This article covers SAMSUNG 990 EVO 1 TB hasta 5.000 MB.

Overview

The Samsung 990 EVO (model MZ-V9E1T0BW) is a 1TB NVMe M.2 SSD that supports both PCIe 4.0 x4 and PCIe 5.0 x2 interfaces. With sequential read speeds up to 5,000MB/s and write speeds up to 4,200MB/s, it delivers about 43% faster performance than the previous 970 EVO Plus. Samsung focused on power efficiency this time: the 990 EVO boasts up to 70% better energy efficiency compared to its predecessor, thanks to modern standby support and an optimized controller. The inclusion of a heat spreader label and Dynamic Thermal Guard helps maintain consistent performance under load without throttling. This drive is positioned as a mid-range all-rounder, suitable for everyday computing, gaming, and light creative work. The bundled Samsung Magician software makes firmware updates and drive health monitoring easy, even for less experienced users.

Compatibility Guide

The 990 EVO uses the standard M.2 2280 (Type 2280-D2) form factor with an NVMe interface. Physical dimensions are 22x80mm, meaning it fits into almost any desktop or laptop M.2 slot that supports NVMe. Its key compatibility feature is dual-mode PCIe: it works as a PCIe 4.0 x4 device in older platforms (e.g., Intel 12th/13th Gen, AMD AM4) and as a PCIe 5.0 x2 device in newer ones (Intel Z890, AMD X870E, etc.). Note that PCIe 5.0 x2 provides the same total bandwidth as PCIe 4.0 x4 (approx. 8 GT/s per lane), so there's no bandwidth penalty when using the 5.0 mode. The SSD uses Host Memory Buffer (HMB) instead of a dedicated DRAM cache. This is fine for general usage but may show slightly lower sustained write speeds under very heavy random workloads compared to DRAM-equipped drives.

Product Info

Launched in early 2024, the Samsung 990 EVO sits in the mid-range tier of Samsung's SSD lineup. The 1TB model currently retails for around ¥69,947 on Japan (as of June 2026). It carries a 5-year limited warranty and an endurance rating of 600 TBW (Total Bytes Written). The drive's sequential performance is well-suited for modern gaming and productivity apps. It lacks a dedicated DRAM cache but compensates with HMB, which uses a small portion of system RAM as a write cache. This keeps costs down while maintaining good everyday performance.

Best Use Cases

Gamers: With 5,000MB/s sequential reads, the 990 EVO can handle DirectStorage titles and speed up level loading. It's a great drop-in upgrade for a gaming desktop or laptop. However, if you plan to frequently install and run the latest AAA games that stream large textures, a PCIe 5.0 x4 drive like the 990 Pro might offer marginal benefits. Creative professionals: For 4K video editing, large photo libraries, and 3D asset loading, the write speed of 4,200MB/s is competitive. But for sustained heavy writes (e.g., continuous 4K/8K video recording or massive file transfers), a DRAM-based drive (990 Pro, SN850X) would be more consistent. Laptop users: The 70% improvement in power efficiency makes this an excellent choice for ultrabooks and gaming laptops. Low heat output also helps in thin chassis where cooling is limited. Secondary storage: The 990 EVO is an affordable upgrade for adding extra capacity. It's not overkill for a game library or media storage drive. For OS boot drives, it performs well, but some users may prefer a DRAM-enabled drive for heavy multitasking. ## Alternatives
Direct competitors include the Crucial P41 Plus (up to 4,125/3,300 MB/s, 500TBW) and WD_BLACK SN770 (up to 5,150/4,900 MB/s, 600TBW). Both are also DRAM-less HMB drives at similar price points. The 990 EVO distinguishes itself with PCIe 5.0 x2 support, offering future-proofing if your next motherboard supports it. The SN770 is slightly faster in sequential writes and often priced competitively, while P41 Plus tends to be cheaper but slower. Choose the 990 EVO if you value power efficiency and Samsung Magician's ecosystem, or if you plan to upgrade to a PCIe 5.0 platform soon.

Things to Consider

The PCIe 5.0 x2 mode requires a compatible motherboard; older boards will fall back to PCIe 4.0 x4, which still provides excellent performance but negates the future-proofing aspect. If you already have a PCIe 4.0-only system and don't plan to upgrade, you might save money with a SN770 or similar. The lack of DRAM cache is rarely noticeable in everyday use, but under prolonged heavy writes (e.g., transferring hundreds of gigabytes), write speeds may drop. For workstation-class workloads, a DRAM SSD is safer. Price wise, ¥69,947 is a bit higher than launch MSRP; keep an eye out for sales on or other retailers. The 990 EVO is not PS5 compatible due to its PCIe 5.0 x2 mode, so console users should look at PCIe 4.0-only drives. ## FAQ Q: Can I use the 990 EVO as a boot drive in a Ryzen 5000 system? A: Yes, it works perfectly in any motherboard with an M.2 NVMe slot supporting PCIe 4.0 or 5.0. On a Ryzen 5000 (AM4) board, it will operate at PCIe 4.0 x4 speeds.
