Expert Shopping Tips for SSDs

Make sure to consider these factors when searching for a new SSD:

Storage Capacity: SSDs have matured in this regard, but extra space often comes at a cost. In most cases, 2 TB and 4 TB models are the best blend of ample storage space and affordable prices. Regardless, a 1 TB SSD may suit someone simply looking for a better system drive. Or a power user might prefer an 8 TB SSD. Account for your current capacity and future growth.

Form Factor: Modern SSDs are available in several shapes and sizes. Most of the attention centers on M.2 SSDs, but slots for these compact drives are limited in many computers. Other types of SSDs exist, though. Some video game consoles, such as the Xbox Series X|S or handheld PCs, require different form factors. Even a 2.5-inch SSD has a role in specific machines.

Interface: In general, Non-Volatile Memory Express (NVMe) is the ideal interface for SSDs. The protocol defines how the drive’s firmware exchanges commands with the host system’s motherboard. While NVMe is the fastest interface for consumers, SATA SSDs still offer improved throughput over hard disks.

Bus Type: Peripheral Component Interconnect Express (PCIe) is the most popular standard for SSDs. PCIe refers to high-speed lanes that shuttle data between the SSD, central processor, random-access memory (RAM), and graphics card. This physical connection impacts the device’s transfer rates. Not all motherboards support the latest generation of PCIe. Therefore, a Gen 5 SSD will bottleneck compared to an older PCIe spec. Review your motherboard's manual for more info.

Cell Type: SSDs store a varying amount of bits per cell. Single-level cell (SLC) provides the highest throughput and lowest density. It also wears out the fastest. Multi-level cell (MLC) and triple-level cell (TLC) designs aim to strike a balance between capacity and performance. Quad-level cell (QLC) provides the most storage space but heavily relies on caching to compensate for slower speeds. However, a cache of faster memory can quickly fill up and prevent the controller from flushing data back to the main cells. This saturation throttles the drive.

Specialized Features: Manufacturers tailor some SSDs to address specific workflows or failure modes. Advanced features include DRAM (dynamic RAM) or SLC caching, power-loss protection, and thermal management.

Warranty: SSDs are complex devices. A robust warranty can guard against financial loss due to a catastrophic failure of your drive. Established companies typically extend the strongest terms to their customers.

Being mindful of these attributes will help you make the perfect purchase.

Some laptops do not have an M.2 slot. If that is the case, replacing the old drive with a new SATA SSD might work. As stated above, the Samsung 870 EVO is a popular SATA SSD due to its proven performance and fair price tag. Check the type of SSD your laptop supports before buying a new device.

Best SSD for NAS Devices

Deploying SSDs in NAS is a very niche case. The majority of home users and small businesses will not derive significant benefits from an all-flash NAS unit. Especially given the increased cost of enterprise SSDs.

If you plan to outfit your homelab or office NAS with SSDs:

  • Confirm the drive bays, slots, and backplanes inside the NAS appliance. This step will determine your SSD’s form factor, interface, and bus type.
  • Look for models with better write endurance. Metrics such as TBW (terabytes written) and DWPD (drive writes per day) give key insights into endurance.
  • Opt for MLC (multi-level cell) or TLC (triple-level cell) over QLC (quad-level cell) despite the higher cost per TB. As mentioned, QLC suffers from lower endurance and slower performance under sustained workloads.
  • Consider features like firmware fine-tuned for RAID with power-loss protection.

Note: Striping data across a pair of SSDs through RAID 0 is possible. This setup would improve throughput on a benchmark, but the real-world performance of a single SSD is almost identical. In addition, installing a high-end SSD is not as complex and carries less risk.
