Price: More expensive portable SSDs can offer faster speeds, but you shouldn’t overpay to get extra speed or other features you may not notice.

As a result, you’ll still get the best speeds your computer can handle, and your drive will be able to keep up with newer devices in the future. 2 But all the drives come with either a Type-A adapter or a separate cable to ensure compatibility with the desktop PCs, laptops, gaming consoles, and tablets around your home. 1 USB-C connectors (video), which are replacing older, slower USB Type-A connectors on thinner laptops, ensure that you get the speed you’re paying for.

Connection type: For this review we primarily considered portable SSDs with USB Type-C (USB-C) connectors that were rated for USB 3.2 Gen 2 transfer speeds.

(Note that we don’t recommend the latter an internal solid-state drive is faster than an external drive, and with an internal drive you don’t have to worry about corruption from a cable getting disconnected.) Although fast sequential speeds are important for transferring and backing up large blocks of data to your drive, quick random speeds are essential if you must run programs or games directly off the portable SSD.

Drive speed: SSDs provide dramatically faster transfer speeds (less waiting for files to copy) than mechanical drives, and we tested both sequential and random speeds.

For example, we note when reviewers mention that their SSDs run hot too much heat during operation can shorten drive life or indicate that the drive is defective. Since SSD manufacturers don’t report durability ratings for external drives (only for internal models), we keep an eye on customer reviews for reliability information. But better endurance is a bonus, especially if you’re using the drive for high-intensity tasks such as 4K video editing. You’d have to write hundreds of terabytes of data to even begin to wear out most SSDs, though, and few people approach that limit.

Endurance: Flash-memory cells can be written to only so many times before wearing out.A portable SSD should also be sturdily built and not feel creaky or hollow. Since portable SSDs lack moving parts, they are less susceptible than mechanical drives to total failure when dropped, jostled, or subjected to changes in temperature or vibration. Reliability and toughness: A portable SSD must keep your data safe.Notes: Have the following items in the My Cloud S98user-start file to deal with sleep issues: /etc/init.d/wdmcserverd stopĬp /DataVolume/shares/xxxx/WD My Cloud/OS Backup Files/contentdir /etc/contentdirĬp /DataVolume/shares/xxxx/WD My Cloud/OS Backup Files/twonkyserver.ini /CacheVolume/twonkymedia/twonkyserver.

Have you tried connecting directly to WDM圜loud from your PC/laptop, i.e without going through any intermediaries? What are the performance results?įor those interested in my own stats, please refer to here: Have you tried different Ethernet cables? What about routers or switches? What are the read/write speeds for each test and what is the size of the file being transferred? Using SMB? FTP (did you test it internally? Or did you test it via DDNS from an external network?), Remote Access or any other methods? Is Content Scanning idle during your tests? Does your M圜loud constantly overheat? Does it go to sleep correctly? caching/content scanning disabled, DLNA/Twonky disabled, Netalk or iPV6 disabled, etc Ethernet cable type (Cat5e or Cat6, etc)Īny tweaks applied? E.g.Router Model (please clarify if you’re using a gigabit connection or not).I thought it’ll be a good idea if we can compile all the various results from different users into one post. I’ve also found a few posts on this forum regarding performance results, but it’s all over the place. I found it to be quite useful as this gives me something to compare my WDM圜loud against. I’ve found many articles online, showing performance results from e.g.

I’ve been having performance issues on my WDM圜loud lately, due to my recent upgrade to the latest firmware.
