The Samsung 990 PRO with Heatsink 4TB is Samsung’s top PCIe 4.0 NVMe SSD with a factory-fitted heatsink, which makes it a drop-in upgrade for the PS5 as well as desktop PCs. Samsung rates it at up to 7,450 MB/s sequential read and 6,900 MB/s write, with up to 1,600K random read and 1,550K random write IOPS. It combines a Samsung-designed controller, Samsung V-NAND TLC flash and a 4GB LPDDR4 cache, and it is rated for 2,400 TBW.
Samsung 990 PRO with Heatsink 4TB: Table of Contents
Made for PS5 storage upgrades
Sony asks for a PCIe Gen4 M.2 drive of at least 5,500 MB/s with a cooling structure for the PS5 expansion slot. The Samsung 990 PRO with Heatsink 4TB meets both: it reads at up to 7,450 MB/s, ships with its heatsink already fitted, and Samsung lists it as PS5 compatible. At 80.15 x 25 x 8.88 mm it fits the console slot, and 4TB holds a large library of PS5 games without constant deleting.
DRAM cache and in-house controller
Unlike budget drives that borrow system memory, the 990 PRO has a dedicated 4GB LPDDR4 cache and a Samsung-designed controller. That keeps random performance high under mixed workloads, from large game installs to 4K and 8K video editing. Its 2,400 TBW rating is the highest of any 990 PRO capacity, and MTBF is rated at 1.5 million hours.
Heatsink with RGB lighting
The heatsink spreads heat so the drive holds its speed during long transfers, and an RGB light strip can be customised or switched off in Samsung Magician. Samsung says the 990 PRO with Heatsink delivers over 50% better performance per watt than the 980 PRO. Average power is 6.5 W when reading and 5.7 W when writing, with 55 mW at idle.
Samsung Magician and security
Samsung Magician software checks drive health, updates firmware and benchmarks performance on Windows. The Samsung 990 PRO with Heatsink 4TB also supports AES-256 hardware encryption and TCG Opal 2.0, useful for work desktops that store sensitive files.
Who This Is Not For
The heatsink raises the height to 8.88 mm, so the Samsung 990 PRO with Heatsink 4TB does not fit most laptops or handheld PCs; the version without a heatsink is the one for those. It is a PCIe 4.0 drive, so on a PCIe 5.0 motherboard it runs at Gen4 speed. If you only need a boot drive for office work, a 1TB or 2TB drive costs far less, and older PCs with only SATA ports cannot use M.2 NVMe drives.
