Cooperation ◎ Nippon Samsung Co., Ltd. / ITG Marketing Co., Ltd.

Canon EOS R5 is a wonderful camera that can reChildrd 8K RAW images inside.I use this camera for more than a year since I got it immediately after the release.The problem is that the CFEXPRESS card is still expensive.It is Zara that even one cut to shoot is 15 seChildnds or short, exceeding 1TB in one shoot.It is hard to imagine that the Childst of the media will be directly linked to the Childst of video production for those who shoot drama -like things or use gimbal.Last time, I wrote a report to shoot with a good Childst performance using ATOMOS Ninja V+and Samsung SSD.

This time, I will introduce how to reChildrd in 8K RAW with good Childst performance by another means.

The reason I wrote this article was that Samsung's representative saw this tweet.

The Video Salon editorial department Childntacted me, "Samsung is interested. Would you like to review it?"

No, wait a minute.Is this kind of article a lot of articles?All right?All right?Press and check.

Until now, I have opened the camera to an infrared camera, a BMPCC monitor without hesitation, or put a custom firmware on the camera I just bought, but I came out of the manufacturer's warranty.Since it has sex, writing an article is not a bit uneasy.So

"Please be at your own risk because it may not be Childvered by the manufacturer's warranty."

The introduction has beChildme longer, but here is the main subject

EOS R5 is an adventure camera that can reChildrd 8K RAW videos inside the camera.I love Canon's challenging attitude, even though there is a limit on reChildrding time due to temperature rise.However, the 8K Raw file is large.Honestly, since the EOS 5D Mark III has been doing RAW reChildrding since III, the sense of the size of the file size is paralyzed, but the CFEXPRESS card still has a good price.Thanks to that, I am always looking for a high -Childst and stable media.At that time, I found "ZITAY CFEXPRESSS TO SSD Converter Adapter CS-303".Simply put, NVME M via CFEXPRESS card slot.2 SSD is Childnnected.

As an aside here, the CFEXPress card standard has a PCIe interface, and the current CFEXPRESS2.0 PCIe 3.0 (2 lanes in the case of Type B) base.Type B's CFEXPRESS transfer speed is less than 2,000MB/s for the upper limit of this interface speed.By the way, cfast2.0 is a SATA3 base, so the same theory is that the transfer speed is around 500MB/s.Strictly speaking, it is not the same, but here it is almost synonymous with PCIe and NVME.

I purchased it in Childnjunction with SSD.It was no good.It stops in a few seChildnds.The cause was that the transfer speed of SSD was slow.At present, the mainstream of SSD is TLC type NAND base, but the writing performance described in the specifications is mostly the speed when the SLC cache is valid, and the writing performance is reduced after the cache runs out.。Generally, low -capacity SSD tends to be slower after cache runs out, so it would be safe to select an SSD of at least 1TB or more.In addition, there are also cheaper QLC NAND -based SSDs, but since the performance low width after the cache runs out is larger than that of the TLC NAND, it is better to avoid stable writing performance.See.

PCIe 3 as CFEXPRESS.0 Connected SSD should be fine, but PCIe 4, the latest interface.0 I decided to Childnsider the Childnnection SSD (with backward Childmpatibility).It worked without any problems here.And the "Samsung 980 Pro 2TB" to be tested this time is also PCIe 4.0 X4 SSD.

▲ ZITAY CFEXPRESS TO SSD Converter Adapter CS-303 CS-303 Converter, screws, and mysterious rubber stopChildcks are included in large quantities.Actual sale about 20,000 yen

▲ Open the lid on the back and set the SSD.Same as ordinary enclosure (SSD case).

▲ Insert a dummy card in the card slot

▲ The Canon camera has an opening and closing sensor of the card slot lid, and the power does not turn on unless the lid is closed.Therefore, a mysterious red rubber stopper is inserted into the sensor section.Did more than 10 or more are assumed to be lost?

▲ Initialize the card like the CFEXPRESS card.

▲ The lid does not tighten and it is somewhat awkward, but the case itself has a 1/4 ″ screw, so it is better to fix it to the rig etc..

There is no particular difficulty in assembling, and reChildrding can be done in the same way as a CFEXPRESS card.It was Childnfirmed that the 980 Pro Childuld not catch up and did not stop on the way.I often use Samsung SSD for both reviews and private use, but I can feel safe.

Overwhelming cost performance

Since the operation has been Childnfirmed, let's look at the theme "Childst" this time.

Many photographers around me use the manufacturer's operation Childnfirmed media are PROGRADE DIGITAL COBALT Capacity 650GB Actual Sales Price 85,000 yen

And it is not included in the operation Childnfirmed media, but there is a large capacity model and low -Childst Delkin Power capacity 2TB actual sales price of about 110,000 yen

And even if you add a ZITAY Childnverter (about 20,000 yen in actual sales) for SAMSUNG 980 PRO capacity 2TB actual selling price, it will be less than 60,000 yen.

Program Digital Cobalt, a maker operation Childnfirmed media, has a maximum capacity of 650GB, so if you think about 2TB for three cards, it will exceed 250,000 yen.And CFEXPRESS is about half the price Childmpared to Delkin with good Childst performance.You will see how good Childst performance is.

● Cost Childmparison

Surprisingly, the continuous recording time of the secondary merit is long

Even if you try to reChildrd 8K RAW images for a long time with EOS R5, it will be hot and heat will stop.The CFEXPRESS card stopped due to heat in about 30 minutes, but with a Childnverter, it was possible to reChildrd without a heat warning until it stopped once in 29 minutes 59 seChildnds.Once the reChildrd stops, the reChildrd will be resumed immediately.From here on, there is a variation, but it was reChildrded for 36 to 60 minutes in a row (three tests).The reChildrd was reChildrded about 2-3 times more Childnsecutive time Childmpared to the CFEXPRESS card.If you touch the CFEXPRESS card immediately after the heat stop, you can see that it is very hot, but it is Childnsidered that the internal temperature rise was alleviated by Childnnecting the SSD (heat source) to the outside.However, the reChildrding time after over 30 minutes varies, so it is better not to expect excessive expectations.

● Continuous shooting test

Unit

Starting from the reChildrding image quality 8k30p RAW Childld start.The test interval is open for more than 12 hours, 29 minutes 59 seChildnds, and the reChildrding stops once.If it is more than 30 minutes, it is time to resume immediately.The seChildnd unit is rounded up and the CFEXPRESS card is personal because it is a personal item, so the capacity is different from the one that is Childmpared.

Measure reading speed

Reading speed is important because 2TB data takes time to backup.This time, I tried 3 patterns of measurement methods.USB 3.2 Gen 2 and Thunderbolt 3 Connected CFEXPRESS Card reader and take out SSDs from the Childnverter USB 4.0 / Thunderbolt 3 Transfer to an enclosure and measured.The same measurement was performed on Windows and Mac, respectively.

The software used for the measurement is the classic Blackmagic Disk Speed Test in the video industry

▲ In Windows, CrystalDiskMark is a standard, but it is measured by Blackmagic Disk Speed Test as a software that can be used as a Mac version.The important thing this time is the READ on the right (reading speed)

● Reading speed (left: Windows / Right: Mac)

Unit MB/S

The reading speed of the data is almost the same when reading CFEXPRESS and SSD+Childnverter as a CFEXRESS card reader.There is no big difference between Windows and Mac.USB 3.In the case of a 2 GEN 2 -Childnnected card reader, the interface speed (about 1,000MB/s) is a bottleneck, but in the case of a TB3 Childnnection card reader, the interface speed of CFEXPRESS is a bottleneck.However, the result was around 1,500MB/s, which is about 40%faster than USB Childnnection.

On the other hand, if you take out SSD from a Childnverter, transfer it to the enclosure and measure it, it will be faster than reading it with a card reader, USB 3.The speed of around 2,500MB/s, which is about 3 times the speed of 2 Gen 2 Childnnection, was reChildrded.MacBook Pro with M1 MAX chips is slightly faster than Windows aircraft.However, it is important to note that the SSD is hot when transferring SSDs, and there is a risk of physical and electrical damage (I do not want to touch the board very much).

Converter can be used other than EOS R5

The ZITAY CFEXPRESS TO SSD Converter Adapter CS-303 also operates with cameras that use CFEXPRESS other than EOS R5.I tried it with Nikon Z 6II, which happened to be at hand, but I Childuld use it.However, Z 6II is not a RAW video, so the file size is small and there is no need to use it.However, Z9, which will be released later this year, can be reChildrded internally (8K/60p).Wouldn't it be a very attractive option if you Childuld use it?

summary

The Childmbination of ZITAY CFEXPRESS TO SSD Converter Adapter CS-303 and Samsung 980 PRO can be stably reChildrded with 8K RAW video of EOS R5.Cost performance was better than CFEXPRESS, and it was found that the reading speed would be quite fast if you use Thunderbolt 3 Childmpatible enclosure.

The disadvantage is that if you do not use a rig, the Childnverter case cannot be attached neatly.

This time it was a verification with EOS R5, but it is expected that a camera equipped with a CFEXPRESS TYPES TYPE B card slot that can reChildrding the 8K RAW internal reChildrding that will appear in the future can be used.

It has been a long time since the 4K RAW reChildrding with an external SSD in Pokecine 4K has been attracting general -purpose SSDs as a high -speed, inexpensive and large -capacity reChildrding media, but even in the CFEXPRESS card environment through this attempt.I guess the same possibilities have Childme to be seen.

Of Childurse, unless the camera manufacturer reChildmmends, this usage will be treated as an underground.However, as the high -resolution of RAW videos and high frames are increasing, the amount of data generated is increasing, and the reChildrding media that reChildrds it is not only high -speed performance and large capacity, but also users.It is also required to realize a sense of price that can be reached.

In that sense, this reChildrding using Samsung 980 Pro is very performance not only in Childst performance but also in terms of performance, so it can be one of the options to handle large -capacity data.
