Pros

• Incredible 10-year warranty and 1,200TBW
• No operation decrease when penning large amounts of data

Our Finding of fact

A very good performer, the 2.5-inch Sony SV-GS46 Pro SSD is also warrantied for 10 years (well-nig others go past out at 5 years) and is rated for 2.5TBW (TeraBytes Written) for all 1GB of capacity. Reassuring, but the drive also costs doubly or to a higher degree the modal 2.5-inch SSD.

So what exactly is a professional SSD, you ask? Take a seem at the Sony G Series Professional SSD's outstanding longevity ratings, and you'll take up your answer. Where the norm mainstream 480GB SSD is rated for around 180TBW, i.e., the number of terabytes that can be shorthand thereto over its life-time, the Sony is rated for a banging 1,200TBW. Throw in a doubly-the-modal 10-year warranty, and yowser! More peace of mind delivered by anything differently Intel's Optane SSDs.

Simply while the G-Series won't set you back as very much like Intel's Methuselah-like Optane, they're more than twice every bit expensive as the average NAND-supported SSD. That begs the secondary question: Do you in reality need that kind of endurance? Not likely if you're an everyday user, just we don't take sports cars, either. That's why the extremely-reliable G-Series makes for interesting reading.

Note: This recap is part of our  roundup of the best SSDs . Give-up the ghost there for details about competing products you bet we tested them.

G-Series specs and features

We tested the 480GB G Series, the SV-GS48 (in stock on Amazon). There's also a 960GB version labelled, yes, the SV-GS96 (also free along Amazon). Both are standard 2.5-inch SATA 6Gbps SSDs, though existence 9.5 millimeters thick probable precludes their use in thin-and-light laptops. But end-substance abuser laptops and PCs are scarce the market that Sony is aiming to conquer; that would personify servers, IT, and data centers.

So how does Sony manage to out-insure everyone? Well, start with the fact that NAND lifespans ingest generally exceeded expectations; add a sprint of particularly robust over-provisioning (keeping extra NAND on hand to replace worn-out cells), and you're a long way toward your answer. Then again, Sony lays the laurels at the feet of civilised error rectification codification. That's some mighty, mighty cypher if it's true.

Only there's too the fact that you're paying a lot more for the G Series than you would for their mainstream counterparts. Checking online, we found the SV-GS96 for round $550 and the the SV-GS48 for around $315—about twice what you'll pay for the homophonic capacity in the Samsung 860 EVO (available on Amazon). And, the EVO is hardly the cheapest SSD along the market. Sony can certainly shrug off replacing the drive given the amount of gain garnered at sale fourth dimension.

Sony

The 960GB Sony SV-G96 SSD is rated for an unthinkable 2400TBW.

Note that other than collateral that the G Series uses MLC NAND, Sony declined to provide any details about the repulse's internals, much as the controller type Oregon whether thither was DRAM cache. Hence, we open it. The controller is Sony-branded, though the last time we checked, the companion doesn't produce its own. The NAND is 15nm 64Gb Toshiba MLC, and there is a 256MB Drachma chip.

Execution

Whether the G Serial SSDs are good deals for you surgery not, they are very good performers, albeit better tuned for server use. Also, because they employ MLC NAND, there's no performance drop-off when writing large amounts of data. Aforesaid drop-off after running out of cache is the hallmark of Tender loving care drives such as the 860 EVO. Synthetic benchmarks don't always reveal the phenomenon, and it varies from model to model contingent the sizing of the cache.

IDG

The SV-GS48 (aureate bars) largely held its possess against Samsung 860 EVO, a popular mainstream drive. Observe that we do non ingest CDM results for the Jamaican capita HyperX Noncivilized that's shown in the other charts. Longer bars are better.

CrystalDiskMark 5, shown above, thought highly of the SV-G48 (gold bars), though not rather as highly as it did of the 860 EVO. But as I said, the 860 EVO will lag a trifle during long write trading operations.

Arsenic you can see below, the SV-GS48 was more than a match for the Kingston HyperX Fierce (no yearner sold, but the quickest MLC drive we've ever tested) with sustained transfers, but fell a trifle short in native (non-queued) 4K operation. The Toshiba TR200 is included to show the low end of the spectrum.

IDG

The Sony proved largely on a par with the competition in the 10GB As SSD 2.0 test. Because AS SSD uses only 10GB of information, the 860 EVO appears better than it actually is during long information writes. Longer bars are better.

In our 20GB file tests (shown below), the SV-G48 threw us a chip of a crook nut with its slow performance authorship smaller files and folders. Perhaps this has something to do with that advanced error correction code Sony talks about. Operating theatre a older controller.

IDG

The Sony had some issues reading our large set of files and folders, but was otherwise quite swift. Small reads and writes are not IT's forte. Shorter bars are improved.

When all is same and done, SV-G48 was weakest with non-queued, non-threaded reduced reads and writes. IT was along a par when those files were queued, or when duple togs were live, as they would be in a server.

Determination

There's absolutely nothing in the NAND-based SATA SSD market that touches the write rating and warranty of the Sony G-Series SSDs. But that peace of idea carries a hefty price tag. Realistically speaking, most PCWorld readers will better off with the far cheaper, and in many cases, equally fast mainstream models.

IT and the enterprise, then again, should be intrigued. It's relaxing not to have to worry about whether you've exceeded your guarantee or drop a line ratings for and lengthened period.
