Anyone know anything about the "cache" that was added in the new 8.4 firmware. I have a "Hyperdeck Studio 4K Pro" which now shows a new "No Cache" text on the monitoring output. The updated manual says "For HyperDeck Studio 4K Pro models with optional cache you can choose to turn the cache on
or off via the record menu.". Looking in the device's menu it is greyed out, so presumably I need to install a cache disk first. There is no obvious slot or access panel for it, so presumably this is an internal lid-off job?

I am probably wrong, but isn't it possible that the "cache" would be any local media if you're using a NAS as your main storage? In other words, if the network gets bogged down for whatever reason, it uses SD cards as a cache. I'd love to find out, as I'm a bit leary about recording directly to my Resolve server without a backup.

I've since discovered via a Discord server I am on, that there is infact an internal NVMe slot on the unit's mainboard. You need to remove the lid to access it. You can apparantly record directly to it when there is no other media present in the front of the unit.

Why would that not be documented? Did it say what specs the NVMe can have? Many NVMe drives can store faster than an SD card, so I wouldn't have had to buy Pro Grade SD cards, which cost an arm and a leg.

I've not found any documentation yet on compatibility.

And to be clear, this was another user who was equally curious and decided to pop the lid off their unit to find out.

The 4K was only upgraded to use the Cache a couple weeks ago, still the manual is dated April '24, don't know why there's basically zero mention of cache . The approved drive list (for 8K) is hiding on the tech specs page for the hyper deck extreme, this manual also has more information on the cache disk.

If you look in the manual in the communication protocol section (HyperDeck Manual, April 2024), there are tons of mentions of the cache, where you can get the status of it, whether recording to cache is enabled, etc. No mention of the fact that the cache is actually an NVMe slot. hah

And if you rearrange the letters in the manual the word cache can be spelled 1698 times. Point being is that there's basically no information about location, type, function, etc., The Rest API is neat but it doesn't give any information RE: cache outside of the control protocols which are the same for all machines.

Good Luck

Doug of DJP has done a video on it...

I have recently purchased a HyperDeck Pro within the last month and interested in getting the cache functionality. I watched Doug’s video and attempted case removal to install but it appears that there is a sticker which would need to be removed which suggests that doing so would violate the warranted. He doesn’t reference that so don’t know if that is a recent change? Anyone else attempted this upgrade?

From what I can recall when doing my own unit, it's not a tamper-evident sticker, and you only need to gently lift one corner of it to get to the screw. I actually left that screw out during reassembly to save from disturbing it again in the future.

Also, given their own product page for the HyperDeck states...

HyperDeck Studio is easily repairable with each card slot using an individual PCB assembly that can be replaced if it ever becomes worn out from heavy use.

...I would surmise that the device is considered to be user-serviceable and that lid removal is to be expected.

I just did 4 of them. Just lift the corner of the sticker up with a razor blade and you can access the screw. When it all goes back together you can not tell you ever took it off.

I asked BMD support because recommended disks list not mention M2 internal ssd:
"This would need to be Gen 3 x4. We would recommend the Samsung 990 Pro."

I'm a little surprised because this disk is known to have a low internal cache, so not ideal when you want constant speeds. But if the support validates it

what disk size do you choose?

I have been using the following drive, with zero issues...

Samsung 980 PRO 500GB M.2 PCIe 4.0 NVMe SSD/Solid State Drive
https://www.scan.co.uk/products/500gb-s ... write-800k

I get approx. 90 minutes of cache capacity. (2160p50 Prores LT)
