Plextor teased us with its M7e - a PCIe SSD we've seen on display several times since 2014's Flash Memory Summit - yet again. In its current form, the M7e looks identical to the M6e except for a lit PCB that adds some etched Plextor branding to the top side. We're not sure if Plextor plans to use Marvell's Eldora or Eldora Lite controller, but we suspect the four-channel Eldora Lite will be called to the plate for this product.
Tagging along in the M7 product series is the M7V, a Toshiba A19 TLC-based drive with a Marvell controller. Parent company Lite-On displayed a similar SSD in Marvell's display area with Lite-On branding. The M7V looked production-ready with all of the features working, including the advanced software. Both the M7e and M7V should launch in August at Flash Memory Summit.

Plextor continues to advance PlexTurbo with new features. PlexTurbo 3 raises the bar by allowing users to adjust the amount of DRAM dedicated to the storage buffer. If your workload requires more DRAM for system applications, the software will automatically release RAM back to the system and reclaim it when available for cache purposes again.
PlexCompressor is the most innovative software feature to come out of Plextor since its bit-for-bit optical disc cloning technology, which was introduced more than a decade ago in PlexTools. The software will automatically compress the files on your computer if the data hasn't been accessed in 30 days. This can lead to a massive reduction in file size. In the past, I've shown that SSD performance drops with more data on the flash. PlexCompressor will reduce the amount of used space to keep performance higher. When the data is needed, it is decompressed in real time. If the technology works as well as Plextor claims, it could be the next leap in SSD software.
SSDs are still no archival media, and they will corrupt after a year or two without power. But if you are the sort of person who travels a lot and unplugs your PC for 2-3 months at a time then it is not a real concern anymore.
I'm so out of touch that I didn't even know that was "a thing"
Really? 5 years ago? Because I've gone on vacation for about a month and my Windows wont even start anymore. And that was about a year ago. Heard a rumor that the 3D stacking technology thing managed to eliminate this problem and i was waiting for some more good news about that before buying a new SSD.
A $60 240GB SSD is the reason why you don't feel a big performance increase over your HDD.
But how old was the SSD? The model, not the particular one that you own.
