First, if you are connecting an SSD to your Windows 7 PC via an external dock (USB 3, Firewire 800 or eSATA), be forewarned that the drivers for these docks may preclude formatting your SSDs as anything but NTFS from the Windows 7 GUI. I assume that the BMC will also be able to access both format types. The BMD Hyperdeck software Version 3.5 was released today, allowing the Shuttle and Studio units to read read not only HFS SSDs, but also exFAT formatted SSDs. (In Mac OS X, TRIM is only supported for Apple-supplied SSD drives).Note, that this post is only indirectly related to the BMC, since most of you do not have a camera in hand.
Otherwise, even if you don’t see any data and the disk appears empty or inaccessible, the TRIM command is not issued until you do the formatting or repartitioning). (TRIM is only issued if you explicitly delete a file, format or repartition the disk.
The disk or the file system is corrupted. Your SSD drive is formatted with FAT, FAT32 or exFAT. (TRIM was added to Windows 7 and newer, including Windows 8 and 8.1). Even today, TRIM and RAID may not work together). (Until recently, Windows did not support TRIM on RAID arrays. You used two or more SSD drives in an internal RAID array. (Most NAS units do not support TRIM, with the exception of some Synology units coupled with latest OS). You used one or more SSD drives in a NAS enclosure. You used an SSD drive in a USB enclosure. In particular, TRIM will not work if any of the following is true: However, in some situations TRIM does not engage. Without TRIM, you would get much slower write speeds and much faster wear of flash cells, which have a limited number of write cycles before failing. TRIM is a great thing to optimize performance and longevity of an SSD drive. More often than not, your files will still be there on the SSD drive, ready to be recovered. Sounds scary, doesn’t it? However, this is not always the case. In the first article called “ How SSD Drives Permanently Erase Deleted Data” we described the reasons for SSD drives to erase your data permanently as soon as you erase a file, quick-format the disk or delete a partition.
