Silicon Power microSD Card: How good is this new 1 TB card?

Silicon Power microSD Card

After the Sandisk Excessive 1TB and the Micron C200 1TB reminiscence card, Silicon Power has unleashed its first 1TB microSDXC reminiscence card forward of larger names resembling Kingston or Samsung. The storage product is a part of the corporate’s Superior model and is barely the sixth card of this capability accessible in the marketplace.

Pricing and availability

Silicon Power sells this 1TB microSD card (SP001TBSTXDV3V20SP) on Amazon for a mere $169.99 with free delivery within the US and delivery and import charges relevant to different locations.


The microSD card comes with a 5 12 months guarantee and is keeping with the producer, waterproof, shockproof, and X-ray proof. Rated at UHS Pace Class 1 (U3) and UHS Video Pace Class 30 (V30), the Superior microSDXC UHS-I card claims to hit learn and write speeds as much as 100MBps and 80MBps, respectively, with minimal random learn of 1,500 IOPS and random write of 500 IOPS which explains its A1 classification. 

Notice that Silicon Power says that merchandise incompatible with the us1 interface will see their learn/write speeds drop dramatically, right down to around 20MBps within the latter case.

Like all the opposite 1TB playing cards in the marketplace, the Superior will probably make use of a 96-layer QLC (quad-level cell) NAND expertise from WD or Kioxia with a computerized error correction code (ECC) operate.



Right here’s how the Silicon Power 1TB microSD card carried out in our suite of benchmark exams:

CrystalDiskMark: 1041MBps (learn); 999MBps (write)

Atto: 994MBps (learn, 256mb); 987MBps (write, 256mb)

AS SSD: 908MBps (seq learn); 864MBps (seq write)

AJA: 832MBps (learn) ; 850MBps (write)

We examined the Silicon Power 1TB microSD card with a Startech MicroSD card reader on our Dell Latitude 7490 laptop computer. Keep in mind that efficiency will usually rely upon what card reader you utilize, so we didn’t use the laptop computer’s embedded card reader.

The cardboard comes with a none software program – there isn’t a knowledge restoration software program like with Sandisk – and formatting it to the exFAT file system leaves us with a 931GB usable disk house. We additionally suggest that you just use cloud storage or cloud backup service to maintain your knowledge secure.

In comparison with the two different 1TB microSDXC playing cards that we have now examined, Silicon Power got here out barely worse on some and barely forward on others. It scored the very best Crystaldiskmark learn to rate at 93MBps compared to 92 and 90 for its rivals. We had been stunned by its comparatively low actual life file switch speeds, which fell beneath 58MBps compared to 71MBPs for Sandisk.

The competitors


We approached a significant reminiscence card producer to investigate the comparatively low variety of 1TB microSD playing cards in the marketplace, and a spokesperson supplied us with the next assertion.

“Excessive-capacity microSD card manufacturing faces some dimensional challenges as a result of the card’s small floor space (15x11x1mm). To succeed in increased densities resembling 1TB, the entire die essential to hit this capability should match inside this floor space, whereas there are additionally stacking restrictions to contemplate. That mentioned, manufacturing is restricted by size, width, and peak restrictions. Along with the die, a controller and different componentry are additionally required to be mounted to the substrate earlier than being encapsulated to provide the ultimate product, which should adjust to our strict high quality and efficiency necessities.”

There are five different microSD reminiscence playing cards with a 1TB capability at the time of writing. Three of them are extensively accessible: two from Sandisk (the Extremely and the Excessive) and one from PNY. All of them are far costlier than their Silicon Power alter ego. The Micron C200, which we reviewed again in 2019, is, unfortunately, lacking in motion.

We’ve got probed Samsung, Netac, Patriot, and Team group to search out their plans for 1TB microSD playing cards. The latter has the most cost-effective 512GB microSDXC card in the marketplace, one which prices beneath $55 or $110 per TB (and a 40% low cost on the promotional worth).

For these searching for the quickest 1TB microSDXC card, there’s the Sandisk Excessive Professional; it’s far costlier, at $400; however, it virtually doubles the learn speeds 170MBps and is quick sufficient to file at 8K decision. You will have an appropriate reader to take advantage of out of it, although.

Closing verdict 

The distinctive promoting level of the SiliconPower Superior 1TB microSD card is its worth. At lower than $170, its recommended retail worth is already cheaper by a minimum of 15% compared to its nearest competitor. It’s not considerably slower than its rival though it doesn’t provide a lifetime guarantee or a software program bundle. However, these are compromises that many, we really feel, will gladly settle for in change for a slightly sizable saving.

Remember that this isn’t a reminiscence card designed for high-endurance use circumstances like 24/7 surveillance at an excessive decision. That falls beneath the remit of Silicon Power’s new Golden Collection superior household, which sadly, at the time of writing, solely affords as much as 256GB capacities.

NAND reminiscence’s falling costs signify that we could be considerably cheaper 1TB microSD playing cards over Christmas and into subsequent 12 months. One factor we received’t see for the foreseeable future will likely be even increased capacities, partly due to the actual bodily obstacles to, properly, placing extra issues in one thing that small (see the boxout elsewhere on the web page for extra).

As for a budget 2TB microSD playing cards you often encounter on Want, Amazon, or eBay, they’re 100% licensed fakes that you’ll buy at your individual danger. We don’t anticipate to see microSD playing cards greater than 1TB till a minimum of 2023, if ever. 5G and 6G, in addition to ubiquitous quick Wi-Fi, signifies that, for lots of customers, the onboard storage they’ve on their laptops or smartphones is a lot sufficient, particularly if they’ve, say, a Google One or a Microsoft Onedrive account.
