🔹 1. What are SSDs and why are they so important?
Solid State Drives (SSDs) are the new generation of storage devices that have almost completely replaced the old mechanical disks. Unlike traditional disks that use rotating parts (like small CDs that spin at thousands of revolutions per minute), SSDs store data in special memory that has no moving parts. Think of it like the difference between an old cassette player and a modern memory card in your phone.
🎯 Why are SSDs better than old drives?
⚡ Speed: Load programs and files 10-50 times faster - the computer starts up in seconds instead of minutes
(I.e. Silence: They don't make noise because they have no moving parts - you won't hear the characteristic "creaking" sound anymore
🛡️ Stamina: They are more resistant to shocks and vibrations - ideal for laptops
(I.e. Energy saving: They consume less power, so more autonomy for laptops
🌡️ Temperature: They stay cooler during operation, they don't heat up the machine as much
Upgrading to an SSD is the most effective change you can make to your computer - even on an old machine, the difference is noticeable from the very first moment. The operating system wakes up faster, programs open almost instantly, and the overall user experience becomes much smoother.
🔹 2. SATA SSD: The Economical and Reliable Choice
SATA SSDs are the most affordable category of SSDs and are a great option for those looking to upgrade an older computer without spending a lot of money. They use the same connection as older mechanical drives, so they are compatible with almost all computers - even those built 10-15 years ago.
📊 Key Features of SATA SSD
🏃♂️ Speed: Approximately 550 MB/s - transfer an HD movie within 10 seconds
(I.e. Connection: SATA cable (like old drives) - easy replacement without special knowledge
💰 Price: From €30-80 for 500GB - the most economical solution for an immediate upgrade
(I.e. Size: 2.5 inches (like a small notebook or old smartphone)
🎯 Ideal for: Daily use, internet browsing, documents, music, basic programs
✅ Advantages
✔️ Very economical in relation to the performance they offer
✔️ Compatible with all computers, old and new
✔️ Easy installation - just disconnect the old one and connect the new one
✔️ Reliable and durable for basic uses
✔️ Available in large capacities at affordable prices
❌ Disadvantages
❌ Limited speed compared to newer solutions - but still much better than old disks
❌ Two cables are needed (one for data, one for power)
❌ Larger size than M.2 - takes up space in the box
Practical Advice: If your computer still has an old mechanical drive, upgrading to a SATA SSD will be the most impressive change you've ever made. It'll feel like you bought a new computer! A SATA SSD is the smartest investment for old machines.
🔹 3. NVMe SSD: Speed for Gaming and Productivity
NVMe SSDs represent modern storage technology and offer impressive speeds that make a difference in demanding applications. They are ideal for gamers, content creators and anyone who wants the best possible performance from their computer. NVMe is not a type of drive but a way of communicating - think of it as a highway instead of the one-way street that SATA drives use.
📊 Key Features of NVMe SSD
🚀 Speed: 3.000 - 7.000MB/s - that is 5-12 times faster than SATA!
(I.e. Connection: M.2 port (small slot on the motherboard) - without any cables
💰 Price: From €50-150 for 500GB - the price difference with SATA has narrowed significantly in 2025
(I.e. Size: Very small (like a piece of gum or AA battery) - almost invisible inside
🎯 Ideal for: Gaming, video and photo editing, programming, opening multiple programs at once
💡 Practical Example: A game like Cyberpunk 2077 that takes 1-2 minutes to load with a SATA SSD, with NVMe will load in 15-30 seconds! Also, transitioning between levels or areas is almost instantaneous.
✅ Advantages
✔️ Excellent speeds that improve all applications
✔️ Very small size, no cables needed at all
✔️ Ideal for laptops due to size and consumption
✔️ Significantly improve the gaming experience - less waiting, more gaming
✔️ Modern games are optimized for them
✔️ Better response to programs with large files
❌ Disadvantages
❌ More expensive than SATA, although the difference is decreasing
❌ Requires a motherboard with an M.2 port (most after 2018 have it)
❌ Can get hot under heavy use - sometimes requires a heatsink
❌ Some old computers cannot boot from them
Caution: There are different generations of NVMe (PCIe 3.0, 4.0, 5.0). For most users, an NVMe PCIe 3.0 or 4.0 is more than enough - the differences in everyday use are minimal. Don't spend extra on PCIe 5.0 unless you have very specific business needs.
🔹 4. PCIe SSD: The Ultimate Performance for Professionals
PCIe SSDs are the pinnacle of storage technology and offer the fastest speeds available today. Important note: All NVMe drives use a PCIe connection, but when we talk about "PCIe SSDs" we usually mean drives that are installed directly into an expansion slot (like a graphics card), not an M.2 slot. These are mainly aimed at professionals who work with huge files or servers that serve many users at once.
📊 Key Features of PCIe SSD (Add-in Card)
⚡ Speed: 7.000 - 14.000 MB/s and above - almost as fast as RAM reads
(I.e. Connection: Directly to PCIe port on motherboard (like a graphics card)
💰 Price: From 200-600€ for 500GB - for professional use
(I.e. Size: Expansion card (like a smaller graphics card)
🎯 Ideal for: Professional video studios, scientific data analysis, servers, specialized applications
🎯 When is a PCIe SSD with an expansion card worth it: Only if you work professionally with huge 4K/8K videos on a daily basis, analyze huge databases, or manage a server that has to serve many users simultaneously. For 99% of users, even gamers and content creators, a good NVMe is more than enough.
Important Note: Most users who think they need a PCIe SSD actually just want a fast NVMe. The price difference is huge and the improvement in everyday use is minimal. Even for 4K video editing, a good NVMe PCIe 4.0 is excellent.

💡 Golden Tip for 2025: NVMe prices have dropped so much that for a new system it's no longer worth getting SATA. The difference is only 10-20€ and you get 5-10 times more speed. SATA remains ideal only for upgrading old computers that don't have an M.2 port.
🔹 6. Market Tips
Choosing the right SSD isn't as difficult as it seems. The key is to understand what you really need and not pay for features you won't use. The average user won't see a difference between a 3.500 MB/s NVMe and a 7.000 MB/s one in everyday use - the difference is only noticeable in very specific applications.
💡 Before you buy, check the following:
🔍 Check compatibility: Before you buy, make sure your motherboard supports the type of SSD you want. For M.2 NVMe, check the manual or manufacturer's website.
(I.e. You adjust the capacity: 500GB is the absolute minimum for modern use (functional + a few games), 1TB is more comfortable and usually has a better price-capacity ratio. For gamers who download a lot of games, think 2TB.
🏷️ You choose reliable brands: Samsung, Crucial, Western Digital (WD), Kingston, SK Hynix are safe choices with a good warranty. Avoid unknown Chinese brands, even if they are cheap.
⚡ Don't overdo it: A SATA SSD is already a huge upgrade from an old mechanical drive - you don't need to get the most expensive one to see a difference.
🌡️ Beware of heat: If you get fast NVMe (over 5.000 MB/s), consider getting a small heatsink - it costs €5-10 and keeps the drive cool.
📦 Warranty and TBW: Look at the warranty (usually 3-5 years) and TBW (Total Bytes Written - how much data it can write in its lifetime). For the average user, even the most basic SSD will last 10+ years.
💰 Beware of offers: SSD prices fluctuate. If you're not in a hurry, keep an eye on prices for 1-2 weeks - there are often 20-30% discounts.
🎮 For PS5/Xbox: If you're looking for a console, you need a specific NVMe with a minimum speed of 5.500 MB/s for PS5. Read the specifications before buying.
🎯 Specific Suggestions per Category (2025):
For Economic Upgrade (30-60€):
Look for SATA SSDs from Crucial BX500, WD Green, or Kingston A400. They all do an excellent job for basic use.
For Gaming (60-120€):
Look for NVMe PCIe 3.0 or 4.0 with at least 3.000 MB/s. The Crucial P3, WD Blue SN580, or Samsung 980 are great options at a good price.
For Professional Use (150-300€):
Choose NVMe PCIe 4.0 with high speeds and good endurance. The Samsung 990 PRO, WD Black SN850X, or Crucial T700 are top choices.
🚫 What to AVOID:
❌ Unknown brands: Don't be tempted by overly cheap discs from unknown companies - reliability is more important than a €10 savings
❌ Used SSDs: You don't know how much they've been used - better new with a warranty
❌ Very small capacity: A 128GB or 256GB drive will fill up instantly - it's a pseudo-economy
❌ Too fast for basic use: If you're just surfing the internet, you don't need 7.000 MB/s NVMe
❌ DRAM-less drives for systems: If it's for an operating system, prefer a drive with DRAM cache (most drives over €50 have it)
🎉 To summarize: NVMe SSDs offer the best speed-to-price ratio for most users and are the recommended choice for new systems. If you're on a budget or have an older computer without an M.2 port, a SATA SSD will be more than enough and will be like getting a new machine. If you're a professional with very specific needs for processing huge files, then it's worth investing in a top-of-the-line NVMe PCIe 4.0 or 5.0 - separate PCIe cards are now for very specialized applications.
Any upgrade to an SSD is a huge step forward. Don't worry too much about which type is "perfect" - all modern SSDs are excellent compared to old mechanical drives. Choose one that fits your budget and usage, and enjoy the speed!
