1920x1080@30p(yuy2)だと

　1920x1088x1.5x30‎ = 94,003,200bps

1920x1080@60p(yuy2)だと

　1920x1088x1.5x60‎ = 188,006,400bps

FullHD(2K)はUSB2.0で、だいたいイケそうだろう。

3840x2160@30p(yuy2)だと

　3840x2160x1.5x30‎ = 373,248,000bps

3840x2160@60p(yuy2)だと

　3840x2160x1.5x60‎ = 746,496,000bps

4KとなるとUSB2.0では危ういときがありえるので、USB3.0でかつ実測値で見るのがよいだろう。

Здравствуйте, мои уважаемые друзья и подписчики!

Недавно я рассказывал Вам о том, что приобрел диктофон фирмы Philips DVT2000. Мы вели разговор о комплектации и о некоторых основных функциях и назначениях диктофона. Также я показал, как улучшить качество записи на диктофоне. Но одно дело - записать на диктофон аудиофайлы, а другое - как записанные аудиофайлы, перебросить на компьютер для их обработки. В видеоуроке я расскажу Вам не только о том, как «скинуть» аудиофайлы на компьютер, но и как с компьютера перенести файлы на наш диктофон. Надеюсь, что информация будет полезной для Вас.

Желаю Вам и членам Ваших семей здоровья, добра и всех благ!

مُميزات كل من USB 2.0 و USB 3.0: ما هي الفروقات وأيهما الأمثل لاحتياجاتك

يلعب USB دورًا حاسمًا في تجربة الاتصال ونقل البيانات. حيث أنَّ USB هو المعيار المقبول لمُشاركة البيانات بين الأجهزة الطرفية والكمبيوتر. ومع ذلك، فإنَّ بعض الشركات المُصنِّعة للأجهزة لا تلتزم بمعايير ألوان USB، مما يجعل من الصعب تحديد نوع USB الذي تستخدمه. لحسن الحظ، هناك طرق مُتعددة يُمكنك من خلالها معرفة السرعة الحقيقية لمنفذ USB، بالإضافة إلى ما إذا كان يدعم معيار USB 2.0 أو USB 3.0. تهدف هذه المقالة إلى إلقاء الضوء على الاختلافات الرئيسية بين USB 2.0 و USB 3.0، وتوفير تحليل شامل للمُميزات والأداء. سنتناول كيف يمكن لهذين المعيارين التقنيتين تجربة نقل البيانات وشحن الأجهزة، وكيفية تحديد الخيار الأمثل بناءً على الاحتياجات الفردية. تحقق من كيفية إصلاح مشكلات الشحن عبر منفذ USB-C على الكمبيوتر المحمول بنظام Windows.

MEIKO (Leo/need VIRTUAL SINGER) Third Senpai ★★★★ (Untrained) (Set: Don't Let Doubts Hold You Back!)

[where-i-bitch-about-nashville]

how far is too far

to take this old socket 423 motherboard? it’s really only limited by the boot drive speed and the cpu cooling/fans at this point, it’s nearly maxed out

so socket 423 was the oldest Pentium IV stuff, though it may have supported some celeron chips if i’m not mistaken. The fastest cpu was 2.0GHz with 400MHz RD-RAM bus with 256KB of L2 cache.

What I have was someone’s rejected server board from 1999 that I got used in 2000 or 2001 maybe, and this has been its third refresh 😅 but for the slowest most uncommon p4, it is great, it has ATA100 RAID and that can mean using up to 4 drives as one for more speed or redundancy.

it has irda for some infrared data, several old school serial ports, parallel, AGP 4x, and 5 PCI ports.

I had already given it 2GB of ECC RAM, some multiformat DVD burners (one sports DVD-RAM support), a 3.5” floppy, and even a SATA soft RAID PCI card,

but I am questioning now that SSD’s are cheap, whether 4 SSD’s would be faster over 33MHz PCI soft RAID or ATA100 hardware based RAID at the full 100MHz ? maybe this thing would be seriously fast, for what it is

I also learned that AGP 4x was as much real bandwidth as any GPUs of the era ever could saturate since AGP8x didn’t last long before being replaced by PCI-express 2.0 16x slots for most GPUs… So AGP 8x cards work just fine here.

I found a GeForce 7600 GS 512MB model that needed recapped, amd so I havent tried it; then i found an ATi HD 3650 512MB AGP8x GPU to try in the meantime. Originally in 99 or 2000 this box was rocking an ATi All-In-Wonder Rage 128 card, but I foolishly gave it the ATi All-In-Wonder Radeon 8500dv for the greater 64MB vram and a couple firewire 1394a ports. It was a fine card, but analog TV is gone, rendering the tuner useless, and the A/D/A converter quality was actually pretty bad on this card with a lot of extra noise added on anything you plugged in. Once I got a miniDV camcorder I just used its converters foe everything, as it looked so much better!

I also got it with a Creative Labs SoundBlaster Live! 5.1 card, which was super cool at the time, but until I had any 5.1 speakers to use it with, it was pointless versus the nearly-identical 2-channel onboard AC’97 chip, or the other nearly identical AC’97 chip on the Radeon card! I wasnmt even bright enough to disable the onboard audio in the BIOS, at the time so I was always doing some dumb routing and wasting resources on all 3 sound cards

Then I did something even more dumb later on and got a GeForce MX420 card with the same 64MB vRAM but less rendering capability than the Radeon card at the time. (As I understand it now, these were more of a display adapter than a GPU?)

I’ll try to remember to benchmark these options against one another at some point, bc i have a feeling the GPU and boot drive is going to make all the difference in the gaming performance

Beyond all that, the peripheral cards made a big difference too! I added a VIA 1394 card, an NEC USB2.0 card, and a SiS combo USB2.0 and 1394a card. The NEC seemed much more snappy at USB2.0! I also accidentally disabled the system once by plugging the irDA to the i2c SMbus header below it by mistake. So it has i2c support! I may try to learn how to use it and make a PWM fan controller for it! It would be sick to have something read the core temps and apply the PWM slopes for all the fans accordingly.

IF I can do that, i’ll definitely swap CPU fans! I heard some socket 775 coolers can be adapted to fit! I’d love to know if anyone has experience with adapting the two. If all fails, I have a drill press and a smart g/f…. Maybe I’ll post any updates

should I burden this beast with Vista to run DX10??

Some of these go beyond being annoying and straight to insidious because USB 2.0 and Ethernet are not obsolete.

People still use 2.0 for basic Flash storage. My 3D printer literally works by reading USB2.0 storage devices, and it's only 2 years old. I can't use my laptop to design for 3D printing because it requires adapters.

THEN FOR THE ETHERNET PORT! Ethernet cables are faster and more stable than wi-fi, not to mention the range without signal degradation with Ethernet is 100 yards, whereas even a router that COULD reach that far would have signal degredation, even with clear line of sight, long before you reached that point! Same could be said of most wired vs wireless connections. Including headphones!

all said and done, that means they get to sell you back your ability to fully use the laptop in bits and pieces. All for a device that overheats faster because it being so thin means the fans suck, assuming they get proper ventilation in the first place

この外付けハードディスクを使ってみた感想ですが、容量が16TBもあるので、TV番組の録画やPCのデータ保存にかなり便利です。

USB3.0対応なので転送速度も速く、データのやり取りがスムーズでした。

サイズがコンパクト���据え置きタイプとしても邪魔にならず、デザインもシンプルでかっこいいのが嬉しいポイントです。

コスパも良く、大容量ながら手頃な価格なのは魅力的ですね。

バックアップ用途にも適していて、長期間安心して使えそうです。

USB2.0との比較で転送速度の違いを実感できるので、古いモデルからの買い替えにもおすすめです。
