Solid-state drives (SSDs) have been mainstream for more than a decade now, managing to take the performance, reliability and power consumption crowns away from their hard disk drive cousins.
The latest SSD-related technology trickling down to the mainstream is 3D TLC NAND which is supposed to improve performance by cramming in even more transistors per unit volume, without any negative impact on power consumption or reliability.
The 3D nomenclature comes from the fact that transistor clusters are layered one on top of another. 48 layers is what the market is currently at, with 64 and 96 layers landing in the near future.
Adata unveiled this external SSD at the end of last year as part of its Premier range – it supersedes the existing SV620 and uses 3D TLC NAND memory chips produced by Micron/IMFT, and is available in 256GB and 512GB versions.
The smaller model is priced at around £100 (about $125, AU$160) with the bigger one on sale for around £180 (about $230, AU$295). The drive is likely to use the Silicon Motion SM2258 controller, the same one found on the SU800 (internal) and the SD700 (rugged), both of which we reviewed fairly recently.
