![]() r/hardware IS NOT the place to come for help of any kind. The current one is notoriously fragile and far too chunky for a thinner, nimbler drive.The goal of /r/hardware is a place for quality hardware news, reviews, and intelligent discussion. We would love to see a smaller version of the drive – a physically smaller model that is – something that should be possible if the next iteration adopts a USB Type-C connector. They represent a 50% improvement on the chip used in the SD700 which means that a 2TB model is likely to appear later this year. Moving forward, Toshiba/Western Digital now have 512GB 64-layer 3D NAND chips in their portfolios with IMFT and Samsung likely to follow suit within a few months. You still pay a premium compared to the SU800 (about 17%), which is essentially the same drive, and that’s slightly annoying but then the SD700 targets a niche. The margin is even wider when compared to LaCie’s rugged SSD range. Early verdictĪt just under £153 (around $190, AU$250) at the time of writing, this portable drive is slightly less expensive than the likes of the Samsung T3 or the SanDisk Extreme 500 while offering an extra 12GB and 32GB respectively. Other than the NAND chips, there’s also a single Nanya NT5CC256W DRAM chip, which could either be a 256MB or a 512MB DDR3 buffer. Should you want to open the drive, the two parts of the shell come off using a flat screwdriver. In our benchmarks using CrystalDiskMark, the SD700 hit 433MBps and 427MBps in read and write speeds respectively, which is about an order of magnitude faster than magnetic hard disk drives.Ĭompared to the SU800 though, which reached 563/508MBps in the same benchmark, it is a bit of a disappointment – although an expected one because of the limitations of USB and the overhead associated with having a USB-to-SATA bridge. The SD700 supports AES 256 Encryption and users can use this function through ADATA's “HDDtoGO” which can be downloaded from the website. A Type-C connector might have been preferable since most new high-end laptops come with these.Īdata throws in a three-year warranty, a rather thick but short cable, as well as a few software goodies including Macrium Reflect backup suite, an SSD toolbox, Acronis True Image HD and OS to Go. It connects to any host computers using a USB Type-A connector (v3.1 gen 1) meaning that the maximum theoretical transfer limit is 5Gbps, the same as that of v3.0. Switching to 3D NAND ensures that the drive consumes even less power per unit storage, packs more bits per unit volume and heats up less (it was barely warm during our tests). That meant teaming the Silicon Motion SMI SM2258 controller with IMFT’s 384Gbit TLC 3D NAND flash modules and what Adata describes as a DRAM cache. It makes sense for Adata to use the same components to make the most of economies of scale. The drive is protected by a non-removable rubber ring and the electronics are enclosed by an aluminium chassis, with the ADATA logo and the word SSD displayed prominently on top, and a blue status light just below.ĬrystalDiskInfo recognised the drive as being the SU800 which we reviewed last year. A proper ruggedized storage drive if you’re looking for one. In other words, assuming that the USB port cover is firmly closed and secured in place, this is one of the most solid high capacity devices you can buy. It’s also tested to military grades (MIL-STD-810G 516.6) to withstand shock even when in use (although the cable might become loose or the connector might break).
