Thunderbolt started at 10Gbps, with a throughput of 700MBps to 800MBps, and today’s Thunderbolt 3 is specified for up to 40Gbps or 5,000MBps of bandwidth. For this comparison, I tested a 1TB Thunderbolt 3 external SSD, a 1TB USB 3.1 Gen 2 external SSD, and a 1TB NVMe SSD that I installed into a USB 3.1 Gen 2 external enclosure. If you're concerned about crowdsourcing projects, it might be better to wait and see if the GigaSSD team delivers.The ports themselves are backwards compatible, so a Thunderbolt 3 port will work just fine with drives that use the slower interfaces. Heck, if you want to save money, you should also consider it. If you own one of the growing number of Apple M1 computers, consider the GigaDrive for your backup needs. You want a large capacity external drive.You have an Apple M1 device that supports Thunderbolt 4.Prices often fluctuate, depending on market conditions. When looking for a drive, it's important to look at the price per TB to comparison shop. However, some of the best external hard drives support Thunderbolt 3, including our favorite, the LaCie Rugged Thunderbolt (4TB). GigaSSD GigaDrive: CompetitionĪt the time of this writing, there are no Thunderbolt 4 external drives on the market. And yet, as someone who has been burned a few times with crowdsourcing, understand there's always a risk. There's no reason to believe the first GigaDrive models won't ship as scheduled in just a few weeks. Still, others do eventually get released, but not in the timeframe the creators originally promised. Indiegogo projects make many nervous, and with good reason since some never get off the ground leaving crowdsourcers out to dry. My only other concern about the GigaSSD GigaDrive should go away in July once the first units arrive. Indiegogo projects make many nervous, and with good reason, since some never get off the ground This only becomes a negative if you decide to hold the SSD in your hand (you shouldn't) or place it on a heat-adverse surface. This might be the case, and yet, the GigaDrive is still very hot to the touch when it's working. GigaSSD's Indiegogo website mentions that the GigaDrive was designed to be "anti-overheat protected" since transferring large amounts of data can cause overheating. The included cable measures just under 18 inches. We didn't test this, however.įinally, kudos to GigaSSD for shipping the drive with a cable long enough that there's breathing room between it and a computer. Additionally, its anodized metal makes it durable enough to continue to work even after an accidental fall of up to 10 feet, according to GigaSSD. IP67-rated means an occasional coffee or water drop isn't going to hurt this beast. Overall, I was happy with the GigaDrive's speeds but will leave it to the storage experts to look into this further.ĭurability is another area where the SSD shines. Performance numbers are probably better on GigaDrives with more storage, which you should keep in mind. We recorded two separate 10GB transfers at around 305MBps and 300MBps, respectively. Like TechRadar, however, we found that speeds weren't nearly as great under real-world conditions but still good. AS SSD: 1869MBps (seq read) 1711MBps (seq write).CrystalDiskMark: 2804MBps (read) 2538MBps (write).Its tests confirmed the drive is blazing fast: We didn't do benchmark tests on our 1TB GigaSSD GigaDrive review unit since our friends and fellows over at TechRadar already took care of those.
