Using SSD in FreeBSD

Now that SSD drives are becoming mainstream, I had a few questions on installing a SSD drive in a FreeBSD environment. Can FreeBSD be made SSD aware, that is, somehow let FreeBSD know that reads and writes should be limited or deferred to extend the disk's life? Is there a setting for wear levelling? Also, for large databases, is SLC or MLC recommended?

Thanks in advance

RAID 0 for SSD

Nowadays the fastest SSDs achieve read-speeds of between 1500 MB/s to 1900 MB/s. Let's say that two such SSDs in RAID 0 achieve roughly double the throughput, ie 3000 MB/s. That is only half an order of magnitude removed from RAM ((10)^(1/2) * 3000 = 10.000), very broadly speaking. So for the... (6 Replies)

VPO(4)							   BSD Kernel Interfaces Manual 						    VPO(4)

NAME
vpo -- parallel to SCSI interface driver SYNOPSIS
device vpo For one or more SCSI busses: device scbus DESCRIPTION
The vpo driver provide access to parallel port Iomega Zip and Jaz drives. HARDWARE
The vpo driver supports the following parallel to SCSI interfaces: o Adaptec AIC-7110 Parallel to SCSI interface (built-in to Iomega ZIP drives) o Iomega Jaz Traveller interface o Iomega MatchMaker SCSI interface (built-in to Iomega ZIP+ drives) USAGE
The driver should let you use a printer connected to the drive while transferring data. DOS and FreeBSD file systems are supported. When mounting a DOS file system or formating a FreeBSD file system, check the slice of the disk with the fdisk(8) utility. In order to unixify a ZIP disk, put the following in /etc/disktab: zip|zip 100: :ty=removable:se#512:nc#96:nt#64:ns#32: :pa#196608:oa#0:ba#4096:fa#512: :pb#196608:ob#0:bb#4096:fb#512: :pc#196608:oc#0:bc#4096:fc#512: and use bsdlabel(8). If you have trouble with your driver, your parallel chipset may not run properly at the detected mode (NIBBLE, PS2 or EPP). Tune the ppc(4) bootflags to force other modes. SEE ALSO
da(4), lpt(4), ppbus(4), ppc(4), scsi(4) HISTORY
The vpo manual page first appeared in FreeBSD 3.0. AUTHORS
This manual page was written by Nicolas Souchu. BUGS
During boot, the driver first tries to detect a classic ZIP, then a ZIP+. The ZIP+ detection is intrusive and may send erroneous characters to your printer if the drive is not connected to your parallel port. BSD
