Internal DVD writer for legacy media

The Pioneer DVR-S21WBK is a 5.25 inch internal drive that writes and reads CD and DVD formats only. It suits users who still archive data to optical discs or install software from physical media. Blu-ray discs are not supported by this model.

SATA I interface decides compatibility

The drive connects through a Serial ATA Gen.1 port, the original SATA I standard. Motherboards with only newer SATA revisions will still accept the drive, but the link will negotiate at the slower Gen.1 rate. Systems lacking any SATA connector cannot use this unit.

Writes DVD at 24x and CD at 48x

Dual-layer DVD±R discs record at 8x while DVD-RAM reaches 5x. Rewritable DVD±RW media tops out at 6x and CD-RW at 24x. The 0.5 MB buffer helps prevent underruns during sustained burns, though very high-speed media may still hit the drive's firmware limits.

商品問答

What does the 24x DVD write speed mean once the drive is installed in a PC?

The drive can write single-layer DVD+R and DVD-R discs at up to 24x, dual-layer media at 8x, and DVD-RAM at 5x, with actual throughput limited by the SATA I interface and disc quality.

Which interface does this burner use and what does it limit in practice?

It uses a SATA I connection, so the host link runs at Serial ATA Gen.1 speed and the 0.5 MB buffer helps sustain streaming writes without overrunning the bus.

What does the drive need to fit and mount in a standard case?

It fits a 5.25 inch front bay, mounts horizontally or vertically with the four included screws of 5 mm or less, and requires a SATA data and power cable from the motherboard and PSU.
