This compares much favorably to the PNY Elite's 22 MBps. The writes are much better - averaging around 40 - 50 MBps in both the fresh and the used passes. The read performance is close to the claimed numbers and similar to that of the PNY Elite 512GB card. Further justification and details of the testing parameters are available here. This gives an idea of performance consistency (whether there is appreciable degradation in performance as the amount of pre-existing data increases and / or the card is subject to wear and tear in terms of amount and type of NAND writes). Instantaneous bandwidth numbers are graphed. We run the workload on a fresh card, and also after simulating extended usage. We use fio workloads to emulate typical camera recording conditions. For most applications, that really doesn't matter as long as the card is capable of sustaining the maximum possible rate at which the camera it is used in dumps data. In fact, writes can sometimes be much slower.

However, real-world speeds are bound to be lower.

The reader was placed in the Lexar Professional Workflow HR2 hub and uplinked through its USB 3.0 port with the help of a USB 3.0 Type-A female to Type-C male cable. uSD cards utilize the Lexar Professional Workflow SR2 SDHC / SDXC UHS-II USB 3.0 Reader along with the microSD to SD adapter supplied by the card vendor. The USB 3.1 Type-C port enabled by the Intel Alpine Ridge controller that connects to the Z170 PCH via a PCIe 3.0 x4 link is used for benchmarking purposes on the testbed side.

Testbed Setup and Testing MethodologyĮvaluation of memory cards is done on Windows with the testbed outlined in the table below. Prior to taking a look at the performance numbers, we take a look at the testbed setup and evaluation methodology. SanDisk supplied us with a retail sample of their Ultra microSDXC 400GB card to put through our comprehensive memory card evaluation routine. The A1 rating suggests that the card can sustain 10 MBps of sequential accesses, 1500 Read IOPS, and 500 Write IOPS. Compared to the PNY Elite 512GB we reviewed earlier, the main difference is in the A1 rating that guarantees a minimum performance level in non-content capture scenarios (such as usage in smartphones). The SanDisk Ultra microSDXC 400GB is a UHS-I card with a U1 (UHS Speed Class) / A1 (Application Performance) rating. With the industry migrating to 3D NAND, the capacity per die has seen significant increase, allowing for microSDXC cards to reach these capacities. At Computex 2018, we also saw plans from ADATA and Team Group to sell 512GB microSDXC cards. Starting with the 400GB SanDisk Ultra microSDXC UHS-I card ( $94 at $0.23/GB) introduced in August 2017, we now have the Integral 512GB and the PNY Elite 512GB in the market as well. Recently, we have seen a number of high-capacity microSDXC cards getting introduced. SD's popularity and affordability has meant that almost all consumer cameras come with a SD card slot. Currently, the standard and micro sizes are more popular in the market. The cards also come in various sizes - standard, mini, and micro. Its popularity is evident by the fact that it has spawned two follow-ups in the same form factor - starting with the SDSC in 1999 for capacities between 1MB and 2GB, we got SD High Capacity (SDHC) in 2006 (up to 32GB) and SD eXtended Capacity (SDXC) in 2009 (up to 2TB). It gained traction even in areas where CompactFlash had been preferred, thanks to its small size.

SD (Secure Digital) cards were introduced in 1999, as an update to the existing MultiMediaCards (MMCs). We now have the performance numbers for the SanDisk card to enable us to understand the high-capacity microSDXC card market better.

In our series of memory card reviews, we recently looked at the PNY Elite microSDXC UHS-I 512GB, where we had mentioned that the SanDisk Ultra 400GB seemed to be priced much lower on a per-GB basis. However, has now been overtaken by Secure Digital (SD) cards. CompactFlash (CF) became popular in the late 90s. There are different varieties of memory cards catering to various performance levels.

Hand-held consoles and many other computing systems (PCs as well as smartphones) also employ them for augmenting the available storage capacity. Almost all content capture devices employ memory cards (flash-based removable media) for storage.
