This category contains 2.5-inch SATA SSDs for upgrading laptops and desktop PCs, along with drives made for servers and workstations. Leading brands in our range include HP Enterprise, Transcend, ADATA, SanDisk and Dell. Capacities in our range start at around 240 GB and go up to 2 TB.
How to choose a SATA SSD
Capacity. Pick the size based on what you will store, not just the lowest cost per gigabyte. Our range includes 240 GB, 256 GB, 480 GB, 512 GB, 1 TB and 2 TB drives. 240 GB to 256 GB is enough for Windows and a few programs, while 480 GB to 1 TB suits a main drive that also holds games and files.
Intended use. Check whether the drive is made for consumer PCs or for servers. Some listings are marked for PC or laptop use, others for server or workstation use. Server drives are often tied to a specific vendor's systems, so confirm the model or part number against your hardware before you order.
Speed. The SATA III interface limits speed to roughly 550 MB/s, so most drives here quote sequential reads between 500 and 560 MB/s. Write speeds in our range commonly fall between 400 and 530 MB/s. Differences between drives are small in everyday use, and any of them is a large step up from a mechanical hard drive.
Durability. MTBF (mean time between failures) and the operating temperature range help you compare drives built for heavier workloads. Values in our range run from 1,000,000 to 2,000,000 hours. Many drives are rated for 0 to 70 °C, which matters if the drive sits in a warm server or a poorly ventilated case.
Interface and fit. Nearly all drives here use Serial ATA III, and they are backwards compatible with older SATA ports at reduced speed. The 2.5-inch format fits laptop bays directly. In a desktop you may need a mounting bracket and a SATA data cable, plus a SATA power connector from the power supply.
SATA SSD brands we carry
- HP Enterprise: makes drives for its ProLiant servers and storage systems, so they suit businesses replacing or expanding server storage.
- Transcend: a Taiwanese memory and storage maker, known for flash storage that spans consumer and industrial products.
- ADATA: a Taiwanese manufacturer offering SATA SSDs in a range of capacities for everyday PC upgrades.
- SanDisk: best known for flash memory cards and USB drives, and also sells SSDs aimed at upgrading older laptops and desktops.
- Dell: supplies drives intended for its own PowerEdge servers and workstations.
- Samsung: produces its own flash memory and controllers, which is why its SATA SSDs are a common benchmark for consumer drives.
Also in our range: Silicon Power, Patriot Memory, Intenso, Western Digital, Lexar and AFOX.
SATA SSD FAQ
Is a 2.5-inch SATA SSD worth it over a hard drive?
Yes, for most users the difference is clear. A SATA SSD has no moving parts, so Windows starts faster, programs open sooner and the system feels more responsive. It is also quieter and handles knocks better, which helps in laptops.
Can I use a 2.5-inch SATA SSD in a desktop PC?
Yes, a desktop can use one as long as it has a free SATA port and a SATA power connector. Many cases have dedicated 2.5-inch mounts. If yours only has 3.5-inch bays, a simple adapter bracket will hold the drive in place.
What is the difference between SATA and NVMe SSDs?
NVMe SSDs connect through PCIe and can be several times faster than SATA, which tops out at around 550 MB/s. SATA SSDs are still a sensible choice for older machines without an M.2 slot, or as a second drive. They are also easier to fit in laptops that were built around 2.5-inch drives.
Can I put a SATA SSD in a server?
Yes, if the server has a compatible 2.5-inch SATA bay, but check the manufacturer's supported parts first. Some servers need drives with a specific caddy or firmware, and enterprise drives are usually rated for heavier, continuous workloads than consumer models. Matching the part number to your server model avoids compatibility problems.
