Another day, another "somewhere around $150" 240GB - 256GB solid-state drive deal, as eBay has the Crucial M500 240GB SATA 6Gb/s 2.5" Internal Solid State Drive, model number CT240M500SSD1, for a low $144.99.

The seller charges sales tax for items shipped to: New Jersey (7.0 percent) or New York (8.87 percent). The drives will ship from Elizabeth, New Jersey. Economy shipping is free. It is estimated that those on the West Coast would see an order made today on or before Tue. Oct. 29.

In terms of a price comparison, the deal isn't huge compared to say, Amazon.com. There the same drive sells for $149 with Amazon Prime shipping or free standard shipping. However, Amazon.com now charges sales tax in a number of states. Those shipping to California, for example, might see a much more significant savings, as they would have an addition $12 or so added on via sales tax.

We always tell eBay buyers to "let the buyer beware" and to check the feedback rating of any eBay seller. In this case, the seller, adoramacamera, is an Internet retailer in its own right, making it already someone you can, in general, trust. In addition, on eBay alone Adorama Camera has 199886 feedback ratings with 99.8 percent positive feedback. With this many deals, there is no way to maintain a 100 percent positive feedback rating, so this deal can be trusted.

The Crucial M500 240GB SATA 6Gb/s 2.5" Internal Solid State Drive, model number CT240M500SSD1, isn't the fastest drive. However, its specs say it is an enterprise level SSD, with a redundant array of independent NAND flash storage in the event of an uncorrectable error, power loss protection, 256-Bit AES encryption, 20nm MLC NAND flash, a Micron controller, up to 500Mb/s read, 250Mb/s write and 60,000 IOPS.

This is an MLC drive vs. a TLC drive (although technically, a TLC drive could still be labeled an MLC drive); TLC stores three bits per cell while the older MLC stores two bits per cell. The added bit adds latency, but then again, MLC has more latency than SLC (single bit per cell). However, TLC can be made cheaper than MLC for the same storage tier.

On the other hand, the Crucial drive is enterprise class, so rather than focusing on speed, it focuses on reliability and speed, together.

Those looking only at speed numbers should note other drive deals we have, with write speeds about double that of this drive. However, the read speed of this device are on par with other deals.
