Continuing in the vein of solid-state drive price cuts, Newegg has the Adata SP900 Premier Pro 256GB 2.5" Internal SATA III Solid State Drive for $149.99, including free shipping after a rebate.

To be clear, the company charges sales tax in Calif., NJ, and Tenn. To compare with Newegg's giant rival,, that Internet retailer has the ADATA USA Premier Pro2.5-Inch 256GB SATA III for $169.99.

This deal is good for one day only, and can be found here. The rebate -- which comes directly from ADATA -- can be found slightly below the Add to Cart button, or here.

In terms of pure pricing, Newegg was already beating, with a $159.99 price before rebate.

Consumers will find a metal 2.5" to 3.5" bracket in the box, if they decide they want to install this SSD in a desktop pc, rather than a laptop. Along with the drive and the bracket, they will also find a copy of Acronis True Image HD to make it easier to migrate their OS and files to the new SSD.

Note: while it's true that -- considering the small size of the drive -- relatively speaking, of course, as there were days when 256GB was considered huge -- most folks will use this as a boot drive with a secondary regular mechanical hard disk drive as a data storage location, we'd probably want to start clean rather than migrate.

Don't get us wrong, migration is easier. However, as many know, over time, Windows will get clogged up with dross and extra files leftover from installs and upgrades. It's always a good idea to start from scratch every once in a while.

Among the technical specifications that many will find interesting, ADATA says that the drive will support up to 550MB/s read speeds and up to 520MB/s write speeds. The phrase up to should of course be noted.

Meanwhile, the drive also has the required (nowadays) SMART support and the required (for SSDs) TRIM support.

S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) was developed by hard drive manufacturers, and is a technology that enables the user to determine a hard drive's reliability and status.

TRIM, on the other hand, is exclusive to SSDs. The low-level operation of SSDs differs significantly from standard hard drives, and after they became popular, it became clear that the typical way in which OSes handle operations such deletes and formats resulted in unanticipated progressive performance degradation of write operations.

TRIM marks blocks of data which are no in use, telling the drive controller and the OS (assuming it supports it) 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 "old days," delete operations were typically limited to flagging data blocks as "not in use" in the file system. However, for SSDs, a command, TRIM, must be sent to indicate to the drive that those blocks are no longer used.

Interesting? Perhaps not, but it is important that a drive and OS support TRIM. Again, the rebate expires on Sept. 19.
