WD Blue 3D SSD (M.2, 1TB)

2012 Editors' Choice Logo

These days, it seems, 3D NAND memory is entrance around for a revisit to each vital builder of solid-state drives (SSDs), and it’s not going home. Now it’s Western Digital’s spin to be host.

WD is throwing a shawl into a ring for 64-layer 3D TLC-based SSDs with a new line of Blue drives. (See a examination of a non-3D chronicle of a WD Blue from a while back.) This form of cost-efficient NAND flash—the core memory chips that make adult any SSD—is a new hotness in a universe of mainstream SSDs, and over a past year we’ve been saying a solid tide of announcements surrounding companies bringing their possess versions to market. WD’s is a latest.

Samsung kicked off a whole 3D-NAND-based disturb with a 48-layer Samsung SSD 960 ProSSD 960 EVOCrucial MX300Intel SSD 545s Series. WD, that also owns a consumer-staple storage code SanDisk, is privately entrance to marketplace with a 64-layer design. The thought of 64-layer in SSDs, in a nutshell, means flattering many what it sounds like: 64 layers of memory built in a three-dimensional space, rather than laid out side by side (in what is called a “planar” design).

This 3D proceed is a radical depart from a planar process of laying down memory dies. Making a chips ever-smaller to fit in a planar intrigue gets increasingly wily as a distance goes down, so 3D NAND development’s idea was to keep a chips during a reasonable size, and usually smoke-stack them vertically. (For some-more on SSD lingo, see a beam Buying an SSD: 20 Terms You Need to Know.)

Besides a spatial problem solved by a inlet of 3D NAND, this proceed has several other benefits, many noticeably increasing continuation (at least, as rated by a SSD makers themselves). In a box of WD (and SanDisk), it places a brands alongside other attention heavyweights in being means to offer a latest record to a SSD customers. For WD’s part, a spokespeople contend a pierce to 64-layer 3D NAND allows it to yield drives with reduce energy expenditure as good as aloft performance, endurance, and capacity, that sounds like a trifecta for a mainstream SSD. [Hey, that’s 4 things! Is there such a thing as a quadfecta? —Ed.] 

WD is also releasing this expostulate underneath a opposite name underneath a SanDisk brand, as a SanDisk Ultra 3D. (See a new examination of a SanDisk Ultra 3D SSD.) That expostulate comes only in a 2.5-inch form factor, while WD is charity a Blue 3D in both a 2.5-inch pattern and in a M.2 “gumstick” form we see graphic here. If you’re some-more of a SanDisk fan than a WD loyalist, we could buy a SanDisk-flavored one, yet according to WD, they are a same SSD underneath a skin/stickers.

WD Blue 3D SSD (M.2, 1TB)

Plextor M8Se.

Therefore, a good news: On a WD Blue 3D SSDs, it’s SATA, so it’s widely compatible. The bad news is, well, it’s SATA, as this means it’ll expected offer a same spin of opening we’ve seen from SSDs for a past 3 years or so. But that’s a SATA problem, not a WD one.

WD Blue 3D SSD (M.2, 1TB) (Module Front)

The Blue 3D NAND SSDs come in 4 capacities: 250GB, 500GB, 1TB, and 2TB. Each ability will accessible in both of a form factors (2.5-inch contra M.2 Type-2280). The drives are specified to broach adult to 560MB per second in consecutive reads, and 530MB per second in consecutive writes, that is tighten to a limit opening probable over a SATA connection, whose tough roof is 600MB per second. Even underneath a perfect-circumstances fake test, SATA drives won’t utterly strike that 600MB per second, due to a magnitude of beyond compulsory in a transfers. Overall, there’s not a outrageous speed disproportion in a genuine universe among well-made, late-model SATA SSDs. But WD’s ratings put it right in a brew with a tip of a lot.

As we mentioned above, one of a biggest advantages of relocating to this form of memory for an SSD is increasing endurance. To know why, we need to comprehend that behind when SSD peep memory was being laid down side-by-side, a usually approach to boost ability was to cringe matters down, and as a elements concerned got smaller and smaller, a intensity for division between cells became a problem. By stacking a layers vertically, SSD makers can widespread out a silicon more, given they’re no longer compelled by a planar orientation. That, in turn, allows a chips to be some-more robust.

In a continuation vein, WD is punishment some considerable numbers. For example, a 2TB expostulate is rated for adult to 500TB of created data, which, depending on what we do, competence sufficient that we could use a expostulate for a rest of your life and pass it down to your kids. The 1TB expostulate is rated to hoop 400TB of writes; a 500GB is rated for 200TB; and a smallest (250GB) expostulate is rated during 100TB. These are all high, as mainstream SATA drives go, and if they vessel out, they should be some-more than sufficient for any mainstream user. (Really, unless you’re day-in, day-out essay outrageous 4K or 8K video files as a pro calm creator, it will be tough to strike these numbers underneath standard usage. The drives themselves will turn archaic in terms of capacity, or passe for other reasons, before then.) Some manufacturers don’t indeed recover these numbers, so it’s transparent that WD is assured in them, by trait of a fact that they are being published.

Software Pricing

Some bill drives come with little (or scanty) software, yet a Blue 3D expostulate includes a flattering decent bundle. It facilities WD’s SSD upkeep software, dubbed SSD Dashboard, that we lonesome in a progressing examination of a non-3D WD BlueSamsung SSD 850 EVOThe Best M.2 Solid-State Drives, Tested. 

AS-SSD (Sequential Read Write Speeds)

This exam uses a AS-SSD benchmark utility, that is designed to exam SSDs, as against to normal spinning tough drives. It measures a drive’s ability to review and write vast files. Drive makers mostly quote these speeds as a fanciful limit on a wrapping or in advertising.

Sequential speeds are critical if you’re operative with unequivocally vast files for picture or video editing, or we play lots of games with vast levels that take a prolonged time to bucket with normal tough drives. We secure-erase all SSDs before using this test.

WD Blue 3D SSD (M.2, 1TB) (AS-SSD Sequential Reads)

The WD Blue 3D achieved utterly good in a review apportionment of this test, reaching a limit postulated send rate of 518MB per second, that is about as many as we can design from a SATA expostulate in this test. As we can see, it was usually a few megabytes per second slower than a fastest drive, with many of a drives clustered close. That’s given this is radically a straight-line speed contest, and many SATA drives with identical specs are in their component for a candid charge like this. Still, it’s earnest that a WD Blue 3D was one of a faster drives we’ve tested.

The expostulate also ran flattering quick in a write apportionment too, holding third place yet entrance tighten adequate to a tip drives to radically call it a tie…

WD Blue 3D SSD (M.2, 1TB) (AS-SSD Sequential Writes)

It was means to strike 492MB per second, which, like a review test, is about as quick as a SATA expostulate can go on this benchmark. It was quick adequate that it was usually 17MB per second slower than a fastest drive. But presumably even some-more poignant is a fact that it tied a reigning mainstream-SSD champion, a Samsung SSD 850 EVO (which, as remarkable earlier, also uses 3D NAND).

AS-SSD (4K Read Write Speeds)

This test, also a partial of a SSD-centric AS-SSD benchmark, measures a drive’s ability to trade little files. Often overlooked, 4K performance, utterly 4K write performance, is critical when it comes to foot speed and module launch times.

When booting adult and rising programs, many little files get accessed and edited frequently. The faster your expostulate can write and review these kinds of files (especially energetic couple library, or DLL, files in Windows), a faster your OS will “feel.” Since little files like these get accessed many some-more frequently than vast media or game-level files, a drive’s opening on this exam will have a larger impact on how quick a expostulate feels in bland use.

WD Blue 3D SSD (M.2, 1TB) (AS-SSD 4K Reads)

The WD Blue tender us once again on this test, entrance in as a second-fastest SATA expostulate of this lot, usually 2MB per second slower altogether than a budget-oriented Toshiba OCZ TL100. More important, it edged out (barely) dual of a categorical competitors, a Samsung SSD 850 EVO and a just-released Intel SSD 545s, despite by margins little adequate to make no obvious disproportion in a genuine world. Regardless, a win is a win, and a WD Blue 3D delivered a clever opening here.

As for 4K writes…

WD Blue 3D SSD (M.2, 1TB) (AS-SSD 4K Writes)

The WD Blue is on a roll, once again roughly atop a benchmark chart. Once a fume had cleared, it was usually a WD Blue 3D and Crucial BX200 on a podium, with a others in a step-down category below. So far, this expostulate is proof rather well-rounded.

Anvil’s Storage Utilities

Anvil’s Storage Utilities is, like AS-SSD, an SSD-specific set of drive-benchmarking tests. We’ll news here a Overall Score, that is subsequent from a Read and Write scores with a application using during default settings. (That is, with 100 percent incompressible data.) The expostulate was secure-erased before a exam was run.

WD Blue 3D SSD (M.2, 1TB) (Anvil)

In this “one measure for everything” test, a WD Blue 3D strike second place altogether by a razor-thin domain to a some-more costly Samsung SSD 850 Pro (not to be confused with a some-more mainstream-priced SSD 850 EVO). Of a midrange and bill drives, though, a WD Blue 3D was clearly a fastest, if by little margins once again. It was also noticeably faster than a previous, non-3D chronicle of a WD Blue drive; this indicates that a new 64-layer TLC 3D NAND in a Blue 3D indeed gains we an uptick in opening over a prior drive. It usually edged out a Intel SSD 545s, that also has 64-layer 3D NAND, by a little some-more than a domain of error.

Crystal DiskMark (QD32 Testing)

Crystal DiskMark uses incompressible information for testing, that stresses many complicated SSDs utterly a bit given they rest on information application to grasp their limit spin of performance. This sold exam is designed to replicate a duties of an SSD located inside a Web server, as it’s asked to perform a smattering of little reads, 4K in size. While it’s reading these files, a reserve of 32 superb requests is lined adult (a “queue depth” 32 requests deep). That’s standard of a high-volume Web server, that has to perform requests entrance in during a same time from several clients.

WD Blue 3D SSD (M.2, 1TB) (Crystal 4K QD32 Reads)

In this perfectionist benchmark, a WD Blue 3D defeated a bit off a roost and was indeed outgunned by a predecessor, a vanilla (non-3D) WD Blue drive. On this test, nobody in this lot outran a Samsung SSD 850 drives, that took a No. 1 and No. 2 spots. The WD Blue 3D still achieved well, finishing usually about 30MB per second behind a fastest expostulate overall, that isn’t too shabby. In any case, this exam is some-more of an educational exercise; this isn’t a expostulate designed for server duty. That said, a write test…

WD Blue 3D SSD (M.2, 1TB) (Crystal 4K QD32 Writes)

In this benchmark, that competence be a many severe exam for an SSD in a whole suite, a WD Blue 3D wanted with a large cats from Samsung and finished usually a splinter behind them. This measure puts a WD Blue 3D during a tip of a store of non-Samsung SSDs, a Kingston HyperX Savage excluded. It’s a clever showing, and it also outpaced Intel’s SSD 545s expostulate again. The many important eminence we gleaned from this exam is a disproportion between this new WD expostulate and a comparison one, that hung out during a bottom of this lot. That’s utterly a difference.

PCMark 7 Secondary Storage Test

Our final exam is a PCMark 7 Secondary Storage Test. This holistic hearing simulates bland expostulate accesses in a Windows environment.

WD Blue 3D SSD (M.2, 1TB) (PCMark 7)

This benchmark illustrates a pivotal law right now in a universe of SATA SSDs: In a genuine world, many leading-edge and mainstream SATA drives perform many a same in bland applications that don’t engage outrageous or visit record transfers. Despite a little differences among benchmark results, many will finish a kinds of tasks attempted by home users in roughly a same volume of time. While it’s positively a good thing that a WD Blue 3D finished “technically” fourth, it’s radically tied with a whole garland of drives on this trial. 


Overall, we’re tender with a WD Blue 3D. It achieved good in flattering many each exam we ran, and it comported itself like a midrange SSD with high-end aspirations. It still doesn’t technically tip a Samsung SSD 850 EVO, yet it’s tighten adequate that underneath many circumstances, it will be indistinguishable. For a normal home user, it’s tighten enough, and it’s one of a few drives we’ve seen of late that achieved good opposite a board, instead of usually in some of a tests. Overall, a WD Blue 3D is a unequivocally rival SSD.

It also includes glorious software. Those utilities tend to be one-time-use, or in many situations not unequivocally required, yet they are good to have. We also like that WD is including a duplicate of Acronis, as it’s a fave of ours among cloning module and corrects one of a shortfalls with a prior drive’s rollout. (Bundling in cloning module is something of a contingency now, to be competitive, so WD indispensable it to hurl with a large boys and girls.)

The continuation ratings are high, too. With a WD Blue 3D being new to a market, we’ll have to see if these continuation claims vessel out over time. But during this indicate in a expansion of SSDs, it’s been years (Samsung SSD 840, anyone?) given we’ve listened whispers of SSD continuation issues. But that is a doubt symbol about any SSD long-term. And that said, a association that loses a play on these numbers will compensate for it big-time in guaranty use down a line, so there is not many inducement to increase them.

Overall, a WD Blue 3D, as we tested it in M.2 trim, is a unequivocally well-rounded package. At launch, it’s not utterly prepared from a cost viewpoint to unseat a Samsung SSD 850 EVO, but, boy, is it close. It checks all a boxes for an SSD for home or business use, and cost fluctuations meant it should be right in a care brew over a life. If prices dump a little bit and someone asks if they should buy this or one of a forms of a SSD 850 EVO (in M.2 or 2.5-inch), a answer is simple: flip a coin.

Or flip an SSD. Label side up, select one; tag side down, a other.
