pt	Hardware recomendado

en	Laptop models evolve too rapidly for us to be able to provide an up-to-date list of recommended hardware. Below are some guidelines if you, or your organization, are considering acquiring a laptop dedicated to running Tails.
pt	Os modelos de laptop evoluem rápido demais para que possamos manter uma lista atualizada de hardware recomendado. Abaixo estão algumas orientações caso você ou sua organização estejam condierando adquirir um laptop dedicado a rodar o Tails.

en	For PC
pt	Para PC

en	Avoid "gaming" models with Nvidia or AMD Radeon graphics cards.
pt	Evite modelos "gamer" com placas de vídeo Nvidia ou AMD Radeon.

en	Consider buying a refurbished laptop from a high-end (professional) series. These are cheaper and will last longer than new but lower-quality laptops.
pt	Considere a possibilidade de comprar um laptop recondicionado de alguma série (profissional) topo de linha. Eles são baratos e vão durar mais do que se você comprar laptopos novos mas de baixa qualidade.

en	For example, the Lenovo ThinkPad series work well with Tails, including the X250, X1 Carbon, T440, T480, and T490 models.
pt	Por exemplo, a série Lenovo ThinkPad funciona bem com Tails, incluindo os modelos X250, X1 Carbon, T440, T480 e T490.

en	If you live in a part of the world where buying refurbished laptops is uncommon, look on eBay and Amazon. Amazon offers a 90-day [Amazon Renewed Guarantee](https://www.amazon.com/gp/help/customer/display.html?nodeId=G4ZAA22U35N373NX).
pt	Se você vive em uma pate do mundo onde comprar laptops recondicionados não é comum, dê uma olhada no eBay e Amazon. A Amazon oferece a [Garantia Renovada Amazon](https://www.amazon.com/gp/help/customer/display.html?nodeId=G4ZAA22U35N373NX) de 90 dias.

en	Consider buying a new laptop from vendors who guarantee the compatibility with Linux and Tails like [ThinkPenguin](https://www.thinkpenguin.com/).
pt	Considere a possibilidade de comprar um laptop novo de fornecedores que garantam a compatibilidade com Linux e Tails, tais como [ThinkPenguin](https://www.thinkpenguin.com/).

en	For Mac
pt	Para Mac

en	Tails still works on some older Mac computers with an Intel processor.
pt	Tails funciona em alguns computadores Mac antigos que possuem processador Intel.

en	Unfortunately, we don't know of any Mac model that works well in Tails and can run the latest macOS version.
pt	Infelizmente, nós não sabemos de nenhum modelo de Mac que funciona bem com Tails e consegue rodar a versão mais recente do macOS.

en	<!--

en	To update the list of Mac computer:

en	Store an archive of WhisperBack reports from the last 6 months in a folder.

en	Decrypt all the reports:

en	~/Tails/blueprints/stats/whisperback_scripts/decrypt.rb

en	Extract the list of computer models:

en	~/Tails/blueprints/stats/whisperback_scripts/content_of.rb "/usr/sbin/dmidecode -s system-product-name" > machines

en	Sort and count identical models:

en	grep -v Bug_report machines | sort | uniq -c | sort -rhk 1 > top

en	Share WhisperBack reports number with the Tails team and ask them to evaluate hardware compatibility hints in those reports.

en	While analyzing the reports corresponding from each model, FT should:

en	Check whether they were sent from the same email address, if any

en	Check whether the wlan0 interface was the same hardware device

en	Check whether the report was about hardware compatibility issues

en	Check whether these Mac models still support the latest version of macOS.

en	To update the list of PC computers:

en	Check what's commonly available with refurbishing companies.

en	Ask assembly@ for models.

en	Recommended USB sticks

en	You need a USB stick of 8 GB minimum to use Tails.
pt	- Um pendrive USB de no mínimo 8 GB ou um DVD gravável.

en	All the data on this USB stick is lost when installing Tails.
pt	Todos os dados no pendrive USB ou no DVD são perdidos ao instalar Tails.

en	The quality of your USB stick is crucial when using Tails. A bad USB stick will be slower and more likely to corrupt the files in your [[Persistent Storage|doc/persistent_storage]].

en	We recommend that you:

en	**Buy new USB sticks.**

en	USB sticks become slower and less reliable over the years. Older USB sticks were also built with slower technology.

en	**Buy USB sticks from well-known brands, such as [[Kingston|https://www.kingston.com/en/usb-flash-drives]], [[Samsung|https://www.samsung.com/us/computing/memory-storage/usb-flash-drives/]], and [[SanDisk|https://www.sandisk.com/product-portfolio/usb-flash-drives]].**

en	Generic brands are more likely to be slower and less reliable.

en	Any modern USB stick from a well-known brand is fast enough to use Tails comfortably.

en	**Buy your USB sticks from a reputable local store.**

en	If you are in a place where counterfeit electronics are common, buy your USB stick from an international supermarket chain, which should have a more reliable supply chain.

en	Avoid buying USB sticks online or using USB sticks that were given to you, because they could contain malware.

en	<div class="attack">

en	In 2020, the [[FBI warned US companies to avoid USB sticks received by mail|https://www.cybereason.com/blog/fbi-warns-us-companies-to-avoid-malicious-usb-devices]] because some of them contained malicious software, such as [[!wikipedia BadUSB]].

en	</div>

en	**Consider buying faster USB sticks that support USB version 3.0 or later.**

en	Check the specifications of your computer to determine whether your USB ports support USB 3.0 or later. USB 3.0 ports are sometimes blue.

en	USB 3.0 can be up to 10 times faster than USB 2.0. USB 2.0 has a maximum read speed of around 50 MB/s on USB sticks, while USB 3.0 has a maximum read speed of around 500 MB/s.

en	Most quality USB sticks nowadays have read speeds of at least 100 MB/s and are faster when used on USB 3.0 ports. Some USB sticks advertised for USB 3.0 have even greater speeds.

en	You can test the write speed of your different USB sticks by comparing the time it takes to [[clone Tails|install/clone/pc]], for example.

en	How many USB sticks should I buy?

en	If you want to store personal files and configuration in an encrypted [[Persistent Storage|doc/persistent_storage]], we recommend that you buy 2 USB sticks, ideally 3:

en	1 USB stick to be your **primary Tails**.

en	1 USB stick of the same size to be your **backup Tails**, if you use the Persistent Storage.

en	We recommend that you [[create a backup Tails|doc/persistent_storage/backup]] by cloning your primary Tails, including its Persistent Storage.

en	1 USB stick to do [[manual upgrades|doc/upgrade]] on a few occasions when automatic upgrades are not available.

en	This USB stick can be of a smaller size and worse quality.
