EgoDisk seems to be a new name in the flash memory space, but seem to be making a name for themselves fairly quickly. Looking at their website, they seem to be focused on faster storage media — primarily internal and external SSDs, PCIe m.2 NVME SSDs, CFast 2.0 cards, and even promising offerings such as RED Mini-Mags.
Previously I ordered a KomputerBay CFast 2.0 card for use in my Canon 1DX Mark II, which turned out to be a dud — It often would not be recognized by the camera, and required multiple eject/re-insertion and formatting for it to show up and be usable. Additionally, the card did not seem to perform to its spec, and many buyers have reported lost data and/or dropped frames as a result. Fortunately, in my short time with it, I didn't suffer any data loss, but the spotty reliability ultimately forced me to return the card.
I'd never heard of EgoDisk before browsing a thread on hasselbladdigitalforum.com that mentioned it; only one user had a report (which was positive). Up until I discovered these cards, I only owned the 64GB SanDisk Extreme Pro that came with my 1DX Mark II Premium Kit and I sorely needed both a bigger card (for 4K video and large RAW files from the H6D), and another card for backup, but CFast cards being a new (and extremely fast) storage media, are very expensive right now. So, I took a chance and ordered one of these EgoDisks from Amazon. Being a relatively new (to me, at least) company and having limited success with off-brand memory cards in the past, I was a bit hesitant to try another no-name brand, but the EgoDisk CFast 2.0 card I ordered really did deliver.
Price-wise it's incredibly attractive — as all off-brand products are. It was $289 for a 256GB CFast 2.0 card — which is in-line with other brands such as Delkin ($299 for a 256GB Card). As an aside, I've had success with Delkin cards in the past, and would recommend them. I just wanted to try out a new brand, as they looked very promising.
For comparison, name brand cards such as SanDisk and Lexar offerings in this size cost anywhere from $580 to $680 dollars, depending on their rated performance. That's over double the price! Even Transcend, another respected off-brand card like Delkin — costs $480 for a 256GB card. This makes the EgoDisk an attractive proposition.
Since EgoDisk is a new company, it's unlikely that their cards will show up on any "approved" or "compatible" list of cards for cameras that use CFast media. The EgoDisk CFast cards are being advertised as compatible with BlackMagic Ursa cameras, which use this type of storage media:
It's entirely possible that the cards will work with all cameras that currently use the media, but sometimes the cameras may not like or recognize a card above a certain capacity and simply not work at all, so it's always a good idea to check and test the compatibility with your own equipment.
Fortunately, the card works beautifully with all of my cameras that can use it, and actually is more reliable in the Hasselblad than the other SanDisk card I own, which appears on the H6D's list of compatible cards.
Most cards do not achieve their rated speed(s) in real-world use, but are plenty fast for our purposes. It's unlikely that most people will hit the limit of their cards (except for most video applications — If you're doing video, getting the fastest card you can afford will ensure you don't have any issues with dropped frames or other issues; for stills, it's usually not a big deal unless you are shooting large bursts of RAW files to your cards routinely).
Since many cards tend to be "overrated" in terms of their specs — and the no-name manufacturers seem to be the worst offenders of overinflated speeds — I decided to run some benchmark tests on the EgoDisk versus the SanDisk card that I own, to see just how it stacks up to a well-known brand:
The benchmarks show that the EgoDisk compares favorably against the name-brand SanDisk, and actually beats it in all of the tests except 4K read tests where it barely trails behind — likely an imperceptible difference. The 4K write speeds are double or triple that of the SanDisk, with sequential read and write being markedly better, as well.
In my short experience with the EgoDisk CFast cards, I'd highly recommend them. They deliver excellent price to performance, and seem to be compatible with a wide variety of cameras that take CFast 2.0 media. At the price, you can't go wrong, and i've already received responses from them regarding questions about their product, so their support seems to be good as well.
The only unknown at this point is their reliability, which, if something goes wrong (or maybe even if they continue to function as well as they have so far) — you'll hear about it here. On the upside, the cards do come with a 3-year USA warranty, so that inspires a lot of confidence.
