Crucial 4TB SSD

The Crucial BX500 4TB is a budget SATA SSD that maxes out the SATA III interface at 540 MB/s read and 500 MB/s write. It's DRAM-less, so random performance is weak, but for storage and everyday use in older systems, it's a reliable and affordable 4TB option. Shop around, because US prices range from USD 479 to USD 649 for the same drive.

Sequential numbers are 540 MB/s read and 500 MB/s write, which is basically the ceiling of the SATA III interface. You won't get more from any SATA drive, so in that context the BX500 is maxing out what the connection allows. But compared to the broader SSD market, including NVMe drives, this lands in the 26th percentile for speed. That's not a knock on Crucial specifically, it's just physics. SATA is old tech at this point.

Random performance is where the DRAM-less design shows up. The BX500 sits in the 23rd percentile for random operations, which means it's near the bottom of the pack when compared against modern SSDs. In practice, that translates to slightly longer load times in games and a bit more hesitation when multitasking compared to a DRAM-equipped SATA drive or any decent NVMe drive. For a boot drive in an older laptop, it's still a massive upgrade over a spinning hard drive. But if you're putting this in a system with an M.2 slot, you're leaving performance on the table.

Endurance is rated at 1000 TBW with a 1,500,000 hour MTBF and a 3-year warranty. That's middle of the pack for endurance, 67th percentile, which is respectable for a budget drive. You'd have to write roughly 913 GB per day for three years to hit the TBW limit, so for typical home use, this drive will outlive the computer it's installed in.

The BX500's natural competitors are other SATA SSDs, but the data we have puts it up against some heavy hitters. The Samsung 9100 PRO, Western Digital WD_BLACK WDS800T2XHE, Kingston FURY Renegade SFYRDK/4000G, Micron T710 CT4000T710SSD5, and SanDisk Black SN850X WDBB9G0040BNC-WRSN are all NVMe drives, and they all destroy the BX500 in raw speed. The WD_BLACK and Samsung drives are PCIe 4.0 parts with read speeds several times higher than 540 MB/s. But here's the thing: those drives are also more expensive and require an M.2 slot. The BX500 isn't trying to compete with them on speed. It's competing on compatibility and capacity.

Against other SATA SSDs, the BX500 holds up fine. The Samsung 870 EVO is the obvious alternative, and it has DRAM, which gives it better sustained write performance and random I/O. The 870 EVO also carries a 5-year warranty versus the BX500's 3-year. But the 870 EVO typically costs more per gigabyte. If you're just storing games or media and doing light productivity work, the BX500 gets you to 4TB for less money. If you're running an OS and doing anything write-heavy, the 870 EVO is worth the premium.

Value is where the BX500 gets interesting, but only if you shop carefully. In the US, the same drive lists anywhere from USD 479 to USD 649. That USD 170 gap is absurd, and paying the high end would be a mistake. Amazon currently has the lowest US listing at USD 479, and that's the one to look for. In Europe, the spread is EUR 535 to EUR 648, so the same advice applies. At the low end, you're getting 4TB of TLC NAND for a reasonable price per gigabyte. At the high end, you're overpaying for SATA technology that hasn't gotten faster in a decade. If you need 4TB and your system only has SATA, this is one of the cheapest ways to get there. If you have an M.2 slot, a budget NVMe drive will cost similar money and run circles around this thing.

The Crucial BX500 4TB is a 2.5-inch SATA III internal SSD aimed at people who want a big chunk of storage without spending NVMe money. It sits in the budget end of the SSD market, and the whole pitch is simple: 4TB of TLC NAND in a drive that works with just about any laptop or desktop with a SATA port. No adapter, no heatsink, no fuss. Crucial's own marketing leans on the idea of breathing new life into older machines, and honestly, that's exactly where this drive makes sense.

People searching for a 4TB SSD for laptops or desktops will find the BX500 easy to recommend on paper. It's DRAM-less, which is worth knowing up front. That design choice keeps the price down but has real implications for sustained write performance. For everyday use, booting Windows, loading games, storing a massive media library, it's fine. For heavy workstation tasks, you'll feel the ceiling.

Pricing is all over the place depending on where you shop. In the US, we're seeing listings from USD 479 to USD 649 across five vendors. That's a USD 170 spread for the exact same drive. In Europe, EUR prices range from EUR 535 to EUR 648. Shop around before you buy, because paying the high end of that range makes no sense when the low end exists.

Skip the BX500 if your system has an M.2 slot, because a budget NVMe drive will cost about the same and run several times faster. Skip it if you do sustained write-heavy work like video editing, large file transfers, or running virtual machines, the DRAM-less design will choke under those loads. Skip it if you want a long warranty, since 3 years is shorter than the 5 years Samsung offers on the 870 EVO. And skip it if you're not willing to shop around, because paying USD 649 when the same drive is USD 479 on Amazon is just throwing money away.

Should you buy the Crucial BX500 4TB? If you have an older laptop or desktop with only SATA ports and you need a big storage upgrade, yes, this is a solid choice. It's easy to install, it's reliable enough for home use, and 4TB is a lot of room. The 4.5-star rating across 1265 reviews backs that up. Owners consistently mention easy installation and good speed for a SATA drive, and several say they're planning to buy another one.

But if your system has an M.2 slot, skip this and get an NVMe drive. The speed difference is not subtle, and the price gap has narrowed enough that SATA only makes sense when you have no other option. Also, if you're doing heavy video editing or running databases, the DRAM-less design will frustrate you. This is a storage drive, not a performance drive. Know what you're buying, and you'll be happy with it.
