USB Flash Drives
USB Flash Drives holds removable flash media: USB sticks from Kingston, SanDisk and Samsung, SD, microSD and CompactFlash cards, and server boot devices such as HPE's dual-microSD RAID 1 USB boot drive (P21868-B21) that ProLiant servers use to run a hypervisor. A share of the older listings are small embedded flash modules that shipped inside network gear and servers, so check that a part is a standalone drive and not a component made for one system.

Buying guide
Flash media for servers and the field
Hypervisor boot devices
Recent VMware ESXi releases discourage SD- and USB-only boot because of write wear. Mirrored boot devices or M.2 boot modules are the usual replacement in newer servers.
Embedded flash
CompactFlash and small flash modules inside routers and controllers hold firmware. Replace them with the OEM part so the device recognizes the media.
Endurance
Cheap sticks and cards are built for occasional copies, not constant logging. Use high-endurance media anywhere data is written continuously.

Frequently asked questions
What is a dual microSD boot device?
A small module holding two microSD cards mirrored in RAID 1, so a server can keep booting its hypervisor if one card fails. HPE's P21868-B21 is an example.
Can I copy a router's CompactFlash card to a new one?
Usually yes, if the replacement is the same capacity or larger and the device supports it, but the OEM part avoids compatibility surprises with picky firmware.
