About SanDisk

In a world where NAND storage density, capacity, and low cost matter the most, key metrics that take a back seat include endurance and retention rates. For users who want high endurace and retention rates, who want to ensure that their memory cards last for a long time, Western Digital's SanDisk has recently launched its Max Endurance microSD cards that promise increased endurance, reliability, and are covered with a massive warranty.

The SanDisk Max Endurance lineup of microSD cards includes models featuring a 32 GB, 64 GB, 128 GB, and 256 GB capacity. To maximize longevity of the SanDisk Max Endurance devices, they are waterproof, shockproof, X-ray-proof, and can work an extreme temperature range between -25°C and 85°C (-13°F to 185°F).

As far as performance is concerned, the SanDisk Max Endurance cards use the UHS-I bus and are rated for up to 100 MB/s reads as well as 40 MB/s writes. The cards in the lineup support the Video Speed Class 30 spec, therefore offering at least 30 MB/s sequential write speeds. Also, the products carry the Class 10 and UHS Speed Class 3 logos.

Marking a new high in microSD card capacities, Western Digital has started shipping its flagship SanDisk Extreme 1 TB microSDXC card. This is the company's (and industry's) first 1 TB microSD card, and while the $450 launch price is definitely steep, for portable devices that need a massive amount of storage in a thumbnail-sized removable card, a full terabyte is the biggest step up yet.

When it comes to performance, the memory card is thankfully a member of SanDisk's higher-performing Extreme line, so performance isn't too pokey for reading and writing a full TB out of the drive. Formally, SanDisk rates it for read speeds up to 90 MB/s and write speeds up to 60 MB/s when working over a standard UHS-I interface. This works out to roughly 3 hours and 4.6 hours to read and fill the card, respectively. In fact at this point SanDisk is outright bottlenecked by the UHS bus; the card can actually read at 160 MB/s and write at 90 MB/s when used with proprietary hosts that support DDR transfer modes. So microSD Express and its vastly higher transfer rates can't get here soon enough.

Along with its advertised peak performance, SanDisk's supersized card supports video speed class 30, which among other things means that its minimum write speeds need to be at least 30 MB/s. The card also meets the requirements for the A2 app performance class, meaning that it can sustain at least 4000 random read IOPS and 2000 random write IOPS, and supports capabilities such as command queuing and caching.

In the process of assimilating SanDisk, Western Digital has been re-using their hard drive branding on consumer SSDs: WD Green, Blue and Black can refer to either mechanical hard drives or SSDs. The WD Blue brand is used for the most mainstream products, which for SSDs meant SATA drives. The first WD Blue SSD introduced in 2016 used planar TLC NAND and a Marvell controller with the usual amount of DRAM for a mainstream SSD. The next year, the WD Blue was updated with 3D TLC NAND that kept it competitive with the Crucial MX series and Samsung 850 EVO. 2018 passed with no changes to the WD Blue hardware, but prices were slashed to keep up with the rest of the industry: the 1TB drive that debuted with a MSRP of $310 is now selling for $120.

SanDisk's 64-layer 3D TLC NAND is nearing the end of its product cycle, but they and other NAND flash manufacturers aren't in a hurry to switch over to 96L NAND, so it's not quite time for another straightforward refresh of the WD Blue. Instead, Western Digital has chosen to migrate the WD Blue brand over to a different market segment. Now that the WD Black is well-established as a high-end NVMe product, there's room for an entry-level NVMe SSD, and it will be the new WD Blue SN500. This is little more than a re-branding of an existing OEM product (WD SN520), in the same way that the current WD Black SN750 SSD is based on the WD SN720. The SN520 was announced more than a year ago, but as an OEM product we were unable to obtain a review sample. Like the high-end SN720 and SN750, the SN520 and WD Blue SN500 use Western Digital's in-house NVMe SSD controller architecture, albeit in a cut-down implementation with just two PCIe lanes and no DRAM interface.

The SanDisk Extreme Portable SSD is a rugged, pocket-sized drive that connects to new and old USB ports and exploits the size, speed and robustness of solid state storage. It works with Macs and PCs and is available in four models from 250GB to 2TB. It's surprisingly compact, easily slipping into any pocket and the absence of moving parts makes it more robust and tolerant than traditional mechanical drives. The IP-55 rating allows it to shrug-off mild splashes, while the lightness means it can dangle from its short cable without damaging your ports - ideal for laptop workers who have to get up or move around. But it's the speed that really impresses - when connected to a port that supports USB 3.1 Gen 2, like the USB-C ports on a modern Mac, it'll achieve the quoted rates of up to 550Mbyte/s. This not only allows you to quickly backup data, but also easily free-up space to complete projects on a packed internal drive. Indeed it's sufficiently fast for you to use it as active project storage when video editing, say to store common assets or a final render. I strongly believe everyone needs at least one portable drive, and if you value speed, size and robustness, the SanDisk Extreme Portable SSD is a perfect choice. Portable drives are invaluable for backing-up your data, transferring large files or collections, or simply freeing-up space on a full computer so you can get on with your project. I've long-used a collection of portable drives with traditional mechanical hard disks inside as they offer high capacities at a low price. The Western Digital My Passport 4TB for example costs roughly the same as the 500GB SanDisk Extreme Portable SSD, but gives you around eight times more storage for your money. If you simply want to carry round the most data at the lowest price, you can't beat a hard disk.
