SSDs vs. HDDs: When is all-flash storage overkill?
The SSD vs. HDD analysis isn't as simple as it looks. SSD prices are falling, and capacities increasing. But HDDs are still a good deal and fine for many noncritical workloads.
Does SSD overprovisioning have storage benefits?
While overprovisioned SSDs have less usable capacity available, that space is put to good use. The majority of SSD manufacturers overprovision their drives, and for good reason.
Charge trap technology advantages for 3D NAND flash drives
Flash drive cells based on charge trap technology are less likely to leak electrons than the older floating gate cell technology. But they have reliability issues to be aware of.
Pure Storage cloud plan gets warm reception from end users
Pure Storage made new FlashArray and FlashBlade all-flash systems generally available this week, emphasizing their role in moving data seamlessly between local and cloud storage.
How can SSD garbage collection help preserve drive speeds?
The rumors are true: SSD speeds can slow down over time. Luckily, there are processes available that can help prevent this from happening and maintain the speedy nature of SSDs.
