This is a topic that we are talking about in another thread but as I see that more users are experiencing this I have decided to post a thread about it. Since the firmware 3.0.0 the Prime 4 screen is jumping but it doesn’t affect the sound but it is very uncomfortable. I’ve downgraded to 2.4 again but it won’t stop jumping. I’ve gone back to the latest version 3.1.1 and it’s still the same. Does this happen to anyone else?
It happens every 15-20 seconds or so.
As reported before in the other thread, I also have those display glitches. My Prime is used for professionnal gigs, weddings etc… and is in mint condition. I use an external Samsung T7 shield 1 to, which is half occupied by very clean flac files, ripped from cd for the main part, and a few 320 mp3 all verified. All my tags are perfect, no error. This ssd is connected in the rear usb3 port and in horizontal display. Stutter occurs whatever the tittle, the format or the length. I use decks 2 and 3, most of the time, 1 and 4 are used by line entries. I do not have database problem, my search is very fast. I’m on 3.1.1 firmware and I always update with usb. Never had a problem with update. My database has nearby 18.000 entries.
have the same situation as in the video, but it does not repeat itself in such short intervals as a friend wrote. My Prime 4 has never left its place in the home studio since purchase.
The Samsung T7 is really not terrible, it is almost catastrophic! He’s top 10/15 the first day, but then… that’s another story.
This external drive is only good for storing: photos, videos, music and various documents, that’s all.
With a Windows PC, performance is more than random, whether in writing or in reading! My god… even my old Sandisk Ultra Flair usb key in 128gb and faster in writing and works better in reading.
For my part, I have a T7 of 500go and a friend has 2 of 1TB and he is having a big problem on one of his disks.
Mine has the same problem as his, there are more than random performance problems, however with my Mac it works well in writing, but in reading it is random (it is very finicky!).
For a transfer of 94gb of music with a Windows, when it works well, it will take less than 7 minutes, when it is not in good working order it will take more than 34 minutes, or worse more than one hour with a little “stopped working” error message with a nice blank page to match.
They are no longer used for reading, but only for data backups.
I bought Crucial MX500 1to that I put in a USB3 box whose price is between 15 and 25 euros and my colleague followed me except that he took 2 Samsung Evo 870. And everything works like a Ferrari .
Yes, buying an internal SSD + an external box will be a little more expensive, but when it’s our work tool, we don’t limit ourselves in terms of budget and quality, which remains very affordable and economical. based on the long term.
In my Prime 4 and Prime 4+ I only have Samsung from the Pro Series range which is certainly much more expensive, but they are really efficient and I have never encountered any performance or stability bugs!
Désolé mais tu racontes n’importe quoi. Tu as eu peut-être des problèmes avec un T7 mais le mien fonctionne parfaitement. Sur CristalDiskMark8, les vitesses en lecture et en écriture sont hallucinantes et égales à ce que font les meilleurs nvme m2 interne. J’avais auparavant, comme toi aujourd’hui, un crucial mx500 dans un boîtier externe USB 3. Entre le T7 et le MX500 c’est le jour et la nuit ! Par exemple lorsque je copie le contenu de mon disque en sauvegarde ça met moitié moins de temps. Les problèmes d’affichages et de sauts de waveform sont dûs au hardware uniquement et certainement au processeur du Prime 4 qui est à bout de souffle, et n’était certainement pas prévu dès le départ pour toute les choses qui ont été rajoutées. Après, accuser les supports tels que des SSD ultra rapides est totalement absurde, vu que le Prime 4 a été construit et pensé avec des ports USB 2 sur le dessus. L’affichage devrait donc suivre, même avec des clés USB 2. Il faut arrêter de se comporter en fanboy de Denon, en excusant tout problème pour rejeter la faute sur autre chose, alors qu’une bécane à 2500 € aujourd’hui devrait fonctionner au minimum pour ce pourquoi elle a été prévue. Les problèmes d’affichages sont une réalité et un problème du Prime4. C’est tout. Et pour finir, ces sauts et autres bugs sont là depuis le premier firmware 1.3, et à l’époque je n’avais pas mon T7 mais des clés usb Axe memory 3.1, les plus rapides. Donc voilà. Sur un pc, si tu joues sans carte graphique, ça rame. Ben là c’est pareil. Le son ne saute pas car il est mis en cache, mais graphiquement ça tient pas la route. C’est encore pire avec des titres très longs, genre compils mixées.
Yes we know… you always know everything and seen everything! 
Except that if you search the internet whether on the Pioneer forum, Denon, the Facebook pages of these different brands, there are many people who complain about these external SSDs with USB drives.
On the other hand, a friend has the Opus Quad and the Prime 4, he saw the huge differences (I am also very surprised that there is no USB-C on the Prime 4+) and moreover it is the same person who encounters the problem with the T7, it is M2 eco, as there are 3 ranges of SSDs with different memory chips “Qvo Series, Evo, Serie Pro”
You have to bear in mind that there is only one USB3 port on the Prime4 (the one on the back) the others are USB2 the T7 range is in USB3.1 and it is advisable to use it in USB-C and not in USB2 which reduces performance and it will be slightly higher in USB3 port, but for the disc to operate at 100% of its performance it will be USB-C to USB-C.
Yes with computer !!! But with media players like RX2/3 and Denon Primes, that’s not it, it’s a whole different story!
Of the number of Prime 4 users around me… they haven’t encountered any audio dropout problems.
On the other hand… Yes! there is 1 or 2 lag in the display of the waveform during playback, but this remains cosmetic and has no effect on the mix or on the audio, like a micro cut!
Mort de rire ! Tu parles pour toi, là ? Sinon on s’en fout du T7 ! Les autres mecs qui ont aussi des problèmes, ils ont pas de T7. As-tu seulement lu le reste de mon message, ou tu t’arrêtes qu’à ce qui t’intéresse ? Merci pour tes conseils sur les ports usb monsieur je sais tout, mais j’ai un bts sn.
Le Prime4 n’est rien d’autre qu’un pc
On le sais Vincent ! Aller je te laisse avec tes problèmes qui date et qui n’ont jamais été résolu et que les autres non pas !
N.B : Vu que tu as tant de problème… pourquoi l’avoir gardé ?
Ton produit était peut-être défectueux ?
Ça me ferai chier d’avoir un PC équipé d’un processeur de tablette (ARM) lol Une tablette est bien trop limité par rapport à un PC, même s’il est vrai qu’elles deviennent de plus en plus performante !
Moi c’est Laurent, mais bon… Tu es peut être à l’apéro depuis un bon moment. C’est bien des réponses de fanboys ça : si y’a un problème, pourquoi tu le revends pas… C’est d’une stupidité sans nom, commune à 4 ou 5 ici, qui pensent que le forum leur appartient. Si tous ceux qui ont eu des problèmes avaient revendu… Bref. J’aime bien discuter avec des gens objectifs qui ont des vrais arguments, mais là, à part ta haine du T7, y’a rien à échanger
As the forum doesn’t translate posts, like Facebook does, here’s the translated version - not my words - direct translation from the post above.
Sorry but you’re talking nonsense. You may have had problems with a T7 but mine works perfectly. On CristalDiskMark8, the read and write speeds are mind-blowing and equal to what the best internal nvme m2 do. I had before, like you today, a crucial mx500 in an external USB 3 box. Between the T7 and the MX500 it’s night and day! For example, when I copy the contents of my backup disk, it takes half the time. The problems with displays and waveform jumps are due to the hardware only and certainly to the processor of the Prime 4 which is out of breath, and was certainly not planned from the start for all the things that have been added. Afterwards, blaming media such as ultra-fast SSDs is totally absurd, since the Prime 4 was built and designed with USB 2 ports on the top. The display should therefore follow, even with USB 2 keys. We must stop behaving like a Denon fanboy, excusing any problem and blaming it on something else, whereas a bike at 2500 € today should work at least for what it was intended for. Display issues are a reality and a Prime4 problem. That’s all. And finally, these jumps and other bugs have been there since the first 1.3 firmware, and at the time I didn’t have my T7 but Ax memory 3.1 usb keys, the fastest. So here is. On a pc, if you play without a graphics card, it’s slow. Well here it is the same. The sound doesn’t skip because it’s cached, but graphically it doesn’t hold up. It’s even worse with very long titles, like mixed compilations.
I’m not a fan since I’m a former dealer who is not commercial for the distribution of all brands at Star’s Music, but hey!
Sorry, I’m diabetic !
Version 1.3 is the date of the product’s release (2019), So… keep a buggy product for Pro use “because the others on the forum aren’t buggy if we listen to you”, you’re the one who’s stupid to keep a product so buggy for 4 years! For my part if I have problems with gear for my Pro use I get rid of it just as soon, I will not moan for 4 years.
Are you sure that you did not sneak this in? What a start to a sentence. 
That was funny.
Lets play nice gents.
That is a very bold statement based on a sample size of 2.
I feel like this thread’s been hijacked somewhat 
I admit that the term catastrophic is pushed lol
I say that because I had never had a problem with X SSD! However, I had a small number of them (Mostly Samsung Serie Pro 830, 850, 860 and Evo 860 and 870) and recently to replace my T7, I bought a Crucial MX500 1TB and that’s why I said it was not a good experience.
On the Denon France page, I counted 7 with random problems and I saw 3/4 of them in the Official Denon page and on the Pioneer forum and some came to complain in the store, because they don’t understand that their SSDs don’t work as they should!
But as I said:
1 - there is surely a compatibility problem.
2 - we can come across a defective product. Especially one that stops for no reason and whose write performance fluctuates. The more I skim through DJ forums using this SSD, there are plenty with random issues with their media players.
To manage this kind of SSD, all our readers would have to be equipped with USB-C and there indeed the complaints would undoubtedly be reduced (especially with regard to compatibility, we do not make a Subaru with a 4L), nothing indicates that using this kind of disk with USB2 ports, it would not damage them, how many people renew their pc or mac, many try to make their computers last and therefore when buying these SSDs this will not be used correctly, despite what users think in priority to the quality of performance of this one and not to the performance and compatibility with their computers.
fyi. I connected the t7 ssd to the SC6000M hub and then connected the player to the PC via usb in order to check the read and write speed. File reading speed was averaged ~350MB/s and write speed was ~280MB/s for the internal and external SSD, which is more than enough for the player to work with music, because the average file size usually does not exceed 100MB
Let me throw a little spanner in.
I have read that the chip used only support 2.0 speeds. My understanding of this is that even though the prime has some 3.0 ports that benefit is for transferring tracks to storage devices plugged into those ports.
This to me means for actual loading and playing of track the ARM CPU reads and writes data at the same 2.0 speed irrespective of the usb one plugs the drive into.
Which means that we will not have performances at are max with the bonuses! Unless… if Google Translate mistranslates your com.
If an SSD or a USB key has write and read performance, this will allow better management of the memory cache of our different readers, whether for loading the contents of the file and emptying the cache of it will only be better, the latency will be incredibly reduced.
it all does not matter as written above, the processor can only work in usb2 mode with external devices (and internal ssd as I understand it too). I just checked how it works through the player’s hub, the numbers when connected to a PC are much higher
