The best 2TB SSD with DRAM keeps its speed steady when you install big games, copy large folders or run heavy workloads. A DRAM cache stores the drive's mapping table in fast memory, so the controller does not have to fetch it from slower flash or borrow system memory.
Many fast SSDs now skip DRAM to save cost and power, and makers do not always say which is which. For this guide we only included 2TB drives whose Amazon listing explicitly states a DRAM or DDR4 cache, checked on October 11, 2026. Scores are our editorial scores out of 10, not Amazon customer ratings.

Lexar 2TB NM1090 PRO NVMe SSD, PCIe Gen 5, M.2 2280
DRAM and SLC cache with Gen5 speed: reads up to 14,000MB/s and writes up to 13,000MB/s, plus DirectStorage support.
Kingston FURY Renegade G5 2TB NVMe SSD, PCIe 5.0 M.2 2280
Low-power DDR4 cache with a 6nm SM2508 controller and rated reads up to 14,800MB/s, the fastest DRAM drive here.
Acer Predator GM9000 2TB SSD, PCIe Gen5x4 NVMe, SLC + DRAM Cache
A Gen5 drive with SLC and DRAM cache, reading at up to 14,000MB/s and writing at up to 13,000MB/s.
Acer Predator GM7000 2TB NVMe SSD with DRAM Cache, PCIe Gen4x4
The best DRAM pick for Gen4 systems, with TLC NAND, a heat spreader and reads up to 7,400MB/s.
TEAMGROUP T-Force GA PRO 2TB Gen5 SSD with DRAM Cache and Graphene Heatsink
An entry Gen5 drive with DRAM and SLC cache, 3D TLC NAND and a patented graphene heatsink, reading at up to 10,000MB/s.
Ediloca 2TB PCIe Gen4 NVMe SSD with Heatsink and 2GB DRAM Cache
A lesser-known brand, but the listing confirms up to 2GB of DRAM, a heatsink, 3D TLC NAND and a 1,400TBW rating.
In-Depth Reviews
1. Lexar NM1090 PRO 2TB: Best Overall
The Lexar NM1090 PRO 2TB combines a DRAM cache with an SLC dynamic cache and a 6nm controller. It reads at up to 14,000MB/s and writes at up to 13,000MB/s, and Lexar lists Microsoft DirectStorage support.
It was the best balance of DRAM, speed and price among the Gen5 drives we checked.
2. Kingston FURY Renegade G5 2TB: Fastest DRAM Drive
The Kingston FURY Renegade G5 2TB uses low-power DDR4 cache with the 6nm SM2508 controller and a 12-layer PCB. Kingston rates it for reads up to 14,800MB/s and writes up to 14,000MB/s.
It is the fastest drive here on paper and carries a 5-year manufacturer warranty, but cost more than the NM1090 PRO in our check.
3. Acer Predator GM9000 2TB: Best Acer Gen5 Pick
The Acer Predator GM9000 2TB lists both SLC and DRAM cache, with reads up to 14,000MB/s and writes up to 13,000MB/s on PCIe 5.0 x4.
Its Amazon listing is short on other details, and it was the most expensive Gen5 drive in this list when we checked.
4. Acer Predator GM7000 2TB: Best Gen4 with DRAM
For PCIe 4.0 systems, the Acer Predator GM7000 2TB pairs a DRAM cache with 3D TLC NAND and a heat spreader. It reads at up to 7,400MB/s and writes at up to 6,700MB/s.
It has a 5-year limited warranty. For PS5 use, add a proper heatsink, as Sony's PS5 M.2 SSD guide requires one.
5. TEAMGROUP T-Force GA PRO 2TB: Best with Graphene Heatsink
The TEAMGROUP T-Force GA PRO 2TB lists DRAM cache, SLC cache, 3D TLC NAND and a patented graphene heatsink. It reads at up to 10,000MB/s and writes at up to 8,500MB/s.
It is slower than the other Gen5 picks, and the listing names desktops as the compatible device type.
6. Ediloca 2TB Gen4 with DRAM: Best Gen4 DRAM with Heatsink
The Ediloca 2TB Gen4 DRAM SSD listing confirms up to 2GB of DRAM, an aluminum heatsink, 3D TLC NAND and a 1,400TBW rating, with reads up to 7,400MB/s.
Ediloca is a smaller brand with a shorter track record than the others, so weigh that against its feature list.
How to Choose the Best 2TB SSD with DRAM
What DRAM Does
The DRAM cache holds the map of where data lives on the flash. With it, the drive finds data quickly even during long, mixed workloads.
DRAM vs HMB
HMB (Host Memory Buffer) drives borrow a small amount of system RAM instead. They load games very well and use less power, but DRAM drives usually hold speed better in long transfers.
Do Gamers Need DRAM?
For loading games, not strictly. DRAM helps most if you install or move large games often, record gameplay, or edit video on the same drive.
Confirm It on the Listing
Many listings do not mention cache at all. We only included drives where DRAM is stated; if a listing is silent, do not assume.
Prefer Low Power?
For laptops, efficient HMB drives can be the better choice. See our best 2TB SSD for gaming laptop guide.
Quick Setup Tips
- Match the slot: Gen5 DRAM drives need a Gen5 slot for full speed
- Cool it: use a heatsink, especially on Gen5 drives
- Leave free space: keep some space free so the SLC cache can work
- Update firmware: check the maker's site or software after installing
- Check warranty terms: some warranties end at a TBW limit before the time limit
Frequently Asked Questions
What is the best 2TB SSD with DRAM?
The Lexar NM1090 PRO 2TB, with DRAM and SLC cache and Gen5 speed.
Is a DRAM SSD better for gaming?
Load times are similar to good HMB drives. DRAM helps more with long installs and big file transfers.
What is the best Gen4 2TB SSD with DRAM?
The Acer Predator GM7000 2TB, with DRAM cache, TLC NAND and a 5-year warranty.
Why don't all SSDs have DRAM?
DRAM adds cost and power. Many modern drives use HMB to save both while staying fast.
Does the Samsung 990 PRO have DRAM?
We left it out because its Amazon listing does not state the cache type, and we only included drives with DRAM confirmed on the listing.
The Bottom Line
The Lexar NM1090 PRO 2TB is the best 2TB SSD with DRAM for most Gen5 builds, the Kingston FURY Renegade G5 2TB is the fastest, and the Acer Predator GM7000 2TB is the best DRAM choice for Gen4 systems.
