4TB SATA III 2.5"Read 560 Write 520Western Digital
The WD Blue SA510 4TB is a 2.5-inch internal SATA SSD designed for compatible desktops and laptops that use a standard SATA drive bay. Model WDS400T3B0A uses a 7 mm cased form factor and the SATA III 6 Gb/s interface, with backward compatibility to earlier SATA generations. The 4TB model is rated for sequential reads up to 560 MB/s and sequential writes up to 520 MB/s, providing a practical upgrade for faster booting, application loading, editing and file transfers compared with a mechanical hard drive.Random performance is specified at up to 87k read IOPS and 83k write IOPS, while endurance is rated at 600TB TBW. Western Digital specifies up to 2.25 million hours MTTF and a five-year limited warranty, giving this high-capacity model a strong durability profile for sustained everyday workloads. The drive is also designed with low active power draw, helping it suit systems where efficiency and reduced vibration are useful.Acronis True Image for Western Digital supports cloning and backup when moving data to the SSD, while Western Digital SSD Dashboard can monitor drive health, temperature, available space and firmware. Installation requires a compatible 2.5-inch SATA connection and a bay that accepts a 7 mm drive; compatibility depends on the host system specification.

500GB SATA III 2.5"Read 550 Write 500Crucial
The Crucial BX500 500GB is a 2.5-inch internal SATA SSD for compatible laptops and desktop PCs, using the SATA III 6 Gb/s interface in a 7 mm drive format. Model CT500BX500SSD1 combines 500GB of solid-state storage with sequential read speeds up to 550 MB/s and sequential write speeds up to 500 MB/s, making it a straightforward replacement for a slower mechanical hard drive where faster start-up, file access and application response are required.Crucial specifies Micron 3D NAND together with SLC write acceleration, thermal monitoring, TRIM support, SMART monitoring, active garbage collection, error correction code and a multistep data integrity algorithm. The 500GB version is rated for 120TB total bytes written and a 1.5 million-hour MTTF. These features focus on stable everyday SATA performance rather than adding unnecessary interface claims beyond the limits of SATA 6 Gb/s.Acronis True Image for Crucial cloning software is provided for data migration, and Crucial Storage Executive supports drive management and firmware updates. The drive is covered by a three-year limited warranty or the published TBW limit, whichever comes first. Installation requires a compatible 2.5-inch SATA bay and SATA connection, with final compatibility determined by the host system. Brand Crucial Model CT500BX500SSD1 Capacity 500GB Drive Type Internal SATA SSD Form Factor 2.5-inch SATA Interface SATA III 6 Gb/s SATA Revision SATA III Drive Thickness 7 mm Max Sequential Read Speed Up to 550 MB/s Max Sequential Write Speed Up to 500 MB/s NAND Type Micron 3D NAND Endurance / TBW 120TB TBW

2TB SATA III 2.5"Read 560 Write 530Samsung
The Samsung 860 PRO 2TB is a 2.5-inch internal SATA SSD built for demanding client systems that require sustained SATA performance and high write endurance. Model MZ-76P2T0B/EU uses Samsung V-NAND 2bit MLC, the Samsung MJX controller and 2 GB of LPDDR4 DRAM cache. It connects through SATA 6 Gb/s and is backward-compatible with SATA 3 Gb/s and 1.5 Gb/s interfaces, while the 6.8 mm case suits compatible 2.5-inch drive bays.Sequential performance is rated up to 560 MB/s read and 530 MB/s write. At 4 KB QD32, Samsung specifies up to 100,000 random read IOPS and 90,000 random write IOPS, with QD1 figures of up to 11,000 read and 43,000 write IOPS. The 2TB model carries a 2,400TB TBW endurance rating and a five-year limited warranty, making it particularly suited to heavier write workloads within the limits of the SATA interface.Security features include AES 256-bit hardware full-disk encryption, TCG Opal 2.0 and IEEE1667 encrypted-drive support. Samsung Magician provides firmware, health and performance management. The 860 PRO is positioned for high-end PCs, workstations and compatible NAS use; installation still requires a suitable 2.5-inch SATA connection and host-system support.

4TB NVMe M.2 2280Read 14800 Write 13400Samsung
The Samsung 9100 PRO 4TB is an internal M.2 2280 NVMe SSD using a PCIe 5.0 x4 interface. This exact product is identified by manufacturer part number MZ-VAP4T0BW; the capacity, interface and thermal configuration in this listing apply to that SKU rather than to another version in the same series.Manufacturer-rated performance reaches up to 14800 MB/s sequential read and 13400 MB/s sequential write, providing high sequential bandwidth for application loading, large file transfers, content work and other storage-heavy tasks. This SKU is supplied without an integrated heatsink, so the host system's own cooling arrangement and available M.2 clearance should be considered. Installation requires a system that physically accepts M.2 2280 storage and supports NVMe over the stated PCIe interface.Form factor, PCIe generation and NVMe protocol are separate requirements, so one of those specifications must not be used as proof of the others. Actual throughput can be below the quoted maximum because it depends on the host controller, available PCIe bandwidth, firmware, workload, queue depth and thermal conditions. The confirmed protocol version for this model is NVMe 2.0.
