What to Look for When Buying Buying Guide
1. Interface Type: SATA vs. NVMe
The interface your SSD uses determines how fast data can travel between the drive and your system. Samsung offers two primary types: SATA III and NVMe (Non-Volatile Memory Express). SATA III drives, like the Samsung 870 QVO, connect via the traditional SATA port and max out at around 560 MB/s read/write speeds. While this is significantly faster than older HDDs, it’s considered entry-level by today’s standards. NVMe drives, such as the Samsung 990 PRO or 980, use the PCIe interface and connect directly to the motherboard via an M.2 slot. These drives can deliver speeds exceeding 7,000 MB/s—over 10 times faster than SATA. If your system supports NVMe (most modern desktops and laptops do), it’s almost always worth the upgrade. However, if you’re working with an older machine that only has SATA ports, a high-quality SATA SSD like the 870 EVO is still a fantastic choice.
2. Form Factor: M.2 vs. 2.5-inch
Samsung SSDs come in two main physical forms: the compact M.2 stick and the traditional 2.5-inch drive. M.2 drives are tiny, rectangular modules that plug directly into your motherboard—no cables required. They’re ideal for slim laptops, small-form-factor PCs, or anyone who values a clean build. The 2.5-inch form factor, used in drives like the 870 EVO, resembles a small laptop hard drive and connects via SATA cables. While slightly bulkier, these are easier to install in older systems and often more budget-friendly. When choosing, check your device’s specifications: many modern laptops only support M.2, while desktops may offer both options. Always verify the M.2 key type (usually M-key for NVMe) and length (commonly 2280, meaning 22mm wide and 80mm long).
3. Performance Specifications: Read/Write Speeds and IOPS
Raw speed numbers matter—but context matters more. Samsung publishes sequential read/write speeds (e.g., 7,450 MB/s read for the 990 PRO), which reflect how quickly large files like videos or game installs transfer. However, real-world performance also depends on random read/write speeds, measured in IOPS (Input/Output Operations Per Second). High IOPS mean better responsiveness when multitasking or loading many small files, such as during OS boot or application launches. For example, the Samsung 980 PRO delivers up to 1,400K IOPS, making it excellent for gaming and content creation. Casual users may not notice the difference between 500K and 1M+ IOPS, but professionals working with 4K video or large databases will appreciate the boost. Always look at both sequential and random performance metrics when comparing models.
4. NAND Flash Technology: TLC vs. QLC
Samsung uses different types of NAND memory in its SSDs: Triple-Level Cell (TLC) and Quad-Level Cell (QLC). TLC stores three bits per cell and offers a great balance of speed, endurance, and cost—it’s used in premium drives like the 990 PRO and 870 EVO. QLC stores four bits per cell, increasing storage density and lowering price per gigabyte, but at the expense of write speed and longevity. The Samsung 870 QVO, for instance, uses QLC and is best suited for read-heavy tasks like media storage or backups. While QLC has improved significantly in recent years, TLC remains the gold standard for performance and durability. If you plan to frequently write large amounts of data (e.g., video editing, game development), stick with TLC-based drives.
5. Endurance and TBW Rating
SSD lifespan is measured in Terabytes Written (TBW)—the total amount of data that can be written to the drive before it may start to fail. Samsung provides TBW ratings for all its drives, and they’re a reliable indicator of longevity. For example, the 1TB Samsung 990 PRO has a TBW rating of 600TB, while the 870 EVO offers 600TB as well. The more modest 870 QVO comes in at 360TB. To put this in perspective, if you write 50GB of data daily, a 600TB drive would last over 32 years. Even heavy users are unlikely to hit these limits, but higher TBW provides peace of mind, especially for workstations or servers. Always check the TBW rating, particularly if you’re using the SSD for intensive workloads.
6. DRAM Cache: Why It Matters
A DRAM cache acts as a high-speed buffer between the SSD controller and NAND memory, significantly improving performance and longevity. Samsung’s high-end NVMe drives, like the 990 PRO and 980 PRO, include a dedicated DRAM chip. This allows for faster mapping of data locations and better handling of sustained workloads. Drives without DRAM (sometimes called DRAM-less), such as the budget-friendly Samsung 980 (non-PRO), rely on system memory (HMB—Host Memory Buffer) instead. While HMB works well for light tasks, it can lead to performance drops under heavy load. If you’re doing anything beyond basic file storage or web browsing, a DRAM-equipped SSD is strongly recommended.
7. Encryption and Security Features
Data security is increasingly important, and Samsung integrates robust encryption into its SSDs. Most Samsung drives support AES 256-bit hardware encryption and are compliant with TCG Opal and IEEE 1667 standards. This means you can enable password protection and full-disk encryption without taxing your CPU. Some models, like the Samsung T7 Shield portable SSD, also include built-in password protection via Samsung’s Magician software. If you’re storing sensitive work files, personal documents, or financial data, look for drives with strong encryption support. It’s a small feature that can prevent major headaches down the line.
8. Warranty and Support
Samsung backs its SSDs with some of the best warranties in the industry—typically 5 years or up to the TBW limit, whichever comes first. This reflects confidence in their build quality and longevity. Additionally, Samsung provides free firmware updates, diagnostic tools, and cloning software through its Samsung Magician application. The software lets you monitor drive health, optimize performance, and securely erase data. When comparing brands, Samsung’s support ecosystem is a significant advantage. Always register your drive online to ensure full warranty coverage and access to updates.
Different Types of Buying Guide
Common Buying Mistakes to Avoid
❌ Mistake: Ignoring Your System’s Compatibility
Why it’s bad: Buying a PCIe 4.0 NVMe drive for a laptop that only supports SATA will result in a useless brick. Many users assume all M.2 slots support NVMe, but some older systems only accept SATA-based M.2 drives.
What to do instead: Always check your motherboard or laptop manual for supported interfaces and form factors. Use tools like CPU-Z or Samsung’s compatibility checker before purchasing.
❌ Mistake: Choosing QLC Over TLC for Heavy Workloads
Why it’s bad: QLC drives like the 870 QVO slow down significantly during sustained writes because they lack a large SLC cache. This can cripple performance during video renders or large file transfers.
What to do instead: Reserve QLC for archival storage or light use. For active projects, gaming, or OS drives, always opt for TLC-based models like the 980 PRO or 870 EVO.
❌ Mistake: Overlooking the Importance of DRAM
Why it’s bad: DRAM-less SSDs may seem like a bargain, but they can suffer from inconsistent performance, especially when the drive is nearly full or under heavy multitasking.
What to do instead: Unless you’re on an extremely tight budget, prioritize drives with onboard DRAM. The performance and longevity benefits far outweigh the small price difference.
❌ Mistake: Skipping Firmware Updates
Why it’s bad: Outdated firmware can lead to bugs, reduced performance, or even data corruption. Samsung regularly releases updates to improve stability and security.
What to do instead: Install Samsung Magician software and enable automatic update notifications. Check for updates every few months.
❌ Mistake: Buying Based Solely on Price
Why it’s bad: The cheapest SSD isn’t always the best value. A low-cost drive with poor endurance or no encryption could cost you more in the long run due to failures or data loss.
What to do instead: Consider total cost of ownership—including warranty, performance, and features—not just the upfront price.
❌ Mistake: Not Backing Up Before Cloning
Why it’s bad: Cloning your old drive to a new SSD without a backup risks losing everything if the process fails or the source drive is corrupted.
What to do instead: Always create a full system image backup before cloning. Use Samsung’s Data Migration tool alongside a third-party backup solution for safety.
❌ Mistake: Assuming All 1TB Drives Are Equal
Why it’s bad: Two 1TB SSDs from the same brand can perform dramatically differently based on interface, NAND type, and controller. A SATA 870 EVO and an NVMe 990 PRO are worlds apart.
What to do instead: Compare specs side-by-side. Look beyond capacity and focus on real-world performance metrics and use case alignment.
Budget Guidelines: How Much Should You Spend?
Entry-Level ($60–$80): At this price point, you’ll find DRAM-less NVMe drives like the Samsung 980 (non-PRO) or older SATA models such as the 860 EVO. These are suitable for basic computing, web browsing, and light office work. Expect decent speeds for everyday tasks but reduced performance under load. Ideal for secondary storage or upgrading an old laptop on a tight budget.
Mid-Range ($80–$120): This is the sweet spot for most users. Drives like the Samsung 980 PRO (PCIe 3.0) or 870 EVO offer excellent performance, full DRAM caches, and strong endurance.
