Lexar’s NM1090 Pro is a quick SSD within the total scheme of issues. However, it’s on the sluggish facet for a PCIe 5.0 SSD sporting DRAM, whereas costing roughly the identical because the quicker competitors. That locations it firmly within the buy-at-the-right-discount class.
Read on to be taught extra, then see our roundup of the best SSDs for comparability.
What are the Lexar NM1090 Pro’s options?
The specs for the NM1090 Pro sound implausible: PCIe 5.0, 1GB of DRAM per TB of capability, 232-layer TLC NAND, and a Silicon Motion SM2508 controller. The 2280 (22mm broad, 80mm lengthy) form-factor drive additionally carries a barely greater than standard 700TBW per TB of capability score to mitigate its five-year guarantee.
TBW is roughly the assured terabytes that could be written to an SSD earlier than it goes into read-only mode. However, these are considerably cynical numbers designed to keep off guarantee abuse comparable to utilizing client SSDs in high-traffic servers.
How a lot does the Lexar NM1090 Pro value?
Lexar quoted us $180 for the 1TB capability drive, $270 for the 2TB capability, and $495 for the 4TB capability we examined. However, the 1TB and 2TB capacities have been on sale on Amazon for $139.49 and $224.49, respectively. Oddly, the 2TB model with a beefy heatsink was solely $219.49.
All of these costs are roughly on par for a PCIe 5.0, NVMe SSD using DRAM. In different phrases, it’s not an excellent cut price, but it surely’s additionally not prohibitively pricier than the competitors. That means it’s all about efficiency…
How quick is the Lexar NM1090?
Generally talking, the NM1090 Pro carried out nicely — although, once more, not fairly as quick as a lot of the PCIe 5.0/DRAM competitors. There was additionally the occasional inconsistency: a sluggish efficiency in our 450GB write and wildly uneven performances in AS SSD.
We did see some extraordinarily various performances in a single check session, however that was seemingly the fault of the then state of our check mattress which was recovering from a nasty R-Drive Image backup.
The NM1090 Pro was barely slower than the competitors in sequential transfers, as evidenced by the CrystalDiskMark 8 outcomes proven under.
The NM1090 Pro was inside shouting distance of the competitors in CrystalDiskMark’s random assessments. These are nonetheless a lot better 4K outcomes than what you’ll see with PCIe 5.0 HMB (host reminiscence buffer) designs. DRAM helps.
The 48GB switch time under is the perfect case situation — i.e., the quickest time the NM1090 turned in. On a number of events throughout our first look, the 48GB single file write was far slower.
The NM1090 Pro’s 450GB write time caught us off guard. The NM1090 I examined was a 4TB drive and may’ve been way more aggressive with the XPG Mars 980 Blade and Samsung 9100 Pro. And this was its quickest efficiency; different 450GB writes in our first session took nearly 4 minutes.
In the top, the NM1090 Pro completed 10th out of the 12 PCIe 5.0/DRAM SSDs I’ve examined. Lest you get the impression that it’s all unhealthy, I must also be aware that the NM1090 Pro continues to be 15th quickest total out of all 58 NVMe SSDs which have sat in our testbed.
Lower tier amongst its direct friends, however higher tier within the grand scheme issues.
Should you purchase the Lexar NM1090 Pro?
The NM1090 Pro carried out largely as marketed. However, the slowish 450GB write and barely subpar artificial benchmark performances place it behind the Samsung 9100 Pro, XPG Mars 980, and plenty of different PCIe 5.0 SSDs on our to-buy listing. Still, on the proper worth…
How we check
Our storage assessments presently make the most of Windows 11 (22H2) 64-bit working on a Z790 (PCIe 5.0) motherboard/i5-12400 CPU combo with two Kingston Fury 32GB DDR5 modules (64GB of reminiscence complete). Intel built-in graphics are used. The 48GB switch assessments make the most of an ImDisk RAM disk taking over 58GB of the 64GB complete reminiscence. The 450GB file is transferred from a Samsung 990 Pro 2TB, which additionally accommodates the working system.
Each check is carried out on a newly formatted and TRIM’d drive so the outcomes are optimum. Note that as any drive fills up, efficiency will lower as a result of much less NAND for secondary caching, and different components.
The efficiency numbers proven apply solely to the drive we have been shipped in addition to the capability examined. SSD efficiency can fluctuate by capability as a result of extra or fewer chips to learn/write throughout and the quantity of NAND obtainable for secondary caching (writing TLC/QLC as SLC). Vendors additionally sometimes swap parts. If you ever discover a big discrepancy between the efficiency you expertise and that which we report (programs being roughly equal), by all means — tell us.
