PNY LX3030 SSD: Incredible durability for twice the price

This PCIE 3 drive sustains long writes with the top performers and is rated for a staggering 27,000TBW per TB of capacity.

- BY JON L. JACOBI

PNY’S new LX3030 NVME SSD isn’t for everyone. It’s marketed directly at Chia cryptocurr­ency plotting, a very high-bandwidth sustained write task. If you want some info on how much data Chia requires, you can find it here ( fave. co/3e0aqao). But if your workload involves something similar, such as continuous largescale backup, video encoding, or anything else that involves writing lots and lots of data, it might also be of interest.

Why? The LX3030 is the fastest PCIE 3.0–based sustained writer we’ve tested and its TBW (Terabytes that can be Written) ratings are astounding: 27,000TBW per 1TB of NAND. Seagate’s scorching-fast Firecuda 530 ( fave.co/3vs8hyl) is rated for 1,250TBW per terabyte—a lot of data by normal

standards, but shy one zero compared to the PNY’S rated durability.

The catch? When I say the LX3030 is not for everyone, I mean it: The 2TB version I tested is priced at $1,170—more than twice what the aforementi­oned Firecuda 530 costs. Gulp.

PRICE AND DESIGN

The rest of the LX3030 story is rather mundane. It’s a four-lane PCIE 3 drive in the standard 2280 (22 mm wide, 80 mm long) M.2 form factor. PNY was extremely tightlippe­d about details. Peeling back the label, however, revealed a Phison PS5012-12ES-32 controller, eight unknown 3D NAND chips (I found no Web entry for the chip numbers), and two Kingston 1GB DRAM chips.

So why is PNY willing to offer these super-large TBW ratings? To quote the company, “The LX family of SSDS utilize Lifextensi­on technology, a combinatio­n of an advanced AI Engine, LDPC and Flash I/F to deliver ultra-high plotting endurance.” That doesn’t really tell us a lot, but for the record:

LDPC is Low-density Parity Checking; AI is the imitation of human intelligen­ce— completely inappropri­ate in this circumstan­ce so I’ll call it an advanced algorithm; and I/F is simply flash interface.

Just pure speculatio­n: The drive is heavily overprovis­ioned so that more cells are available as replacemen­ts, or as PNY claims, there’s special sauce in the controller firmware and the NAND is super reliable. Or…

Truth be told, price, warranties, and TBW ratings are joined at the hip. Drives that carry high TBW ratings and longer warranties are more expensive because the vendor stands a higher likelihood of having to replace it.

There’s been scuttlebut­t around the industry for years that NAND is far more durable than most ratings indicate. Also, controller­s have become aces at maximizing speed and/or longevity. And it’s a well-known fact that most users don’t write nearly as much data as they think they do. 54,000TBW is writing a 30TB of data every day for the five years of the 2TB drive’s warranty. That’s a lot of data—chia plotting amounts, I’ve been told.

PNY’S TBW ratings in the LX family spec sheet are open to interpreta­tion and don’t exactly match those in other advertisin­g. The 1TB version is covered by the aforementi­oned 27,000TBW, but the warranty is for only two years. The only other drives I’ve seen with higher TBW ratings than the LX3030’S are Intel’s pure Optane SSDS ( fave.co/2xy0vj6), which are even pricier, but rated in the petabytes (!) if you can find one—they were discontinu­ed in early 2021 ( fave.co/3ni8aoi).

PERFORMANC­E

The 2TB LX3030 I tested was strictly mid-tier in its overall performanc­e. Its 3GB writing and 3.4GB reading are very fast (it’s PCI 3 only, remember), but it can’t touch something like the Seagate Firecuda 530 for everyday workloads. If bleeding-edge performanc­e or PCI 4 support are what you’re looking for, look elsewhere ( fave.co/3vs9d8j)— this SSD is about endurance.

This so-so overall performanc­e may well have something to do with the special NAND handling PNY claims is involved in promoting longevity. Rigorous error checking, wear leveling (spreading writes over all the NAND), and finer voltage control might indeed make for slower performanc­e.

The LX3030 was the slowest in the pack in Crystaldis­kmark 6, as well as in our real-world 48GB transfer tests shown below. It’s likely not fair to compare the LX3030 to drives like the Firecuda 530 ( fave.co/3vs8hyl),

Samsung 980 Pro ( fave.co/3pl4afj), or Adata S70 Blade ( fave.co/3jksqpw), but the LX3030 is far pricier than all of those, so we couldn’t in good conscience put it up against budget wonders.

Where the LX3030 took flight was in our 450GB write test. It bested all other drives by at least a couple of seconds. In fact, it turned in the best time we’ve seen over PCIE 3. PNY is apparently serious about the SSD being designed with Chia plotting in mind.

The LX3030 does what it needs to, but of course I’d like to see a PCIE 4 version. Only PNY (and likely Phison) knows if it could pull the superior endurance out of faster transfer rates.

The PCIE 3 tests utilize Windows 10 64-bit running on a Core i7-5820k/asus X99

Deluxe system with four 16GB Kingston 2666MHZ DDR4 modules, a Zotac (Nvidia) GT 710 1GB x2 PCIE graphics card, and an Asmedia ASM3242 USB 3.2×2 card. It also contains a Gigabyte Gc-alpine Thunderbol­t 3 card, and Softperfec­t Ramdisk 3.4.6 for the 48GB read and write tests.

The PCIE 4 testing was done on an MSI MEG X570 motherboar­d socketing an AMD Ryzen 7 3700X 8-core CPU, using the same

Kingston DRAM, cards, and software. All testing is performed on an empty or nearly empty drive that’s TRIM’D after every set of tests. Performanc­e will decrease as the drive fills up. If your drive, given similar hardware, does not perform similarly, please let us know.

BOTTOM LINE

The LX3030 is pricey and then some, so you really need to be sure you’re writing the amount of data that’s required to make full use of its longevity. That’s likely Chia plotting ( fave.co/3vtotzj). If so, then you’ll appreciate the peace of mind the LX3030’S ratings and warranties provide.

Otherwise, look to the far less expensive competing drives shown in the charts, all of which also offer superior performanc­e and plenty of durability, and also support PCIE 4 for future-proofing.
