TL;DR / At a Glance: Samsung 990 SSD delivers 7.2GB/s read, 38% more efficient than 990 PRO. Available in 1TB (RM1,069) and 2TB (RM2,111) in Malaysia from end-July 2026. DRAM-less, HMB design cuts cost without killing performance.
Samsung just dropped the 990 SSD in Malaysia. No flash, no hype, just the facts: 7,250 MB/s sequential read and 38% better power efficiency than its predecessor.
This isn’t a flagship. It’s not trying to compete with Gen5 drives or AI model loaders. It’s the mainstream Gen4 SSD you buy when you want speed without the price tag.
Let’s break it down:
Sequential read hits 7,250 MB/s on the 2TB model. The 1TB drops to 7,150 — not much, but that’s a legacy 990 EVO Plus number, so we’re not chasing speed gods here.
Random IOPS? 850K read / 1,200K write on 2TB. That’s decent for a daily PC or light creative work. If you’re running a 4K editor or gaming studio setup with 100+ titles, you’ll notice lag. But for most of us? This is where it stops being a gimmick and starts being useful.
The 38% power efficiency gain is real. Based on Samsung’s own internal test, the 990 uses 1,686 MB/s per watt for reads, versus 1,221 MB/s per watt on the 990 PRO. That’s significant when you’re running a 24/7 machine in KL traffic or during a tropical downpour.
And the DRAM-less HMB design? That’s a big deal. Most people assume DRAM cache = better SSD. Wrong. Thanks to HMB (Host Memory Buffer), Samsung reserves 64MB of your RAM as a cache. It’s not magic — it’s just smarter engineering. Most of us have 8GB anyway, so it doesn’t steal anything. You lose maybe 2 seconds of boot time, but you save hundreds of ringgit.
TBW endurance? 400TB (1TB) and 800TB (2TB). That’s good for local storage, but if you’re doing AI model training with a GPU, you’ll need to plan ahead. It’s not built for 10 years of heavy writes.
It doesn’t have the same raw speed as the 990 PRO or Gen5 9100 Pro. That’s the point. This isn’t about being the fastest dog. It’s about being the dog that doesn’t bark too loud when you want to play fetch.
So for who?
- Gaming rigs: You can fit 30 large AAA games on a 2TB unit. Average game size is ~64GB (based on Steam’s best of 2025 list). That’s a real win.
- Creatives: Faster loading, better responsiveness. No more waiting for a 10GB file to sync across drives.
- Budget PC builders: It’s cheaper than most Gen4 drives. At RM1069 and RM2111, it’s priced right for local SEA markets.
It’s not perfect. It doesn’t beat the 990 PRO in random IOPS. It’s not Gen5. But for the average user? It’s a solid value play.
If you’re building your first PC, don’t skip this one. It’s the only Gen4 SSD that actually cares about efficiency while keeping the price low enough to ship to every corner of Malaysia.

Pricing and availability
The Samsung 990 SSD will be available in Malaysia in 1TB and 2TB models from end-July 2026, with an MSRP of RM1,069.00 and RM2,111.00, respectively.
Adam Lobo’s Verdict:
The 990 is a solid entry Gen4 drive. It’s not chasing the 990 PRO in raw numbers — it’s competing on efficiency and price. If you need top-tier random IOPS for AI or 4K rendering, go PRO. If you want a dependable, affordable drive for daily use or gaming? This is your guy.
