Review on 💾 Transcend 256GB JetDrive Lite 330: Expand MacBook Pro Retina Storage by David Richardson

Disclaimer: No Mac user has purchased SD media (and all forms, SDHC, SDXC, etc.) or really ALL flash media for a Windows laptop. Best-case layout: High-performance USB 3.0 READER media (external in almost all cases), High-performance USB 3.0 bus, USB 3.0 bus device only, USB 3.0 bus route to processor/memory (IE uses direct connection to processor lanes ) as short as possible. Best case results: I was able to get 92-94 MB/s READ (a continuous stream of file data) and 52-54 MB/s WRITE whether it was in the standard exFAT format or NTFS format . Considering the above, one of my laptops, which is fairly high end and uses an attached/supported USB 3.0 bus reader, was only able to get about 75-80Mbps READ and 35-40Mbps WRITE, a intended laptop I knew. was connected/capable of a USB 2.0 bus and only achieved about 33 MB/s READ and 20 MB/s WRITE (USB 2.0 speed specification with overhead is expected). Of course, I've tested it on multiple systems with different configurations, and that info isn't in the test above because I knew where the limitations were. Elsewhere, I can say that Transcend removes the speeds from the retail box based on reviews, but left the image with speeds, possibly due to a misunderstanding of how speeds work. I wasn't able to get the overall rated speed listed on the box picture, but I was pretty darn close to what's normal for multimedia cards these days.
