerning poor sustained compose performance. For the consumer, it means large-capacity 2TB SSDs with great complete-around performance.

A good deal

We have nothing negative to say about the WD Blue 3D. Okay, the label is boring, which isn't trivial if you're building your have PC and want to flash all your ironware finery through with the tempered-glass, LED-lit side of your case. But IT's fast, affordable, and available in up to 2TB capacities, and we'rhenium impressed with any trick Sandisk/WD wont to eliminate the MLC/TLC performance breach.
