Apple Still Using SSDs With Varying Speeds on New MacBook Air
Engadget now points to a new video produced by TLD Today indicating that Apple is continuing to employ this dual-supplier strategy for SSDs in the new MacBook Air, with the Samsung SSDs continuing to provide substantially better performance than the Toshiba drives.
Jonathan over at TLD discovered a fairly significant discrepancy when benchmarking both MacBook Air models over the weekend. The 128GB Samsung SSD in his 11-inch Air was able to achieve 246 MB/s write and 264 MB/s read speeds. When he switched to the 13-inch model, however, speeds dropped to 156 MB/s and 208 MB/s, respectively, using that notebook's 128GB Toshiba SSD.The report indicates that users are unlikely to notice any difference in day-to-day usage between machines running the drives, although the substantial performance difference does suggest that it may be noticeable for certain high-intensity tasks.
