Frequently asked questions
What is a good price per TB for an SSD in 2026?
In 2026, a good price per terabyte for a SATA SSD is around £50-70/TB. High-capacity drives (2TB+) offer better value, sometimes dropping to £40-50/TB during sales. While SSDs cost more than HDDs, prices have fallen significantly, making them affordable for most users.
How much does an SSD cost?
SSD prices vary by capacity: a 256GB SATA SSD costs £15-25, a 512GB costs £25-40, a 1TB costs £40-70, and a 2TB costs £80-140. Prices depend on the brand and performance tier. Use our comparison table above to see today's best UK prices.
What's the difference between SATA SSD and NVMe SSD?
SATA SSDs connect via the SATA interface (same as HDDs) with speeds up to 550MB/s. NVMe SSDs use the faster PCIe interface, achieving speeds of 3,500-7,000MB/s. For general use, SATA SSDs are fine; for gaming, video editing, or professional work, NVMe offers significant benefits.
How long do SSDs last?
Modern SSDs are rated for 150-600 TBW (terabytes written), meaning you could write 150-600TB before wear becomes a concern. For typical consumer use (50GB/day), this translates to 8-30+ years. SSDs generally outlast the systems they're installed in.
Should I buy a 2.5-inch or M.2 SSD?
2.5-inch SATA SSDs are compatible with any system that has SATA ports and are easy to install. M.2 SSDs are smaller and plug directly into the motherboard, but come in both SATA and NVMe variants. Check your motherboard compatibility before buying an M.2 drive.
What is the cheapest SSD per terabyte?
The cheapest SSDs per terabyte are typically high-capacity 2TB-4TB SATA models from brands like Crucial, Kingston, and Samsung. Prices can dip below £40/TB for budget models. Check our table above sorted by price per TB to find the current best deals.
Is a SATA SSD still worth buying in 2026?
Yes, SATA SSDs are still a great buy in 2026, especially if your PC lacks an M.2 NVMe slot or you want the cheapest SSD option. The difference between SATA and NVMe in everyday tasks (web browsing, documents, general use) is barely noticeable. SATA SSDs are still dramatically faster than hard drives.
