ADATA SD700 External SSD (512GB)

ADATA is no foreigner to a universe of ruggedized, unstable drives. Over a past year or so, a association has expelled a array of engaging expostulate designs meant for being crushed and bashed, trimming from bite-size units with SSDs inside such as a ADATA SE730 External SSDADATA SD710A. With a examination section today, a ADATA SD700, a association is going for a imperishable design, yet with a twist: An SSD, this expostulate uses 3D NAND flash, that is starting to turn a customary memory form in inner drives and was pioneered by Samsung.

The vast understanding with 3D NAND is that it has generally better continuation than a predecessor, planar NAND. That progressing form of memory had chips laid down side-by-side, given with 3D NAND, layers of memory are built on tip of one another in a three-dimensional array, with straight interconnects by a silicon. It’s an sparkling growth in a universe of both inner and outmost storage, in that it has implications for both pricing and portability.

Not customarily is a enclosing on this expostulate rugged, yet on paper a memory inside has aloft endurance, too. On a flip side, a SD700 sports a USB 3.1 Gen 1 interface, that is in all yet name a same as customary USB 3.0. A few newer outmost SSDs out now flourish USB 3.1 Gen 2, that doubles a fanciful bandwidth charity by Gen 1. That said, we haven’t seen a vital uptick in speed to date with a newer USB variant.

In essence, a SD700 is ADATA’s chronicle of a SanDisk Extreme 510, with formal, central ruggedness specs. That, though, is a vast difference-maker. Let’s see why.



Design

The SD700 comes in dual tone options. Both versions have a black center, yet we can select possibly plain black or a nifty fluorescent yellow for the rubber O-ring around a edge.

ADATA claims that a ring provides insurance opposite drops adult to 4 feet. That’s not customarily an idle claim, either; it’s corroborated by a drive’s acceptance for MIL-STD-810G 516.6 military dump testing. From a data-safety perspective, an SSD is always going to be a safer gamble to dump than a tough expostulate from any height. But a rubber circumference here ought to keep a box from cracking, as well.

The expostulate is also waterproof, means to continue soak for adult to 30 mins during inlet adult to 1.5 meters, via a rubber capsule that prevents accession of elements. It’s also entirely stable from dirt or sand. The customarily catch: To make a expostulate retard this things effectively, we have to mislay a USB wire and make certain a stopper, shown below, is in place. Again, there is a customary to behind adult these claims here, IEC’s IP68: The one that indicates a waterproofing is a “8” in a IEC IP68 nomenclature that this expostulate has (the “IP” is for “ingress protection”). The “6” indicates a turn of dustproofing.

ADATA SD700 (512GB) (Connector)

Another good hold is a mouth around a USB pier we can see above. It keeps a wire from flexing during a indicate where it joins a drive, a common indicate of disaster on outmost drives. That is generally appreciated, given how skinny and crisp a total USB 3.0 data/power connector on drives like these tends to be.That said, many newer outmost SSDs have changed to USB Type-C connectors here on a expostulate end, and we consider ADATA should, too.

The expostulate comes in 3 capacities: 256GB, 512GB, and 1TB. ADATA sent us a 512GB indication for evaluation. It comes in a trim wrapping we see above, not many incomparable than a expostulate itself, with a removable cable, a guaranty leaflet, and not many else.

The expostulate is really small, during customarily 3.3 inches block and a half-inch thick. It’s fundamentally a cosmetic block with that rubber ring around it, and if we reward a cable, it’s utterly pocket-friendly. Here’s what it looks like subsequent to a new Apple iPhone, for a distance comparison…

Under a corner strap is the USB Type-A connector we mentioned, that works with a wire that allows it to be connected to any Type-A USB pier (i.e., a customary rectilinear kind). ADATA records a harmony with PCs, Macs, and Android inclination (the last, presumably, tablets with a claim port, or an Android phone connected around an OTG adapter). It’s a tiny ungainly that there’s no resource to store or curb a cable, generally given a capsule over a USB pier has to be in place for a expostulate to offer full protection, and to do that, we need to detach a cable.

When you’re traveling, you’ll wish that tiny doorway to be shut, yet where do we put a cable? Cable storage has always been an emanate with this kind of really tiny drive. We’ve seen a few ruggedized models over a years (usually, hard-drive-based ones) that have stored a wire in a slit around a edge, yet a SSD-at-the-core SD700 is too tiny for that to work.

No program comes in a box with a SD700, yet we can download ADATA’s elementary SSD Toolbox program for monitoring dungeon wear, wiping a drive, and saying expostulate stats. ADATA also offers downloadable utilities for installing an OS from a SSD (OStoGo) and another, HDDtoGo, for subsidy up, encrypting a drive, and behaving several other confidence functions. (You can find a program on this support page.) As it comes, it’s simply a expostulate in a box, and it charity 476GB of storage once formatted in Windows 10. The expostulate is rated by ADATA to broach adult to 440MB per second in examination operations, and adult to 430MB per second in writes, yet there is some slight movement in these ADATA-claimed speeds depending on a specific SD700 expostulate ability in question.

As distant as pricing goes, a ADATA SD700 is aggressively labelled on a cost-per-gigabyte basis. The 256GB chronicle was customarily $99 on Amazon during this writing, while a 512GB chronicle was $189 and a 1TB a healthy $339. Compared to a recently launched WD My Passport SSD, a ADATA is not customarily some-more imperishable yet some-more affordable, as that expostulate was going for about $200 for a 512GB chronicle and around $400 for a 1TB version.

Versus a clearest semi-rugged competitor, a SanDisk Extreme 510, a pricing was close, with a 480GB SanDisk (versus a 512GB ADATA) during $178. That said, a ADATA SD700 offers a aloft turn of insurance than a SanDisk; for example, we can dash H2O on a SanDisk, yet a SD700 can be entirely submerged yet fear of information detriment (for a brief time). The SD700 is also labelled likewise to a Samsung Portable SSD T3, yet it is, again, smaller and tougher. (We customarily got in palm a newer version, a T5; pattern a examination of that Samsung expostulate in a entrance days.)

ADATA includes a three-year guaranty on a SD700. As we remarkable earlier, a box contains only the drive, a USB cable, and a quick-start leaflet. Let’s get that wire bending adult and get enormous on testing.



Performance Testing

Before we burst into a numbers, it’s critical to indicate out that we tested a ADATA SD700 on a desktop storage testbed regulating a machine’s designated USB 3.1 Gen 2 port. (The motherboard is an Asus X99 Strix Gaming paired with a Broadwell Extreme Edition CPU.)

As we mentioned, this expostulate privately supports USB 3.1 Gen 1, that was an in-name-only refurbish to a USB spec that is, in unsentimental terms, customarily USB 3.0. (For some-more on USB 3.1, brush adult during a explainer underline The Basics: USB 3.1 and USB Type-C.) We also reran some of a tests on one of a board’s USB 3.0 ports to see what disproportion that made, deliberation that many users will have entrance to customarily that kind of USB port, not USB 3.1. In short: We saw no differences that were value noting. Below, we are comparing a SD700 to a horde of outmost SSDs we’ve tested over a final integrate of years.


AS-SSD

We started out with AS-SSD, a fake exam that’s geared toward contrast SSDs. We also use this application to exam inner SSDs. First, a consecutive read/write test…

ADATA SD700 (512GB) (AS-SSD Sequential Read and Write)

As we can see from this chart, outmost storage speed has come a prolonged way, given that hard-drive-based unstable drives tend to tip out during a tiny some-more than 100MB per second. As distant as a SD700 goes, it came surprisingly tighten to ADATA’s claims in this worst-case-scenario benchmark. Versus a new rival set we see above, it was indeed a slowest of a drives we’ve tested, yet by margins tiny adequate that you’d expected never notice yet benchmarking program or a stopwatch. It’s roughly able of relocating information during 400MB per second in possibly direction. Interestingly, a expostulate that kick a SD700 by a largest domain in this organisation was a overachieving sibling, a SE730, regulating on a USB 3.1 Gen 2 interface.

In a AS-SSD 4K Read/Write test, that is a magnitude of doing tiny files, many of a drives were clustered tighten adequate to be mediocre in their differences…

PCMark 7 (Secondary Storage Test)

Next is a PCMark 7 Secondary Storage Test, partial of Futuremark’s PCMark 7 contrast suite. This benchmark gives a exclusive measure for any expostulate formed on a array of scripted tasks customary of bland PC operation and hoop accesses. It measures app launches, video-conversion tasks, picture import, media-file operations, and more.

ADATA SD700 (512GB) (PCMark 7)

The SD700 achieved utterly good in this test, racking adult a second-fastest measure we’ve seen in this garland of recent external SSDs. Perhaps a many important feat here was over a recently launched WD My Passport SSD, as both of these drives are 2017-new, and a ADATA is reduction costly and some-more rugged. In integrity to a WD drive, a ADATA drive’s program doesn’t utterly compare adult to WD’s. Also, PCMark tends to exam real-world app performance, yet many users won’t be regulating programs off this drive, customarily regulating it for supplemental storage.


10GB Folder Tests

We afterwards changed on to a real-world exam of shoving pieces around. Here, we charge a expostulate to write and examination a customary brew of record forms vast and small. The source and finish expostulate was a U.2-interface NVMe inner SSD, a Intel 750 Series SSD, to safeguard that a source/destination was not a bottleneck.

ADATA SD700 (512GB) (10GB Uncompressed)

In this test, a ADATA expostulate flip-flopped scores with a SanDisk Extreme 510 and was a smidge faster than a WD My Passport SSD, yet slower than a few of a prior drives we tested, namely a Transcend ESD400, Samsung Portable SSD T3, and progressing ADATA SE730. It mislaid to a other drives by customarily a few seconds, so it wasn’t a drubbing. This creates a expostulate really good for duplicating vast files to a horde PC, yet when duplicating files to a drive, you’ll have to wait a blip or 3 longer than we competence with certain other drives. Again: You’ll see a disproportion customarily in benchamrk tests.

This subsequent exam uses a same 10GB record set as a prior test, yet zipped to a singular vast 7.67GB file. In short, it involves duplicating one really vast record to a drive, afterwards reading it behind as it writes to a host…

The SD700 achieved sufficient here, and a formula were in line with what we saw from a other drives.


2GB Folder Test

Our 2GB Folder Test comprises a garland of MP3 files (in other words, a vast garland of comparatively small, consistently sized files) eliminated from horde to expostulate and behind again…

ADATA SD700 (512GB) (2GB Uncompressed)

The SD700’s examination scores were in line with a best of a pack, while writes were a step behind. But again, we’re articulate here about a handful of seconds. 


Crystal DiskMark

Finally, a Crystal DiskMark consecutive read/write exam is run as a existence check opposite AS-SSD. (For this kind of secondary-storage drive, consecutive operations are a many relevant.) And indeed, we didn’t see many relations disproportion here, detached from a clever display by a WD…

Conclusion

We found a lot to like about a ADATA SD700. Its pattern is sharp and rugged-looking, and a latter isn’t customarily window-dressing. The expostulate itself can withstand drops, water, and sand, and it’s flattering damn fast, too. On tip of that, it’s aggressively priced, and yet it doesn’t embody any backup or other modernized program (just entrance to ADATA’s same simple SSD application it uses for a inner SSDs), many users don’t need many for an outmost expostulate with medium capacity. It would be accessible if ADATA enclosed an encryption apparatus of some sorts, like Samsung offers with a outmost drives, yet it’s not a understanding breaker.

As it stands, a SD700 isn’t a fastest outmost SSD on a market, yet it’s quick enough, in many situations not discernible from competing drives and a outrageous alleviation over regulating a spinning tough drive. The fact that it uses 3D NAND is a bonus, yet finish users won’t notice any poignant opening boost from it. It theoretically should have improved endurance, yet that won’t save your information if a controller or some other inner member dies.

Overall, a SD700 has a lot going for it, yet it falls customarily bashful of an Editors’ Choice collect due to a fact that it’s a rather bare-bones charity that didn’t outperform other portable, outmost SSDs we’ve tested previously. It’s still utterly snappy, though, by a SSD nature, and we adore a imperishable demeanour and insurance opposite a elements. We’d select it over a SanDisk Extreme 510 on dual grounds: We like a form cause better, and a insurance aspects are sterner stuff. If you’re an outdoorsy form or, say, a camera chairman mostly computing out in a weather, and need a expostulate that can dauntless a elements, a SD700 is a excellent choice indeed. It’ll also wear good in your day bag or purse.
