Transcend Ultimate 600X 128GB SDXC Memory Card Review

Transcend Ultimate 600X 128GB Memory Card Front

Introduction

The Transcend Ultimate 600X Class 10 128GB UHS-I SDXC card is a mid-level memory card aimed at those looking for good value and performance. The card is rated Class 10 and UHS Speed Class 1 (U1) which indicate it can provide at least 10MB/s continuous write speed. The 90MB/s speed rating only refers to the quoted maximum read speed. Transcend makes no specific claim about maximum write speed. Ultimate 600x memory cards are avaialble in 8, 16, 32, 64 and 128 GB capacities. The card tested here is a 128GB SDXC card (TS128GSDXC10U1). The 32GB Ultimate 600x card and 64GB card were tested previously.

Performance

The 128GB Transcend Ultimate 600x card was tested in various card readers. In sequential read benchamrks, the card reached up to 96.7 MB/s. This is better than the 90MB/s read speed claimed by Transcend. In sequential write speed tests the card performed up to 69.6 MB/s. This is better than expected for a card with no claimed maximum write speed other than the Class 10 and U1 designation that indicate it will reach at least 10MB/s. This performance is very close the more expensive Transcend 95/60 MB/s U3 128GB SDXC card, although that card carries the U3 rating (guaranteeing at least 30MB/s continuous write speed).

Random read and write tests varied in different card readers, and place the card slightly below the higher-level Transcend 95/60 MB/s U3 card.
