Naturally we continue to state that customers need to make sure they are comfortable with the seller before pulling the trigger on an eBay deal. In this case, not only does the seller have a reputable feedback history, it's a retail site in and of itself, as well.

The eBay seller is Beach Camera, and of course, it has its own website, and as Amazon.com describes the company (a third-party reseller at Amazon.com):

Beach Camera and Electronics is a family-owned-and-operated company located in Green Brook and Edison New Jersey. Established in 1983 in the state of Maine, Beach Camera and Electronics was relocated to Green Brook New Jersey in 1991.

Beach Camera charges sales tax for items shipped to: N.J. (7.000 percent). The sales tax applies to the subtotal along with shipping and handling, again for N.J. only.

Beach Camera has 297787 feedback reviews, with an average feedback score of 99.4 percent positive feedback.

Beach Camera is listing the SSD as the Sandisk Ultra Plus 256GB SSD Global. It has the full part number SDSSDHP-256G-G25, which makes it analogous to this drive at Amazon.com) .

That drive is priced at $174.70, which means a buyer gets a $25 discount when compare to the giant Internet retailer.

SSDs are, of course, far faster than standard mechanical hard drivers, which must reposition a magnetic head in order to read data. None of that is necessary with an SSD, but there are other issues, instead.

The TRIM feature is a requirement for today's generation of SSDs. TRIM marks blocks of data which are no in use, indicating to the drive controller and the OS (assuming it supports it, as Windows XP -- for examplel -- does not) that the blocks can be wiped. Windows 7 and up supports this function.

TRIM is necessary because an SSD has no access to the file system structures of an OS. In the "good old days," delete operations were typically limited to flagging data blocks as "not in use" in the file system. However, for SSDs, the TRIM command must be sent to the drive to indicate to it that those blocks are no longer being used.

Interesting? Perhaps not, but it is important that a drive and OS support TRIM.

According to Sandisk's website, the 256GB (and 128GB) versions of this SSD can reachread speeds of up to 530MB/s.
